1. A surgical fastener applying apparatus comprising:
- an anvil half-section including a distal anvil portion and a proximal handle portion;
a cartridge receiving half-section defining an elongated channel member;
a stationary housing configured to be releasably supported within the elongated channel member of the cartridge receiving half-section, the stationary housing having a proximal portion supporting firing components of the apparatus, a distal portion dimensioned to releasably receive a single use loading unit, and a central portion including a lockout structure, the lockout structure being movable from a first position that prevents full insertion of the single use loading unit into the stationary housing and a second position that allows insertion of the loading unit into the stationary housing, wherein the lockout structure is retained in the first position when the stationary housing is received in the elongated channel member.
