Robot Hall of Fame expands to include Da Vinci, Terminator, Roomba

by Darren Murph posted May 11th 2009 at 9:34AM

Forget those "sporting" Halls of Fame -- the real HOF is right here. Since 2003, the Robot Hall of Fame has been honoring robots and creators at an exhibit in Pittsburgh, Pennsylvania, and now we're seeing the latest handful of noteworthy creatures take their rightful place in history. For those unaware, the Robot HOF is maintained by Carnegie Mellon University and the Carnegie Science Center, and an international jury of researchers, writers, and designers has just selected five new bots to join the cast: Mars rovers Spirit and Opportunity, the T-800 Terminator (yes, that Terminator), the Da Vinci surgical system, iRobot's Roomba and 'Huey, Dewey, and Louie' from the 1972 sci-fi flick Silent Running. Could you have imagined a more fitting five? If so, sound off below!

Video: da Vinci Si robotic system wants to be your surgeon

by Thomas Ricker posted Apr 7th 2009 at 5:54AM

Oh boy, from the looks of that picture the only perquisites for using the updated da Vinci Si surgical system are video game skills, a preference for interacting with the physical world on a high-def display, and an abnormal interest in robots. Sound like anyone you know? Intuitive Surgical's latest robotic system features two separate HD optical channels that the manufacturer claims will give "highly accurate depth perception" when merged. The surgeon console features touchpad control of the video, audio, and system settings while providing "precise, dexterous control" of a an extensive array of surgical tools held by the robotic flanges. Perfect for all your minimally invasive, WebMD-inspired home surgery needs when not performing transplants at county. Check the video after the break -- amazing is an understatement.

Eizo debuts 56-inch 4k x 2k RadiForce LS560W LCD monitor

by Darren Murph posted Apr 2nd 2009 at 1:29PM

Eizo's known for doling out less-than-affordable LCD monitors, but this one just takes the crown (for now). Slated to dazzle in operating rooms everywhere this July, the RadiForce LS560W is a 56-inch behemoth of an LCD that boasts a resolution of 3,840 x 2,160 (or darn close to native 4k x 2k). We're also told that the panel features a 176-degree field of view, a 1,200:1 contrast ratio and 450 nits of brightness. And to think -- we were beginning to wonder if all that 4k surgery footage would ever find a dedicated screen to run on.

Waseda University's heartbeat compensation robot be stills our hearts

by Thomas Ricker posted Mar 27th 2009 at 4:42AM

Look closely. No, closer. See that slab of pink meat in the middle of Waseda University's surgical robot? That's a heart... now imagine it's your heart. Don't worry, if you ever do pit flesh-to-servo against this device, it'll likely be saving your life during a coronary bypass. After making a small incision, the robot compensates for the natural shake and movement of the organ caused by heartbeats so that surgery can proceed as if the organ is still. That little trick could enable minimally invasive, endoscopic heart surgeries in the future -- no need to crack open the chest cavity. Amazing stuff. See a close-up after the break. You: it's what's for dinner.

Laser-bonded healing could replace needle and thread

by Darren Murph posted Feb 15th 2009 at 1:01AM

It sounds more like something you'd see in X-Men than on an actual operating table in real life, but a team at Massachusetts General Hospital has developed a way to heal surgical incisions with laser light. Christened laser-bonded healing, the methodology has been studied for years, but up until now, scientists have found it impossible to find the perfect balance of heat required to coax tissue into healing itself back together. Irene Kochevar described the process as "nano suturing," as diminutive collagen fibers are woven together in a way that the old-fashioned needle-and-thread method simply can't match. The benefits, as you can likely imagine, are numerous: less scarring, faster recovery, the potential for fewer infections and bragging rights that you were struck with lasers and survived. Still, the procedure is far from becoming commonplace in ORs, given that the dermatological procedure hasn't even been submitted to the FDA yet. 'Til then, it's up to you and Wolverine to figure things out.

Bionic lens to debut in the next half-decade

by Dante Cesa posted Sep 12th 2008 at 11:01AM

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.

Swallowable microgrippers could make surgery more / less invasive

by Darren Murph posted Sep 1st 2008 at 7:19AM

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.

French doctors use laser to destroy brain tumor in conscious patient

by Nilay Patel posted Aug 30th 2008 at 3:12PM

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.

Colorizing technology highlights cancerous tissue

by Darren Murph posted Aug 20th 2008 at 10:23PM

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.

PEAK PlasmaBlade electrosurgery scalpel gets FDA approval

by Darren Murph posted Jul 25th 2008 at 3:01AM

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.

Complicated DIY project leads to Twittering Teddy Bear

by Darren Murph posted Jun 17th 2008 at 11:52PM

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.

UK woman edges closer to becoming bionic woman

by Darren Murph posted Jun 11th 2008 at 8:23AM

Eileen Brown doesn't have any full-fledged robotic phalanges or anything, but she is slowly but surely becoming what most would consider a bionic woman. Mrs. Brown has been suffering from rheumatoid arthritis since her 20s, and now that she's 49, countless operations have replaced every joint in her body with artificial alternatives save for her elbow and left hip -- the latter of which is set to be swapped out before the month's end. Currently, the determined dame lives with a lot of pain, but she refuses to let a few aches ruin her livelihood. In all honesty, the most amazing part of this isn't the ability of metal (enough to set off an airport detector) to hold a person together, it's the will to soldier on. Kudos, Eileen.

Robot surgeon removes brain tumor from Canadian, will see more patients soon

by Darren Murph posted May 19th 2008 at 1:16PM

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.

Duke inches toward autonomous robo-surgeons

by Ryan Block posted May 8th 2008 at 6:19AM

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.

PEAK PlasmaBlade electrosurgery scalpel is amazing, disgusting

by Nilay Patel posted May 8th 2008 at 5:02AM

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.
