1. A surgical stapling system, comprising:

  • a housing comprising a first rotary input disc and a second rotary input disc configured to be driven by a rotary motion generator;

    an elongate shaft extending from said housing, wherein said elongate shaft defines a longitudinal axis;

    an end effector, comprising;

    a jaw configured to support a staple cartridge; and

    an anvil rotatable relative to said jaw between an open position and a clamped position, wherein said anvil comprises a cam surface;

    a closure cam operably coupled with said first rotary input disc, wherein said closure cam is configured to move longitudinally to engage said cam surface and transmit a clamping motion to said anvil to move said anvil toward said clamped position in response to an input motion from said first rotary input disc; and

    an opening member configured to move longitudinally to apply an opening force to said anvil at a location other than said cam surface to move said anvil toward said open position in response to an input motion from said second rotary input disc.
