A surgical instrument includes a first and second jaw, a firing assembly, a first buttress assembly, and a second buttress assembly. The first and second jaw actuate relative to each other between an open and closed position to grasp tissue. The second jaw includes a fastening assembly having a deck defining a plurality of openings and a plurality of fasteners housed within the openings. The firing assembly drives the plurality of fasteners out of the plurality of openings against a plurality of fastening forming features of the first jaw. The first buttress assembly and the second buttress assembly are associated with the first and second jaw, respectively. The first buttress assembly includes a first material and a first thickness. The second buttress assembly includes a second material and a second thickness. The first material and the second material differ in rigidity. The first thickness and the second thickness are different.

Tissue cushion adjuncts for surgical stapler end effector

A surgical instrument includes a first and second jaw actuatable between an open and closed position, a buttress assembly having a compressible material, and a fastener assembly associated with the second jaw. The fastener assembly and the buttress assembly may cooperatively grasp tissue while the first and second jaws are in the closed position. The fastener assembly includes a deck defining a plurality of openings and a plurality of fasteners each housed within a respective opening of the plurality of openings. Each fastener can actuate out of the respective opening and into the buttress assembly. Each fastener includes a first leg having a piercing tip, and an attachment feature associated with the first leg. The attachment feature can engage the buttress assembly to couple the first leg with the buttress assembly without bending a portion of the first leg associated with the piercing tip.

Surgical stapler features for stapling variable thickness tissue

An apparatus includes a stapling assembly and an anvil. The stapling assembly includes first and second staples. Each of the first and second staples include first legs. The anvil together with the stapling assembly is configured to clamp tissue of a patient. The anvil includes a first staple forming pocket that is configured to transition the first legs of the first and second staples from a non-deformed state to a deformed state with the same firing stroke.

Staple and staple-forming pocket arrangements for surgical staplers

A surgical stapler includes a first stapler half including an anvil surface having a plurality of staple forming pockets, and a second stapler half configured to releasably couple with the first stapler half. The second stapler half is operable to deploy staples toward the anvil surface. The stapler also includes a projection positioned on one of the stapler halves and extending laterally relative to a longitudinal axis of the stapler. The stapler halves are configured to pivot relative to each other about the projection. The stapler further includes a locking member positioned on the other of the stapler halves. The locking member is configured to translate along the longitudinal axis of the stapler between a locked state in which the locking member selectively captures the projection and an unlocked state in which the locking member selectively releases the projection. The locking member is biased proximally toward the locked state.

Pin trap mechanism for surgical linear cutter

A buttress applier cartridge configured to interface with an end effector of a surgical stapling instrument is disclosed. The buttress applier cartridge includes a first loading region configured to interface with an anvil of the end effector and a second loading region configured to interface with an elongate channel of the end effector. The first loading region includes a first absorbable layer and a loading assembly for securing the first absorbable layer to the anvil as the anvil approaches the first absorbable layer. The second loading region includes a staple cartridge removably coupled to the buttress applier cartridge. The staple cartridge includes a deck and a second absorbable layer positioned on the deck.
