Is ‘pure’ robotic telesurgery nearing reality?

click to enlargeMoving beyond robot-assisted surgery (e.g. the well-accepted use of the daVinci system with prostate surgery), controlled by a surgeon present in the operating room, is telesurgery, where a remote surgeon uses a robot to fully perform surgery at a distant location. The Nicholson Center at Florida Hospital in Celebration, Florida, which specializes in training surgeons and technicians in leading (bleeding?-Ed.) edge techniques, is studying how internet latency (lag time to the non-techie) affects surgical effectiveness. Latency is defined in this case as “the amount of delay a surgeon can experience between the moment they perform an action to the moment video of the action being carried out at the surgery site reaches their eyes.” Their testing so far is that internet latency for surgery between hospitals has a threshold of 200-500 milliseconds before dexterity drops off dramatically (not desirable)–and that given the current state of the internet, it is achievable even at a mid-range distance tested (Florida to Texas). Making this a reality is highly desirable to military services worldwide, where expertise may be in, for example, Germany, and the casualty is in Afghanistan. It would also be a boon for organizations such as the Veterans Health Administration (VA) where resources are stretched thin, rural health and for relief agencies’ disaster recovery. ZDNet
