More Information
Summary:A surgical apparatus comprises a body, an ultrasonic transducer, a shaft, an acoustic waveguide, an articulation section, an end effector, and a rigidizing member. The ultrasonic transducer is operable to convert electrical power into ultrasonic vibrations. The shaft couples the end effector and the body together. The acoustic waveguide is coupled with the transducer. The articulation section is operable to flex to thereby deflect the end effector from a longitudinal axis defined by the shaft. The rigidizing member is operable to selectively rigidize the articulation section and thereby prevent deflection of the end effector by preventing flexibility of the articulation section. Such rigidization includes removing any "play" or other small movement that might otherwise be provided by the articulation section due to manufacturing tolerances and/or looseness between parts.
