Abstract
A surgical stapler includes an anvil half and a cartridge half. The anvil half includes an anvil channel member and an anvil surface. The cartridge half releasably couples with the anvil half and includes a cartridge channel member having a distal portion that receives a staple cartridge, and a latching member coupled to the cartridge channel member and movable between open and closed positions. A resilient member is arranged at a proximal end of one of the anvil half or the cartridge half, and a projection is arranged at a proximal end of the other of the anvil half or the cartridge half. The resilient member is configured to contact and releasably couple with the projection to thereby couple the proximal end of the anvil half with the proximal end of the cartridge half while the latching member is in the open position.
