The retraction mechanism (3) includes a motor (6), a first speed reducing 5 mechanism (8), a clutch mechanism (11) incorporating a second speed reducing mechanism, and a shaft (46). The first speed reducing mechanism (8) is configured to be driven by a motor (6). The second speed reducing mechanism (11) has a locked state and an unlocked state. In addition, the clutch mechanism (11) is disposed in mechanical cooperation with the first speed reducing mechanism (8). The shaft (46) is configured to 10 rotate upon activation of the motor (6) the second speed reducing mechanism (11) is in the locked state. The rotation of the shaft (46) retracts a firing drive of the hand held surgical apparatus (10).1/8 cv cli C4 to C , CD 00 C 4 C.3 cli 00 Lo
