Surgical apparatus for removing animal tissue - has pump providing pressurised pulsating stream of liquid

摘要

Apparatus suitable for disintegrating and removing animal tissue from a preselected enclosed area comprises a hand-manipulatable first tube having a distally disposed outlet port, a liquid pulsating pump having an inlet and an outlet, a source of liquid connected to the pump inlet, means including a flexible conduit connecting the first tube to the pump outlet a suction conduit including an outlet port disposed nearr to the first tube outlet port, a source of suction and means including a flexible conduit connecting the suction conduit to the source of suction. The pump is adapted to provide a stream of pulsating liquid through the first tube outlet port at a frequency between 1/4 to 333 pulses per second, at a pressure above atmospheric pressure of about 15 to about 3,500 p.s.i. and at a velocity of between 50 and 500 feet per second.
