Abstract

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.

Claims (18)

1. A device for the transmission of ultrasonic vibrations that establishes a plurality of node and anti-node positions along a central axis of an ultrasonic waveguide, said device comprising: said ultrasonic waveguide comprising: a waveguide tube, a waveguide fitting, and an impact surface; said waveguide tube having a proximal end and a distal end; said waveguide fitting having an attachment end and a waveguide tube coupler; said waveguide tube coupler adapted to receive and fixedly secure to said proximal end of said waveguide tube; a spring and a shock-pulsing mass, each positioned on said ultrasonic waveguide; a stop positioned on said ultrasonic waveguide; said spring and said shock-pulsing mass are both interposed between said stop and said impact surface; a second shock-pulsing mass; said second shock-pulsing mass abuts against said stop; said shock-pulsing mass abuts against said impact surface; and said spring positioned between said shock-pulsing mass and said second shock-pulsing mass; and said impact surface positioned within at least one λ/6 of an anti-node position along the central axis of said ultrasonic waveguide when said attachment end of said waveguide fitting is attached to an operating device.

2. The device of claim 1 wherein said stop is positioned within at least one λ/6 of an anti-node position along the central axis of said ultrasonic waveguide.

3. The device of claim 1 wherein said stop is positioned within at least one λ/3 of an anti-node position along the central axis of said ultrasonic waveguide.
