Tiny mechanical wrist gives new dexterity to needlescopic surgery

23 julio 2015

A mechanical wrist less than 1/16th of an inch thick — small enough to use in needlescopic surgery, the least invasive form of minimally invasive surgery — has been created by scientists. Needlescopic surgery, which uses surgical instruments shrunk to the diameter of a sewing needle, is the ultimate form of minimally invasive surgery. The needle-sized incisions it requires are so small that they can be sealed with surgical tape and usually heal without leaving a scar.img src=»http://feeds.feedburner.com/~r/sciencedaily/~4/z7bxLPzxcyY» height=»1″ width=»1″ alt=»»/
