An anvil assembly comprising:
- a center rod assembly;
- and
- a head assembly pivotally supported on the center rod assembly between an operative position and a tilted position, the head assembly including:
- a housing;
- a post extending proximally from the housing and defining a proximal annular groove;
- and
- a backup member operably supported about the post, wherein the backup member is movable from a first position in which a portion of the backup member is positioned to prevent pivotal movement of the head assembly from the operative position to the tilted position, to a second position in which the backup member is positioned to permit pivotal movement of the head assembly from the operative position to a tilted position, the backup member including a first locking feature and a second locking feature receivable within the proximal annular groove of the post to maintain the backup member in the first position.
