摘要：
A surgical instrument can comprise a handle, a shaft extending from the handle, and an end effector rotatably coupled to the shaft by an articulation joint. The surgical instrument can further include an articulation driver configured to rotate the end effector about the articulation joint and an articulation lock which can be configured to selectably resist the unintentional articulation of the end effector. In various circumstances, the actuation of the articulation driver can unlock the articulation lock. In certain circumstances, the articulation lock can comprise a first one-way lock configured to resist the movement of the articulation driver in a first direction and a second one-way lock configured to resist the movement of the articulation driver in a second direction.
