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 configured to selectively couple to the first jaw member, the cartridge defining a channel and having fasteners and a platform area, the platform area defining an aperture;a second jaw member having an anvil with staple for
1. A surgical stapling apparatus, comprising: a first jaw member;a cartridge configured to selectively couple to the first jaw member, the cartridge defining a channel and having fasteners and a platform area, the platform area defining an aperture;a second jaw member having an anvil with staple forming depressions;a drive member movable from a retracted position to an advanced position, the drive member being configured to drive the fasteners toward the anvil;an actuator rotatably disposed in the aperture of the cartridge and having a head portion at a first end, and a notch at a second end, the actuator being biased by a resilient member from a first position to a second position, the head portion having a tip extending into the channel when the actuator is in the first position; andan interlock having an extension and being rotatably disposed adjacent the actuator so that the extension is engaged with the notch when the actuator is in the first position, the interlock moving to a position blocking the channel when the actuator moves to the second position. 2. The surgical stapling apparatus according to claim 1, wherein the drive member has a flange that contacts the head portion when the drive member moves from the retracted position to the advanced position. 3. The surgical stapling apparatus according to claim 2, wherein the actuator is biased in a first direction, towards the second end, so that the head portion moves in a second direction, towards the first end, when contacted by the flange. 4. The surgical stapling apparatus according to claim 3, wherein the actuator moves in the second direction to the second position so that the notch is moved away from the extension. 5. The surgical stapling apparatus according to claim 3, wherein a surface of the head portion has a protuberance for engaging the platform area to move the actuator in the second direction. 6. The surgical stapling apparatus according to claim 1, wherein the actuator has beveled side edges to facilitate rotation of the actuator. 7. The surgical stapling apparatus according to claim 1, wherein the head portion has a cone-like shape. 8. The surgical stapling apparatus according to claim 1, wherein the interlock engages a rivet in the position blocking the channel. 9. The surgical stapling apparatus according to claim 1, wherein the interlock is biased toward the position blocking the channel. 10. The surgical stapling apparatus according to claim 1, wherein the drive member includes a trailing surface, the trailing surface engaging the interlock when the drive member is moved from the advanced position to the retracted position. 11. The surgical stapling apparatus according to claim 1, further comprising one or more motors. 12. The surgical stapling apparatus according to claim 1, further comprising a manually operated trigger. 13. The surgical stapling apparatus according to claim 1, wherein the interlock prevents advancement of the drive member from the retracted position when the actuator is in the second position. 14. A surgical stapling apparatus, comprising: a first jaw member;a second jaw member;a cartridge configured to selectively couple to the first jaw member, the cartridge including a plurality of fasteners and defining a channel and an aperture;a knife translatable from a retracted position to an advanced position to drive the plurality of fasteners from the cartridge toward the second jaw member;an actuator rotatably supported on the cartridge, the actuator having a tip extending into the channel in a first position of the actuator and positioned outside of the channel in a second position of the actuator, the actuator being biased by a resilient member towards the second position; andan interlock having a nonblocking position and a blocking position, the interlock preventing translation of the knife from the retracted position towards the advanced position when the interlock is in the blocking position, wherein the interlock rotates to the blocking position in response to the actuator rotating to the second position. 15. The surgical stapling apparatus according to claim 14, wherein the resilient member is configured to engage the actuator to bias the actuator towards the second position.
