1. A surgical instrument, comprising:

  • an elongate shaft assembly defining a shaft axis;

    a surgical end effector comprising a distal end and a proximal end, said proximal end being pivotally coupled to said elongate shaft assembly for selective pivotal travel about an articulation axis that extends transversely relative to said shaft axis, said surgical end effector selectively pivotable about said articulation axis from an unarticulated position wherein said distal end of said surgical end effector is located an unarticulated distance from said articulation axis to articulated positions wherein said distal end of said surgical end effector is located a corresponding articulated distance from said articulation axis that is less than said unarticulated distance; and

    means for selectively applying articulation motions to said surgical end effector, wherein said means for selectively applying comprises a rotary gear in meshing engagement with said surgical end effector.
