Abstract

An ultrasonic therapeutic device capable of multipoint transmitting includes a substrate (5), on which an ultrasonic transducer array is arranged. Wherein, each of the ultrasonic transducers in the ultrasonic transducer array can independently focus. The device of the present invention has a simple structure and a good focusing performance. There is no interference among the ultrasonic transducers. Therefore, the energy of ultrasonic wave is transmitted by predetermined route with high utilization ratio.
