Abstract

An apparatus includes a body assembly, a shaft assembly, and an end effector. The shaft assembly includes an outer sheath and a motorized driving mechanism. The body assembly is configured to actuate the driving mechanism. The end effector includes a staple deck, an anvil, a first staple driver, and a second staple driver. The first staple driver is configured to fire a first annular array of staples of the plurality of staples against the anvil to deform the first annular array of staples at a first compressed staple height. The second staple driver is configured to fire a second annular array of staples of the plurality of staples against the anvil to deform the second annular array of staples at a second compressed staple height independent of the first staple driver. The first compressed staple height and the second compressed staple height are different.
