The retraction mechanism (3) has been developed for use with a hand held surgical apparatus. An embodiment of the retraction mechanism includes a drive mechanism, a first pulley (50), a second pulley (9), and a firing drive (2). The drive mechanism is configured to be driven by a motor (5). The first pulley (50) is configured to rotate when the motor drives the drive mechanism. The second pulley (9) is movable 1o relative to the first pulley (50) between a proximal position and a distal position. The firing drive (2) is movable relative to the first pulley (50) between proximal and distal positions. In operation, the first pulley (50) rotates in a first direction in response to a distal translation of the firing drive (2) and wherein the firing drive (2) moves proximally upon rotation of the first pulley (50) in a second direction.1/20 C14. ccJ -::r C8 C-">； C
