During treatment, the ultrasonic generator 1 emits ultrasonic waves, and the ultrasonic waves are focused to form a treatment point. When the treatment point needs to move, the PLC sends a signal to make the X, Y, and Z-axis stepper motors drive the moving device to move. With the cooperation of the grating rulers of each axis, the treatment point is accurately moved to the optimal treatment position on the lesion.
