1. A surgical system comprising:

  • a rotary output member operably supported by a housing;

    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; and

    a firing member axially movable between a starting position and an ending position within said first jaw and said second jaw, said firing member configured to slidably engage each of said first jaw and said second jaw upon application of a firing motion thereto to affirmatively orient said first jaw and said second jaw relative to each other at a desired spacing orientation and wherein said surgical system further comprises;

    an elongate shaft assembly operably coupled to said surgical end effector and defining a longitudinal tool axis, said elongate shaft assembly comprising a firing shaft operably interfacing with said firing member to apply said firing motion thereto, said firing shaft defining a firing shaft axis that is parallel to said longitudinal tool axis; and

    a firing drive member operably coupled to said firing shaft and is configured to interface with said rotary output member, wherein said rotary output member rotates about a first rotary output axis that is transverse to said firing shaft axis such that rotation of said rotary output member about said first rotary output axis imparts a firing motion to said firing member to thereby axially move said firing member within said first jaw and said second jaw, and wherein said firing shaft is rotatable such that rotation of said rotary output member about said first rotary output axis rotates said firing shaft about said firing shaft axis to thereby axially drive said firing member within said first jaw and said second jaw.
