Abstract: A surgical stapler is provided that includes a spring loaded lift that automatically adjusts a staple cartridge and/or staple formation between a range of sizes. The lift is automatically released as the staple firing mechanism begins its forward translation of the firing sequence. The automatic one-way adjustment also adjusts the staple cartridge while maintaining the cartridge parallel to the anvil to provide consistent staple formations.

Abstract: A cartridge for use with a surgical instrument includes a curved body and a deck configured to clamp tissue against an anvil. A plurality of staple openings is formed in the deck and is configured to house a plurality of staples. An arcuate slot formed in the deck is configured to slidably receive a cutting member therethrough. An opening formed in the deck adjacent to an end of the arcuate slot is configured to slidably receive a pin therethrough. The cartridge further includes a raised surface offset from the deck and extending circumferentially about at least a portion of the opening. The raised surface is configured to clamp tissue against the anvil to thereby fix the tissue relative to the opening.

Abstract: A retainer for assembling tissue thickness compensators to a surgical stapler can comprise a grip, a first surface for supporting a first tissue thickness compensator, a second surface for supporting a second tissue thickness compensator, and clips for aligning and attaching the retainer to the surgical stapler. The clips may align and attach the retainer to a staple cartridge of the surgical instrument. The clips may align the retainer with an anvil of the surgical instrument. An insertion tool may be used in combination with the retainer to insert the retainer into the surgical stapler and to push the tissue thickness compensators against the anvil and/or the staple cartridge of the surgical instrument.

Abstract: An anvil-attachable layer for use with a surgical stapler, or fastening instrument, wherein a proximal end portion of the layer is attached to a staple cartridge assembly, for example. The layer may be attached to the staple cartridge assembly by an adhesive, weld, or a staple-cartridge-based clamp, wherein the attachment is weak enough to allow the layer to pull away from the staple cartridge assembly with stapled tissue. Alternatively, the layer can include two or more lateral slits that define a connector region that can be cut by a knife of a surgical stapler to release the layer.
