摘要：
Disclosed is an ultrasonic medical device that may include a surgical tool having a proximal end, an end effector, and a waveguide between them, a first transducer in mechanical communication with a first face of the surgical tool, and a second transducer in mechanical communication with an opposing face of the surgical tool, opposite the first transducer. The first transducer and the second transducer are configured to operate in a D31 mode with respect to the waveguide of the surgical tool. Another aspect comprises a method of fabricating the ultrasonic medical device, in which the surgical tool is machined from a portion of a flat metal stock so that the surgical tool has a longitudinal axis oriented at an angle with respect to a grain direction of the flat metal stock thereby optimizing an operational characteristic of the surgical tool.
