Colorizing technology highlights cancerous tissue

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.

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

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.

University of Washington's Raven to try surgery in simulated spacecraft

If you thought ASTRO and NextSat were the only two autonomous robots frolicking around in testing environments, Raven would certainly beg to differ, as NASA has recently announced that the University of Washington's mobile surgical robot will soon be off to tackle surgical tasks whilst underwater. The 12th NASA Extreme Environment Mission Operations test will see the mechanical MD pick up the tools in a simulated spacecraft submerged near Key Largo, Florida, where the "mission will test current technology for sending remote-controlled surgical robotic systems into space." Thanks to a combination of wired and wireless networks, a trio of seasoned veterans back in Seattle will be dictating the movements remotely, as the bot attempts to "suture a piece of rubber and move blocks from one spindle to another." Interestingly, there was no word on whether Raven was scheduled to pick up the night shift at Seattle Grace upon its return from the depths.

Surgical snakebots crawl down your throat

The Johns Hopkins University must employ some seriously bright folks, as researchers at the school are unveiling yet another marvel to benefit mankind, and this time their creation is headed for the nooks and crannies within your body that surgeons have difficulty reaching unassisted. Sure, the diminutive locales within your guts have been explored by robotic creatures before, but these "snake-like robots" could enable surgeons, operating in the narrow throat region in particular, to make "incisions and tie sutures with greater dexterity and precision." The invention consists of two thin rods tipped with "tentaclelike tools" capable of moving with six degrees of freedom; during surgery, the doctor would utilize a 3D visualization system to watch, control, and dictate the robotic tubes. Moreover, the snakes are crafted from nonferrous metals so it can be used around magnetic imaging equipment, and considering its ability to "make up 100 adjustments per second," nimbleness is in its nature. But if you're not exactly fond of such slithering creatures, you've still got time to escape, as researchers estimate that there's still about "five more years" of lab testing before we see Snakes on a Hospital Bed.

Haptic systems to bring feeling back to robotic instruments

We've heard some very intelligent humans suggest that computerized beings just might be a bit more adept at handling complicated tasks, but some things just require a little TLC from the human hand. While even the operating room wasn't safe from robotic takeover, researchers at The Johns Hopkins University are testing new ways to bring real feelings back to human doctors using robotic helpers in order to operate. Straight from a chapter in Trauma Center, the team is developing haptic technologies to provide close-to-real feedback to surgeons while handling robotic tools. One option undergoing testing is the attachment of "force sensors" to instruments, which are capable of conveying details about force, direction, and depth that are critical when performing incisions and other precise tasks. The alternative is to "create mathematical computer models" that represent tool movements, and consequently relay the haptic data back to the person in charge. While kinks continue to be worked out in the primary methods, researchers have developed an "interim" system that uses color-based sensors to inform doctors how much pressure is being applied (i.e. red for intense pressure, green for light), and the team plans on "refining the systems" to produce a more usable result in the near future.
