A surgical stapling apparatus (stapler) is provided. The stapler includes a housing, elongated member, and a reload. A cartridge is configured to selectively couple to a first jaw member of the reload and includes one or more resilient members thereon. An anvil operably supported on a second jaw member of the reload is configured to compress one or more fasteners ejected from the cartridge. The anvil includes one or more locking members thereon. A knife is configured to translate through the cartridge and anvil when the first and second jaw members are in a closed configuration. Engagement between the knife and the resilient member(s) causes the resilient member(s) to move from an initial configuration that allows the knife to travel distally past the locking member(s) to a final configuration that allows the locking member(s) to engage the knife.
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 slot
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; anda 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. 2. The surgical stapling apparatus according to claim 1, wherein a flange of the resilient member engages the cartridge housing in the first position and the flange does not engage the cartridge housing in the second position of the resilient member. 3. The surgical stapling apparatus according to claim 2, wherein the resilient member is moved to the second position when the drive member is moved to the advanced position. 4. The surgical stapling apparatus according to claim 1, further comprising one or more motors. 5. The surgical stapling apparatus according to claim 1, further comprising a manually operated trigger. 6. The surgical stapling apparatus according to claim 1, wherein the drive member has a knife. 7. The surgical stapling apparatus according to claim 1, further comprising a sled positioned in the cartridge assembly, the drive member being positioned to advance the sled as the drive member is moved to the advanced position. 8. The surgical stapling apparatus according to claim 1, wherein the resilient member is U shaped and has two tips. 9. The surgical stapling apparatus according to claim 1, wherein the locking member has a first end coupled to the anvil and a second opposite end with a cam surface. 10. The surgical stapling apparatus according to claim 9, wherein the second end engages the drive member to prevent the drive member from moving to the advanced position. 11. The surgical stapling apparatus according to claim 1, wherein the resilient member pivots the locking member upwardly to allow the drive member to pass when the cartridge assembly is coupled to the first jaw member. 12. 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 tissue contacting surface defining a first recess and a plurality of slots, the cartridge assembly including a fastener disposed in each of the plurality of slots;a resilient member having a tip disposed in the first recess, the resilient member being moveable from a first position in which the tip of the resilient member extends through the tissue contacting surface to a second position in which the tip is disposed at or below the tissue contacting surface;a second jaw member having an anvil with staple forming depressions, the anvil defining a second recess in vertical registration with the first recess;a drive member supported for movement from a retracted position to an advanced position, the drive member being positioned to drive the fasteners toward the anvil; anda locking member operably coupled to a side wall of the anvil, the locking member being moveable between a first position in which the locking member is positioned to prevent advancement of the drive member and a second position in which the locking member is positioned to allow movement of the drive member, the locking member having an end aligned with the resilient member when the cartridge assembly is coupled to the first jaw member, the tip of the resilient member engaging the end of the locking member to move the locking member to the second position.
