Improved ultrasonic therapeutic instrument

The utility model discloses an improved ultrasonic therapeutic instrument, comprising a host, a piezoelectric crystal plate, and a treatment head connected to the host, an LCD liquid crystal display screen positioned on the host, a drive unit driving the piezoelectric crystal plate to oscillate, a control unit connected to the LCD liquid crystal screen and the drive unit, a water pump and an air pump which are connected to the control unit, and a water tank storing sound conducting liquid. The piezoelectric crystal plate is arranged within the treatment head; the water pump is connected to the treatment head through a water pipe to form a circulation loop. The air pump is connected to the treatment head through an air pipe to guide the airflow into the treatment head; the control unit receives instructions from the LCD liquid crystal display screen to drive the piezoelectric crystal plate to oscillate and starts up the water pump and the air pump at the same time. The ultrasonic intensity of the improved ultrasonic therapeutic instrument reaches 140W/cm , so that, compared with the general small-size ultrasonic therapeutic instruments, the diseases having higher requirements for ultrasonic intensity can be treated well and the application is wide.
