ABSTRACT:
A surgical stapling device including a self-righting anvil assembly is disclosed. The anvil assembly includes an anvil center rod and a pivotable anvil head. The surgical stapling device includes an anvil retainer assembly having a locking member in the form of a trocar for moving the anvil head from its tilted position to its operative position upon attachment of the anvil assembly to the stapling device. A cam member is provided to retain the locking member in a first or locked position and, thus, the anvil head in the operative position until after the stapling device has been fired.
