摘要： A surgical stapling instrument comprising an articulatable end effector including a staple cartridge is disclosed. The stapling instrument further comprises an articulation drive configured to articulate the end effector and a staple firing drive configured to fire the staples from the staple cartridge during a staple firing stroke. The articulation drive is selectively engageable with the staple firing drive to articulate the end effector and decoupled from the staple firing drive during the staple firing stroke. The stapling instrument further comprises a control system that is configured to compensate for the net displacement of the staple firing drive that occurs when articulating the end effector.

摘要： An adjunct configured for use with an end effector of a surgical stapler includes a tissue-effecting portion comprising a first material, and at least one movable attachment feature coupled to the tissue-effecting portion and comprising a second material different from the first material. The at least one movable attachment feature is configured to releasably attach the tissue-effecting portion to a stapling surface of the end effector. The tissue-effecting portion is configured to contact tissue clamped by the end effector during closure thereof. The tissue-effecting portion is further configured to be pierced and captured by staples ejected from the end effector into the clamped tissue and thereby reinforce the engagement between the ejected staples and the clamped tissue.

摘要： A surgical stapling instrument comprising a tissue cutting knife movable through a staple cartridge to perform a staple firing stroke is disclosed. The stapling instrument further comprises a lockout system configured to prevent the tissue cutting knife from being moved through the staple firing stroke if the staple cartridge is missing from the stapling instrument and/or if the staple cartridge has been previously fired. The lockout system comprises a flexible spring that acts on the bottom of the tissue cutting knife at the initiation of the staple firing stroke to push the tissue cutting knife into a lockout recess if the staple cartridge is missing or has been previously fired.

摘要： A surgical instrument comprising an articulatable end effector and an articulation control system is disclosed. The articulation control system comprises actuators that, when actuated, cause the end effector to articulate in predetermined directions. When the end effector is rotated downwardly, the articulation control system flips, or switches, the response to the inputs from the actuators.

摘要： A method of operating a surgical instrument includes clamping tissue with a surgical instrument end effector and actuating the end effector to drive staples into the clamped tissue, including a first longitudinal row having at least one first formed staple with a first formed shape in which the first legs are aligned laterally with each other and with the first crown; a second longitudinal row having at least one second formed staple with a second formed shape in which each second leg is skewed laterally away from the second crown at a first angle; and a third longitudinal row of third formed staples having at least one third formed staple with a third formed shape in which each third leg is skewed laterally away from the third crown at a second angle.

摘要： An apparatus includes a jaw body, an anvil surface defined by the jaw body, and an elongate slot extending through the anvil surface and along a longitudinal axis of the jaw body. The apparatus further includes a first longitudinal row of staple forming pockets disposed on the anvil surface and configured to form a plurality of first staples such that first legs of each formed first staple are laterally aligned with each other. The apparatus also includes a second longitudinal row of staple forming pockets disposed on the anvil surface laterally outwardly of the first longitudinal row of staple forming pockets relative to the longitudinal axis, and configured to form a plurality of second staples such that second legs of each formed second staple skew laterally away from a second crown of the respective formed second staple.

摘要： An apparatus includes a first jaw (16) and a second jaw (618, 718, 900) that cooperate to clamp and staple tissue (90). The second jaw includes a jaw body (620, 720, 902) and a distal tip (619, 719, 906) pivotable relative to the jaw body between a first discrete and a second discrete position. First and second openings (663, 784, 785, 932, 934) are both defined by one of the distal tip or a structure (621, 920) located proximal to the distal tip. A projection (637, 781, 918) is defined by the other of the distal tip or the structure. The projection is positionable within the first opening (663, 785, 932) to releasably retain the distal tip in the first discrete position, and within the second opening (663, 784, 934) to releasably retain the distal tip in the second discrete position.

摘要： A surgical stapling instrument includes an anvil defining a plurality of staple forming pockets and a stapling head assembly configured to drive a plurality of staples against the staple forming pockets of the anvil. The stapling head assembly comprises a coupling member configured to actuate the anvil relative to the stapling head assembly, a firing assembly configured to drive the plurality of staples against the staple forming pockets of the anvil, and a deck member. The deck member includes a deck surface extending radially between an inner circular edge and an outer circular edge, and a plurality of staple openings extending through the deck surface. The plurality of staple openings define at least one cross shape.
