Abstract
A surgical nozzle apparatus used for removing an undesired tissue with a jet of pressurized fluid. A handpiece including a fluid injecting nozzle piece and a valve assembly capable of cutting off the supply of the pressurized fluid to the nozzle piece, further includes a suction nozzle opening at a position downstream of the nozzle piece. The suction nozzle is connected to external suction means so that the waste fluid and the separated tissue at a surgically treated part are simultaneously sucked and discharged during the operation.
