In a case of its own kind, doctors at a private hospital removed a big tumour located behind the right kidney through robotic surgery.
The doctors were called to the University of Illinois at Chicago, United States to make a presentation on the rare surgery. It also appears on the website of Clinical Robotic Surgery Association, a leading body in the field.
“Usually tumours behind kidney, called retroperitoneal lump, get diagnosed by the time they are of the size of five or six cm. In the present case, tumour size of the lady had increased to 12.2 x 8.5 x 8.2 cm. We decided to perform robotic surgery instead of open surgery so that the patient can recover faster,” said Dr Parveen Bhatia, one of the treating surgeons and head of Institute of Minimal Access, Metabolic and Bariatric Surgery at Sir Ganga Ram Hospital.....read more

Robotic neobladder technique appears promising
October 17, 2012
A neobladder reconstruction technique that is performed using robotic assistance appears to be a safe, less invasive option in patients with aggressive bladder cancer.
Surgeons at The Methodist Hospital in Houston and other institutions around the country developed the technique, results of which were presented at a European Association of Urology meeting on robotic surgery in London last month and will be published in the November issue of European Urology.
Alvin C. Goh, MD, of The Methodist Hospital and The Methodist Institute for Technology, Innovation, and Education, presented data from a study of 24 patients eligible for the novel robotic reconstruction. Three-month follow-up data were analyzed for eight patients who received a neobladder and seven patients who underwent an ileal conduit diversion....read more
Rising Eye Injury Rates Seen With Robotic Prostate Surgery
October 16, 2012
Patient position during procedure or other unknown cause may lead to scratches on cornea.
The number of eye injuries associated with robotic-assisted radical prostatectomy -- complete removal of the prostate -- increased nearly tenfold in the United States between 2000 and 2009, although the risk was still small, a new study finds.
During that time, the incidence rate of eye injuries rose from 0.07 percent to 0.42 percent, according to the review of more than 136,000 such procedures. Most of the injuries involved corneal abrasion, or scratching of the eye surface.
While undergoing robotic-assisted radical prostatectomy, patients are positioned head-down and are at risk for facial swelling, arm injuries, as well as corneal or other eye injuries, the researchers explained.
Possible causes of eye injuries during robotic-assisted radical prostatectomy include the long duration of surgery, patient positioning or something associated with the robot itself, said Dr. Ajay Sampat and colleagues at the University of Chicago.....read more
Intuitive Surgical sued over heart stabilizer patent
October 10, 2012
Alisanos LLC sues Intuitive Surgical, alleging that the da Vinci surgical robot infringes on an Alisanos patent for a heart stabilization device.
Intuitive Surgical's(NSDQ:ISRG) da Vinci surgical robot infringes at least 1 claim of a patent owned by Alisanos LLC, according to a lawsuit.
Alisanos, a Longview, Texas-based intellectual property development and licensing company, accused Intuitive of learning the ins and outs of its patent for the so-called "'573 patent, or "Through-Port Heart Stabilization System," when they began negotiation over a possible partnership in November 2000 – even as Alisanos' corporate predecessor, Medcanica/POPCAB, was seeking the patent, according to court documents. A feature of Intuitive's flagship da Vinci devices called the EndoWrist Stabilizer allegedly violates the patent, Alisanos claimed.
"After gaining knowledge of Medcanica/POPCAB’s proprietary information, Intuitive claimed to be interested in forming a 'product development relationship' with Medcanica/POPCAB whereby Medcanica/POPCAB would adapt its existing inventions (which shortly thereafter formed the basis of the ’573 patent application) to be used within Intuitive’s 'ISI Robotic Surgical System,'" according to the documents......read more
Robotic Surgery Aces in The Removal of Tumors of The Throat And Voice Box
october 9, 2012
Transoral robotic surgery, which is a recent development in the minimally invasive surgical techniques, has got the seal of safety and effectiveness according to a recent literature published in the journal Head and Neck by Dr. Enver Ozer. The surgeons of head and neck cancer at the Ohio State University Comprehensive Cancer Center – Arthur G. James Cancer Hospital and Richard J. Solove Research Institute, also known as OSUCCC – James, were involved in this study. This is the first ever literature elucidating the safety and efficacy of transoral robotic surgery for the removal of tumors of the throat and the voice box.
Although, transoral robotic surgery has got the FDA approval for usage in certain surgical procedures, the surgeons wanted to know if it was safe for removing cancers of the head and neck, specially that of the supraglottic region. The study looked at the outcomes of 13 head and neck cancer patients who had tumors in their throat, between the base of the tongue and just above the vocal cords, medically known as the supraglottic region. These 13 patients were a part of the larger study that included 126 patients undergoing transoral robotic surgery between the year 2008 and 2011.

Researchers test zero-gravity surgery device
October 5, 2012
University of Louisville researcher to test a potentially lifesaving surgical device aimed at helping make zero-gravity surgery possible.
George Pantalos, a professor of surgery and bioengineering, and colleagues from Carnegie Mellon University are conducting four days of tests this week in Houston aboard a NASA zero-gravity jet known as the "vomit comet," which flies in gut-churning parabolic arcs to generate 20 to 30 seconds of weightlessness.
They're testing prototypes of an "aqueous immersion surgical system" -- an airtight and watertight dome with surgical ports that would be filled with saline and surround a wound in a zero-gravity environment. The idea is to stop bleeding and contain fluids that would otherwise float through the spacecraft, potentially endangering the patient and crew.
To test the concept, the researchers used plastic containers inside a prenatal care box. The researchers, held in place by foot straps, successfully controlled artificial blood coursing through a simulated vein Tuesday. On Wednesday, they conducted a simulated surgical procedure on a pig's heart.
Pantalos, 60, is working on the device with Pittsburgh-based Carnegie Mellon bioengineering researchers James Antaki, Jennifer Hayden and James Burgess.
Pantalos, attached to the University of Louisville's Cardiovascular Innovation Institute, is a veteran of space flight research. He's conducted tests on 28 weightless flights, in one instance developing a modified zero-gravity heart resuscitation procedure that is now part of astronaut training.
There has been previous research on surgery in zero gravity.
Quantum International (PINK: QUAN) is looking at using nanobots—very, very tiny creations—to attack cancer. And it’s pretty promising.
At the NanoRobotics Lab in Canada’s École Polytechnique de Montréal, scientists have successfully steered tiny robots wirelessly through blood vessels of living organisms with the aid of magnetic coils found in MRI machines. These microscopic robots can easily access places within the body that catheters cannot, and they can execute incredibly precise maneuvers that would otherwise require invasive surgery.
The company is, at present, close to clinching a deal with the Polish Industrial Research Institute for Automation and Measurement to commercialize the Resuscitator – a portable device that could help ensure chest compressions are administered perfectly. Compressions, the most vital part of CPR, are also the most prone to human error, and broken ribs are not uncommon......complete story
Eldery Patients With Colorectal, Bladder Cancers May Benefit From Advanced Surgical Approaches
October 4, 2012
Separate studies report robotic-assisted and minimally invasive operations may extend patients’ life spans with fewer complications
Advanced surgical techniques such as robotic-assisted operations and minimally invasive surgical procedures may extend survival and improve recovery in octogenarians with bladder and colorectal cancers when compared with patients who undergo conventional open operations according to two new studies presented at the 2012 Annual Clinical Congress of the American College of Surgeons.
Boston University investigators found robotic-assisted bladder procedures may be a viable option in selected patients aged 80 years and older who would not otherwise have an operation to remove the cancer, according to Vikrant Uberoi, MD, a urology resident, Boston University (BU) School of Medicine, who presented the findings. Researchers conducting a separate study of minimally invasive colorectal operations found that the laparoscopic surgical approach achieved favorable outcomes when compared with traditional open operations, said study presenter Therese Gannon Kerwel, MD, a fellow in colorectal surgery at Spectrum Health, Grand Rapids, MI.
New surgical tool steadies itself for delicate procedures
Posted; October 2, 2012
Surgeons study long and hard to perfect their technique, but one thing they can't control is the microscopic shifts that exist in even the steadiest of hands. Researchers have tackled this problem by creating a surgical tool that compensates for these shifts.
The tool, named SMART (Smart Micromanipulation-Aided Robotic-surgical Tool), determines its location by sending out tiny pulses of light via optical fiber; the harmless light hits the tissue and is picked up by the same fiber. SMART measures any motion of the surgical tool by calculating the time it takes for the light to bounce back.
SMART then uses motors powered by pressure and movement to shift its surgical tip. The hyper-accurate motors are able to move as often as 500 times a second, which more than compensates for the average, natural invisible shifts the human hand makes — some 50 to 100 microns several times a seconds, which is about the width of a human hair.
Researchers tested the motors with two surgeons and found......read more

The adoption of robot-assisted technology truly represents a step forward in our field.”......complete story
Researchers Announce New Curriculum Sharing For Surgeons
October 1, 2012
A first of its kind program for surgeons has been developed by a team of researchers at the University of Southern California and Mimic Technologies that will help identify which training programs are working for robotic surgery. The new technology, called MShare, provides a forum for surgeons and hospital administrators, worldwide, to communicate and share curricula that have been validated by new research.
The new system was unveiled at the American College of Surgeons conference on September 30.
Prior to the introduction of MShare, hospital administrators and surgeons lacked a forum on which to collaborate and/or share simulation training curricula on the dVTrainer, the training hardware for the da Vinci robot, the most extensively used robot in surgery centers.
Mimic Technologies, the simulation company that built the da Vinci simulation platform, is developing MShare, which will allow surgeons to share curricula they have validated, as well as distribute what has been effective for training within their departments or surgical disciplines.
Surgeons will choose and post new training programs from high-demand categories. MShare also offers a public space for surgeons to journal their experience — notes that can prove valuable for the development of future training programs......read more
