  • Submerged jet injection nozzle
    Patent number: 4798339
    Abstract: A submerged jet injection nozzle includes a nozzle exit disposed downstream of an orifice section and greater in diameter than the orifice section. The occurrence of cavitation due to a fluid injection is positively promoted so that the crushing effect of the cavitation is utilized fully and the decay in the energy of the injected fluid is reduced thereby increasing the work done by the submerged fluid injection.

  • Surgical nozzle apparatus
    Patent number: 4560373
    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.
