Abstract

The invention discloses photodynamic therapy equipment for cervical and vaginal early cancer and precancerous lesions. The photodynamic therapy equipment comprises an extension tube, a expansion balloon and a light-emitting structure, the equipment is characterized in that the expansion balloon for expanding vagina is arranged on the outer side of the extension tube, a filling tube extends out ofthe expansion balloon, a filling pipe is connected with a filling structure, a light-emitting structure for emitting treatment wavelength light is arranged in the extension tube, the expansion balloonand the extension tube are of transparent structures, and a light generator is connected with light-emitting structure. During use, when the balloon is not inflated, the balloon clings to the extension tube and enters a proper position of the vagina along with the extension tube, and then the balloon is inflated with gas or liquid to expand the vagina, so that vagina wrinkles are expanded, partial parts are prevented from being shielded, a whole cervix opening can be effectively exposed when expansion, the shielding is prevented, then the light generator is turned on, and the light-emitting structure extends into a designated position through the extending tube to carry out 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...
