摘要：
A surgical instrument. In one form, the surgical instrument comprises a first jaw and a second jaw that is movably supported relative to the first jaw for selective movement between open and closed positions relative to the first jaw. A firing drive shaft is rotatably supported in one of the first and second jaws. A firing member operably interfaces with the firing drive shaft for selective axial travel in response to rotation of the firing drive shaft. The surgical instrument further comprises a distal power shaft that is separate and distinct from the firing drive shaft and is configured for selective operable engagement with the firing drive shaft. A closure member is supported for axial travel on a proximal end portion of the first jaw and is configured for selective threaded engagement with a portion of the distal power shaft.
