Telelap ALF-X Endoscopic Robotic Surgical System
March 21, 2014
Intuitive Surgical is the dominant player in robotic surgery, having developed the now famous da Vinci System that turned traditional endoscopy into a futuristic endeavor. Now we learn of a system being developed by SOFAR, an Italian pharmaceutical firm, that looks set to compete with the da Vinci.
The Telelap ALF-X features haptic feedback, allowing the surgeon to indirectly “feel” the tissues that are being manipulated. This can lead to improved safety and allow certain maneuvers to be performed with greater confidence. The system also tracks the surgeon’s eye movements, positioning the camera so the field of view is centered where the eyes are looking. The system is highly adjustable for an optimal ergonomic experience. Click Here to view video previews of the system in action

Robotic arm to aid in heart surgeries in Trenton
March 15, 2014
A new $2 million robotic arm that has been installed at St. Francis Medical Center in Trenton will allow doctors to perform heart surgeries that were not previously available in the region, officials said.
Hamilton Cardiology Associates announced this week that its surgeons will be able to use this technology for procedures that were only offered in Philadelphia and New York City.
The arm is part of a new “hybrid” operating room that crosses a cardiac catheterization lab and a traditional OR, St. Francis said in a release. Catheterization labs are used for minimally invasive catheter procedures such as balloon angioplasties, while standard operating rooms are used for more invasive procedures such as open-heart surgery, the release said.
“The hybrid (operating room) enables physicians to do procedures that may require minimally invasive and open-surgery techniques simultaneously,” Patel said......read more

Stanford surgeon shows us the future of medicine with augmented reality & Google Glass
March 13, 2014
With his Google Glass, Stanford University physician Dr. Homero Rivas pinpoints a target on the skin of an anatomical human model.
The surgeon and his assistant then direct their Glass at the target to reveal an augmented reality display on their screens. To their eyes, looking through the Glass, they can see the procedure illustrated step by step with images superimposed over the skin of the model.
Stanford University live-streamed that demonstration to physicians around the world. It wasn’t a particularly complicated procedure, but it was one of the first times that augmented reality has been introduced to Glassware for the benefit of surgeons.
Dr. Rivas was experimenting with a new Google Glass app called “MedicAR,” which was developed by European app maker Droiders. Dr. Rivas met Droiders chief executive Julian Beltran at a recent event and realized they shared a mutual interest in wearable tech. He does not have a paid relationship or consulting agreement with the firm.
Augmented reality (AR) is a popular entertainment tool, but it has its limitations. Today, you’re usually required to hold a smartphone between you and what you’re viewing. Integration with smart glasses such as Glass will enable us to view augmented images without the barrier of a phone. It clearly has value for the entertainment industry and advertisers, but Droiders also sees opportunities for health care.....read more
Another kind of personalized medicine: Custom-made surgical robots built for one patient.
T hree women speaking about robots in the OR. Katherine Kuchenbecker, Allison Okamura and Catherine Mohr talked about robots in the OR, how they are used now and how they are being adapted and revised and improved.
Mohr is the senior director of medical research for Intuitive Surgical. Kuchenbecker is an associate professor of mechanical engineering and applied mechanics at the University of Pennsylvania. Her research centers on the design and control of haptic interfaces.
Okamura has a BS, MS and PhD in mechanical engineering. She is a associate professor in the mechanical engineering department at Stanford University. A medical robotic researcher, she is working on the challenge of pediatric surgery and looking for an answer to the question: How do you get robots deep in the body in a dexterous way?
Most robots used for surgery are too big to use during surgery on children. A better tool has to be:
As small as possible
Able to move in a curved path
Able to deliver therapy
Able to be used for a specific procedure with a specific patient
Okamura said that current examples of this kind of tool include devices used to do cochlear implants and capsule robots used to take pictures or polyp samples in the colon........continue reading
Minimally Invasive Devices Launches Robotic FloShield'' to Enhance Visibility During Robotic Surgery
March 10, 2014
Minimally Invasive Devices, Inc., an Ohio-based, venture-backed medical device company that specializes in optimizing the surgeon's vision during laparoscopic surgery, today announced the commercial release of Robotic FloShield, designed specifically to be compatible with the da Vinci Surgical System for robot-assisted laparoscopic surgery.
"Hospitals invest millions of dollars in da Vinci robotic systems, but the accumulation of condensation, debris and smoke while the laparoscope is in use forces surgeons to disrupt their work to clean the camera," noted Wayne Poll, M.D., founder and CEO of Minimally Invasive Devices and a robotic surgeon. "For such high technology systems to be fettered by such basic problems is unacceptable, which is why we developed the Robotic FloShield system."
FloShield technology uses Vortex Barrier Technology (VBT), which forms an invisible curtain of gas in front of a laparoscope's optics that acts as a barrier to debris, condensation and smoke, preventing the accumulation of vision-disrupting particulates. FloShield VBT is the first system that pushes smoke and debris away from the laparoscope lens surface before it can settle on the optics and disrupt a surgeon's view.....read more

NJ doctor wearing Google Glass peers into future of surgery
March 10, 2014
At this stage in the rollout of Google Glass, it may seem the gadget’s "cool factor" exceeds its practicality.
For cardiologist Jordan Safirstein, however, it has already taken its rightful place in the operating room alongside his other surgical equipment. He’s found his Glass has quickly become everything from a lectern to a blackboard to a telephone.
"Okay, Glass: Make a video call," Safirstein said in a firm voice as he began a recent cardiac catheterization and stent insertion on a 41-year-old patient.
Google Glass, unveiled in 2012, is a wearable computer with a miniature, head-mounted display screen smaller than a Scrabble tile. The wearer sees it as a tiny image floating in one’s peripheral vision.
It can follow voice instructions to get information, take photos, make a phone call, or shoot and store video.
In Safirstein’s case, it video-streams whatever is in his field of vision, sending it to Google Hangout, where his students can view it live on their smartphones or tablets.......continue reading
Cardiac surgeon’s suspension puts UA patients in limbo
March 9, 2014
A highly specialized cardiac surgeon has been suspended from the University of Arizona Medical Center, leaving patients scrambling for alternatives.
Hospital officials confirm that Dr. Robert S. Poston is not performing surgery because he does not currently have clinical privileges. Poston, who came to Tucson from the University of Chicago in 2011, is the hospital’s director of adult cardiac surgery. He has a national reputation for specializing in minimally invasive robotic coronary-bypass surgeries that don’t require splitting the sternum.
UA Medical Center officials say Poston is suspended with pay. UA records as of November listed his salary as $400,000.
Poston would not comment. A complaint he filed against the hospital in Maricopa County Superior Court on Feb. 5 describes a political and unjust peer review process. It says some of his colleagues were not receptive to the new, innovative cardiac surgery he brought to the hospital, which is why they maligned him.
Poston’s lawsuit says his hospital peers made a politically motivated effort to “destroy the robotic cardiac surgery program and Dr. Poston’s career.” It says that he was criticized by doctors whose income would be affected if he succeeded.
Poston’s sudden absence means patients like Tucson business owner Jim Viberg aren’t getting the robotic surgery they expected. A liver transplant recipient with hepatitis C, Viberg, 65, says a traditional cardiac bypass would put him at too much risk for infection and blood loss. And the traditional bypass surgery of cracking the chest would require a longer recovery time that would put him out of work for an extended period of time and hurt both his business and employees.
The UA Medical Center is “is choosing to not perform” robot-assisted cardiac bypass procedures at this time, department of surgery spokeswoman Jo Marie Barkley wrote in an email Friday......read complete article
Tandem Robot Assisted Laparoscopic Radical Prostatectomy (T-RALP)
Tandem Robot Assisted Laparoscopic Radical Prostatectomy (T-RALP)
Robot-assisted laparoscopic radical prostatectomy (RALP) using daVinci®surgical robot system (Intuitive Surgical) has gained wide acceptance for the treatment of clinically localized prostate cancer. The preservation of the neurovascular bundle (NVB) including cavernous nerves during the surgery improves the postoperative recovery of sexual potency. However, NVB visualization can be challenging due to the periprostatic connective tissue and intraoperative hemorrhage. The accompanying blood vessels in the NVB, which are visible with Doppler ultrasound, can serve as a macroscopic landmark to localize the microscopic cavernous nerves in the NVB.
A novel robotic transrectal ultrasound probe manipulator (TRUS Robot) is used concurrently with the daVinci® in a tandem robot approach (T-RALP) to intraoperatively image the prostate and NVB. The TRUS Robot was developed to provide a steady holding of the TRUS probe and allow remote manipulation using a joystick located next to the daVinci® console......continue reading

Study finds robotic-assisted prostate surgery offers better cancer control
Posted on AARS: March 1, 2014
An observational study from UCLA's Jonsson Comprehensive Cancer Center has found that prostate cancer patients who undergo robotic-assisted prostate surgery have fewer instances of cancer cells at the edge of their surgical specimen and less need for additional cancer treatments like hormone or radiation therapy than patients who have traditional "open" surgery.
The study, published online Feb. 19 in the journal European Urology, was led by Dr. Jim Hu, UCLA's Henry E. Singleton Professor of Urology and director of robotic and minimally invasive surgery in the urology department at the David Geffen School of Medicine at UCLA.
Although it is becoming more popular, robotic-assisted radical prostatectomy—the complete removal of the prostate using a robotic apparatus—remains controversial because there has been little evidence that it provides better cancer control than open radical prostatectomy, the traditional surgical approach, which is less costly.
In an effort to determine whether or not robotic surgery offered an advantage, Hu and his colleagues compared 5,556 patients who received robotic surgery with 7,878 who underwent open surgery between 2004 and 2009. Data was provided by the Surveillance, Epidemiology, and End Results–Medicare, a program of cancer registries that collect clinical and demographic information on people with cancer......read more
