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.

Surgical stapler with independently actuated drivers to provide varying staple heights

An apparatus includes a shaft assembly and an end effector. The shaft assembly includes an outer sheath and a staple driving mechanism. The end effector includes a staple deck, an anvil, a first staple driver, and a second staple driver. The staple deck defines a plurality of staple openings in at least one annular array. Each staple opening in the plurality of staple openings houses a staple. The anvil is configured to actuate relative to the staple deck to compress tissue between the staple deck and the anvil. The staple driving mechanism is configured to actuate the first staple driver to fire a first staple of the plurality of staples against the anvil. The staple driving mechanism is further configured to actuate the second staple driver independently of the first staple driver to fire a second staple of the plurality of staples against the anvil.

Powered circular stapler with reciprocating drive member to provide independent stapling and cutting of tissue

A surgical instrument includes an anvil and an elongate channel. The elongate channel includes a plurality of first electrical contacts and a plurality of electrical connectors comprising a plurality of second electrical contacts, wherein the electrical connectors are spring-biased such that a gap is maintained between the first electrical contacts and the second electrical contacts. The surgical instrument further includes a staple cartridge releasably attachable to the elongate channel, wherein the staple cartridge has a cartridge body comprising a plurality of staple cavities, a plurality of staples deployable from the staple cavities into the tissue, and a plurality of third electrical contacts, wherein the attachment of the staple cartridge to the elongate channel moves the electrical connectors causing the second electrical contacts to bridge the gap and become electrically coupled to the first electrical contacts.
