摘要： An ultrasonic transducer for surgical applications is disclosed. The ultrasonic transducer comprises: a back mass; a front mass; an ultrasonic actuator arrangement held between the back mass and the front mass; and an ultrasonic horn arrangement forward of the front mass. The back mass, ultrasonic actuator arrangement, front mass and ultrasonic horn arrangement are arranged along a longitudinal axis of the transducer. Vibrations generated by the ultrasonic actuator arrangement are conducted into the front mass and into the ultrasonic horn arrangement along a vibrational energy transfer path and are amplitude amplified by the ultrasonic horn arrangement. One or more of the back mass, front mass and ultrasonic horn arrangement includes a plurality of openings opening towards the longitudinal axis and intersecting the vibrational energy transfer path and configured to provide an increased mechanical compliance in a direction along the vibrational energy transfer path.
