The temperature sensing element 13 comprises, for example, a thermocouple, a thermistor, a semiconductor temperature sensing element or a fiber optic temperature measuring element. By returning the temperature sensed by the temperature sensing element 13 to a processing module, feedback control can be performed to achieve the temperature control effect. In this way, the entire treatment process can be controlled at a fixed temperature, or the desired temperature can be adjusted at any time to improve the therapeutic efficiency.
