Abstract
A surgical instrument comprising a housing, an elongate shaft, an end effector for performing a surgical operation, a firing drive, an advancement assembly, and a retraction assembly is disclosed. The end effector operably supports a firing member that is movable from a proximal position to a fired position during a firing stroke in response to a longitudinal firing motion applied thereto. The firing drive is configured to transmit the longitudinal firing motion to the firing member upon actuation of a firing control actuator. The advancement assembly is supported by the housing and configured to transmit a rotary motion which is exclusively dedicated to the advancement of the firing member through the firing stroke. The retraction assembly is configured for manual rotary actuation about a longitudinal retraction axis. The retraction assembly is exclusively dedicated to the retraction of the firing member from the fired position to the proximal position.
