[Construction] A surgical instrument 1 of this invention comprises; an elongate main body 2, a leading end part 3 disposed on the leading end side of the main body 2 of the instrument, a manipulating part 9 disposed on the basal end side of the main body 2, and an elongate transmitting member for connecting the leading end part 3 with the manipulating part 9. Surgically operating means 4 for producing an open-close motion or a rotary motion based on a rotation of a movable nipping piece 42 relative to a stationary nipping piece 41 and locking means for fixing an opening angle of the movable nipping piece 42 are provided in the leading end part 3. An operation of rotating a movable handle 94 of the manipulating part 9 gives rise to an open-close motion of surgically operating means 4. The surgical instrument 1 further comprises unlocking means actuated by an unlocking lever 83. The main body 2 of the instrument is allowed to bend or curve in curving part 23 hereof. n [Effect] This surgical instrument allows the surgically operating means to fix the posture thereof infallibly and enjoys outstanding operational efficiency. |
