ABSTRACT

An investigation was made of the dynamics of ultrasonic vibrodrills with a common source of rotational and ultrasonic reciprocal motions. The source was constructed on the basis of an electroacoustic transducer of longitudinal vibrations. The dependences of power, rotation speed, and flutter rates were plotted for various pushers as a function of biological tissue drag torque. The results obtained allowed us to determine the optimal parameters of basic ultrasonic modes used in treating biological tissues. Apart from that, ultrasonic vibrodrill pilot models, which are new in principle, are presented. They were designed to be applied in traumatology. A distinguishing feature of these vibrodrills is that an electroacoustic transducer of longitudinal vibrations is a source of two motion types: rotational and ultrasonic reciprocal.
