    摘要： 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.

    摘要： 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.

    摘要： A surgical instrument includes an end effector, a firing member movable distally to effect a firing motion at the end effector, wherein the firing member comprises a cam slot, and a lockout pawl. The lockout pawl has a cam feature receivable in the cam slot, wherein the cam slot is configured to guide the cam feature to cause a rotation of the lockout pawl between a first position where the lockout pawl permits the distal movement of the firing member, and a second position where the lockout pawl prevents the distal movement of the firing member.

    摘要： A surgical stapling instrument includes an anvil defining a plurality of staple forming pockets and a stapling head assembly. The stapling head assembly includes a body, a coupling member capable of actuating the anvil relative to the body, a staple deck defining a plurality of staple openings, and a firing assembly capable of driving a plurality of staples against the staple forming pockets of the anvil. The firing assembly includes a proximal driving body and an array of discrete staple driving segments positioned distal to the proximal driving body. The proximal driving body is slidably housed within the body. The staple driving segments each have a free proximal end. The proximal driving body is capable of simultaneously actuating the array of staple driving segments to drive the plurality of staples against the staple forming pockets of the anvil.
