A surgical stapling instrument includes an anvil defining a plurality of staple forming pockets, and a stapling head assembly, and a retracting assembly. The stapling head assembly includes a body, a coupling member capable of actuating the anvil, a deck surface, a staple driver assembly, and a knife member. The staple driver assembly actuates through a first firing stroke and a second firing stroke. In the first firing stroke, the staple driver assembly drives a plurality of staples against the staple forming pockets. In the second firing stroke, the staple driver actuates distally past the deck surface. The knife member includes a cutting edge that can sever tissue during the first firing stroke while remaining in a retracted position that is proximal relative to the staple deck surface during the second firing stroke. The retracting assembly can drive the knife member into the retracted position during the first firing stroke.

A surgical end effector comprising a cartridge jaw is disclosed. The cartridge jaw comprises a proximal channel portion extending along a longitudinal axis, and a distal portion movable relative to the proximal channel portion between an open position and a closed position. The surgical end effector further comprising a staple cartridge removably seated in the cartridge jaw, wherein the staple cartridge is configured to slide along the longitudinal axis into the proximal channel portion of the cartridge jaw when the distal portion is in the open position.

Staple cartridge replacement

A surgical instrument that comprises an elongate shaft assembly that defines a shaft axis. A surgical end effector is pivotally coupled to the elongate shaft assembly for selective pivotal travel relative thereto about an articulation axis that is laterally offset from the shaft axis and extends transversely relative thereto. An end effector driver link is operably coupled to the surgical end effector and an articulation driver that is supported for longitudinal travel in distal and proximal directions upon application of articulation motions thereto. A flexible de-articulation member is coupled to the elongate shaft assembly and the surgical end effector to apply de-articulation motions to the surgical end effector.

A surgical stapling instrument comprising an elongate shaft assembly that defines a shaft axis and includes a surgical end effector that is operably coupled thereto by an articulation joint. The surgical instrument includes a longitudinally movable flexible firing beam that is configured to flexibly traverse the articulation joint and be selectively axially movable from a starting position to an ending position. A middle support member is movably coupled to the elongate shaft assembly and a portion of the surgical end effector. A proximal support link is located proximal to the middle support member and is configured to provide lateral support to a proximal portion of the flexible firing beam traversing the articulation joint. A distal support link is located distal to the middle support member and is configured to provide lateral support to a distal portion of the flexible support beam traversing the articulation joint.
