TISSUE RETRACTOR AND METHOD FOR USING THE RETRACTOR

摘要

A retractor (1) for manipulating an object includes a body (7, 8) having proximal and distal ends, a retraction device, and an actuation device. The retraction device has a head (5) connected to the distal end of the body (7,8), substantially rigid needles (4), and an actuator. The head has a pivot (60). The needles are pivotally connected to the head about the pivot. The actuator is operatively connected to the needles and is movably disposed within the head and/or the body. The actuation device (100) is connected to the proximal end of the body (7,8). The actuation device is operatively connected to the actuator (3) through the body and, upon actuation thereof, moves the actuator to selectively rotate the needles between a stowed position where the needles are stowed within the head (5) and a fully extended position where the needles are extended out of the head (5).
