Temperature modulated RF instrument generates a beam of very high frequency current between the temperature difference electrodes, the temperature difference electrodes are insulated throughout except for the tip, when the current passes through the temperature difference electrodes, the tissues around the electrodes (including the pain conducting nerve tissue) can be heated to a certain temperature to achieve blocking its conduction for analgesic purposes. Treatment method: Through percutaneous puncture, the temperature difference electrode emits current to stimulate the target nerve, and after establishing a safe position, a radiofrequency current (about 300 KHz) is given through the temperature difference electrode, resulting in the heating of the surrounding tissues in the target nerve (generally within 850C) and causing nerve conduction block. Indications: Suitable for cervical and lumbar small joint pain and pain of posterior spinal nerve branch origin, sacroiliac joint pain, trigeminal neuralgia, pterygopalatine neuralgia, and local pain point treatment.
