Abstract: A surgical instrument, has an end effector that includes an ultrasonic blade, and a clamp arm that moves relative to the ultrasonic blade from an opened position toward an intermediate position and a closed position. The clamp arm is offset from the ultrasonic blade to define a predetermined gap in the intermediate position between the opened position and the closed position. A clamp arm actuator connects to the clamp arm and moves from an opened configuration to a closed configuration to direct the clamp arm from the opened position toward the intermediate position and the closed position. A spacer connects with the clamp arm to inhibit movement of the clamp arm from the intermediate position toward the closed position for maintaining the predetermined gap between the clamp arm and the ultrasonic blade.

Abstract: A surgical instrument includes an end effector, a shaft assembly, and a torque wrench integrally connected with the shaft assembly. The shaft assembly has an acoustic waveguide extending therethrough and the end effector projects distally from the shaft assembly. The acoustic waveguide has a proximal end portion configured to rotatably couple with an ultrasonic transducer assembly. The torque wrench is configured to transmit torque applied to the acoustic waveguide up to a predetermined torque. A portion of the torque wrench is configured to deflect upon receipt of torque greater than the predetermined torque. Accordingly, the portion of the torque wrench slips relative to the acoustic waveguide for limiting coupling of the acoustic waveguide to the ultrasonic transducer assembly to the predetermined torque.

Abstract: An apparatus comprises a body assembly, a shaft, an acoustic waveguide, an articulation section, an end effector, and an articulation drive assembly. The shaft extends distally from the body assembly and defines a longitudinal axis. The acoustic waveguide comprises a flexible portion. The articulation section is coupled with the shaft. A portion of the articulation section encompasses the flexible portion of the waveguide. The articulation section comprises a plurality of body portions aligned along the longitudinal axis and a flexible locking member. The flexible locking member is operable to secure the body portions in relation to each other and in relation to the shaft. The end effector comprises an ultrasonic blade in acoustic communication with the waveguide. The articulation drive assembly is operable to drive articulation of the articulation section to thereby deflect the end effector from the longitudinal axis.
