SURGICAL INSTRUMENT WITH ARCUATELY MOVABLE OFFSET END EFFECTORS AND METHOD OF USING THE SAME

摘要

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