An apparatus includes a first jaw () and a second jaw () that cooperate to clamp and staple tissue (). The second jaw includes a jaw body () and a distal tip () pivotable relative to the jaw body between a first discrete and a second discrete position. First and second openings () are both defined by one of the distal tip or a structure () located proximal to the distal tip. A projection () is defined by the other of the distal tip or the structure. The projection is positionable within the first opening () to releasably retain the distal tip in the first discrete position, and within the second opening () to releasably retain the distal tip in the second discrete position.

Surgical stapler with discretely positionable distal tip

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.

Method of surgical stapling

A stapling assembly for a surgical instrument includes a body extending along a longitudinal axis and having an upper deck, a plurality of pockets extending through the upper deck for receiving respective staples and arranged in at least two longitudinal rows, a plurality of staple drivers, and a staple driver actuator. The stapling assembly also includes a plurality of pocket extenders extending upwardly from the upper deck. Each pocket extender has a respective top surface. The stapling assembly further includes at least one upwardly-facing surface configured to contact an adhesive of an adjunct for securing the adjunct to the stapling assembly. The at least one upwardly-facing surface is disposed at least partially between at least a portion of the upper deck and the top surfaces of the plurality of pocket extenders, and spans laterally at least partially across at least two longitudinal rows of the plurality of pockets.

Surgical stapler cartridge having raised surface to promote buttress adhesion

A surgical stapler kit includes a surgical stapler having a body, a shaft, and an end effector. The kit includes a first staple cartridge having a first cartridge body and a first sled, and a second staple cartridge having a second cartridge body and a second sled. When the first staple cartridge is at least partially seated within a cartridge jaw with the first sled in a proximal undisplaced position, a knife drives the first sled distally to deploy staples from the first cartridge body. When the second staple cartridge is at least partially seated within the cartridge jaw with the second sled in a proximal undisplaced position, the knife advances distally into a lockout position before causing any staples to be deployed from the second cartridge body.
