  • Patent number: 8973805
    Abstract: A surgical fastener applying apparatus includes a cartridge-receiving assembly and a cartridge assembly releasably engagable therewith. The cartridge assembly includes a housing and a knife assembly having a knife translatable from an initial position to a deployed position and a knife guard pivotable between a storage position, wherein the knife guard substantially encloses the knife member, and a use position, wherein the knife member is exposed for translation through the housing. The knife guard engages to the knife member such that translation of the knife member rotates the guard to the use position.

  • Publication number: 20120323226
    Abstract: A hand-held electromechanical surgical device is provided and configured to selectively connect with a surgical accessory. The surgical device includes a device housing defining a connecting portion for selectively receiving a coupling assembly of the surgical accessory. The connecting portion includes an annular wall defining a cylindrical recess dimensioned to receive the coupling assembly of the surgical accessory; a collar slidably supported about the annular wall, wherein the collar is slidable between a first position and a second position; and at least one socket member interposed between the annular wall and the collar, wherein each socket member is slidably supported in the annular wall. Each socket member includes a first fixed state wherein each socket member projects into the cylindrical recess of the annular wall; and a second movable state wherein each socket member is free to not project into the cylindrical recess of the annular wall.
