Good news! Tiny robots designed by University of Nebraska researchers may   50     doctors on Earth to help perform surgery on patients in space.

The tiny, wheeled robots, which are about 3 inches tall and as wide a lipstick case, can be slipped into small incisions ( 切口 ) and computer-controlled by surgeons in different   51   . Some robots are equipped with    52    and lights and can send images back to surgeons and others have surgical tools attached that can be controlled    53   .

Eventually, Oleynikov said, “ The tiny robots may enable surgeons to work without ever __63__their hands in patients’ bodies. That is the    64   . It is getting easier and easier. We can do even more with these devices.”
