Zusammenfassung:A surgical instrument includes a body, a shaft assembly, an end effector, an actuation assembly, and a bailout mechanism. The shaft assembly extends distally from the body. The end effector is disposed on a distal end of the shaft assembly and includes a first jaw and a second jaw. The actuation assembly includes a pusher member configured to move relative to the end effector to drive movement of the first jaw, the second jaw, or both the first jaw and the second jaw. The bailout mechanism includes a first elongate actuation element and a second elongate actuation element. A portion of the bailout mechanism is configured to selectively apply tension to the first elongate actuation element and the second elongate actuation element to move the pusher member. The first elongate actuation element is stronger in tension than the second elongate actuation element cable.
