Description

Narrow spectrum cervical examination instrument and detection method thereof

technical field

The invention relates to the technical field of gynecological clinical diagnostic instruments, and more particularly to a narrow-spectrum cervical examination instrument, which can perform narrow-spectrum (NB) detection on the cervix, so as to increase the sensitivity of the identification of lesions, especially to improve Erosion of capillary changes, diagnostic rate of early cancer screening.

Background technique

Direct observation of the cervix through the vagina is one of the common inspection items in gynecology. Through this inspection, you can directly and clearly understand the situation of the cervix and vagina, diagnose gynecological diseases related to the cervix, and achieve early detection and early detection. Diagnosis and early treatment; cervical examination is divided into routine vaginal speculum examination and colposcopy examination, but the existing inspection methods are all judged under the conditions of white light and naked eye, but relying on the naked eye to observe and diagnose the lesion site, the rate of missed diagnosis and misjudgment higher rate.

Through research, it has been found that the narrow-spectrum NB technology can improve the contrast and clearly display the superficial microvascular morphology and fine surface structure of the mucosa. There are four principles:

1. The main substance that absorbs visible light in the mucosa is hemoglobin, which absorbs the blue light of 415 nm and the green light of 540 nm most obviously. Therefore, the blood vessels under NB are dark and have strong contrast.

2. The wavelengths of these two kinds of light are short, and their penetration to the mucosa is weak. They are reflected on the mucosal surface and superficial layer, and can display the superficial microvascular structure.

3. Light is strongly reflected on the surface of the mucosal epithelium, which can better display the surface morphology of the mucosa.

4. Narrow-spectrum light sources help improve contrast.

Therefore, how to provide a narrow-spectrum cervical examination instrument to facilitate observation and diagnosis and reduce the rate of missed diagnosis and misjudgment is an urgent problem to be solved by those skilled in the art.
