ABSTRACT:
An instrument for providing high pressure fluid pulses for cutting tissue including an internal pressure intensifying mechanism, and the provision of a suction force at the distal end of the instrument including an internal vacuum generating device to increase the suction force provided by a conventional suction source. A piston mechanism is provided for converting a low pressure fluid input to a high pressure fluid output, and a second piston mechanism is provided to intensify the suction force created by a conventional suction source at the surgical site.
