| 摘要 |
A medical instrument for use in a laparoscopy comprises a long, slender body having opposite ends which are distal and proximal relative to a person holding the instrument, a pair of tips adjacent the distal end of the body, at least one of said pair of tips being movable with respect to the other of said tips, and a tip actuation mechanism movably connected at the proximal end of the body for actuating movement of the at least one movable tip. The tip actuation mechanism is longitudinally aligned with the pair of tips and coplanar therewith whereby operator-controlled motion of the tip actuation mechanism in a plane extending through the longitudinal axis of the body effects motion of the at least one movable tip with respect to the other tip in the same plane. The distal end of the body of the instrument is adapted to be inserted into a patient during the laparoscopy.
