It can be understood that the front end of the catheter portion 1 is provided with a lens 4; and

[0049] The electrode ring 2 is mounted on the outer tube 12. A plurality of electrode rings 2 are provided, and the plurality of electrode rings 2 are arranged in sequence along the length of the outer tube 12. Each electrode ring 2 is capable of independent discharge. Independent discharge can be understood as each electrode ring 2 being able to operate and be controlled independently, and each electrode ring 2 being able to independently transmit electrical stimulation signals.

[0050] Therefore, when the catheter part 1 is inserted into the pharynx or pharyngeal cavity, the lens 4 can visually observe the condition of the pharynx or pharyngeal cavity, forming an endoscopic window or endoscopic lens, which makes the insertion smoother, reduces the stuck points, and can be inserted more accurately to the position or affected area to be treated, and can basically reach the designated affected area in one go, thereby reducing the patient's pain and other discomfort and improving the treatment effect.

[0051] In addition, multiple electrode rings 2 are provided and are capable of independently discharging. Various types of discharge treatments can be performed according to the treatment plan of the disease or the corresponding positions of each affected area. For example, any one or any multiple electrode rings 2 can be selected for discharge treatment of nerve stimulation, thereby improving functionality and improving treatment effects.

[0052] In addition, the catheter part 1 is configured as a double-layer tube structure, the inner tube 11 is used to set the lens 4, and the outer tube 12 is used to set the electrode ring 2. The inner tube 11 has less contact with the patient and can be recycled, thereby saving costs.
