Abstract

A photodynamic therapy device for cervical and vaginal early cancer and precancerous lesions, which includes an insertion tube, a stretching balloon, and a light-emitting structure; it is characterized in that a stretcher for stretching the vagina is arranged on the outside of the insertion tube The balloon is stretched to extend the filling tube; the filling tube is connected to the filling structure; the tube extending into the tube is provided with a light-emitting structure that emits light of a therapeutic wavelength; the balloon is stretched, and the tube is set as a transparent structure; The light emitting structure is connected with the light generator. When in use, when the balloon is not inflated, the balloon is close to the insertion tube and enters the appropriate position of the vagina with the insertion tube, and then the vagina is propped up by filling the balloon with gas or liquid to support the vaginal folds Open to prevent partial parts of the occlusion; when propped up, it can also achieve effective exposure of the entire cervix to prevent occlusion; after the light generator is turned on, the light-emitting structure extends into the designated position through the insertion tube for photodynamic therapy.

Description

technical field [0001] The invention belongs to the technical field of tumor devices, and in particular relates to a device for treating cervical cancer and vaginal cancer, in particular to a photodynamic therapy device for cervical and vaginal early cancer and precancerous lesions. Background technique [0002] Worldwide, there are about 530,000 new cases of cervical cancer every year, more than 85% of cervical cancer cases occur in developing countries, and about 50% of cases occur in Asia. The 5-year survival rate of cervical cancer is only 44-66%. The number of new cases in my country is about 150,000 per year, accounting for about 1 / 3 of the world's total, and about 30,000 to 50,000 women die of cervical cancer every year. It has been confirmed that persistent high-risk HPV infection is a necessary condition for cervical cancer; persistent infection and high load of high-risk HPV are closely related to cervical intraepithelial neoplasia (CIN). [0003] The traditional...
