Abstract

A surgical instrument can comprise a handle, a motor, and a shaft extending from the handle. The handle and/or the shaft can define a longitudinal axis. The surgical instrument can further comprise a fastener cartridge comprising a plurality of fasteners removably stored therein, an anvil configured to deform the fasteners, a closure drive configured to move the anvil toward and away from the fastener cartridge which is rotatable about the longitudinal axis, and a firing drive configured to deploy the fasteners from the fastener cartridge which is rotatable about the longitudinal axis. The surgical instrument can further comprise a transmission comprising a first operating configuration which connects the motor to the closure drive and a second operating configuration which connects the motor to the firing drive.
