A surgical instrument including a handle portion, a body portion, an articulating tool assembly and a locking assembly is disclosed. The handle portion includes a movable handle. The body portion extends distally from the handle portion and defines a first longitudinal axis. The articulating tool assembly defines a second longitudinal axis and is movable from a first position where the second longitudinal axis is substantially aligned with the first longitudinal axis to at least a second position where the second longitudinal axis is at an angle to the first longitudinal axis. The locking assembly includes a member that is advanceable distally with respect to the body portion. The member engages the articulating tool assembly upon manipulation of the movable handle to move an anvil and a cartridge assembly in approximation with one another to help maintain the articulating tool assembly in its first position. |
