1. A stapling system, comprising:
(a) a staple cartridge, comprising:
(i) a cartridge body comprising a proximal end, a distal end, and a one-way latch rotatable between an unlocked position and a locked position;
(ii) staples removably stored in the cartridge body; and
(iii) a sled movable distally from an unfired position to a fired position to eject the staples from the cartridge body during a staple firing stroke, wherein the sled comprises a cam configured to rotate the one-way latch from the unlocked position to the locked position during the staple firing stroke; and

(b) a stapling instrument, comprising:
(i) a first jaw configured to receive the staple cartridge;
(ii) a second jaw;
(iii) a firing system comprising a firing member movable distally to push the sled distally during the staple firing stroke; and
(iv) a firing member lockout configured to block the firing member from being moved distally through the staple firing stroke,

wherein the firing member lockout is configured to be deactivated by the sled when the staple cartridge is seated in the first jaw and the sled is in the unfired position,
wherein the sled is configured to be releasably attached to the firing member,
wherein the sled is retractable proximally by the firing member from the fired position to a retracted, spent position,
wherein the one-way latch in the locked position is configured to contact the sled in the retracted, spent position and thereby detach the sled from the firing member and prevent the sled from being retracted proximally from the retracted, spent position to the unfired position, and
wherein the firing member lockout is configured to prevent the firing member from being advanced distally through the staple cartridge when the sled is detached from the firing member and in the retracted, spent position.
