Claim 11:
12. A surgical instrument system, comprising:
a housing;
a rotatable input system configured to receive rotary motions from a motor; and
an end effector, comprising:
a first jaw;
a second jaw;
a first nut comprising a tissue cutting surface, wherein said first nut is in threaded engagement with a threaded section of said rotatable input system; and
a second nut in threaded engagement with said rotatable input system such that the rotation of said rotatable input system in a first direction causes said second nut to move said first jaw from an open position to a closed position, wherein said second nut remains in threaded engagement with said rotatable input system while continued rotation of said rotatable input system in said first direction drives said first nut distally through a firing stroke and drives said second nut distally from a clamped position corresponding to the closed position of said first jaw to an ending position during the firing stroke.
