Problems solved by technology

[0006] There are some limitations in the existing three-step model: first, it is carried out in three steps, with many links, long time, great uncertainty, and greater psychological pressure on patients
Second, the final diagnosis depends on pathological biopsy, but biopsy is damaged, and the point

Embodiment Construction

[0034] The specific embodiment of the present invention sees figure 1 :

[0035] Technical scheme of the present invention is:

[0036] An optical scanning probe for gynecological examinations, such as figure 1 , including a collimating mirror 2, a reflecting mirror 3, a scanning galvanometer 4 and a probe tube 5, the collimating mirror 2 is connected to the optical fiber 1, and the divergent beam emitted by the optical fiber 1 is refracted by the collimating lens of the collimating mirror 2 to form Near parallel light, the near parallel light emitted by the collimating mirror 2 is reflected by the reflector 3 and the scanning vibrating mirror 4 successively and enters the probe tube 5, the surface of the scanning vibrating mirror 4 is a flat mirror coated with a high reflection film, and the probe Three lenses 6 are arranged in the tube 5, and an inclined window is arranged at the tail of the probe tube. 7 is a plano-convex lens whose inner side is convex and the outer sid...

Abstract

The invention discloses an optical scanning probe for gynecologic examination and a working method thereof. The optical scanning probe comprises a collimating mirror, a scanning galvanometer and a probe tube, wherein the collimating mirror is connected with an optical fiber, light emitted by the collimating mirror is reflected by the scanning galvanometer to enter the probe tube, 2n+1 lenses are arranged in the probe tube, the tail of the probe tube is provided with an inclined port in seal connection with an inclined window, and the window is a plano-convex lens. The probe has ultrahigh resolution; cell-level imaging of in-vivo cervical tissues is realized for the first time; aberration is reduced to a great extent and resolution is improved by using the planoconvex lens as the window; and an annular scanning two-dimensional galvanometer is adopted as the scanning galvanometer, so that sudden acceleration and deceleration are avoided through annular scanning, and a larger effective imaging area is achieved under the same hardware condition (such as the clear aperture).

Description

technical field [0001] The invention relates to the technical field of cervical examination, in particular to an optical scanning probe for gynecological examination and its working method. Background technique [0002] Cervical cancer is the third most common malignant tumor in women in the world and the second most common malignant tumor in Chinese women. According to the World Health Organization (WHO), there are more than 470,000 new cases of cervical cancer in the world every year, and China accounts for 28%. Without proper and effective screening methods and preventive measures, the incidence of cervical cancer in Asia will increase by 40% by 2025. [0003] Human papillomavirus (HPV) is the culprit that causes cervical cancer. It is an extremely common virus. Up to 75% of women will be infected with HPV at some point in their lives. Most women can rely on their own immunity to get rid of the virus. However, if the HPV is continuously infected for a long time and the ...
