Claim:
1. A surgical stapling apparatus, comprising: a first jaw member; a cartridge assembly configured to be selectively coupled to the first jaw member, the cartridge assembly having a cartridge housing defining a first recess housing a resilient member, the cartridge housing defining a plurality of slots, a fastener disposed in each of the plurality of slots, the resilient member being moveable between a first position in which a tip of the resilient member extends above a surface of the cartridge housing and a second position in which the tip does not extend above the cartridge housing; a second jaw member having an anvil with staple forming depressions, the anvil having a locking member operably coupled to a sidewall of the anvil with a first position and a second position, an end of the locking member being aligned with the resilient member when the cartridge assembly is coupled to the first jaw member, the anvil defining a second recess in vertical registration with the first recess and configured to receive a portion of the resilient member; and a drive member movable from a retracted position to an advanced position for driving the fasteners toward the anvil, the locking member blocking movement of the drive member in the first position; the resilient member moving the locking member to the second position when the cartridge assembly is coupled to the first jaw member, the locking member allowing movement of the drive member when the locking member is in the second position.
