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.

A surgical stapling apparatus, comprising: a first jaw member defining a channel;a lockout assembly supported on the first jaw member and including a locking lever rotatably mounted and biased by a resilient member toward the channel;a cartridge configured to selectively couple to the first jaw m
1. A surgical stapling apparatus, comprising: a first jaw member defining a channel;a lockout assembly supported on the first jaw member and including a locking lever rotatably mounted and biased by a resilient member toward the channel;a cartridge configured to selectively couple to the first jaw member, the cartridge having fasteners and a drive assembly that retains the locking lever away from the channel, the drive assembly including a sled that interacts with a pusher to drive fasteners out of the cartridge;a drive member movable through the channel from a retracted to an advanced position;a second jaw member having an anvil with staple forming depressions;the drive member driving the fasteners toward the anvil when moved to the advanced position, movement of the pusher releasing the locking lever; andan actuator in the cartridge, the actuator being coupled to the sled and biased against the pusher;wherein the actuator is positioned between wedge members of the sled. 2. A surgical stapling apparatus, comprising: a first jaw member defining a channel;a lockout assembly supported on the first jaw member and including a locking lever rotatably mounted and biased by a resilient member toward the channel;a cartridge configured to selectively couple to the first jaw member, the cartridge having fasteners and a drive assembly that retains the locking lever away from the channel, the drive assembly including a sled that interacts with a pusher to drive fasteners out of the cartridge; anda drive member movable through the channel from a retracted to an advanced position; anda second jaw member having an anvil with staple forming depressions;the drive member driving the fasteners toward the anvil when moved to the advanced position, movement of the pusher releasing the locking lever. 3. The surgical stapling apparatus according to claim 2, wherein the drive member pushes the sled when moved to the advanced position, the sled driving the pusher. 4. The surgical stapling apparatus according to claim 2, further comprising an actuator in the cartridge, the actuator being coupled to the sled and biased against the pusher. 5. The surgical stapling apparatus according to claim 4, wherein the actuator rotates the locking lever away from the channel when the cartridge is coupled to the first jaw member. 6. The surgical stapling apparatus according to claim 5, wherein the actuator has a proximally extending finger aligning with the lockout assembly when the cartridge couples to the first jaw member. 7. The surgical stapling apparatus according to claim 5, wherein the locking lever has a boss disposed for contact with the finger. 8. The surgical stapling apparatus according to claim 2, wherein the locking lever has an angled leading edge. 9. The surgical stapling apparatus according to claim 8, wherein the locking lever has a transverse edge that extends across the channel when the locking lever in in a position blocking the channel. 10. A surgical stapling apparatus, comprising: a first jaw member having a lockout assembly including a rotatably mounted locking lever;a drive member movable from a retracted to an advanced position and having a notch for engagement by the locking lever, the locking lever being biased toward the drive member for engagement with the notch;a cartridge configured to selectively couple to the first jaw member, the cartridge having fasteners and a sled for driving the fasteners from the cartridge when the drive member is moved to the advanced position, the cartridge having a rotatable actuator at a proximal end thereof for engagement with the locking lever when the cartridge is coupled to the first jaw member, the sled engaging the rotatable actuator to allow the drive member to move during firing; anda second jaw member having an anvil with staple forming depressions. 11. The surgical stapling apparatus according to claim 10, wherein the rotatable actuator has a protuberance and the sled has a cam feature for engaging the protuberance. 12. The surgical stapling apparatus according to claim 11, wherein the drive member is retractable to the retracted position and does not retract the sled, the locking lever engaging the notch in the drive member when the drive member is moved to the retracted position. 13. The surgical stapling apparatus according to claim 11, wherein the locking lever has a tab for interacting with a post portion on the rotatable actuator, so that the rotatable actuator moves the locking lever away from the drive member when the protuberance of the rotatable actuator is contacted by the cam feature of the sled. 14. The surgical stapling apparatus according to claim 10, wherein the sled engages the actuator when moved by the drive member. 15. The surgical stapling apparatus according to claim 14, wherein the actuator has a post portion that contacts and rotates the locking lever from a position in engagement with the notch into an unlocked position when the sled is moved. 16. The surgical stapling apparatus according to claim 15, wherein the actuator is disposed above the locking lever and extends distally therefrom. 17. The surgical stapling apparatus according to claim 16, wherein the post portion extends downwardly toward the locking lever. 18. The surgical stapling apparatus according to claim 10, wherein the locking lever is rotatably attached to the first jaw member by a boss and is biased toward the drive member by a spring. 19. The surgical stapling apparatus according to claim 10, wherein the locking lever has a concave portion for allowing passage of the drive beam.
