Surgical stapler with independently actuated drivers to provide different staple heights

摘要

The device includes a body, a shaft assembly, and an end effector. The shaft assembly includes an outer sheath and an electric drive mechanism. The body assembly is configured to actuate the drive mechanism. End effectors include a staple deck, anvil, a first staple driver, and a second staple driver. The first staple driver is configured to fire the staples of the first annular array of the plurality of staples against the anvil, deforming the staples of the first annular array at the height of the first compression staples. Has been done. The second staple driver fires the staples of the second annular array of the plurality of staples against the anvil, and is independent of the first staple driver and is second at the second compression staple height. It is configured to deform the staples of the annular array of. The height of the first compression staple and the height of the second compression staple are different.
