摘要：
abstract of the disclosure differential locking systems for a surgical instrument that includes a surgical end effector that is powered by a rotary drive shaft assembly that is movable between a plurality of discrete axial positions. In various forms, at least one retention formation is provided on the rotary drive shaft assembly that corresponds to each one of the discrete axial position. at least one lock member is operably supported relative to rotary drive shaft assembly for retaining engagement with at least one of retention formations when the rotary drive shaft assembly is moved to discrete axial positions associated therewith. "differential locking arrangements for rotary drive surgical instruments" are presented differential locking systems for a surgical instrument including a surgical end actuator driven by a rotary drive rod assembly that is capable of move between a plurality of distinct axial positions. In various forms, at least one retainer formation is arranged in the rotary drive rod assembly corresponding to each of the distinct axial positions. at least one locking element is operably supported with respect to the rotary drive rod assembly for retentive engagement with at least one of the retaining formations when the rotary drive rod assembly is moved to the distinct axial positions associated therewith.abstract of the disclosure differential locking systems for a surgical instrument that includes a surgical end effector that is powered by a rotary drive shaft assembly that is movable between a plurality of discrete axial positions. in various forms, at least one retention formation is provided on the rotary drive shaft assembly that corresponds to each one of the discrete axial position. at least one lock member is operably supported relative to rotary drive shaft assembly for retaining engagement with the at least one of the retention formations when the rotary drive shaft assembly is moved to the discrete axial positions associated therewith.
