ABSTRACT:
An ultrasonic surgical liposuction apparatus comprises a piezoelectric crystal transducer assembly is connectable to an interchangeable operative probe and a damping body attached to the probe. The probe can be hollow, if aspiration of the fatty tissue is desired, or it can be solid. The damping body is largely formed of a plastic material, to prevent the propagation of the ultrasonic waves from that portion of the probe where the damping body is mounted, to the surrounding biological tissues. Prevention of propagation of the ultrasonic energy from a portion of the probe prevents unwanted heating of that part of the surrounding tissues. The damping body can be removable or permanently affixed, such as by welding. The damping body can have a metal jacket covering a portion of the surface of the damping body, or the damping body can be entirely made of plastic. The damping body can also have an opening or a plurality of openings for aspiration of the fatty tissue.
