Abstract
A surgical stapling device includes an adaptor assembly and a reload assembly supported on a distal end portion of the adaptor assembly. The reload assembly includes a shell housing, a staple cartridge supporting staples, a staple pusher, a staple actuator, a knife carrier, and a locking member. The staple pusher is movable from a retracted position to an advanced position to eject the staples from the staple cartridge. The staple actuator is movable from a retracted position to an advanced position to move the staple pusher from its retracted position to its advanced position. The knife carrier is movable between a retracted position and an advanced position. The locking member is supported on the knife carrier. The locking member is configured to engage the staple actuator in its advanced position while engaging the knife carrier in its retracted position such that the locking member inhibits re-advancement of the knife carrier.
