1. A surgical stapling apparatus, comprising:
a housing; an elongated member extending from the housing; a reload supported on a distal end of the elongated member, the reload including a first jaw member releasably supporting a cartridge and a second jaw member supporting an anvil, the cartridge supporting a slide deflector that is movable from a first position to a second position; at least one lockout step provided on one of the first and second jaw members; a drive member including a working end configured to translate from a retracted position to an extended position through the reload when the first and second jaw members are in a closed configuration, the working end being urged to move toward the at least one lockout step; and an actuation sled positioned distally of the drive member such that movement of the drive member from the retracted position to the extended position advances the actuation sled through the cartridge; wherein, in the first position, the slide deflector is positioned to prevent engagement of the working end of the drive member with the at least one lockout step, and in the second position the slide deflector is positioned to allow engagement of the working end of the slide deflector with the at least one lockout step to prevent further advancement of the working end; wherein distal translation of the working end causes the slide deflector to move from the first position to the second position. |
