A circular fastener apparatus comprising:
- an elongated body;
- a fastener cartridge supported on the elongated body;
- an anvil retainer extending through the fastener cartridge;
- and
- a release mechanism including at least one lock, the at least one lock being movable between a first position in which the at least one lock is engaged with the anvil retainer to secure the anvil retainer within the fastener cartridge and a second position in which the at least one lock is disengaged with the anvil retainer to release the anvil retainer from within the fastener cartridge.
A circular fastener apparatus comprising:
- an elongated body having a proximal portion and a distal portion;
- a fastener cartridge supported on the distal portion of the elongated body;
- an anvil retainer extending through fastener cartridge, the anvil retainer defining at least one lock recess;
- and
- an anvil retainer release mechanism including a release housing, a release supported by the release housing and configured to move between a first position and a second position, and at least one lock operably coupled to the release, the at least one lock mounted for movement within the retainer housing between a locked position and an unlocked position upon movement of the release between the first and second positions, the at least one lock configured to be received within the at least one lock recess of the anvil retainer to secure the anvil retainer within the fastener cartridge when the at least one lock is in the locked position and configured to be released from the at least one lock recess to release the anvil retainer from within the fastener cartridge when the at least one lock is in the unlocked position.
