[0002] The ultrasonic electrode head is a key component in ultrasonic therapy equipment, and is mainly used to convert electrical energy into mechanical vibration energy to achieve therapeutic purposes. Ultrasonic therapy uses the mechanical and thermal effects of high-frequency sound waves to treat tissues. Mechanical vibration can promote cell metabolism, and thermal effects can increase tissue temperature, promote blood circulation, and relieve pain and inflammation. The design of the ultrasonic electrode head usually uses piezoelectric materials (such as piezoelectric ceramics). These materials can generate mechanical vibrations under the action of an electric field. The core of the electrode head is the transducer, which converts electrical energy into mechanical energy. Ultrasonic electrode heads are widely used in ultrasonic physiotherapy, ultrasonic surgery, ultrasonic drug delivery, and beauty.
