Surgery in Space
The tiny, wheeled robots, which are about 3 inches tall and as wide as a lipstick case, can be slipped into small incisions and computer-controlled by surgeons in different locations. Some robots are equipped with cameras and lights and can send back images to surgeons. Others have surgical tools attached that can be controlled remotely.

What a marvellous invention, however I am guessing that this must be done in earth like gravity environment to prevent body particles including blood from spilling or should I say "floating". The other aspect is losing control of the robots and having them do things they should not.
