Ultrasound power device and ultrasound tumour therapeutic system

Abstract

The invention discloses an ultrasonic power device and an ultrasonic tumor therapy system; the ultrasonic power device comprises an ultrasound launch controller, an ultrasonic power source and a phase-shifting controller; the input end of the phase-shifting controller is connected with the ultrasound launch controller while the output end of the phase-shifting controller is connected with the ultrasonic power source. The ultrasonic tumor therapy system comprises a spherical crown body and at least one ultrasonic piezoelectric transducer including a piezoelectric chip arranged in the installation hole of the inner wall of the spherical crown body and at least one ultrasonic power device; the ultrasonic power device is respectively connected with the ultrasonic piezoelectric transducer in sequence. By switching the phase-shifting controller in the ultrasonic power device and using the phase-shifting controller to adjust the time delay which is sent out by the pulse of the ultrasonic power source to ensure the synchronization of the pulses sent out by different ultrasonic power sources, thereby guaranteeing that the energy focused by the spherical crown body can reach the largest state and thus improving the effectiveness of treatment.
