Abstract
An ultrasonic trocar system includes a cannula having a guide bore, an obturator to be passed through the guide bore of the cannula so that the obturator can be removed, and a vibration generator for generating ultrasonic vibrations to be propagated to the obturator. The obturator is vibrated at an ultrasonic frequency to puncture a somatic layer. An intermediate member is interposed between the cannula and obturator.
