A first ultrasonic medical instrument includes an ultrasound transducer, a medical ultrasonic blade, and a tube adapted to contain a liquid. A first tube end is adapted to have the liquid proximate the first tube end, when the tube contains the liquid, be ultrasonically vibrated to generate an ultrasonically-vibrating energy wave. The ultrasonic blade is acoustically connected to the liquid proximate a second tube end, when the tube contains the liquid. A second ultrasonic medical instrument includes a heat pulse initiator, a medical ultrasonic blade, and a tube adapted to contain a liquid. The heat pulse initiator is adapted to output heat pulses having an ultrasonic pulse frequency. A first tube end is adapted to receive the heat pulses outputted by the heat pulse initiator, wherein the heat pulses have an energy sufficient to create an ultrasonically-vibrating energy wave in the liquid, when the tube contains the liquid. |
