Surgical robot could sew you up better than a doctor
Surgical teams aren't fond of robots that could replace them (just ask Johnson & Johnson), but that doesn't mean they're completely against mechanical helpers. Children's National Medical Center and Johns Hopkins University recently tested a Smart Tissue Autonomous Robot (STAR) arm during experimental bowel surgery on anesthetized pigs. The machine only handled suturing by itself, but excelled at that job -- it sewed more consistently than veteran doctors and even other robotic assistants. Its edge comes from using a depth-savvy light field camera to find fluorescent markers placed inside the tissue, helping it spot folds that would normally stay hidden.
