摘要:
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.

Surgical stapling instruments are disclosed. At least one embodiment includes a first jaw that supports a plurality of surgical staples and a second jaw that is movable relative to the first jaw. Various arrangements include a tissue thickness compensator that is configured to be captured within the surgical staples and assume different compressed heights within different surgical staples upon application of a firing motion to the surgical staples. Various attachment protrusion arrangements are disclosed to mechanically removably attach the tissue thickness compensator to the first or second jaw.

In various embodiments, a surgical stapling instrument can include a handle, a shaft extending from the handle, wherein the shaft defines an axis, and a disposable loading unit which is assembled to the shaft in a direction which is transverse to the shaft axis. Such a connection between the disposable loading unit and the shaft can prevent, or at least inhibit, the disposable loading unit from being unintentionally displaced proximally and/or distally relative to the shaft of the surgical instrument. The surgical stapling instrument and/or disposable loading unit can further include a threaded collar and/or detent assembly configured to hold the disposable loading unit in place. In various embodiments, a disposable loading unit can include a lockout feature which can prevent, or at least inhibit, an expended disposable loading unit from being reassembled to the elongated body of the surgical instrument.

In various embodiments, an anvil of a disposable loading unit including a first member having staple pockets for deforming staples, a first cover plate secured to the first member, and a second cover plate secured to at least one of the first member and the first cover plate, wherein the first and second cover plates can be configured to support the first member. In at least one embodiment, an anvil can include a first member inserted into a second member, where at least one of the first and second members can be deformed to retain one to the other. In various embodiments, a surgical stapling instrument can include a disposable loading unit comprising a staple cartridge, an anvil, and a sleeve, wherein the sleeve can be configured to be slid relative to the staple cartridge and the anvil to hold the anvil in a closed position.
