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.
1. A surgical stapling apparatus, comprising: a housing;an elongated member extending from the housing;a tool assembly supported on a distal end of the elongated member, the tool assembly including a first jaw member and a second jaw member configured to move relative to each other between an open c
1. A surgical stapling apparatus, comprising: a housing;an elongated member extending from the housing;a tool assembly supported on a distal end of the elongated member, the tool assembly including a first jaw member and a second jaw member configured to move relative to each other between an open configuration and a closed configuration;a cartridge assembly including a plurality of staples, the cartridge assembly releasably supported on the first jaw member, the cartridge assembly including an actuation sled and a slide releasably coupled to the actuation sled;an anvil operably supported on the second jaw member;a drive member having a working end that is positioned and configured to translate through the first and second jaw members of the tool assembly when the first and second jaw members are in the closed configuration, the drive member being movable independently of the slide;a lock assembly including a latch movable from a locked position to an unlocked position, wherein in the locked position, the latch is positioned and configured to prevent distal translation of the drive member through the tool assembly; anda spring member positioned and configured to urge the latch towards the locked position wherein the slide is configured to move the latch from the locked position to the unlocked position upon installation of the cartridge assembly onto the first jaw member, the drive member moving the slide and the actuation sled distally upon actuation of the stapling apparatus, and in a distal configuration of the slide, the slide uncouples from the actuation sled and the spring member biases the latch to move to the locked position. 2. A surgical stapling apparatus according to claim 1, further including a pivot assembly, wherein the lock assembly is operably coupled to the pivot assembly. 3. A surgical stapling apparatus according to claim 2, wherein the lock assembly includes a cam pin configured to be contacted by the slide, the resilient member and at least one washer, and wherein the cam pin is positioned through an aperture defined through the pivot assembly, the cam pin being configured to rotate within the aperture to move the latch from the locked position to the unlocked position when the cam pin is contacted by the slide. 4. A surgical stapling apparatus according to claim 3, wherein the working end includes at least one recess that is configured to selectively engage the latch. 5. A surgical stapling apparatus according to claim 1, wherein the slide is configured to releasably couple to the actuation sled. 6. A surgical stapling apparatus according to claim 1, wherein the slide includes at least one mechanical interface that is configured to couple to a corresponding mechanical interface disposed within the cartridge assembly when the actuation sled is moved distally. 7. A surgical stapling apparatus according to claim 6, wherein the mechanical interfaces disposed on the slide and within the cartridge assembly form a dovetail joint. 8. A reload comprising: a tool assembly including a first jaw member and a second jaw member configured to move relative to each other between an open configuration and a closed configuration;a cartridge assembly releasably supported on the first jaw member, the cartridge assembly including an actuation sled and a slide releasably coupled to the actuation sled;an anvil supported on the second jaw member;a drive member having a working end configured to translate through the tool assembly when the first and second jaw members are in the closed configuration; anda lock assembly including a latch movable from a locked position to an unlocked position, wherein in the locked position, the latch is positioned and configured to prevent distal translation of the drive member through the reload,wherein the slide is configured to move the latch from the locked position to the unlocked position upon installation of the cartridge assembly onto the first jaw member, the slide being coupled to the actuation sled during installation of the cartridge assembly. 9. A reload according to claim 8, wherein the lock assembly is operably coupled to a pivot assembly of the reload. 10. A reload according to claim 9, wherein the lock assembly includes a cam pin configured to be contacted by the slide, at least one resilient member and at least one washer, and wherein the cam pin is positioned through an aperture defined through the pivot assembly, the cam pin being configured to rotate within the aperture to move the latch from the locked position to the unlocked position when the cam pin is contacted by the slide. 11. A reload according to claim 10, wherein the working end includes at least one recess that is configured to selectively engage the latch. 12. A reload according to claim 8, wherein the slide is configured to releasably couple to the actuation sled. 13. A reload according to claim 8, wherein the slide includes at least one mechanical interface that is configured to couple to a corresponding mechanical interface disposed within the cartridge assembly when the actuation sled is moved distally. 14. A reload according to claim 13, wherein the mechanical interfaces disposed on the slide and within the cartridge assembly form a dovetail joint.
