Therefore, pulsed radiofrequency technology has gradually been widely used in clinical pain treatment. In actual use, medical radiofrequency needles will be used. When treating superficial parts of patients, the length of the radiofrequency needle or the lack of short radiofrequency cannula needles and radiofrequency electrodes in the department may cause the needle to fall off, requiring medical staff to manually support the radiofrequency needle to cooperate in completing the treatment process.
