  • SURGICAL STAPLING APPARATUS
    Publication number: 20140263550
    Abstract: A surgical stapling apparatus (stapler) is provided. A tool assembly includes first and second jaw members. A cartridge assembly includes an actuation sled and a slide. A drive member having a working end is configured to translate through the tool assembly when the first and second jaw members are in a closed configuration. A lock assembly including a latch is movable from a locked position to an unlocked position. The latch is urged to the locked position to engage the working end to prevent distal translation of the drive member through the tool assembly. The slide is configured to move the latch from the locked position to the unlocked position upon installation of an unspent cartridge assembly onto the first jaw member. The slide is movable by the drive member upon actuation of the stapling apparatus to allow the latch to move back to the locked position.

  • SURGICAL STAPLING APPARATUS
    Publication number: 20140263546
    Abstract: A surgical stapling apparatus (stapler) is provided and is configured to couple to a reload. The reload includes a first jaw member releasably supporting a cartridge that includes a slide deflector that is movable from a first position to a second position. One or more lockout steps are provided on one of the first and second jaw members of the reload. A drive member includes a working end urged to move toward the lockout step. In the first position, the slide deflector is positioned to prevent engagement of the working end of the drive member with the lockout step, and in the second position the slide deflector is positioned to allow engagement of the working end with the lockout step to prevent further advancement of the working end. Distal translation of the working end causes the slide deflector to move from the first position to the second position.
