Abstract
A fluid jet surgical cutting instrument having a pressure generating mechanism disposed within the housing of the instrument. The pressure generating mechanism includes a piston member which is reciprocatingly movable within the housing by alternately supplying gas to the distal end of the piston and the proximal end of the piston. The gas is supplied in an alternating manner through the provision of a novel actuator mechanism which includes a plurality of passageways which permits charging of gas to the pressure amplifying mechanism as well as venting of gas from the pressure amplifying mechanism to permit reciprocating movement.
