Tiny mechanical wrist gives new dexterity to needlescopic surgery

With the flick of a tiny mechanical wrist, a team of engineers and doctors at Vanderbilt Universitys Medical Engineering and Discovery Laboratory hope to give needlescopic surgery a whole new degree of dexterity. Needlescopic surgery, which uses surgical instruments shrunk to sinvasive surgery. The needlesized incisions it requires are so small that they can be sealed with surgical tape and usually heal without leaving a scar.
