<P>PROBLEM TO BE SOLVED: To provide a surgical staple fastener with a retraction mechanism with clutch-less drive. <P>SOLUTION: The retraction mechanism 3 is developed for use with a hand held surgical apparatus. The retraction mechanism includes a drive member configured to be driven by a motor 5; a first pulley 9 configured to rotate when the motor drives the drive mechanism; a second pulley 50 disposed so as to mechanical operate relative to the first pulley 9 and is at least movable between a proximal position and a distal position relative to the first pulley 9; and a firing drive operably coupled to the first and second pulleys. <P>COPYRIGHT: (C)2010,JPO&INPIT |
