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, and an waveguide. The 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 waveguide includes an acoustic body, a first isolation structure, a second isolation structure and a sheath. The acoustic body extends along a longitudinal axis. The first isolation structure radially extends about the acoustic body. The second isolation structure radially extends about the acoustic body and is longitudinally spaced from the first isolation structure. The sheath is radially positioned between the first isolation structure and the tube and is further radially positioned between the second isolation structure.
