Ultrasonic treatment head with crystal oscillator, ultrasonic treatment equipment and driving method

The invention discloses an ultrasonic treatment head with a crystal oscillator, ultrasonic treatment equipment and a driving method, the ultrasonic treatment head with the crystal oscillator comprises a treatment head body, and the treatment head body comprises the crystal oscillator which is used for outputting an excitation clock signal consistent with the resonant frequency of an ultrasonic transducer in the treatment head body and sending the excitation clock signal to an ultrasonic treatment host; and the ultrasonic transducer is used for receiving a driving signal obtained after the excitation clock signal sent by the crystal oscillator is processed by an ultrasonic treatment host so as to output an ultrasonic pulse. The invention further comprises the ultrasonic treatment equipment and a driving method. According to the invention, corresponding accurate frequency excitation can be carried out on each transducer, the electro-acoustic conversion efficiency is greatly improved, the circuit is simple and r
