    摘要： In various embodiments, a surgical stapler is provided that may comprise a body, a stapling head operably coupled to the body, an anvil movably supported relative to the stapling head for selective travel toward and away from the stapling head, and an anvil adjustment shaft supported by the body for selectively adjusting a position of the anvil relative to the stapling head. The adjustment shaft and/or the body may be configured to establish at least one predetermined staple forming height between the anvil and the stapling head irrespective of adjustment shaft rotation. Additionally, the adjustment shaft and/or the body may be configured to provide tactile feedback to a user rotating the anvil adjustment shaft, thereby providing the user of an indication of when an appropriate staple forming height has been reached. Various integrations of components described herein may also reduce the part count required for a surgical stapler, thereby reducing assembly time and manufacturing cost.

    摘要： In various embodiments, a surgical stapling head is provided that may comprise a staple cartridge for supporting one or more staples, a core movable relative to the staple cartridge, at least one staple driver extending from the core, and a casing configured to at least partially hold the staple cartridge and movably receive the core and the staple driver(s). The casing may further comprise at least one retention member that is configured to move from a first position to a second position when sufficient external force is applied to the retention member, such as that provided by a shaft of a surgical stapler during insertion of the stapling head assembly into the shaft. When the retention member(s) are at the second position, the staple driver(s) may be prevented from driving staples from the staple cartridge, thereby providing a firing lockout feature to the stapling head assembly during insertion into at least a portion of a surgical stapler.

    摘要： A surgical instrument includes a handle portion, a shaft housing a firing bar, an end effector comprising an anvil, a lower jaw, and a stapling and severing assembly responsive to a longitudinal closing motion produced by the handle portion and the shaft. The lower jaw is configured to receive a removable cartridge. The cartridge includes a housing, a plurality of staples disposed in the housing, a deck disposed over the plurality of staples, and a fastener insert tip including a plurality of hooks. The deck defines apertures, with each aperture being substantially disposed over each staple. The instrument includes a fastener insert including hooks, and the fastener insert is removably received in the anvil. A buttress is attached to one or both of the anvil and the cartridge via the hooks.
