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   .

   “ We think this is going to    54    open surgery.” Dr. Dmitry Oleynikov said at a news conference. Oleynikov is a    55    in computer-assisted surgery at the University of Nebraska Medical Center in Omaha.

   Officials hope that NASA will teach    56    to use the robots soon enough    57   

surgeries could one day be performed in space.

   The camera-carrying robots can provide    58    of affected areas and the ones with surgical tools will be able to operate inside the body in ways surgeons’ hands can’t. The views from the camera-carrying robots are    59    than the naked eye, because they    60    back color images that are magnified. Because several robots can be inserted through one incision, they could reduce the amount and    61    of cuts needed for surgery, which would decrease recovery time. This is particularly    62    to those patients who have been weakened by long illness.

   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.”
