Process of manufacturing an ultrasonic medical device

A method of fabricating an ultrasonic medical device comprising:

• machining a surgical tool from a portion of a flat metal stock, wherein the surgical tool comprises a longitudinal portion;
• contacting a face of a first transducer, via a first transducer portion fabricated in a form of a triangular prism, with a first face of the surgical tool, wherein the first transducer is configured to operate in a D31 mode with respect to the longitudinal portion of the surgical tool;
• contacting a face of a second transducer, via a second transducer portion fabricated in a form of a triangular prism, with an opposing face of the surgical tool and opposite the first transducer, wherein the second transducer is configured to operate in a D31 mode with respect to the longitudinal portion of the surgical tool;
• and
• subjecting the surgical tool to one or more metalworking processes;
• wherein, upon activation, the first transducer and the second transducer are configured to induce a standing wave in the surgical tool;
• and
• wherein the induced standing wave comprises a node at a node location in the surgical tool and an antinode at an antinode location in the surgical tool.
