A surgical stapling apparatus (stapler) is provided and is configured to couple to a reload. The reload includes a first jaw member releasably supporting a cartridge that includes a slide deflector that is movable from a first position to a second position. One or more lockout steps are provided on one of the first and second jaw members of the reload. A drive member includes a working end urged to move toward the lockout step. In the first position, the slide deflector is positioned to prevent engagement of the working end of the drive member with the lockout step, and in the second position the slide deflector is positioned to allow engagement of the working end with the lockout step to prevent further advancement of the working end. Distal translation of the working end causes the slide deflector to move from the first position to the second position.

1. A surgical stapling apparatus, comprising: a housing;an elongated member extending from the housing;a reload supported on a distal end of the elongated member, the reload including a first jaw member releasably supporting a cartridge and a second jaw member supporting an anvil, the cartridge supporting a slide deflector that is movable from a first position to a second position;at least one lockout step provided on one of the first and second jaw members;a drive member including a working end configured to translate from a retracted position to an extended position through the reload when the first and second jaw members are in a closed configuration, the working end being urged to move toward the at least one lockout step; andan actuation sled positioned distally of the drive member such that movement of the drive member from the retracted position to the extended position advances the actuation sled through the cartridge;wherein, in the first position, the slide deflector is positioned to prevent engagement of the working end of the drive member with the at least one lockout step, and in the second position the slide deflector is positioned to allow engagement of the working end of the slide deflector with the at least one lockout step to prevent further advancement of the working end;wherein distal translation of the working end causes the slide deflector to move from the first position to the second position. 2. The surgical stapling apparatus according to claim 1, wherein the drive member includes a beam including a distal end having a pre-bent configuration that biases the working end towards the at least one lockout step. 3. The surgical stapling apparatus according to claim 2, wherein the slide deflector is removably coupled to the actuation sled of the cartridge. 4. The surgical stapling apparatus according to claim 1, wherein at least one resilient member is configured to bias the working end towards the at least one lockout step. 5. The surgical stapling apparatus according to claim 4, wherein the at least one resilient member is coupled to a pivoting member of the surgical stapling apparatus. 6. The surgical stapling apparatus according to claim 5, wherein the at least one resilient member includes a generally arcuate contacting portion that allows the working end to slide therepast and into contact with one of the slide deflector and at least one lockout step. 7. The surgical stapling apparatus according to claim 1, wherein the at least one lockout step is provided on each of the anvil and first jaw member. 8. The surgical stapling apparatus according to claim 1, wherein the slide deflector includes at least one detent thereon that is configured to engage a corresponding indent on the working end and a corresponding indent disposed within the cartridge. 9. The surgical stapling apparatus according to claim 8, wherein the mechanical interfaces disposed on the slide deflector and within the cartridge form a dovetail joint. 10. The surgical stapling apparatus according to claim 1, wherein the slide deflector includes a mechanical interface that is configured to engage a corresponding mechanical interface disposed within the cartridge. 11. A surgical stapling apparatus, comprising: a housing;an elongated member extending from the housing;a reload supported on a distal end of the elongated member, the reload including a first jaw member releasably supporting a cartridge and a second jaw member supporting an anvil, the cartridge supporting a slide deflector that is movable from a first position to a second position;at least one lockout step provided on one of the first and second jaw members; anda drive member including a working end configured to translate from a retracted position to an extended position through the reload when the first and second jaw members are in a closed configuration, the working end being urged to move toward the at least one lockout step; andan actuation sled positioned distally of the drive member such that movement of the drive member from the retracted position to the extended position advances the actuation sled through the cartridge;at least one resilient member positioned for biasing the working end towards the at least one lockout step; andwherein, in the first position, the slide deflector is positioned to prevent engagement of the working end of the drive member with the at least one lockout step, and in the second position the slide deflector is positioned to allow engagement of the working end of the slide deflector with the at least one lockout step to prevent further advancement of the working end;wherein distal translation of the working end causes the slide deflector to move from the first position to the second position. 12. The surgical stapling apparatus according to claim 11, wherein the at least one lockout step is provided on each of the anvil and cartridge. 13. The surgical stapling apparatus according to claim 11, wherein the at least one resilient member is coupled to a pivoting member of the surgical stapling apparatus. 14. The surgical stapling apparatus according to claim 11, wherein the at least one resilient member includes a generally arcuate contacting portion that allows a knife to slide therepast and into contact with one of the slide deflector and at least one lockout step. 15. The surgical stapling apparatus according to claim 11, wherein the slide deflector is removably coupled to the actuation sled of the cartridge. 16. The surgical stapling apparatus according to claim 11, wherein the slide deflector includes at least one detent thereon that is configured to engage a corresponding indent on the working end and a corresponding indent disposed within the cartridge. 17. The surgical stapling apparatus according to claim 11, wherein the slide deflector includes a mechanical interface that is configured to engage a corresponding mechanical interface disposed within the cartridge. 18. Surgical stapling apparatus according to claim 17, wherein the mechanical interfaces disposed on the slide deflector and within the cartridge form a dovetail joint. 19. A reload configured to couple to a surgical stapling apparatus, comprising: a cartridge supported on a first jaw member of the reload, the cartridge supporting a slide deflector that is movable from a first position to a second position;at least one lockout step provided on one of the first and second jaw members;a drive member including a working end configured to translate from a retracted position to an extended position through the reload when the first and second jaw members are in a closed configuration, the working end being urged to move toward the at least one lockout step; andan actuation sled positioned distally of the drive member such that movement of the drive member from the retracted position to the extended position advances the actuation sled through the cartridge;wherein, in the first position, the slide deflector is positioned to prevent engagement of the working end of the drive member with the at least one lockout step, and in the second position the slide deflector is positioned to allow engagement of the working end of the slide deflector with the at least one lockout step to prevent further advancement of the working end;wherein distal translation of the working end causes the slide deflector to move from the first position to the second position.
