Abstract
A surgical stapling device includes a tool assembly and a drive assembly for actuating the tool assembly. The tool assembly includes an anvil assembly that defines a notch and a cartridge assembly that includes a staple cartridge having a cartridge body that supports staples and pushers and an actuation sled that supports a knife. The drive assembly supports a lockout mechanism that is movable between unlocked position and locked positions. The knife includes a protrusion that engages the lockout mechanism to move the lockout mechanism to the unlocked position as the drive assembly is moved from a retracted position towards an advanced position. When a knife is not present within the staple cartridge, the lockout mechanism remains in the unlocked position to prevent advancement of the drive assembly.
