A retraction mechanism allows the full distal retraction of the firing drive from various positions. The retraction mechanism has been developed for use with a hand held surgical apparatus. An embodiment of the retraction mechanism includes a drive member, a first pulley, a second pulley, and a firing drive. The drive mechanism is configured to be driven by a motor. The first pulley is configured to rotate when the motor drives the drive mechanism. The second pulley is movable relative to the first pulley between a proximal position and a distal position. The firing drive is movable relative to the first pulley between proximal and distal positions. In operation, the first pulley rotates in a first direction in response to a distal translation of the firing drive and wherein the firing drive moves proximally upon rotation of the first pulley in a second direction.
What it is claimed is: 1. A retraction mechanism for use with a hand held surgical apparatus, comprising:a drive mechanism configured to be driven by a motor;a first pulley operatively associated with the drive mechanism, wherein the first pulley is configured to rotate when the drive mechanism is d
What it is claimed is: 1. A retraction mechanism for use with a hand held surgical apparatus, comprising:a drive mechanism configured to be driven by a motor;a first pulley operatively associated with the drive mechanism, wherein the first pulley is configured to rotate when the drive mechanism is driven;a second pulley disposed in mechanical cooperation with the first pulley, the second pulley being movable relative to the first pulley between at least proximal position and a distal position;a firing drive operatively coupled to the first pulley and the second pulley, the firing drive being movable relative to the first pulley between at least proximal and distal positions, wherein the first pulley rotates in a first direction in response to a distal translation of the firing drive and wherein the firing drive moves proximally upon rotation of the first pulley in a second direction; anda first sensor adapted to detect the second pulley when positioned in the distal position and a second sensor adapted to detect the firing drive when positioned in the proximal position.
