The invention discloses a narrow-spectrum cervical examination instrument and a detection method thereof. The examination instrument comprises a sleeve, a lead-in assembly, a narrow-spectrum light-emitting assembly and an amplifying assembly, wherein the sleeve forms a conical cylinder with openings at two ends, and the taper of the conical cylinder is gradually increased from a first opening to asecond opening; a lead-in assembly can be inserted into the sleeve; the first end of the lead-in assembly extends out of the first opening, and the second end of the lead-in assembly can be clamped into the second opening; the narrow-spectrum light-emitting assembly is embedded in the outer wall of the second opening and enters an inner cavity of the sleeve, and four working modes of white light,blue light, green light and blue-green light can be adjusted through the narrow-spectrum light-emitting assembly; and an observation opening communicating with the inner cavity of the sleeve is formed in the top of the second opening, and the amplifying assembly is movably clamped to the second opening and can cover the observation opening. The narrow spectrum and the magnifying glass technologyare combined, light with the wavelength ranging from 400 nm to 600 nm is utilized and absorbed by capillaries on the surface of mucosa and capillaries below the surface layer of the mucosa respectively, distinct contrast is formed among normal mucosa, blood vessels and diseased regions, and the diagnosis sensitivity of cervical lesions is improved.
Description
technical field [0001] The invention relates to the technical field of gynecological clinical diagnostic instruments, and more specifically relates to a narrow-spectrum cervical examination instrument, which can perform narrow-spectrum (NB) detection on the cervix to increase the sensitivity of lesion identification, especially to improve the detection of cervical cancer Erosion of capillary changes, diagnostic rate of early cancer screening. Background technique [0002] The inspection of the cervix and vagina directly through the vagina is one of the common inspection items in gynecology. Through this inspection, the situation of the cervix and vagina can be directly and clearly understood, and gynecological diseases related to the cervix can be diagnosed. Diagnosis, early treatment; Cervical examination is divided into conventional vaginal speculum examination and colposcopy, but the existing examination methods are all under white light and naked eye conditions for discr...
