Telesurgery tests highlight the limits of the Internet
Telesurgery has the potential to bring surgeons in contact with patients anywhere, any time. In a remote robotic-assisted surgery, a doctor would be able to guide a mechanical device at a far away location to perform the procedure. The use of robotics in surgeries has been successful, as long as the operator and the device are in the same OR. But putting distance between the two has been problematic. The whole process relies on a strong network or Internet for connectivity, which invariably results in some amount of latency. Even the slightest lag can have serious implications. With a $4.9 million grant from the U.S. Department of Defense, the Florida Hospital Nicholson Center has completed a series of tests that reveal improvements in bandwidth technology are making telesurgery safer.
Google teams with Johnson & Johnson for robotic-assisted surgery
Google's mysterious facility, Google X, is churning out next level technologies -- a self-driving car, delivery drones and Internet balloons. Its Life Sciences division is now teaming up with Ethicon, one of Johnson & Johnson's medical device companies, to develop robotic-assisted surgeries. "Through this collaboration, we are looking to provide surgeons with a technologically advanced system that would help them make the best, most informed decisions," Gary Pruden, Worldwide Chairman, Global Surgery Group at Johnson & Johnson told Engadget. "The surgeon remains the ultimate decision maker, but they will have even more support with precision movements and data-enhanced decision making tools."
University of Washington students hack Kinect to aid in robotic surgery
We're sure that a time will come when we're slightly less amazed by Kinect hacks but, right now, we're still just seeing one more impressive than the last -- and we're certainly OK with that. This latest comes to us from a group of students at the University of Washington, who had the bright idea to pair Microsoft's device with some of the robotic surgery projects currently being developed by the university's BioRobotics Lab. That combo isn't quite the sentient, Kinect-enhanced robo-surgeon you may have feared, though. The students are actually using Kinect to provide force-feedback to the actual, human surgeons controlling the robotic equipment -- something that would have been a $50,000 proposition without Kinect. As you might expect, however, the Kinect-based system isn't quite ready to be used for actual surgery as it is -- while it gets the job done as a proof of concept, the students note that the sensors will need to be scaled down, and the resolution improved in order to be deemed suitable for surgical use.
New robotic system could let surgeons operate on a beating heart
It may not have been put into practice just yet, but it looks like a new robotic-assisted system could one day let surgeons use a surgical robot (like Da Vinci system pictured at left) to operate on a beating human heart. That impressive development comes courtesy of a group of researchers at France's Montpellier Laboratory of Informatics, Robotics, and Microelectronics, and centers on a new 3D modeling system that can track the motion of the heart's surface as it beats. It can even apparently adjust for things like movement of the patient's chest wall during breathing, and predict the movements in a single step (unlike previous attempts that resulted in a delay). When paired with a robotic arm, the system would effectively let surgeons operate on a heart as if it were completely still. In addition to being generally amazing, the system could also potentially open up a number of new possibilities for heart surgery, not the least of which is the ability to operate on patients for whom the risks of surgery have previously outweighed the benefits.
Students whip up Operation-playing robots
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.
