- 12. A surgical fastener applying apparatus comprising a reusable anvil half-section, a reusable cartridge receiving half-section, and a disposable firing assembly configured to be releasably supported within the cartridge receiving half section, the firing assembly including a disposable pusher assembly and a single use loading unit operably mountable to the pusher assembly, wherein the single use loading unit is not operably mountable to the pusher assembly if the pusher assembly is mounted in the cartridge receiving half section.
- 16. A disposable firing assembly for use with a surgical fastener applying apparatus comprising a disposable single use loading unit and a disposable pusher assembly, the pusher assembly insertable into a cartridge receiving half section of the fastener applying apparatus, the single use loading unit operably mountable to the pusher assembly, wherein the pusher assembly includes a lockout member movable from a first position preventing operable insertion of the single use loading unit therein and a second position enabling operable insertion of the single use loading unit therein.
