One new robot is so easy to use that even med students can achieve proficiency with a few tries, according to Umamaheswar Duvvuri, director of head and neck surgery at the University of Pittsburgh Medical Center. The robot, a snake-like endoscope that can be directed into any shape through the relative orientations of its linkages, requires only one incision, reducing the number from several involved in typical laparoscopic procedures. Older, and more popular surgical robotic systems, such as the da Vinci Surgical System, are now being tested by physicians who are at controls more than 1,000 miles away. Probably a lot of the same misgivings that people have about autonomous cars apply here, too.
