[0002] Oral ulcers, also known as mouth sores, are a common oral mucosal disease. They often appear on the mucosa of the lips, palate, tongue and cheeks in the mouth, and are round or oval painful ulcers. Various factors such as genetics, diet, and decreased immunity may induce the development of oral ulcers. About 10%-25% of the population in my country suffers from recurrent oral ulcers. The treatment measures for oral ulcers are mainly local anti-inflammatory, pain relief, and promotion of ulcer healing. Systemic treatments mostly extend the interval period. Treatment is based on the severity of the ulcer and the patient's wishes. The main methods include local medication, systemic medication, and physical therapy.

[0003] Among them, local drug treatment requires targeted application of medicine to the affected area, such as a multifunctional oral mucosa auxiliary medicine application device with announcement number CN213941833U, which includes a bracket, a tongue depressor, a lamp tube, a lamp bead and a battery. The tongue depressor is fixedly connected to the bracket, the lamp tube is arranged on the side of the bracket away from the tongue depressor, the lamp bead is arranged at the end of the lamp tube close to the tongue depressor, a battery cavity is opened inside the lamp tube, the battery is located inside the battery cavity of the lamp tube, and the lamp bead is electrically connected to the battery. The lighting device composed of the lamp tube, the lamp bead and the battery in the above-mentioned prior art emits light to realize illumination of the inside of the oral cavity during operation, which can expand the range of illumination and make the operation more convenient, especially suitable for the operation of applying medicine on the lower lip of the oral cavity and deep in the oral cavity; the above-mentioned prior art is provided with an adjustable ruler at the front end, and the radius radiating outward from the center of the ulcer can be measured relatively accurately through the ruler, or the range of the ulcer lesion can be measured, which is convenient for accurate drug administration and adjustment of the treatment plan.

[0004] However, the above-mentioned prior art still has some defects when applying medicine for oral mucosal ulcers: 1. The above-mentioned prior art realizes the illumination of the inside of the oral cavity during operation by means of a lighting device, and completes the change of the light irradiation angle in the oral cavity by means of a reflector, which can expand the range of illumination and make the operation more convenient, but it is not convenient to apply the medicine due to the obstruction of the lighting device during illumination, and there is still room for improvement.
