1. A surgical instrument, comprising:
an elongate shaft assembly comprising a distal end and a proximal end and defining a shaft axis;
a surgical end effector, comprising:
an end effector frame assembly operably coupled to said elongate shaft assembly for selective rotation relative to said elongate shaft assembly about said shaft axis;
a first jaw pivotally supported on said end effector frame assembly; and
a second jaw pivotally supported relative to said first jaw, wherein said first jaw and said second jaw are pivotable relative to each other between an open position and a closed position when an axial control motion is applied to at least one of said first jaw and said second jaw, and wherein said surgical instrument further comprises:
a lock member movably supported by said distal end of said elongate shaft assembly, wherein said lock member is movable between an unlocked position in which said end effector frame assembly is rotatable about said shaft axis and a locked position in which said lock member engages said end effector frame assembly to prevent said end effector frame assembly from rotating about said shaft axis;
a lock actuator operably interfacing with said lock member to move said lock member between said locked position and said unlocked position; and
a drive member operably interfacing with said end effector frame assembly and said first jaw and said second jaw, wherein said drive member is configured to apply said axial control motion to at least one of said first jaw and said second jaw to move said first jaw and said second jaw between said open position and said closed position, and wherein said drive member is further configured to apply a rotary motion to said end effector frame assembly to rotate said end effector frame assembly relative to said elongate shaft assembly about said shaft axis when said lock member is in said unlocked position.
