An apparatus includes a cartridge body, a deck, an elongate slot, a plurality of pockets, and a plurality of engagement protrusions. The plurality of pockets include first and second pockets. The plurality of engagement protrusions extend from the deck and are configured to grip tissue or an adjunct material. The plurality of engagement protrusions include first and second engagement protrusions. The first engagement protrusion is associated with the first pocket. The first engagement protrusion includes a lateral portion extending longitudinally along a lateral side of the first pocket. The first engagement protrusion does not extend along a second lateral side of the first pocket such that the second lateral side opens directly to the deck. The second engagement protrusion is associated with the second pocket. The second engagement protrusion includes a lateral portion extending longitudinally along the second lateral side of the second pocket.

Surgical stapler cartridge having intermediate raised tissue engagement protrusions

Staple cartridge for a linear surgical stapler

An apparatus includes a handle assembly having a body, a shaft assembly having an outer tube member, an end effector, an anvil, a first trocar closure system, and a second trocar closure system. The end effector has having a staple deck fixed relative to the body, a staple driver operable to actuate relative to the staple deck between an unfired position and a fired position, and the trocar configured to selectively couple with the anvil and actuate relative to the staple dreck. The first trocar closure assembly can actuate in a first motion to drive the trocar between a distal position and a first closed position. The second trocar closure assembly can actuate in a second motion between the first closed position and a second closed position. The staple drive is inoperable at least until the first trocar closure assembly actuates the trocar to the first closed position.

Dual stage closure system for circular surgical stapler

A surgical instrument includes a stapling assembly and an anvil configured to cooperate to compress, staple, and cut tissue. The stapling assembly includes a deck member having a deck surface that faces distally and includes a plurality of staple openings configured to receive a plurality of staples, and a knife member having a distal end that defines a cutting edge. The anvil includes an anvil surface having a plurality of staple forming pockets configured to form the staples, and a washer positioned adjacent to the anvil surface and having a proximal face. The cutting edge of the knife member is configured to cut through the tissue and the proximal face when the surgical instrument is fired. The proximal face includes a tissue gripping feature configured to stabilize and inhibit the tissue from translating across the washer and the anvil surface during firing.
