We're a little ambivalent about robots performing surgery autonomously and unattended, but there are clearly cases where it'd be beneficial, and it seems like an inevitable future. Duke researchers working on robo-doc lab feasibility studies announced this week a proof of concept using 3D ultrasound mapping to enable machines to "see" what they're doing. The first test procedures have focused on use of those ultrasound transducers in catheter-based procedures using fluoroscopy, so it sounds like we'll still have a few years before we say ahhh for a machine.

Okay, so we're not exactly doctors, but we couldn't help but be intrigued by PEAK Surgical's announcement today that its PlasmaBlade electrosurgery scalpel had completed preclinical testing with positive results. Unlike traditional electrosurgery tools like the bovie cutter, the PlasmaBlade operates at low temperatures, using pulsed plasma energy to cut tissue and control bleeding. Then, stupidly, we watched the video. Let's just say now that it no longer matters to us that surgeons using the PEAK PlasmaBlade produce "minimal collateral damage" to tissue and that bleeding was reduced. Sure, it's great for the surgeons, but our eyes? Not going to be the same.

Researchers at Osaka University are redefining "thought-controlled" limbs. Hailed as the first endeavor to dabble in the world of bionic phalanges by requiring open-skull surgery, the research is seeking to develop "real-time mind-controlled robotic limbs for the disabled." Of course, it's not the goal that's striking, but the means. Essentially, gurus working on the project are hoping to place electrode sheets directly on the surface of the brain in order to "obtain a more accurate signal," and amazingly enough, they're currently working to sign up willing subjects that are already scheduled to have brain electrodes added to deal with "monitoring epilepsy or other conditions." Maybe the bionic beings really aren't that far off, eh?

Proving that children and the elderly are not the only groups seeing benefits from Nintendo's Wii, a study on a small group of surgeons who had practiced gaming with a modified controller showed them to achieve significantly more improvement on a standard simulator procedure than did a corresponding group of control subjects. Study author Kanav Kahol worked with Dr. Marshall Smith of the Banner Health hospital chain to build a special Wiimote attachment (read: broken golf club add on + laparoscopic probe) that eight surgical residents used to play Marble Mania and the full suite of Wii Play games. The gamers were then pitted against eight of their less-fortunate colleagues in a computer-simulated laparoscopic procedure, and managed to attain 48% higher scores, on average, than the non-gamers. Unfortunately, games involving broader motions such as tennis or boxing are said to be less suitable for this sort of training, make a total liar out of your doctor the next time you catch him "honing up on the latest techniques" by playing Wii Golf.

Yeah, we gave you a plethora of hatching photos to ooh and ahh over when we received our first Pleo, but considering our inexplicable fear of needles and prehistoric blood, we never considered taking things any further. Apparently, the folks over at Pleo Dreams completely disregarded our recommendation to not de-skin the dinosaur, and proceeded to remove every square centimeter of Pleo's covering on video. Believe it or not, things get pretty interesting once the garb comes off, but you'll have to endure a near-24 minute clip in order to say you saw the entire procedure from start to finish. You ready? It's waiting after the break.

A robot that crawls through your innards? Yeah, we've been there, done that on a number of occasions, but a new alternative being developed by a team at Imperial College London could reportedly "revolutionize keyhole surgery." The aforementioned crew has been granted some £2.1 million ($4.19 million) in order to further develop the i-Snake, which is a "long tube housing special motors, sensors and imaging tools." Apparently, the creation would be used in heart bypass surgeries, to "diagnose problems in the gut and bowel" and to generally act as a surgeon's hands / eyes in hard to reach locales within the body. Per usual, we've no idea when it'll be ready for mainstream use, but hopefully the i-Snake will be slithering through citizens sooner rather than later.

We were always of the opinion that robot surgery was edgy enough as it is, but you know how those science peoples always have to kick things up a notch. SRI International and the University of Cincinnati hitched a ride on NASA's DC-9 "vomit comet" to pit human surgeons against semi-autonomous robots in suturing and incision tasks on simulated tissue -- while experiencing periods of zero gravity and 1.8g acceleration. Surprisingly, the robots kept pace just fine until SRI's fancy compensation software was switched off, which we're guessing is exactly the point SRI was trying to prove. Right now SRI is building a robotic operating room for the battlefield called Trauma Pod, which is mostly autonomous, and they're also working on a fully autonomous system for NASA that could treat an astronaut on Mars, where the 20 minute delay would make telesurgery not an option. Field testing for the trauma pod should begin in 2009.

Thankfully, doctors aren't actually be instructed en masse how to do their work by robotic teachers, but that's not to say robots aren't helping to facilitate the learning process. Recently, surgeons in Argentina were guided through a laparoscopic gastric sleeve procedure by a colleague some 5,400 miles away thanks to the InTouch Health RP-7 Remote Presence Robot. The five-foot, five-inch robot reportedly "displays the doctor's face on a 15-inch screen and is guided by a joystick from a computerized ControlStation, emulating an on-site experience." It's even able to provide high quality, real-time audio / video with "complete mobility around the operating room." Best of all, the patient in question was actually able to return home shortly after the procedure was complete, but heaven forbid one of these things ever turning on us humans and taking on a personality of its own.

Combining zero gravity with robots performing surgery probably isn't the average person's idea of a fun time, but that's what scientists envisage as the future of the robo-surgery sphere. A NASA C-9 transport aircraft in a 34,000 feet dive towards New Mexico is to be the base for this test, which will compare a prototype robot's ability to cut and stitch with that of a human. Researchers from SRI International and the University of Cincinnati will make the judgment, although it's unclear what exactly the two competitors will be working on. To top things off, the robot surgeon in the sky will be remotely controlled from the ground: to that we can only say, "show offs."

While some courageous individuals may not mind a lifeless being slicing them up in the name of health, there remains a number of us who'd still rather have a human counterpart handling their operation. Thankfully, even skilled doctors could soon be given a hand by GPS location techniques, which have already assisted in some joint-replacement procedures. Essentially, the technology dishes out a "three-dimensional view of the joint area on a television monitor," and enables the knife wielder to make "more accurate cuts and place prostheses much more accurately." The signals are generated by a trio of tiny satellites that are inserted into the surgical incision and "triangulate the exact position of surgical instruments and the anatomy of the patient." Just be careful one of those things don't get sewn up in you, or else you'll likely be a walking beacon for the rest of your days.

While dexterous robots have been helping surgeons in America for some time, Edmonton's Royal Alexandra Hospital is finally getting with the program. Beginning in September, a four-armed surgical robot will be used in procedures to treat prostate cancer, and should provide a much improved in-depth view of the body as well as boosting overall agility while operating. One of the diminutive arms will grasp a camera while the others wield the tools, and trained surgeons will be controlling the action from a three-dimensional screen positioned at a nearby base. Notably, one of the primary reasons Canada has been slower to adopt this type of technology is the price, and while it did cost some $4 million to purchase and retrofit the system into the OR, the shorter recovery time and improved precision whilst operating will certainly prove worthwhile to the average patient.

High-definition capture and monitoring equipment has long been available for medical uses, but for whatever reason, widespread use has yet to catch on. Now, however, you people will be able to um, partake, in viewing the "first HDTV surgery ever broadcast" as National Geographic HD airs a special presentation of the 1080p system in action. According to a doctor that actually got to experience the technology first-hand, the KSEA HDTV Surgical System provides a widescreen, Full HD look at what's going on within, employs a 3CCD camera with an acquisition resolution of 1,920 x 1,080, and outputs an image that is progressively scanned and displayed at 60 full frames-per-second. We'd recommend you tune in to the aforementioned show on September 16th if the channel is available in your neck of the woods, but you may want to click on and see a few stills of the KSEA in action before subjecting yourself (read: your weak stomach) to the real deal.

We know the Hippocratic Oath is kind of implied in Asimov's Three Laws, so we're kind of cleared for takeoff when it comes to robots performing surgery on us hapless meatbags. But we imagine no such laws or oaths apply to robots developed by UBC physics students, whose final exam is to build the best machine for playing a life-sized game of Operation. And not a moment too soon, because this case of writer's block is totally killing us -- so we'll just end the post here.

Hearing that a cellphone saved someone's life isn't exactly surprising these days, but it was the manner in which a bundle of handsets enabled doctors to continue on in a recent operation that differentiated this one from the rest. Reportedly, the backup generators at the Policlinico Juan D. Peron hospital in Argentina failed to activate after the power went out whilst an appendix surgery was ongoing, but rather than panicking, a family member gathered up a number of phones in order to provide enough light for the surgeons and anesthetists to keep on keepin' on. According to the hospital director, the operation went on without proper lighting for no more than 20 minutes, but thanks to the beaming LCDs, the fellow under the knife came through just fine.

Satiety, Inc. has finally found the funding it needs to push forward with a radical new approach to assisting the obese, as it has rounded up $30 million in financing from a number of venture capitalists who dug the idea. Essentially, the TOGa procedure is a "completely transoral process designed to achieve similar weight loss to restrictive surgeries," and it also claims to be less invasive, require less recovery time, and should create a "dramatically reduced amount of complications." In this system, the physician would "introduce a stapling device transorally and create a restrictive pouch at the entry of the stomach," and moreover, it's considered "non-surgical" in nature, endoscopic, and can be performed by properly trained bariatric surgeons, general endoscopic surgeons, and gastroenterologists. Currently, the firm is moving forward with plans to get the procedure approved by the FDA, and while there's no telling how long such a convoluted process will take, stomach stapling could see an entirely different approach in the years to come if this proves effective.
