Claim 0:
1. A surgical system, comprising:
a shaft defining a shaft axis;
a first rotary output shaft operably supported by a housing;
a rotary drive screw extending along said shaft axis and actuatable by said first rotary output shaft;
a second rotary output shaft operably supported by said housing and actuatable independently of said first rotary output shaft;
a surgical end effector, comprising:
a first jaw and a second jaw, wherein one of said first jaw and said second jaw is movable relative to the other of said first jaw and said second jaw between open and closed positions upon application of jaw control motions thereto by said first rotary output shaft; and
a distal firing beam head axially movable between a starting position and an ending position within said first jaw and said second jaw, said distal firing beam head configured to slidably engage each of said first jaw and said second jaw upon application of a firing motion thereto, wherein said surgical system further comprises:

an elongate shaft assembly operably coupled to said surgical end effector, said elongate shaft assembly comprising a firing shaft operably interfacing with said distal firing beam head to apply said firing motion thereto, said firing shaft defining a firing shaft axis that extends along said shaft axis; and
a rotary firing drive shaft extending along said shaft axis and actuatable by said second rotary output shaft, wherein said rotary firing drive shaft is operably coupled to said firing shaft, wherein said second rotary output shaft rotates about a rotary output axis such that rotation of said second rotary output shaft about said rotary output axis imparts a firing motion to said distal firing beam head to thereby axially move said distal firing beam head within said first jaw and said second jaw.
