Abstract

A surgical severing and stapling instrument, suitable for laparoscopic and endoscopic clinical procedures, clamps tissue within an end effector of an elongate channel pivotally opposed by an anvil. Various embodiments are configured to be operably attached to a robotic system to receive actuation/control motions therefrom.

First claim

1 - 20 . (canceled)

21 . A surgical instrument, comprising:
a channel member configured to support a staple cartridge; an anvil coupled to the channel member; a rotatable drive screw; a firing member configured to be advanced by the rotatable drive screw; a sled member configured to be advanced to eject staples from the staple cartridge to form a staple pattern during a firing cycle, wherein the sled member is positioned at least partially outside the staple pattern at a completion of the firing cycle; an elongate shaft assembly coupled to the channel member; a housing coupled to the elongate shaft assembly, wherein the housing comprises more than two rotatable elements; and a closure system, comprising:
a linear camming member coupled to the anvil; and
a rotatable member coupled to the linear camming member, wherein:
a rotation of the rotatable member in a first direction operates to urge the anvil into a close approximation to the channel member; and
a rotation of the rotatable member in a second direction operates to release a clamp load on the anvil and move the anvil to an unclamped position.

22 . The surgical instrument of claim 21 , wherein the channel member comprises the staple cartridge.

23 . The surgical instrument of claim 22 , wherein the staple cartridge comprises a replaceable staple cartridge.

22 . A surgical instrument, comprising:
a cartridge channel; a staple cartridge comprising a plurality of staples removably stored in the staple cartridge, wherein the staples define a staple zone; an anvil movable relative to the cartridge channel; a rotatable drive screw; a firing member actuatable by the rotatable drive screw; a sled member actuatable through a firing stroke to eject the staples from the staple cartridge, wherein the sled member is actuatable between an unfired position and fired position, wherein the sled member extends beyond the staple zone in the fired position; an elongate shaft assembly; a housing coupled to the elongate shaft assembly, wherein the housing comprises more than two rotatable elements; and a closure system, comprising:
a linear camming member coupled to the anvil; and
a rotatable member coupled to the linear camming member, wherein:
a rotation of the rotatable member in a first direction moves the anvil into a clamped position; and
a rotation of the rotatable member in a second direction moves the anvil into an unclamped position.

25 . The surgical instrument of claim 24 , wherein the staple cartridge comprises a replaceable staple cartridge.
