<P>PROBLEM TO BE SOLVED: To provide ultrasonic oscillator for suppressing thrombi having an effect for suppressing the growth of thrombi only by irradiating ultrasound without using medicine together and to provide a method for driving the same. <P>SOLUTION: The ultrasonic oscillator 10 for controlling thrombi is constituted such that an ultrasonic oscillator 11 is superposed on an acoustic lens 12, a reflecting plate 13 is arranged on the ultrasonic oscillator 11, and the whole body is covered with a liquid container 14 filled with refrigerant. The growth of thrombi can be suppressed only by the irradiation of ultrasound without using medicine dissolving thrombi by driving at a high-frequency vibration of a predetermined frequency for example at high-frequency vibration of a high-frequency of 500 kHz in the ultrasonic oscillator 10 for controlling thrombi. <P>COPYRIGHT: (C)2013,JPO&INPIT |
