The last 2 minutes of this video, from 17 minutes or so onward, is lovely. Catherine Mohr gives a brief history of surgery and the latest equipment and techniques. As TED advertises, it's not for the squeamish, though I didn't find it squeamish at all. However, listen to what Catherine says about why she does not want to make it less frightening for you to face surgery. That idea was beautiful. Great way to finish a talk, in a way we could all appreciate, even if we don't care about surgery.

Surgeon and inventor Catherine Mohr tours the history of surgery (and its pre-painkiller, pre-antiseptic past), then demos some of the newest tools for surgery through tiny incisions, performed using nimble robot hands. Fascinating -- but not for the squeamish.

Catherine Mohr works on surgical robots and robotic surgical procedures, using robots to make surgery safer -- and to go places where human wrists and eyes simply can't.
