Abstract
A surgical stapler includes an anvil half having an anvil channel member and a cartridge half having a cartridge channel member. A latching lever is coupled to the cartridge channel member and is pivotable between a closed position in which the lever fixes the anvil channel member relative to the cartridge channel member, and an open position in which the lever permits relative movement between the channel members. A locking member coupled to a proximal portion of the cartridge half is movable between a locked position when the lever is in the closed position and an unlocked position when the lever is in the open position. In the locked position the locking member captures the projection and locks the anvil half proximal portion to the cartridge half proximal portion. In the unlocked position the locking member releases the projection and permits separation of the proximal portions.
