Abstract
A retraction mechanism has been developed for use with a hand held surgical apparatus. The retraction mechanism includes a motor, a first speed reducing mechanism, a clutch mechanism incorporating a second speed reducing mechanism, and a shaft. The first speed reducing mechanism is configured to be driven by a motor. The second speed reducing mechanism has a locked state and an unlocked state. In addition, the clutch mechanism is disposed in mechanical cooperation with the first speed reducing mechanism. The shaft is configured to rotate upon activation of the motor the second speed reducing mechanism is in the locked state. The rotation of the shaft retracts a firing drive of the hand held surgical apparatus.
