    摘要： An ultrasonic generator for a transducer is provided. The ultrasonic generator includes a function generator and a controller. The function generator is in signal communication with the transducer. The controller is in signal communication with the function generator and cooperates with the function generator to facilitate generation of a drive signal from the function generator to the transducer. An amplifier module is in signal communication with the function generator to amplify the drive signal.

    摘要： A single probe percutaneous surgical instrument for de-bulking/removing thrombus/clog/calculi has an actuator assembly (4), a probe set (13), an operating switch (10), and a generator (12). The actuator assembly (4) has a proximal end (4a) and a distal end (4b), a cable connector (1), a suction connector (2), and actuator switch (3) mounted with the proximal end (4a) and a horn (5) mounted at the distal end (4b). The probe set (13) is mounted to the horn (5) and includes at least one disturber (6), a spring (7), a 10 spring adjusting nut (8) and a fixed probe (9), the cable connector (1) connecting to the generator (12) through a cable, and the suction connector (2) connecting to a suction system. The actuator switch (3) controls a probe vibration mode through the generator (12), the actuator assembly (4) comprising at least two piezoelectric ceramic rings (18) assembled with a bolt (15), the horn (5) and a back plated (16). The horn (5) is mounted on the distal end (4b) of the actuator assembly (4), the horn (5) being coupled with the bolt (15) and the piezoelectric rings (18), the at least one disturber (6) and the spring (7) being mounted on the fixed probe (9) using the spring adjusting nut (8). The generator (12) includes a microprocessor and the microprocessor is programmed to control the actuator vibration mode, the fixed probe optimal vibration frequency and the disturbing strength of the disturbers.

    摘要： A percutaneous surgical instrument for de-bulking calculi or drilling bone includes an actuator for generating vibrations at ultrasonic frequencies and a horn coupled to said actuator for amplifying the actuator vibration. A fixed probe is attached to said horn for engaging the calculi and introducing the ultrasonic frequencies thereto. A floating probe is disposed concentric to and over said fixed probe and slidable thereover. A free mass is disposed between the horn and the floating probe for oscillating therebetween, in response to actuator vibration, for causing low frequency impact with the calculi.

    摘要： The disc recording cutter head is carried on the inner end of an arm which is pivoted intermediate its ends. A counterbalance weight on the outer end of the arm exactly counterbalances the cutter head. A direct current torque motor mounted on the pivot axis applies cutting force to the cutting stylus. Additional features optionally include damping of arm motion by arm position feedback to the torque motor and control of the cutting force as a function of stereo program material.

    摘要： What is presented is an ultrasonic waveguide for the transmission of ultrasonic vibrations that establishes a plurality of node and anti-node positions that are each along the ultrasonic waveguide's central axis. The ultrasonic waveguide comprises a waveguide tube, which has both a proximal end and a distal end; a waveguide fitting, which has both a threaded end and a impact surface; and a spring, shock-pulsing mass, and stop. Both the spring and shock-pulsing mass are each positioned on the waveguide tube. Whereas, the stop is positioned on the waveguide tube and it is adapted to non-fixedly engage the spring and shock-pulsing mass. The impact surface of the waveguide fitting is located at an anti-node position, which is along the central axis of the ultra-sonic waveguide when its installed within ultrasonic transducer while in operation.
