[0002] With the rapid development of science and technology in the medical field in recent years, non-invasive ultrasound operation and treatment has gradually become an important means of clinical diagnosis and treatment. High-intensity focused ultrasound (HIFU) is a non-invasive, radiation-free treatment technology that can preserve the structure and function of limb organs. It focuses ultrasound on the target tissue, and uses the tissue penetration and energy deposition of ultrasound to focus the ultrasound generated outside the body on the diseased tissue (therapeutic target) in the body. Through the mechanical effect, thermal effect and cavitation effect of ultrasound, the temperature of the tissue in the target area rises sharply to 65℃-100℃ within a few seconds, and the target tissue instantly undergoes coagulative necrosis without damaging the tissue outside the target area, thereby achieving the purpose of precise treatment of diseases, especially in tumor ablation treatment. Significant results have been achieved.

[0003] Despite its many advantages, existing HIFU devices still have certain limitations in terms of focusing accuracy and control range. Complications such as skin damage caused by ultrasonic energy passing through skin tissue during patient treatment cannot be completely avoided, often causing pain, blisters, and sequelae such as rough skin, skin collapse, uneven skin, and even scars due to damage to the stratum corneum. These sequelae make postoperative care, recovery, and smooth discharge difficult.

After a sufficient temperature difference is generated between the conductive medium 31 and the skin, the condensation device 33 stops working, and the conductive medium 31 can absorb the heat of the skin to reduce the temperature of the skin. After the conductive medium 31 absorbs heat and rises to a temperature exceeding the preset temperature, the condensation device 33 works again to reduce the temperature of the conductive medium 31, and this cycle is repeated until the skin temperature drops below the preset value. Step S5: After the focused ultrasound treatment operation is completed, the power supply of the temperature control device is turned off, and the patient removes the temperature control device for full disinfection and equipment maintenance.

[0031] Preferably, in step S1, the temperature of the operating room for focused ultrasound treatment is first adjusted to a specified temperature. If the patient's affected area is found to be covered with hair, the skin needs to be prepared to fully expose the affected skin. When the patient wears the device, the center of the container of the liquid temperature control unit 3 needs to be aligned with the center of the ultrasonic energy beam irradiation area as much as possible to avoid the temperature sensing element 32 and the condensation device 33 blocking the path of the focused ultrasound. In step S5, after the focused ultrasound treatment operation is completed, the temperature control device is not turned off immediately. Wait until the patient lies quietly and rests until he wakes up or the skin temperature of the treatment area reaches the preset temperature and stabilizes for at least 20 minutes before turning off the power of the temperature control device to ensure that the skin in the treatment area is fully cooled to achieve a protective effect.
