Abstract
A surgical instrument comprising a first jaw, a second jaw rotatable relative to the first jaw about a pivot, and a firing system comprising a firing member is disclosed. The firing member is movable between a proximal unfired position and a distal fired position. When the firing member is in its proximal unfired position, the pivot is nested within a recess defined in the firing member. In at least one instance, the firing member comprises a tissue cutting knife. In various instances, the firing member comprises a first cam slideably positioned within the first jaw and a second cam slideably positioned within the second jaw. In at least one such instance, the second cam is contained within a chamber defined in the second jaw when the firing member is in its proximal unfired position.
