Professor James Wolffsohn from Aston University in the United Kingdom imagines that within the next decade, the cure to near- and farsightedness will not only exist, but will actually be within reach. While the underlying idea of replacing biological lenses with minty-fresh artificial ones isn’t necessarily new (think cataract surgery), Wolffsohn’s efforts will allow patients to focus both near and far, instead of just plain old, boring far. While the details on how the lenses work are a little scant (read non-existent), apparently eye muscles squeezing the “ultra-flexible” devices allow the actual focusing to occur. The professor has been working with opthology companies to commercialize the specs, and envisions the procedure costing less than £1,000 within the next five to ten years. Sounds good to us, because fancy new lenses or not, as people who stare at computer screens all day, the odds of us going under the laser at some point are a tad on the high side.

While the scientists that developed these newfangled ingestible microgrippers call them minimally invasive, we’re not so sure that swallowing minuscule devices that can cut and grab tissue when chemically activated fits our definition of keyhole surgery. Nevertheless, tiny “handlike grippers” are currently being shown off to highly intelligent professionals in the medical realm, and if proven feasible, they could one day be used to perform biopsies from within. More specifically, the devices could reportedly “react to the biochemicals released by infected tissue by closing around the tissue, so that pieces can be removed for analysis.” Yeah, we reckon this is a bit less painful than actually going under the knife, but the mere thought of having blade-wielding microorganisms floating around our innards spooks us just a wee bit. Go on, fling your “pansies!” this way — we can take it.

Neurosurgery with robotic assistance is getting pretty old hat nowadays, so it looks like scientists are trying to up the difficulty factor by keeping their patients awake — a team of French doctors just completed the first successful removal of malignant brain tumor from a still-conscious patient, using a computerized laser and an MRI scanner to guide the probe. The fiber-optic laser was fed into the brain through a 3mm (.12 inch) hole in the patient’s skull and guided via MRI to the tumor, where it fired for two minutes and completely destroyed the cancerous tissue. Once the tumor cells were dead, the cable was removed and the patient was allowed to return home — all within a single day. That’s pretty impressive, and it comes on the heels of 15 similar trials where five out six patients who underwent the total removal procedure were cancer-free nine months after surgery. The team says further research will cost an additional two million euros to progress, but if this technique works as well as they claim after peer review, we’d guess that money won’t be hard to come by.

In operating rooms today, cancer surgeons are essentially forced to operate without any definitive way of determining whether or not 100% of the diseased tissue has been removed. Thanks to a radical invention by researchers in Massachusetts, that huge limitation could soon be a thing of the past. A new system, dubbed FLARE (Fluorescence-Assisted Resection and Exploration), involves a near-infrared (NIR) imaging system, a video monitor, and a computer. These tools are used to see special chemical dies (christened NIR fluorophores) that are crafted to “target specific structures such as cancer cells when injected into patients.” When these dyes are exposed to NIR light, the cancer cells light up, giving doctors an easy look at what they have left to remove. The team is gearing up to showcase the technology at the American Chemical Society national meeting in Philadelphia — here’s hoping it can be put to good use in the very near future.

We’re still a bit gun shy when it comes to surfing over to PEAK Surgical’s website after watching that PlasmaBlade demonstration video, but a new release from the outfit affirms that said electrosurgery scalpel has just been approved for use by the US Food and Drug Administration. The “tissue dissection system,” as it’s so gruesomely called, has been given 501(k) clearance, meaning that PEAK can now market its tool for use in general surgery. So, anxious to camp out and be the first in the country to get sliced and diced by one of these? Bombard your local hospitals with phone calls starting next month.

Sheesh — and we though it was something special when Teddy Ruxpin went digital. Today’s mesmerizing bear just isn’t remarkable unless it talks, and to make it extraordinary, it needs to vocalize your Twitter messages. The mad scientists over at 2pointhome were able to implant a circuit board, USB Bluetooth adapter, 9-volt battery and a host of other goodies into an animatronic Teddy, and after coding in a few things and pairing it up, the animal was yapping in no time flat. Head on past the break to see a video of the operation, but be warned, as it’s not for the faint of heart.

Though it’s certainly not the first time a robotic surgeon has made news after joining the staff at a Canadian hospital, history has just been made in Calgary. Doctors (the human kind) were able to use remote controls, an imaging screen and the neuroArm in order to successfully remove a brain tumor from a 21-year old woman. Hailed as the first procedure of its kind, the team already has a line of patients waiting to receive similar surgeries, and the mechanical hand is being praised for its precise movements and delicate nature. Unfortunately for the arm, no pay raise (or extended vacation) is in sight.

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.
