The anvil assembly (140) is translatable relative to the cartridge assembly (102) between a spaced position, where the anvil assembly (140) is spaced from the cartridge assembly (102), and an approximated position, where the anvil assembly (140) is in close cooperative alignment with the cartridge assembly (102) for clamping tissue disposed therebetween. A lockout sleeve (200) is slidably supported on the cartridge assembly (102) and translatable relative to the cartridge assembly (102) and the anvil assembly (140) between a first position and a second position. The lockout sleeve (200) is configured to engage the anvil assembly (140) and the cartridge assembly (102) when the lockout sleeve (200) is in the second position to inhibit translation of the anvil assembly (140) relative to the cartridge assembly (102) from the spaced position to the approximated position.
