A method of adjusting a staple parameter of a surgical stapling instrument is disclosed. The method includes determining, by a control circuit of the surgical stapling instrument, a first stroke length for a first staple driver of the surgical stapling instrument to drive a first row of staples of a circular stapling head assembly of the surgical stapling instrument; detecting, by the control circuit, a malformed staple in the first row of staples; adjusting, by the control circuit, the staple parameter, based on the detection of the malformed staple; and determining, by the control circuit, a second stroke length for a second staple driver of the surgical stapling instrument to drive a second row of staples of the circular stapling head assembly.

An apparatus includes a first stapling assembly, a plurality of staples a plurality of staple drivers, and a second stapling assembly portion. The first stapling assembly portion has a deck surface defining a plurality of apertures. The staple drivers can drive the plurality of staples through the staple apertures of the deck surface. The second stapling assembly can couple with the first stapling assembly portion. The second stapling assembly portion has a section that overlies the deck surface. At least one of the first or second stapling assembly portions include a first support feature that inhibits deflection of the deck surface during stapling.

A surgical stapling assembly comprising a cartridge body, a plurality of staples, a plurality of staple drivers, a sled, and a support plane is disclosed. The cartridge body comprises a deck, a plurality of staple cavities defined in the deck, a longitudinal slot defined in the deck, and an outer cartridge wall. The support plane extends perpendicular to a longitudinal axis, wherein the sled is positioned under an inner cartridge wall in the support plane, wherein the inner cartridge wall comprises a first lateral pillar width and a first pillar height in the support plane, wherein the outer cartridge wall comprises a second lateral pillar width and a second pillar height in the support plane, and wherein the first lateral pillar width is wider than the second lateral pillar width.

An apparatus includes a shaft assembly and an end effector. The shaft assembly includes an outer sheath and a staple driving mechanism. The end effector includes a staple deck, an anvil, a first staple driver, and a second staple driver. The staple deck defines a plurality of staple openings in at least one annular array. Each staple opening in the plurality of staple openings houses a staple. The anvil is configured to actuate relative to the staple deck to compress tissue between the staple deck and the anvil. The staple driving mechanism is configured to actuate the first staple driver to fire a first staple of the plurality of staples against the anvil. The staple driving mechanism is further configured to actuate the second staple driver independently of the first staple driver to fire a second staple of the plurality of staples against the anvil.

A surgical device having at least one rotary input screw in the end effector is provided. A rotary input screw can extend through a central longitudinal portion of the end effector. The end effector can include an improved closure system, firing systems, leveraging and alignment features between the staple cartridge and the surgical device, staple cartridges having multi-staple drivers, single-firing knife and lockout / safety features for the same, and / or modified staple patterns, for example. Certain components can be 3D-printed components.

The utility model provides a nail bin assembly, an executing mechanism and a surgical anastomat, the nail bin assembly comprises an anastomosis nail, the anastomosis nail comprises a nail leg and a nail beam which are connected with each other, the nail beam is provided with a first wave crest structure, and the first wave crest structure protrudes towards one side of the nail leg; the nail driver comprises a nail supporting part and a nail beam configured to support the anastomosis nail, a second wave crest structure is arranged at the position corresponding to the first wave crest structure, and after the nail driver drives the anastomosis nail to be ejected, the anastomosis nail is bent on the forming structure and then is formed in a closed mode. The first wave crest structure and the second wave crest structure are used for reducing the distance between the highest point of the nail leg formed in a closed mode and the highest point of the nail beam. By designing the structure of the anastomosis nail and the structure of the nail driver, the nail beam is provided with the first wave crest structure protruding towards the nail leg, the nail driver is provided with the second wave crest structure supporting the first wave crest structure, the closed space limited by the nail leg and the nail beam after the anastomosis nail is closed and formed is reduced, and a better tissue anastomosis effect is provided.

An interchangeable staple cartridge for use with a surgical instrument is disclosed. The interchangeable staple cartridge comprises a cartridge body, staple cavities defined in the cartridge body, staples removably positioned in the staple cavities, and staple drivers configured to support the staples in the staple cavities. The staple drivers are movable between an unfired position and a fired position. The staple cartridge further comprises a wedge sled and a driver retention member, wherein the wedge sled is configured to urge the staple drivers from the unfired position to the fired position; the driver retention member extends into the staple cavities. The driver retention member is configured to retain the staple drivers in the unfired position.
