Intuitive Surgical's da Vinci Console Controls
Traditional Laparoscopic Surgery compared to da Vinci Robotic Surgery
The technology used in Intuitive Surgical's da Vinci surgical robot is made to allow surgeons to operate through the small ports used in non-invasive surgery however with the same direct approach learned in open surgery and similar or even better range of motion.
This is as opposed to traditional laparoscopic surgery, in which the surgeon must move the instrument handles within the other direction because the instrument tips - left means right and right means left. Many surgeons describe this approach to be counter-intuitive. Instead, when the da Vinci surgeon moves the console controls clockwise, the tiny wristed instruments inside the patient twist clockwise too.
Surgeons state that they benefit from the user interface design, which is very much like the experience of performing open surgery. Their patients benefit from a non-invasive approach that provides better precision, visualization and control as compared to conventional laparoscopy.
Health Tech Trends : Roles in Robotic Surgery featuring Dr. David Samadi
The Institute for Health Technology Transformation (iHT2) commissioned this piece of "Roles in Robotic Surgery". It features Intuitive Surgical's da Vinci Surgical Robotic System and Dr. David Samadi of Mount Sinai School of Medicine offering his thoughts on the future of robotic surgery, specifically robotic prostatectomy.
The lack of crossover between industrial robotics and medicine,
particularly surgery, is at an end.
Surgical robots have entered the field in force. Robotic telesurgical machines have already been used to perform transcontinental cholecystectomy. Voice-activated robotic arms routinely maneuver endoscopic cameras, and complex master slave robotic systems are currently FDA approved, marketed, and used for a variety of procedures. It remains to be seen, however, if history will look on the development of robotic surgery as a profound paradigm shift or as a bump in the road on the way to something even more important.
Paradigm shift or not, the origin of surgical robotics is rooted in the strengths and weaknesses of its predecessors. Minimally invasive surgery began in 1987 with the first laparoscopic cholecystectomy. Since then, the list of procedures performed laparoscopically has grown at a pace consistent with improvements in technology and the technical skill of surgeons. The advantages of minimally invasive surgery are very popular among surgeons, patients, and insurance companies. Incisions are smaller, the risk of infection is less, hospital stays are shorter, if necessary at all, and convalescence is significantly reduced. Many studies have shown that laparoscopic procedures result in decreased hospital stays, a quicker return to the workforce, decreased pain, better cosmesis, and better postoperative immune function.
As attractive as minimally invasive surgery is, there are several limitations. Some of the more prominent limitations involve the technical and mechanical nature of the equipment. Inherent in current laparoscopic equipment is a loss of haptic feedback (force and tactile), natural hand-eye coordination, and dexterity. Moving the laparoscopic instruments while watching a 2-dimensional video monitor is somewhat counterintuitive. One must move the instrument in the opposite direction from the desired target on the monitor to interact with the site of interest. Hand-eye coordination is therefore compromised. Some refer to this as the fulcrum effect. Current instruments have restricted degrees of motion; most have 4 degrees of motion, whereas the human wrist and hand have 7 degrees of motion. There is also a decreased sense of touch that makes tissue manipulation more heavily dependent on visualization. Finally, physiologic tremors in the surgeon are readily transmitted through the length of rigid instruments. These limitations make more delicate dissections and anastomoses difficult if not impossible. The motivation to develop surgical robots is rooted in the desire to overcome the limitations of current laparoscopic technologies and to expand the benefits of minimally invasive surgery.
From their inception, surgical robots have been envisioned to extend the capabilities of human surgeons beyond the limits of conventional laparoscopy. The history of robotics in surgery begins with the Puma 560, a robot used in 1985 by Kwoh et al to perform neurosurgical biopsies with greater precision. Three years later, Davies et al performed a transurethral resection of the prostate using the Puma 560 This system eventually led to the development of PROBOT, a robot designed specifically for transurethral resection of the prostate. While PROBOT was being developed, Integrated Surgical Supplies Ltd. of Sacramento, CA, was developing ROBODOC, a robotic system designed to machine the femur with greater precision in hip replacement surgeries. ROBODOC was the first surgical robot approved by the FDA.
Also in the mid-to-late 1980s a group of researchers at the National Air and Space Administration (NASA) Ames Research Center working on virtual reality became interested in using this information to develop telepresence surgery. This concept of telesurgery became one of the main driving forces behind the development of surgical robots. In the early 1990s, several of the scientists from the NASA-Ames team joined the Stanford Research Institute (SRI). Working with SRI's other robotocists and virtual reality experts, these scientists developed a dexterous telemanipulator for hand surgery. One of their main design goals was to give the surgeon the sense of operating directly on the patient rather than from across the room. While these robots were being developed, general surgeons and endoscopists joined the development team and realized the potential these systems had in ameliorating the limitations of conventional laparoscopic surgery.
The US Army noticed the work of SRI, and it became interested in the possibility of decreasing wartime mortality by "bringing the surgeon to the wounded soldier-through telepresence." With funding from the US Army, a system was devised whereby a wounded soldier could be loaded into a vehicle with robotic surgical equipment and be operated on remotely by a surgeon at a nearby Mobile Advanced Surgical Hospital (MASH). This system, it was hoped, would decrease wartime mortality by preventing wounded soldiers from exsanguinating before they reached the hospital. This system has been successfully demonstrated on animal models but has not yet been tested or implemented for actual battlefield casualty care.
Several of the surgeons and engineers working on surgical robotic systems for the Army eventually formed commercial ventures that lead to the introduction of robotics to the civilian surgical community. Notably, Computer Motion, Inc. of Santa Barbara, CA, used seed money provided by the Army to develop the Automated Endoscopic System for Optimal Positioning (AESOP), a robotic arm controlled by the surgeon voice commands to manipulate an endoscopic camera.
Shortly after AESOP was marketed, Integrated Surgical Systems (now Intuitive Surgical) of Mountain View, CA, licensed the SRI Green Telepresence Surgery system. This system underwent extensive redesign and was reintroduced as the Da Vinci surgical system. Within a year, Computer Motion put the Zeus system into production.
• The world's first surgical robot was the "Arthrobot", which was developed and used for the first time in Vancouver, BC, Canada in 1983. The robot was developed by a team led by Dr. James McEwen and Geof Auchinlek, in collaboration with orthopaedic surgeon, Dr. Brian Day. National Geographic produced a movie on robotics which featured the Arthrobot. In related projects at that time, other medical robots were developed, including a robotic arm that performed eye surgery and another that acted as an operating assistant, and handed the surgeon instruments in response to voice commands.
• In1985 a robot, the PUMA 560, was used to place a needle for a brain biopsy using CT guidance.
• In1992, the ROBODOC from Integrated Surgical Systems was introduced to mill out precise fittings in the femur for hip replacement.
Further development of robotic systems was carried out by Intuitive Surgical with the introduction of the da Vinci Surgical System and Computer Motion with the AESOP and the ZEUS robotic surgical systems. Intuitive Surgical bought Computer Motion in 2003; ZEUS is no longer being actively marketed.
The da Vinci Surgical System comprises three components: a surgeon’s console, a patient-side robotic cart with 4 arms manipulated by the surgeon (one to control the camera and three to manipulate instruments), and a high-definition 3D vision system.
Articulating surgical instruments are mounted on the robotic arms which are introduced into the body through cannulas. The surgeon’s hand movements are scaled and filtered to eliminate hand tremor then translated into micro-movements of the proprietary instruments.The camera used in the system provides a true stereoscopic picture transmitted to a surgeon's console.
The da Vinci System is FDA cleared for a variety of surgical procedures including surgery for prostate cancer, hysterectomy and mitral valve repair, and is used in more than 800 hospitals in the Americas and Europe. The da Vinci System was used in 48,000 procedures in 2006 and sells for about $1.2 million. For more information Click here

Robotic-Assisted Surgery: 'Pushing the Boundaries of Medicine'
Catherine Mohr talks about Surgical Robots
"New robotically assisted surgery methods and devices are helping us push the boundaries of medicine," says Catherine who left her lucrative career as an engineer to complete medical school in order to better learn and apply her skills in surgical robotics and medical device development. "By focusing on fewer incisions, more precision and more versatility with these procedures and devices, we are making surgery safer and more efficient for patients," she says.
For instance, the combination of precision and minimal invasion allow these robots, under the guidance of human surgeons, to sew a blood vessel onto a beating heart without the necessity of surgeons opening the entire chest cavity....read more
Robotics-assisted surgery has become enormously popular, with physicians around the world performing 1.5 million procedures — from hysterectomies to heart valve repairs — in 2011.
“But myths and misconceptions about robots in the operating room still abound,” says physician Dr. Keith Chisholm, MD, a board certified general surgeon on staff at Medical Center Trinity and Florida Hospital North Pinellas.
“One is that the robot performs the surgery,” says Dr. Chisholm. “Technically, it’s not a robot because it can’t perform surgery without someone controlling it — it’s actually computer-assisted surgery. The surgeon guides all of the movements using finger-manipulated controls.
”He and other robotics surgeons use the da Vinci Surgical System, which the U.S. Food and Drug Administration approved for minimally invasive surgeries in 2000. Nine years later, the da Vinci was being used in 80 percent of surgeries to remove cancerous prostates, according to its maker, Intuitive Surgical Inc.
“The benefits of robotics-assisted surgery are numerous,” says Dr. Chisholm, who performs several different procedures using da Vinci and became the first Pinellas-Pasco physician to use it for a single-incision cholecystectomy (gall bladder removal).
“The robotic arms hold miniaturized surgical instruments, so we can get in through very small incisions,” he says. “That means there’s less chance of infection, less pain, much less scarring and a quicker recovery time.
“Because the arms have ‘wrists’ that can rotate more than 360 degrees, we have far more maneuverability than we do with laparoscopic surgery, and we can get into hard-to-reach areas.“One of the robotic arms holds a magnified 3D high-definition camera, which gives us a much better view of the surgical site than we would have with just our own two eyes,” he said.
In a 2013 FDA survey, surgeons experienced with da Vinci said their patients have less bleeding, fewer complications, much quicker recovery times and less time in the hospital — 24 hours on average. Interestingly, those who used da Vinci to remove advanced cancer in the tonsils region of the throat said half of their patients were able to avoid chemotherapy.
What are some other myths and misconceptions?
• Myth: Robotics-assisted surgery costs much more than traditional surgery.
A study by University of Pennsylvania health economist Andrew J. Epstein published in July 2013 in JAMA Surgery found that half of the minimally invasive procedures reviewed, including robotics-assisted and laparoscopic surgeries, cost insurance providers less than the same surgeries performed in the traditional manner. Four of the six minimally invasive surgeries also resulted in fewer lost work days — sometimes several weeks fewer.
“The robotics technology is expensive and the whole surgical team has to be trained, which can add to the cost,” says Dr. Chisholm. “But there’s also a tremendous savings compared with traditional surgery because the patient is out of the hospital more quickly and there are fewer complications.”
• Myth: Robotics-assisted surgery is riskier than traditional surgeries.
Any surgery has certain risks, but in many ways, robotics-assisted surgeries have fewer overall.
“Many times, the robotics-assisted procedures can be done much more quickly, so there’s less risk simply because the duration of the procedure is shorter,” Dr. Chisholm says. “You also have smaller incisions, less bleeding, etc. that reduce the risks.”
Robotic surgery is not performed by a Data type character from Star Trek. Rather, robotic surgery puts a computer between the surgeon and the surgical tools operating on the patient. Robotic surgery incorporates the latest advances in robotics, computing, and medical imaging. In the past few years, robotic surgery has made newspaper headlines and enjoyed a rapid rise in popularity.
According to a 2005 BusinessWeek article, about 20,000 procedures were performed using robotic surgery in 2004, compared to just 1,500 procedures in 2000.
Robotic surgery falls into the broader field of minimally invasive surgery (MIS). MIS, also known as endoscopic surgery or keyhole surgery, was pioneered in 1987.
Endoscopic surgery uses small incisions and devices on the end of tubes, along with a camera to perform the surgery. But endoscopic surgery still requires that a surgeon manipulate those tools directly.
Robotic surgery takes the next step, which is to attach those tools to a computer and do it all remotely. With robotic surgical systems, also called computer-assisted surgery, surgeons don't move endoscopic instruments directly with their hands. Instead, surgeons sit at a console several feet from the operating table and use joysticks similar to those used in video games.
They perform surgical tasks by guiding the movement of the robotic arms in a process known as tele-manipulation. The da Vinci Robotic Surgery System was the first robotic system approved by the Food and Drug Administration (FDA) for assisting surgery.
Robots have superhuman capabilities that make surgery easier. For instance, they don't tire. Robotic arms don't have a tremor, so they can remain steady at all times and robotic wrists make it easier for surgeons to manipulate tissue and work from all kinds of angles.
The FDA, which must approve all such devices, says robotic surgical machines have a number of other advantages as well:
• Robotic surgical systems can also improve depth perception, giving surgeons three-dimensional vision, compared with the two-dimensional vision they would normally get with normal endoscopic procedures.
• The surgical field can be magnified so that millimeter-sized veins appear as big as pencils.
• Compared with the long instruments used in endoscopy, robotic surgical systems use smaller instruments that provide increased range of motion. This can be very helpful when operating on children.
• Robotics also offers motion scaling, which means that a surgeon's gross hand movements can be reduced to fine movements, allowing for accuracy in tight spaces. For example, with motion scaling, one inch of movement by the surgeon results in a quarter-inch movement by the robotic surgical instruments.
There are also advantages for the patient. The FDA says that robotic surgery can mean less time in the hospital along with other positives such as:
less pain and scarring
less risk of infection
less blood loss and fewer transfusions
quicker return to normal activities
The FDA say there may be times when the surgeon will begin a surgical procedure with the robot and then for one reason or another have to abandon it and do the surgery using traditional methods.
If you or a loved one has been diagnosed with a condition that may require surgery, you owe it to yourself to learn about all of your medical options, including the most effective, least invasive surgical treatments available.
The da Vinci® Surgical System provides surgeons with an alternative to both traditional open surgery and conventional laparoscopy, putting a surgeon's hands at the controls of a state-of-the-art robotic platform. The da Vinci System enables surgeons to perform even the most complex and delicate procedures through very small incisions with unmatched precision.
On this site we will introduce you to not only the daVinci® Surgical System(s) and all it's procedures available but many other Medical Robotics Systems and their procedures as well.
the doctor sits at a computer console, either in or outside the operating room, using the surgical robot to accomplish what it once took a crowd of people to perform.
How Robotic Surgery Will Work
Robotic surgery is the use of robots in performing surgery. Three major advances aided by surgical robots have been remote surgery, minimally invasive surgery and unmanned surgery. Major advantages of robotic surgery are precision, miniaturization, smaller incisions, decreased blood loss, less pain, and quicker healing time. Further advantages are articulation beyond normal manipulation and three-dimensional magnification.
In today's operating rooms, you'll find two or three surgeons, an anesthesiologist and several nurses, all needed for even the simplest of surgeries. Most surgeries require nearly a dozen people in the room.
As with all automation, surgical robots will eventually eliminate the need for some personnel. Taking a glimpse into the future, surgery may require only one surgeon, an anesthesiologist and one or two nurses. In this nearly empty operating room, the doctor sits at a computer console, either in or outside the operating room, using the surgical robot to accomplish what it once took a crowd of people to perform.
The use of a computer console to perform operations from a distance opens up the idea of telesurgery, which would involve a doctor performing delicate surgery miles away from the patient. If the doctor doesn't have to stand over the patient to perform the surgery, and can control the robotic arms from a computer station just a few feet away from the patient, the next step would be performing surgery from locations that are even farther away. If it were possible to use the computer console to move the robotic arms in real-time, then it would be possible for a doctor in California to operate on a patient in New York.
A major obstacle in telesurgery has been latency -- the time delay between the doctor moving his or her hands to the robotic arms responding to those movements. Currently, the doctor must be in the room with the patient for robotic systems to react instantly to the doctor's hand movements.
Having fewer personnel in the operating room and allowing doctors the ability to operate on a patient long-distance could lower the cost of health care in the long term. In addition to cost efficiency, robotic surgery has several other advantages over conventional surgery, including enhanced precision and reduced trauma to the patient. For instance, traditional heart bypass surgery requires that the patient's chest be "cracked" open by way of a 1-foot (30.48-cm) long incision. However, with the da Vinci system, it's possible to operate on the heart by making three or four small incisions in the chest, each only about 1 centimeter in length. Because the surgeon would make these smaller incisions instead of one long one down the length of the chest, the patient would experience less pain, trauma and bleeding, which means a faster recovery.
Robotic assistants can also decrease the fatigue that doctors experience during surgeries that can last several hours. Surgeons can become exhausted during those long surgeries, and can experience hand tremors as a result. Even the steadiest of human hands cannot match those of a surgical robot. Engineers program robotic surgery systems to compensate for tremors, so if the doctor's hand shakes the computer ignores it and keeps the mechanical arm steady.
SpineAssist; by Mazor Robotics
B efore the introduction of the Renaissance™ by Mazor Robotics there was another robotic device used for spinal surgery called the SpineAssist made by, then known as, Mazor Surgical Technologies.
SpineAssist was a revolutionary system based on miniature robotic technology specially designed for spine surgery to allow optimal precision and safety while conducting spine surgery procedures......
Here is how it worked:
The Product SpineAssist enables surgeons to accurately place implants with reduced radiation exposure during surgery.
The system consists of a miniature device that mounts above the patient’s spine, and a workstation running advanced surgical planning software.
SpineAssist’s software allows surgeons to perform 3D, CT- based preoperative planning on a personal computer at their own convenience prior to surgery.
Using a virtual catalogue of surgical implants, surgeons can view and position implants within each vertebra or disc on three planes: AP, lateral and axial. A special feature in the software is used to review the planning slice by slice in sequence.
The software supports a range of measurements including Cobb angle, lordosis and kyphosis. The surgeon can view a simulation of the correction they are planning, which is especially useful in deformity and scoliosis cases. The software also calculates rod length and curvature.
The SpineAssist workstation connects to a fluoroscopic C-Arm and performs automatic CT-to-fluoroscopy image registration based upon 2 fluoroscopic images. The workstation is used to control the precise motion of the miniature device to the preplanned position.
Miniature Device & Platforms
SpineAssist includes a miniature robotic device and is the size and shape of a soda can.
The miniature device is secured on one of the following platforms: Hover-T™ for minimally invasive, percutaneous procedures or 3+ level cases Clamp and Bridge for open procedures and scoliosis/deformity cases Bed Mount for VCF, biopsy and single level approaches Bilateral Bed Mount Hover T for Cervical and GO-LIF cases.
Each platform provides rigid stability between the patient and the SpineAssist device.
The SpineAssist software for image processing and pre-surgical planning
Accuracy in implant placement is very important in spinal surgery since most procedures are performed close to the nerve roots and spinal cord, where every millimeter counts
Robot-assisted MIDCAB and Endoscopic coronary artery bypass (TECAB) surgeries are being performed with the da Vinci system. Mitral valve repairs and replacements have been performed. East Carolina University, Greenville (Dr W. Randolph Chitwood), Saint Joseph's Hospital, Atlanta (Dr Douglas A. Murphy), and Good Samaritan Hospital, Cincinnati (Dr J. Michael Smith) have popularized this procedure and proved its durability with multiple publications.
Since the first robotic cardiac procedure performed in the USA in 1999, The Ohio State University, Columbus (Dr. Robert E. Michler, Dr. Juan Crestanello, Dr. Paul Vesco) has performed CABG, mitral valve, esophagectomy, lung resection, tumor resections, among other robotic assisted procedures and serves as a training site for other surgeons.
• In2002, surgeons at the Cleveland Clinic in Florida (Dr. Douglas Boyd and Kenneth Stahl) reported and published their preliminary experience with minimally invasive "hybrid" procedures. These procedures combined robotic revascularization and coronary stenting and further expanded the role of robots in coronary bypass to patients with disease in multiple vessels.
Cardiology and electrophysiology:
The Stereotaxis Magnetic Navigation System (MNS) has been developed to increase precision and safety in ablation procedures for arrhythmias and atrial fibrillation while reducing radiation exposure for the patient and physician, and the system utilizes two magnets to remotely steerable catheters. The system allows for automated 3-D mapping of the heart and vasculature, and MNS has also been used in interventional cardiology for guiding stents and leads in PCI and CTO procedures, proven to reduce contrast usage and access tortuous anatomy unreachable by manual navigation. Dr. Andrea Natale has referred to the new Stereotaxis procedures with the magnetic irrigated catheters as "revolutionary."
The Hansen Medical Sensei robotic catheter system uses a remotely operated system of pulleys to navigate a steerable sheath for catheter guidance. It allows precise and more forceful positioning of catheters used for 3-D mapping of the heart and vasculature. The system provides doctors with estimated force feedback information and feasible manipulation within the left atrium of the heart. The Sensei has been associated with mixed acute success rates compared to manual, commensurate with higher procedural complications, longer procedure times but lower fluoroscopy dosage to the patient.
Multiple types of procedures have been performed with either the Zeus or da Vinci robot systems, including bariatric surgery.
Many general surgical procedures can now be performed using the da Vinci state of the art robotic surgical system.
• In2007, the. University of Illinois at Chicago medical team, lead by Prof. Pier Cristoforo Giulianotti, performed the world's first ever robotic pancreatectomy and also the Midwests fully robotic Whipple surgery, which is the most complicated and demanding procedure of the abdomen.
• In April2008, the same team of surgeons performed the world's first fully minimally invasive liver resection for living donor transplantation, removing 60% of the patient's liver, yet allowing him to leave the hospital just a couple of days after the procedure, in very good condition. Furthermore the patient can also leave with less pain than a usual surgery due to the four puncture holes and not a scar by a surgeon.
Robotic surgery in gynecology is one of the fastest growing fields of robotic surgery. This includes the use of the da Vinci surgical system in benign gynecology and gynecologic oncology. Robotic surgery can be used to treat fibroids, abnormal periods, endometriosis, ovarian tumors, pelvic prolapse, and female cancers. Using the robotic system, gynecologists can perform hysterectomies, myomectomies, and lymph node biopsies. The need for large abdominal incisions is virtually eliminated.
Robot assisted hysterectomies and cancer staging are being performed using da Vinci robotic system. The University of Tennessee, Memphis (Dr. Todd Tillmanns, Dr. Saurabh Kumar), Northwestern University (Dr. Patrick Lowe), Aurora Health Center (Dr. Scott Kamelle), West Virginia University (Dr. Jay Bringman) and The University of Tennessee, Chattanooga (Dr. Donald Chamberlain) have extensively studied the use of robotic surgery and found it to improve morbidity and mortality of patients with gynecologic cancers. They have also for the first time reported robotic surgery learning curves for current and new users as a method to assess acquisition of their skills using the device.
As scientists seek to improve the versatility and utility of robotics in surgery, some are attempting to miniaturize the robots. For example, the University of Nebraska Medical Center has led a multi-campus effort to provide collaborative research on mini-robotics among surgeons, engineers and computer scientists.
Several systems for stereotactic intervention are currently on the market. MD Robotic's NeuroArm is the world first MRI-compatible surgical robot.
The ROBODOC system was released in 1992 by Integrated Surgical Systems, Inc. which merged into CUREXO Technology Corporation. Also, The Acrobot Company Ltd. sells the "[[Acrobot Sculptor==", a robot that constrains a bone cutting tool to a pre-defined volume. Another example is the CASPAR robot produced by U.R.S.-Ortho GmbH & Co. KG, which is used for total hip replacement, total knee replacement and anterior cruciate ligament reconstruction.
Surgical robotics has been used in many types of pediatric surgical procedures including: tracheoesophageal fistula repair, cholecystectomy, nissen fundoplication, morgagni's hernia repair, kasai portoenterostomy, congenital diaphragmatic hernia repair, and others.
• OnJanuary 17,2002, surgeons at Children's Hospital of Michigan in Detroit performed the nation's first advanced computer-assisted robot-enhanced surgical procedure at a children's hospital. The Center for Robotic Surgery at Children's Hospital Boston provides a high level of expertise in pediatric robotic surgery. Specially-trained surgeons use a high-tech robot to perform complex and delicate operations through very small surgical openings. The results are less pain, faster recoveries, shorter hospital stays, smaller scars, and happier patients and families.
• In2001, Children's Hospital Boston was the first pediatric hospital to acquire a surgical robot. Today, surgeons use the technology for many procedures and perform more pediatric robotic surgeries than any other hospital in the world. Children's Hospital physicians have developed a number of new applications to expand the use of the robot, and train surgeons from around the world on its use.
The CyberKnife Robotic Radiosurgery System uses image-guidance and computer controlled robotics to treat tumors throughout the body by delivering multiple beams of high-energy radiation to the tumor from virtually any direction.
The da Vinci robot is commonly used to remove the prostate gland for cancer, repair obstructed kidneys, repair bladder abnormalities and remove diseased kidneys. New minimally invasive robotic devices using steerable flexible needles are currently being developed for use in prostate brachytherapy. A few leading urologists in the field of robotic urological surgery are Drs. Vipul Patel, David Samadi, Ashutosh Tewari, Mani Menon, Peter Schlegel, Douglas Scherr and Darracott Vaughan....read more
Robotic Surgery is the Future of Health Care
In today's world of advanced technology, we are finally making huge strides when it comes to the medical field. The latest and most innovative technology that is found in the medical field today is simply put: robots. More and more are we seeing robots that are assisting the surgeon in the operating room. These robots will help many patients throughout the years, especially as the technology is perfected and upgraded.
Imagine that you have just discovered that you have prostate cancer. The mere thought of having this disease is daunting, let alone having to face a surgery as well. If you find yourself having to have all or part of your prostate removed the doctor will probably recommend that you have a robotic prostatectomy. This procedure will drastically reduce the amount of recovery time that is usually associated with any surgery involving the prostate.
Another major area where robots are highly used is for heart surgery. Although the technology for performing robotic heart surgery is expensive and difficult to find, the overall results being seen from the use of a robot during heart surgery are so great that we should see this technology become more accessible over the next several years. The use of a robot for heart surgery results in a less invasive procedure which in turn provides a quicker recovery time as well.
Hysterectomies are the second most common surgery that is performed each year. Hundreds of thousands of women require the removal of their uterus for a variety of reasons. Women might have this procedure due to uncontrollable bleeding or for cancer as well. More and more hysterectomies are being performed by the assistance of a robot. The use of a robot to perform a hysterectomy is highly beneficial to each patient. As with the prostatectomy and heart surgery, a hysterectomy performed by a robot also results in a less invasive procedure with shorter recovery times. Another benefit for most women is that they will also see less scarring as a result of the procedure. There are many hospitals that provide this robotic procedure. (see our Robotic Surgery Provider pages)
So if you find yourself needing a surgical procedure, perhaps you should discuss the options of a robotic surgery with your doctor. You should also keep in mind that not everybody is a candidate for robotic surgery and it may not be available in some areas. Robotic surgery is still generally new and will take several years for the procedures to catch on. Once the technology becomes more common and less expensive the surgeries should be available to just about anyone.
Why Surgical Robotics Is Unstoppable February 10, 2010
The Bottom Line:
It is the opinion of Robotics Business Review that the proliferation of robotic surgical devices is unstoppable. The potential benefits in the advancement of specialized surgeries, improvement of routine procedures, and reduction in costs, pain, and recovery times, along with other benefits, are simply too great for patients, surgeons, hospitals, or insurance companies to ignore:
Minimally invasive surgery provides advantages over traditional methods, and as a result the number of MIS procedures is steadily increasing, both in absolute number and in the type of clinical procedures available.
Robot-assisted surgery often automates MIS procedures.
The number of academic papers related to robot-assisted surgery is large and growing at a rapid pace, which is an indication of the popularity and relevancy of the topic
Robotics technology addresses many of the limitations of existing MIS techniques, enhances the capability of existing systems, and increases the number of procedures to which MIS techniques can be applied.
Robot-assisted surgery is being used to complement traditional procedures.
Robot-assisted surgery provides real, quantifiable benefits to patients, surgeons, and hospitals.
Hospitals are using robot-assisted surgery as a marketing tool to attract patients and surgeons, as well as support from the government, insurance companies, and other payers.
Demographic shifts due to an aging population in industrialized countries will result in more robot-assisted surgeries.
Robotic Surgery: Applications, Limitations, and Impact on Surgical Education By : Bishoy Morris, MBBCH (Hons) Published: 09/27/2005
The 1990s have witnessed the so-called laparoscopic revolution in which many operations were adapted from the traditional open surgery to the minimal access technique. Shorter hospital stays, reduced postoperative pain, lower incidence of wound infections, and better cosmetic outcomes have made operations, such as laparoscopic cholecystectomy, the standard of care for cholelethiasis. Favorable results prompted surgeons to attempt to develop minimally invasive techniques for most surgical procedures. However, many complex procedures (eg, pancreatectomy) proved difficult to learn and to perform laparoscopically due to technical limitations inherent in laparoscopic surgery. For example, the video camera held by the assistant was unstable and gave a limited 2-dimensional vision of the field, and the primary surgeon was forced to adopt awkward positions to operate with straight laparoscopic instruments, limiting maneuvering. At some point, the growth of the laparoscopic field reached its ostensible plateau, and it seemed that only a new technologic leap could spur further development.
Since the beginning of the 21st century, the emergence of innovative technologies made further advances in minimal access surgery possible. Robotic surgery and telepresence surgery effectively addressed the limitations of laparoscopic and thoracoscopic procedures, thus revolutionizing minimal access surgery. Robotic surgery is expected to continue to comprise a growing part of surgery. It is envisaged that "almost all surgery can and will be performed by robotic surgery in the future. Thus, robotic surgery will not only require special training; it will also change the existing surgical training pattern and reshape the learning curve of residents by offering new solutions, such as robotic surgical simulators and robotic telementoring.

A robot can be defined as a computerized system which has a motorized construction (usually an arm) capable of interacting with the environment.
The field of robotic surgery is fast growing
Some of the major advances that have taken place in the surgical field include options such as: remote surgery, minimally invasive surgery and unmanned surgery.
The robot assisted surgery offers the advantages of precision, smaller incisions, reduced blood loss, decreased pain, and faster healing time. The introduction of robots have revolutionized the medical and surgical fields wherein the doctors have the advantage of treating higher number of patients while the patients have the benefits of minimal time spent in the hospital. All in all, it results in faster treatment and better recovery rate.
The da Vinci robotic surgery is carried out with the help of the da Vinci Surgical System. This surgical system is comprised of three major components: the console (through which the surgeon performs the operation), side robotic cart (placed by the side of the patient) that has 4 robotic arms that can be manipulated by the surgeon from the console, and a high-definition 3D vision system.
Today robotic surgery is used to perform different procedures such as surgery for prostate cancer, hysterectomy and mitral valve repair. It is currently being used in more than 800 hospitals across America and Europe. Advantages of the da Vinci robotic surgery include the following:
Decreased hospital stay
The disadvantages of the da Vinci robotic surgery include:
Longer learning period
High cost of the equipment and maintanance and thereby the procedure
