This invention is an instrument for manipulating anatomical tissue, and a method of using the instrument. A barrel (32) has two drivers (40, 40') therein which can be manipulated from a proximal end of the barrel (32). The end effectors (50A, 50B, 50A', 50B') of each driver (40, 40') are offset from a shaft (44, 44') by a transverse arm (51A, 51B, 51A', 51B'). In an insertion position, the end effectors (50A, 50B, 50A', 50B') are confined within the diametrical dimension of the barrel (32) at a distal end thereof. After insertion, the end effectors (50A, 50B, 50A', 50B') can be manipulated by rotationally or arcuately moving the shafts (44, 44') to extend beyond the diametrical dimension of the barrel (32) to provide a large working span in which a tissue procedure can be accomplished. |
