  • Staple retainer for surgical stapler cartridge
    Patent number: 11166721
    Abstract: A staple retainer for a surgical staple cartridge unit includes a body having first and second body sides configured to be positioned within an aperture defined between an anvil and a deck of the cartridge unit such that the first body side confronts the anvil and the second body side confronts the deck. The second body side is configured to retain staples within openings in the deck. A first protrusion at the first body side is configured to contact the anvil at a first location, and a second protrusion at the first body side is configured to contact the anvil at a second location. The protrusions are configured to resiliently deflect toward the second body side in response to the staple retainer being positioned within the aperture, and are further configured to cooperate with the second body side to maintain a predetermined distance between the anvil and the deck.
