Remote Catheter Manipulation System (RCMS)
Robotic heart surgery a success April 29, 2010
Heart surgery using a remote-controlled robot has been carried out for the first time by surgeons at the University of Leicester.
70 year old Kenneth Crocker, retired postal worker and father-of-two was the first to undergo the successful operation to correct an irregular heartbeat.
A pioneering technology known as the Remote Catheter Manipulation System developed by Catheter Robotics Inc. has enabled a doctor to carry out a common heart treatment procedure remotely using a robotic arm.
The technique has enabled surgeons to operate from another room, taking away the risk of exposure from x-rays and the difficulties that many experience using lead aprons.
Dr Andre Ng, who carried out the operation at Glenfield Hospital said that it "went very well", pointing out that the entire procedure had been completed within an hour and the 70 year old patient was allowed to go home the next day.
Doctors think he'll be able to jog and tackle other light exercise in the next few weeks.
The procedure involved inserting thin wires, called catheters, into blood vessels at the top of the groin and through into the heart of the patient ....read more

UK Hospital set to go robotic for head and neck surgery April 29, 2010
Chosen as just one of five national Centers of Excellence, UK Chandler Hospital will serve as a training hub for surgeons to learn and use a new approach to head and neck surgery called the TransOral Surgical (TORS) procedure.
The da Vinci robot, which combines enhanced 3-D views with precise incision capabilities, is already being used for various types of surgery by UK Chandler Hospital and hundreds of other hospitals throughout the country and the world. However, it was just recently that the FDA approved using the da Vinci for the TORS procedure on head and neck cancers.
Dr. Raleigh O. Jones, chief of the Division of Otolaryngology – Head and Neck Surgery, said the designation of UK Chandler Hospital as a regional site for training and surgery in TORS is significant.
"The rates of this disease in Kentucky are exceedingly high in Kentucky," said Dr. T.J. Gal, a surgeon with the hospital's Division of Otolaryngology – Head and Neck Surgery, who will be coordinating the TORS surgical training program. "Now we have a revolutionary way to further benefit these particular patients."
Gal received his TORS training at the University of Pennsylvania from the very physicians who founded the new procedure and set up the world's first TORS program in 2004 — Gregory Weinstein and Bert O'Malley. After years of research and clinical trials, the procedure was approved by the FDA in December 2009.
Gal, along with fellow surgeon Dr. Joseph Valentino, will begin using the TORS procedure at UK Chandler Hospital next month.

Scottsdale seminars aim to improve women’s health April 28, 2010
SCOTTSDALE, AZ -- Some women don't like talking about issues that affect them below the belt, but this month that's the topic for a series of seminars put on by Scottsdale Healthcare.
As part of the seminars, the hospital is introducing a new high-tech surgical robot during a free “Below the Belt Issues for Women” seminar May 4 at Scottsdale Healthcare Thompson Peak Hospital and May 27 at Scottsdale Healthcare Shea Medical Center.
“Below the Belt Issues for Women” will be from 7-8 p.m. with check in at 6:30 p.m.
The events will feature:
• Women’s health updates – Scottsdale Healthcare OB/GYN Burt Webb, MD will discuss how women can take control of their health through diet, exercise and annual gynecologic exams. He also will discuss robotic surgery for gynecological disorders. • Surgical robot test drives – Attendees can take the controls of Scottsdale Healthcare’s daVinci surgical robot to experience its precision during minimally invasive surgery, including gynecological procedures.
Use of Robotic Surgery Enhances Precision April 28, 2010
Dr. Paul Magtibay specializes in gynecologic oncology and urogynecology. He also specializes in robotic surgical procedures. This is a particular type of laparoscopic procedure which allows minimally invasive surgery requiring only small incisions. The robot lends greater accuracy in laparoscopic dissection.
Robotic surgery allows three dimensional viewing, rather than the standard two dimensional view. Unlike other laparoscopic equipment, robotics instruments articulate which allow for greater dexterity and precision.
"Mayo Clinic Arizona focuses on the Southwest part of the United States, principally that of the Phoenix metropolitan area but we have a number of patients from the Las Vegas region, Albuquerque in New Mexico, but anywhere in the nation that we have contracts people have the opportunity to come and visit us and receive their care here."
Dr. Magtibay is the chair of the Department of Medical and Surgical Gynecology at Mayo Clinic, Arizona. He also specializes in gynecologic surgery like vaginal fistulas and vaginal reconstruction.

Surgeon experience trumps method of operation in patient outcomes for prostate surgery Dallas, TX Monday, April 26, 2010
Patients who are considering surgery for prostate cancer should be swayed more by surgeon experience than by the technique used for the actual procedure, according to a UT Southwestern Medical Center physician.
Dr. Yair Lotan, associate professor of urology, said a patient's anatomy and a surgeon's experience in performing either open surgery or robot-assisted laparoscopic surgery for prostate removal best dictates patient recovery. Dr. Lotan's editorial comment accompanies a study in the April issue of the Journal of Urology by researchers from the Department of Surgery at Memorial Sloan-Kettering Cancer Center.
The New York-based researchers evaluated the outcomes for either laparoscopic, robot-assisted prostate surgery or open surgery in 5,923 men ages 66 and older. They found no statistically significant differences in the rates of general medical or surgical complications between the two techniques. In robot-assisted cases, however, there was a correlating decrease in length of hospital stay.
"Obviously, you want a surgeon who is experienced and comfortable with the technique they use and one who has done the surgery often and with excellent patient outcomes," said Dr. Lotan. "There are many factors that influence a patient's decision to have surgery. If you go to a surgeon just because he or she is using a robot, that doesn't mean your outcomes will be significantly better compared with open surgery."
According to federal statistics, there are almost 170,000 new cases of prostate cancer diagnosed each year in the U.S. About 67,000 of these men will opt for surgical treatment, which typically involves removal of the diseased prostate, the surrounding lymph nodes and any tissue that may be cancerous.....continue reading
Tulane boasts rare surgery Posted April 24, 2010
Emad Kandil, assistant professor of surgery and chief of endocrine surgery at Tulane Medical Center is performing thyroid surgeries that are rarely performed in the United States.
The surgery leaves no visible scars and is almost painless. Because of this surgery and other technological advancements, the Tulane University Medical Center attracts surgeons who are keeping with the latest trends in medical technology. The medical center also attracts prospective medical students because of its highly regarded use of medical technology.
Last month Kandil offered a course to more than 100 surgeons from all over the world to learn about these new types of minimally invasive procedures.
“Tulane is one of few medical institutions that uses state-of-the-art, top-of-the-line medical technology to perform surgeries,” Kandil said.
With the use of robotic technology, surgeons can remove potentially deadly tissue from vital organs. Because of the accuracy and precision the equipment provides, patients leave with little to no nerve damage, tissue damage or visible scars, which is a significant change from traditional surgical techniques that caused patients pain due to the unintentional damage of nerves and other tissues as well as permanent scars.
Students from around the world apply to Tulane specifically for its use in robotic technology. Jenna Michaels, a prospective Tulane medical student, said she is excited about the latest medical technology. “I am really looking forward to attending Tulane’s medical school,” Michaels said. “Their use of the latest technology says a lot about Tulane and promises a healthier and safer future for patients.” Read more

Is robot prostate surgery best for quality of life? Posted April 22, 2010
NEW YORK (Reuters Health) - Despite the popularity of robot-assisted procedures for prostate cancer, when it comes to men's long-term quality of life, patients with earlier stage cancers generally fare better with non-surgical approaches than with surgery, according to a new study.
Researchers say the findings, reported in the Journal of Urology, offer men more information to consider when deciding on treatment.
Men with earlier stage prostate cancer have a number of treatment options, from "watchful waiting" to radiation to surgical removal of the prostate gland.When it comes to surgery, robot-assisted laparoscopic surgery has become the dominant approach in the U.S.
After hospitals invest the roughly $1.5 million for the machines, plus the costs of surgeon training and annual service contracts, they often aggressively market robotic surgery. That may include claims that it carries lower risks of long-term incontinence and impotence than traditional open surgery. Actual study data to prove that, however, are lacking.
In a new study, researchers at the Sentara Health System/Eastern Virginia Medical School in Norfolk followed 785 men...continue reading
KUKA's Lightweight Robot, LWR
Robotics -Titan's Amadeus and Kuka's LWR Set to Enhance Precision Surgery Posted April 22, 2010
With the increasing need for precision and accuracy in surgical procedures, and with administrative tasks taking their toll, hospitals round the world are turning to robotics for help.
Titan Medical Inc., which is currently developing 'Amadeus', a next generation robotic surgical system, promises to take surgery to an entirely new level. It has selected KUKA robotics Corporation, a reputed supplier of industrial robots, to supply its Lightweight Robot, LWR in short, which is to be integrated with Amadeus.
The Lightweight Robot, weighing about 15kg, is a seven-axis jointed-arm robot that can perform tasks, which require maximum precision. Its powerful touch, closely resembling the motion sequences of the human arm, makes it easy to use.
Having been tested for safety and with its high efficiency in power consumption, this robot working in conjunction with Amadeus could prove highly beneficial for Titan Medical.
Surgeons can use the robot to perform tasks that are repetitive in nature, merely by making the robot manually perform each step of the task in the required order.
Titan's Amadeus development program, which seeks to improve upon keyhole surgery, is expected to be enhanced with the integration of the lightweight robot.
Dr. Reiza Rayman, President of Titan Medical Inc., spoke highly of the LWR and said that it represented a significant advancement in medically designed robotic technology. Its speed, intelligence and accuracy were unprecedented. Rayman was confident that the LWR technology would further advance the capability of Titan's Amadeus platform. For complete story Click here
In a related news release, Titan Medical Inc. announced that it has signed an agreement with CAE Healthcare for various services related to the development of Titan's Amadeus clinical-grade robotic surgery platform. Once completed, the platform could be used, not only to perform surgery at a distance, but also to train surgeons via simulation.
Gamma Knife and Cyber knife, though termed as 'knife' actually don't function as one that cuts through. Both techniques are noninvasive modes of radiation treatment and are advantageous in their own way. The treatment therapies have their application in treatment of both cancerous and non-cancerous tumors anywhere in the body, including the brain, spine, liver, prostate, lung, pancreas and kidney.
Gamma Knife is a device used in the treatment of Brain tumors with an external beam of Gamma radiation (electromagnetic radiation of high frequency and very short wavelength), at a pre determined dose.
The size and the position of the tumor are first determined.
The patient is provided a special stiff helmet/Head frame for two reasons; one is to protect the normal cells of the brain and the other is to keep the brain in a static position when the treatment is on. This is commonly called as a stereotactic system. The procedures involving stereotactic system are generally aided by MRI (magnetic resonance imaging), by CT (computerized tomography), by angiography or X-ray techniques with the help of a position determining or referential device based on a Cartesian coordinate system.
The radiation is aimed at the tumor in the patient's brain. The treatment is highly target specific.
The patient does not sense the radiation and hence does not experience any pain.
This treatment is commonly referred to as 'robotic surgery'. It is also a kind of noninvasive radiation therapy. More than a device it is a system that by itself tracks and adjusts the treatment with the aid of software programmed for image guidance. The preparations for the surgery remain the same as in Gamma knife, the only difference being the movement of the patient is not hundred percent restricted in case of Cyber knife.
Gamma Knife Vs Cyber knife
Application - Gamma knife has its benefits mainly in Brain surgery whereas in other conditions of tumor formation, where respiration causes movement in the tumor, Cyber knife is preferred.
Treatment mode - Gamma knife makes use of multiple beams from Cobalt as the source, whereas Cyber knife makes use of a single high energy beam with X-rays as the source (more powerful than the beam extracted from Cobalt).
Accuracy - Though Gamma knife is spoken to be more accurate than Cyber knife, there is no established proof on the same.
Treatment time - The overall treatment in case of Gamma knife requires just one session after which the patient may return to his normal routine. The Cyber knife procedure requires multiple sessions each of almost an hour.
Treatment compliance - The head frame that is made use of in Gamma knife is associated with some side effects like nausea and headache because the gear is screwed into the skull for immobilization. Cyber knife is a frameless treatment, making use of a thermoplastic head mask (noninvasive and this makes the technique devoid of side effects.
Cost - Gamma knife cost of treatment is lower than the Cyber knife cost (ranging from $25000 to $50000). The investment for hospitals to establish Cyber knife is huge and hence the treatment is available with a very limited centers world over.
Trifecta Approach Important in Prostate Cancer Treatment April 20, 2010
With 3,000 Successful Surgeries and Counting, Dr. David B. Samadi, MD Aims High When It Comes to Prostate Cancer Cure
NEW YORK, NY--(Marketwire - April 20, 2010) - Three is a very important number to Dr. David Samadi, Chief of Robotics and Minimally Invasive Surgery at The Mount Sinai Medical Center.

Meet Dr Robot By Fred Tasker, Tuesday, April 20, 2010
Three robots - no waiting. It could be the slogan of South Miami Hospital, where 19 surgeons will perform more than 1,000 robotic surgeries this year. Since its program began in 2007, the hospital has become one of the world's busiest centers for surgeries using the robots, called da Vinci Surgical Systems.
It ranks fifth in the combined total of gynecologic, prostate, thoracic, bariatric, colorectal and heart surgeries performed with robots.
"This is the future," says Wayne Brackin, chief operating officer of Baptist Health South Florida, the hospital's parent company, who helped set South Miami's course when he was chief executive there. "We don't want to be left behind."
Other hospitals are busy too. Surgical robots won US Food and Drug Administration approval in 2000, and there are now 1,395 of them in 860 hospitals worldwide, performing more than 200,000 operations a year.
Advocates say robots do surgery with greater precision, reducing pain and blood loss, shortening hospital stays and getting patients back to work more quickly.
But critics say that despite its meteoric growth, robotic surgery lacks an adequate body of solid scientific studies demonstrating that it is better than traditional open surgery or regular laparoscopy.
To a layman, the surgical robot is dazzling. The human surgeon sits at a computer console peering into a monitor that gives him or her a view inside the patient's body that is full-color, three-dimensional and magnified 10 times. Across the room, the robot's four massive arms wield delicate surgical instruments inside the patient, carrying out the surgeon's instructions with space-age precision. Read more
Emerging Robotic Technologies to Transform the Role of the Surgeon April 19, 2010
World renowned experts on robotics and virtual reality shared their perspectives on how advancements in technology are transforming the operating room from an environment dominated by human interactions to a space where the surgeon is a steward of robotic and virtual technologies that will improve surgical planning and outcomes.
In a symposium presented at the Society of American Gastrointestinal and Endoscopic Surgeons (SAGES) 12th World Congress of Endoscopic Surgery, hosted by SAGES and the Canadian Association of General Surgeons, National Harbor, Maryland, Mehran Anvari, MD, professor of surgery at McMaster University in Hamilton, Ontario, Canada, and Jacques Marescaux, MD, chairman, Department of Digestive and Endocrine Surgery, University Hospital of Strasbourg, France, led a panel of experts in discussing innovations that are likely to affect surgical practice in the near future.
Dr Anvari emphasized that “new technologies from information age discoveries are driving basic approaches in virtually all aspects of healthcare innovation.”. Read more
Professor Jens Rassweiler
The future of robotics April 19, 2010
At yesterday’s Meet the Expert session at the 25th Annual EAU Congress, Professor Jens Rassweiler, Chairman of the EAU Section of Uro-Technology, talked to journalists about the importance of robotics in future laparoscopic surgery.
No new developments in EAU guidelines concerning robotic surgery are expected, since without a Phase 3 trial it is difficult to compare robotic laparoscopic prostatectomy to open prostatectomy. It is, however, included as an alternative in the guidelines.
“About 50% of our patients are currently undergoing robotic surgery and the number is increasing. It took me some time to get used to the 3D vision and the higher magnification”, says Rassweiler.
The lack of tactile feedback does not seem to be a problem; only if tissue needs to be pushed aside, but the vision helps. “There are new robots with tactile feedback, which are definitely improvements”, according to Prof. Rassweiler.
Companies with new technologies tend to focus on the industry market in view of the patent issues in the medical market. This interferes with the development of new technologies. “Telesurgery can however not be patented so this will be solved in the end I am sure”, says Prof. Rassweiler....continue reading
AIIMS robot performs rare cancer surgery
By IANS, April 19, 2010
New Delhi: In a rare cancer surgery, doctors at the All India Institute of Medical Sciences (AIIMS) removed seven body parts, including urinary bladder and ovaries, from a 50-year-old patient with assistance from a robot.
P.N. Dogra, head of the department of urology, performed the robot-assisted "anterior pelvic exenteration" on a woman suffering from cancer of urethra and urinary bladder.
"In this operation the urinary bladder, uterus, fallopian tubes, ovaries, anterior vaginal wall, urethra and pelvic lymph nodes were removed," Y.K. Gupta, a senior professor and chief spokesman of AIIMS, said.
"This was done for the first time in the country. It was a challenging surgery and required high-tech surgical skills," Gupta claimed.
Gupta said the AIIMS has initiated a drive to use the robot so that maximum number of patients can benefit.

Robotic Assistance for Minimally Invasive Surgical Techniques
Posted: April 19, 2010
Minimally invasive surgical (MIS) techniques continually develop towards reducing the invasiveness of many surgical procedures. While surgeries performed using MIS techniques offer significant patient advantages, the procedures are surgically challenging. The surgeon’s ability to visualize and manipulate the surgical target is limited by working through very small incisions. Robotic surgical tools have emerged as a way to improve dexterity and vision in minimally invasive procedures, but many of these systems are limited by their bulky size, high cost and limited dexterity.
A novel tool positioning robot has been proposed to develop a new paradigm for MIS surgery. The robot has been developed using a spherical bevel-geared mechanism to achieve the dexterous workspace without the drawbacks of bulky robot arms. Kinematic optimization based on a genetic algorithm has been performed to further improve the mechanism configuration. The robot can be teleoperated by using a master control system with joystick-like manipulators. In addition, kinematics and dynamics have been developed as a foundation for intuitive motion control. Clinical experiments indicate that the robot can provide the surgeon with a stable and remotely adjustable platform for holding and positioning of tools for MIS. The compactness of the system and its telesurgery capabilities will enable the benefits of robotic surgery to be reaped by a much larger patient population.
The complete elimination of external incisions through natural orifice access is potentially our next step in reducing patient trauma. Miniature in vivo robots are being developed that are completely inserted into the peritoneal cavity for natural orifice procedures. All these surgical robotics paradigms can significantly advance the capabilities and the perception of robots for surgical care. Article from Latest Wilkes News Archives

Online Medicine - The Doctor is IN April 14, 2010
Technology has changed our lives drastically over the past 20 years. Just about everything can be done online these days from shopping, dating and working to even consulting a doctor thousands of miles away.
One of the fastest growing online medical Internet platforms is Myca which allows doctor-patient consultation remotely, by phone, email, instant messaging or even video conferencing. It also enables patients to schedule doctor's appointments online. Myca is barely two years old but has gained quite a following. In the US, the Myca Platform goes under the Hello Health trademark. Welcome to today's e-practice. The doctors call themselves "your friendly 21st doctors in the neighborhood".
Telemedicine / virtual medicine encompasses any digital form (e-mail, fax, telephone, video conferencing, etc.) of bringing together patients and physicians. However, with the arrival of less expensive broad-band internet access and digital imaging, telemedicine currently refers to interactive, full motion, two-way video and audio over high-speed data networks. Patients and physicians are connected through secure web camera video that also allows rapid assessment of the patient.
Leading British surgeon creates micro-robots which remove diseased organs through patients' mouths April 14, 2010
Professor Lord Darzi, a leading British surgeon is creating a series of tiny robots which remove diseased organs by dragging them out through the patient's mouth. Professor Lord Darzi, the keyhole surgery pioneer, believes the micro-robots - which move like cockroaches - could lead to more scar-free surgery. The former Labour health minister says he hopes that doctors will eventually be able to cut out diseased organs and tumours using lasers held in the mouths of his robotic insects.
Hospital time and recovery time is drastically reduced because organs can be withdrawn orally and there are no external wounds that need time to heal. 'The benefits are very obvious, Lord Darzi said - less pain, which means earlier mobility, and quicker return to work.'
Scientists have studied both cockroaches and earthworms in their search for the most suitable model to base their tiny robots on. Lord Darzi used cockroaches as his model for the new devices because they are easily able to enter unstable places. He has already experimented with the removal of organs from the mouths of pigs. But now he has revealed for the first time that he is hoping to introduce the idea into the treatment of human patients.......continue reading
Physicians watch a demonstration of robotic surgery using 3-D technology on Sunday, during the World Robotic Symposium 2010 at Disney's Yacht and Beach Club
3-D robotic surgery demonstrated at Disney April 12, 2010
For a time on Sunday morning, the meeting room in the Walt Disney World Yacht and Beach Club looked like one of those 1950s movie theaters with the audience wearing cardboard 3-D glasses.
But instead of cartoonish characters on the screen, it was robotic pincers delicately snipping at the internal organs of a woman having a hysterectomy. The combination of medical robotics and 3-D technology allows surgeons to burrow beneath the skin to perform operations that once required opening up a patient.
"The reason for doing robotic surgery is that it's less invasive and more precise," said Dr. Vipul Patel, who organized the World Robotic Symposium attended by more than 1,000 surgeons from around the world.
Patel, who has performed more than 3,500 robotic procedures at Florida Hospital, uses a $1.5 million robotic console equipped with a magnified 3-D view of the body's interior. The combination of robotics and 3-D imagery allows Patel to perform prostate removal surgeries that take less time, allow the patient to heal faster and reduce the risks of bleeding and infections....continue reading
Study Shows Significant Advantages of Computer-Assisted Robotic Total Knee Replacement April 12, 2010
Newswise — A study of 1,000 consecutive Computer-Assisted Robotic Total Knee Replacements performed over a five year period at Mercy Medical Center in Rockville Centre, NY demonstrates that the computer-assisted procedures result in far better leg alignment, much less likelihood of complicating infection, and a far lower early failure rate than surgeries performed using conventional techniques.
The key factor in successful total knee replacement is precise placement of the artificial joint so that the center of the patient’s hip and knee lines up within three degrees of the patient’s ankle. Using conventional techniques, the best surgeons achieve alignment within three degrees 50 to 80 percent of the time. At Mercy Medical Center, alignment within three degrees was achieved in all (100%) of the 1,000 computer-assisted robotic procedures performed between February, 2005 and January, 2010. Final post-surgical alignment averaged just under one degree (0.8).
Jan Koenig, MD, Director of Orthopedic Surgery at Mercy Medical Center, presented the findings on March 10, 2010 to a group of over 200 international orthopedic surgeons at the Annual Meeting of the American Academy of Orthopaedic Surgeons (AAOS) in New Orleans. His presentation, The Evolution of Computer-Assisted Total Knee Replacement (CAS-TKR) Past, Present and Future, was a featured part of Medacta Orthopedics Scientific presentations.
At the present time, Mercy Medical Center has the longest consecutive experience with computer assisted robotic total knee replacement in the country, and is the only hospital in New York State routinely performing computer-assisted robotic total knee replacements. The procedures are performed using a system called the PiGalileoTM, developed and manufactured in Switzerland by PLUS Orthopedics.
Qatar Robotic Surgery Centre starts training courses April 12, 2010 From QatarsHub.com
Qatar Robotic Surgery Centre (QRSC) has organized the first robotic surgery training in collaboration with the Gulf Heart Association, in attendance of 12 cardiac surgeons from across the GCC member states. This first training marks the operational launch of Qatar Robotic Surgery Centre, which is initiated by Qatar Science and Technology Park and will be officially inaugurated at the end of 2010.
Concurrently several collaborative technology development activities in medical robotics will be initiated. With also clinical application of robotic surgery well on track in Hamad Hospital, Qatar is clearly well positioned to lead the way in surgical robotics in the near future. The concept of Qatar Robotic Surgery Centre is unique, as it emphasizes on advanced simulation training and cross-fertilization between its training and technology development activities.
During hands-on sessions the cardiac surgeons performed coronary artery bypass surgery with a real surgical robot on a beating silicone model of a heart in a simulated Operating Room. The Clever use of advanced simulation methodologies allows training surgeons up to a higher level before their skills are perfected on animals and during proctored cases on real patients.
However, the centre seeks to become a connection point for experts with high level in robotic surgery. It also works through the integrated interaction and cooperation with the interested local and international experts to upgrade the State of Qatar to become a global center for robotic surgery. (QNA)

Prostate cancer surgery more costly for obese men Wed, Apr 7 2010, by Amy Norton
NEW YORK (Reuters Health) - Being obese may increase the cost of surgery for men with prostate cancer -- at least the more traditional forms of the procedure, a new study suggests.
Researchers found that among 629 prostate cancer patients at their center who had a radical prostatectomy -- surgical removal of the prostate gland -- obese men generally incurred greater costs. The difference, the study found, came from higher costs for anesthesia and other services in the operating room. However, while obesity was related to greater expenses from both traditional "open" surgery and minimally invasive laparoscopic, or "keyhole" surgery, it did not affect the price tag of robot-assisted laparoscopic surgery -- a technique that, over the past decade, has become the predominate approach to prostate removal in U.S. hospitals.
Among patients who underwent traditional surgery, performed through a long abdominal incision, the typical cost for obese men was $4,885. That compared with $4,377 for all other men. The pattern was similar when it came to traditional laparoscopic, "keyhole" surgery, the typical cost was $5,703 for obese men and $5,347 for their non-obese counterparts. In contrast, weight did not appear to sway the costs of robot-assisted laparoscopic surgery, in which a surgeon sits at a computer console, controlling robotic "arms" that hold the surgical instruments. The price tag for robotic surgery was $6,761 for obese men and $6,745 for thinner men, according to findings published in the urology medical journal BJU International.....For complete story Click here

About Catherine Mohr: Posted April 3, 2010
At age 27 she had what most engineers would consider a dream job: product engineering manager at AeroVironment, a boutique firm in Monrovia, Calif., that designs and builds some of the world’s most advanced land and air vehicles. She’d helped build cars for Switzerland’s Tour de Sol and Australia’s first World Solar Challenge, worked on power trains for hybrid cars, supervised construction of a hybrid off-road military reconnaissance vehicle, and started a laboratory to develop fuel-cell systems for aircraft designed to stay aloft for months at a time.
”It was a glorified toy factory,” Mohr recalls. ”It was just the kind of thing I wanted to be doing.”
But in the late 1990s, she started to tire of making incredibly cool vehicles in lots of one or two. "We’d been working with each one of the Big Three U.S. car companies for years. We had built electric prototypes, hybrid prototypes.” But the U.S. car companies weren’t commercializing these designs.
She was still pondering the idea of a career change when she talked to a surgeon friend about her situation. The friend invited her to come to Massachusetts General Hospital to watch some surgeries involving experimental medical devices.
She observed the test of a new device, an aortic stent that could be inserted through the blood vessels like a catheter. The attempt failed, and the surgeons had to revert to traditional open-heart surgery. But that failure was a revelation to Mohr.
”It seemed to me that if the engineers had been as intimately familiar with the body as the surgeons were, there would have been a better chance that the stent would have worked,” Mohr says. She listened to the engineers and the surgeons in the operating room. ”They just didn’t speak each others’ languages,” she says, noting that the surgeons would propose fantastical solutions that involved breaking the laws of physics, and the engineers would try to bring those solutions into the realm of reality without fully understanding the fundamental problem the device was meant to solve.

Robotic-Assisted Surgery Gets Boost from New Training Simulator April 2, 2010
Robotic-assisted surgeries can be good for patients and good for the hospital's bottom line, but a hang up for medical staffs is that it's not easy to train surgeons on these systems.
That's where the new Robotic Surgical Simulator, or RoSS, comes in. Designed by researchers from the University at Buffalo and Roswell Park Cancer Institute (RPCI), RoSS uses simulation technology borrowed from the airline industry with the goal of providing a relatively inexpensive and quick training solution for today's surgeons.
RoSS was not designed specifically for da Vinci surgical training, one of the most popular systems on the market. Rather, it teaches the techniques employed by all robotic surgical systems.
Credentials committee will have to wait a little while before reviewing the competency data from RoSS-trained surgeons. Orders for the finished RoSS modules are scheduled to be delivered in January 2011.
Although the makers of RoSS came from varied backgrounds, the training problems facing robotics-assisted surgeons were clear to all.
"Robotic-assisted surgery systems are relatively new and right now there's no systematic way of training surgeons for the robot other than going to the animal lab, for instance, or shadowing, where a doctor gets a chance to sit with the experienced surgeon," says Thenkurussi ("Kesh") Kesavadas, PhD, professor of mechanical and aerospace engineering at the University of Buffalo and head of its Virtual Reality Lab.
Even the technique of shadowing another surgeon can have its disadvantages, especially when it comes to training on the popular da Vinci Surgical System.
"The problem right now is it's a $2 million robot, it's in the OR, the administration wants you to do more cases rather than training people, and a lot of surgeons feel intimidated by it," says Khurshid A. Guru, MD, director of the Center for Robotic Surgery and attending surgeon in RPCI's Department of Urology. "You need to have a simulation-based curriculum." How does this simulation training device work?
Hospital robot will handle some procedures Posted April 2, 2010
MIDDLETOWN, OH — Atrium Medical Center is the latest local hospital to begin using a da Vinci robot for certain procedures.
The hospital, part of Premier Health Partners, plans to start using the robot for urologic procedures, such as prostatectomies, in early April, according to a news release.
Atrium Medical Center Foundation is raising $500,000 to fund a fourth of the robot’s purchase price through its “Imagine a Cure” campaign, which is meant to expand and enhance cancer care at the medical center. Atrium Auxiliary Middletown made the lead gift of $100,000. Pat and Karen Piccioni of Middletown are co-chairing the campaign.....read more
Robot soon able to operate inside MRI scanners April 1, 2010
The MIRA Institute for Biomedical Technology and Technical Medicine of the University of Twente has been awarded a €1.9 million grant from the Dutch government's 'Pieken in de Delta' regional economic development scheme. With the grant it will develop technology to enable robot-assisted operations inside MRI scanners. The researchers will initially develop the technology for the diagnosis and treatment of prostate cancer, but the technology will be applicable for a variety of minimally invasive surgical procedures. MIRA will be working on the project in partnership with the Radboud University Nijmegen Medical Centre, Demcon, Siemens and Xivent Medical.
New developments in medical technology mean that medical treatments are becoming increasingly effective and less invasive. Within the realm of 'minimally invasive surgery', operations will be carried out through a natural body opening or a small incision, where the clinician will use extremely small, robotically-controlled instruments. The advantage of this type of surgery is that it reduces patient trauma and enables quicker recovery time.
Because clinicians cannot directly see the area being operated on during minimally invasive surgery, they often rely on medical imaging techniques. One of the best known of these is Magnetic Resonance Imaging (MRI). This method would be highly suitable for use in combination with certain minimally invasive surgeries were it not for the fact that MRI scanners use extremely strong magnets. As a result traditional instrumentation made of ferromagnetic materials cannot be used in the scanner. Further, due interference with the electromagnetic field, conventional electronic equipment is not suitable....read more
Options exist in prostate treatment Posted April 2, 2010
Prostate cancer strikes, on average, one in six men today -- but it's almost certain those statistics are going to get worse, not better, experts say.
"Doctors are saying it will reach one in four [men] within five to 10 years," said Steve Jones, president and chief executive officer of Prostate Cancer Canada. "It is definitely on the rise."
Not only are there now millions of boomers now in their 50s and 60s -- the age at which significant numbers of prostate cancers begin appearing in a population -- our high-fat Western diets appear to be contributing to the disease.
Prostate cancer is not a one-size-fits-all disease. "Prostate cancer is an interesting disease because it comes in many different shapes and sizes, if you will. It is a creature of many appearances," said Larry Goldenberg, professor of urology at the University of British Columbia and founding director of the Prostate Centre at Vancouver General Hospital. The cancer can be so slow that it will never threaten the health of the individual, or it can be a critical, life-threatening affliction requiring immediate attention.
The two traditional ways of dealing with prostate cancer have been either radical surgery removing the prostate, or radiation. What has changed is how those surgeries are carried out, and newer treatments -- some of them experimental -- are being applied.
"On the therapeutic side, robotic surgery, different forms of radiation and all these other alternative forms of treatment" are the hot topics in prostate cancer treatment today, Goldenberg said....continue reading
