1. A surgical instrument, comprising:
- an end effector, comprising;
a fastener cartridge comprising a plurality of fasteners removably stored therein; and
an anvil configured to deform said fasteners;
a closure drive configured to move said anvil relative to said fastener cartridge;
a firing drive configured to deploy said fasteners from said fastener cartridge; and
a rotatable shaft, comprising;
a first thread, wherein said closure drive is engageable with said first thread to move said anvil; and
a second thread, wherein said firing drive is engageable with said second thread to deploy said fasteners, and wherein said first thread at least partially overlaps said second thread.

Abstract
A surgical instrument can comprise an end effector, a first drive configured to perform a first end effector function, a second drive configured to perform a second end effector function, and a rotatable shaft. The rotatable shaft can comprise a first thread, wherein the first drive is engageable with the first thread to perform the first end effector function, and a second thread, wherein the second drive is engageable with the second thread to perform the second end effector function, and wherein the first thread is at least partially co-extensive with or overlaps the second thread.
