Abstract
An ultrasonic surgical instrument includes an end effector having an ultrasonic blade, an ultrasonic transducer assembly, and a shaft assembly the shaft assembly includes a tube, an acoustic waveguide, and a sheath radially positioned between the acoustic waveguide and the tube. The acoustic waveguide is received within the tube and is acoustically connected between the ultrasonic blade and ultrasonic transducer assembly to communicate ultrasonic vibrations from the ultrasonic transducer assembly to the ultrasonic blade. The acoustic waveguide extends along a longitudinal axis. The sheath includes a sheath body having an outer body surface and a plurality of damping rings radially extending from the outer body surface and engaged with the tube. The plurality of damping rings are configured to acoustically isolate the acoustic waveguide from the tube.
