Abstract
A tranducer assembly for an ultrasonic surgical instrument includes a front driver having an elongate shaft in one direction and a stud extending in an opposite direction. An electromechanical transducer element is disposed around the stud. The transducer assembly also comprises a rear driver disposed around the stud on a side of the electromechanical transducer element opposite the front driver, the electromechanical transducer element being clamped between the front driver and the rear driver. An inertial or damping mass is fixedly connected to the stud at a point spaced from the rear driver. The stud is of length and thinness to act as a flexible vibration damping element.
