摘要： An ultrasonic instrument includes a body, an actuation assembly, a shaft assembly, and an end effector. The actuation assembly includes a mode selection member and an activation member. The shaft assembly extends distally from the body. The shaft assembly includes an acoustic waveguide. The end effector includes an ultrasonic blade. The ultrasonic blade is in acoustic communication with the acoustic waveguide. The end effector is configured to be activated in a first activation mode in response to actuation of the activation member when the mode selection member is in a first position. The end effector is configured to be activated in a second activation mode in response to actuation of the activation member when the mode selection member is in a second position.

摘要： A surgical instrument includes a body, an ultrasonic blade, a clamp arm assembly, and a detent assembly. The clamp arm assembly includes a clamp arm pivotably coupled with the body at a pivot assembly. The clamp arm is operable to compress tissue against the ultrasonic blade. The detent assembly is configured to provide tactile resistance to pivotal movement of the clamp arm relative to the body beyond a predefined pivot angle. The detent assembly is configured to permit pivotal movement of the clamp arm relative to the body beyond a predefined pivot angle upon application of a force sufficient to overcome the tactile resistance

摘要： A surgical instrument includes a body, an ultrasonic blade, a clamp arm, and a resilient member. The body includes an electrical conductor and defines a longitudinal axis. The clamp arm is pivotably coupled with the body at a pivot assembly. The clamp arm is operable to compress tissue against the ultrasonic blade. The clamp arm includes an electrode operable to apply RF energy to tissue, wherein the clamp arm is configured to be loaded onto and removed from the body at the pivot assembly along a path that is transverse to the longitudinal axis defined by the body. The resilient member is located within the pivot assembly. The resilient member is configured to provide electrical continuity between the electrode of the clamp arm and the electrical conductor of the body.

摘要： 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.

摘要： A surgical apparatus comprises a body, an ultrasonic transducer, a shaft, an acoustic waveguide, an articulation section, an end effector, and an articulation drive assembly. 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 includes a collar that is located distal to a nodal portion of the waveguide and is operable to deflect the end effector away from the longitudinal axis. The end effector comprises an ultrasonic blade in acoustic communication with the ultrasonic transducer. The articulation drive assembly is operable to drive articulation of the articulation section. The articulation drive assembly comprises at least one translating articulation driver coupled with the collar. The ultrasonic blade is operable to deliver ultrasonic vibrations to tissue even when the articulation section is in an articulated state.
