Abstract: A surgical stapler includes a first stapler half including an anvil surface having a plurality of staple forming pockets, and a second stapler half configured to releasably couple with the first stapler half. The second stapler half is operable to deploy staples toward the anvil surface. The stapler also includes a projection positioned on one of the stapler halves and extending laterally relative to a longitudinal axis of the stapler. The stapler halves are configured to pivot relative to each other about the projection. The stapler further includes a locking member positioned on the other of the stapler halves. The locking member is configured to translate along the longitudinal axis of the stapler between a locked state in which the locking member selectively captures the projection and an unlocked state in which the locking member selectively releases the projection. The locking member is biased proximally toward the locked state.
