Portable cervical cancer precancerosis diagnostic equipment

Abstract

The invention discloses a piece of cervical cancer precancerosis diagnostic equipment, comprising a cervical cancer inherent fluorescence detecting system, a uterine cervix acetic coloring detecting system, an image acquisition system and an external image processing system; wherein, the cervical cancer inherent fluorescence detecting system comprises a light source and a switch of the light source, and the light source includes an excitation light source for providing fluorescence and a cold light source for providing white light which are both installed in a reflection bowl with a specific focal distance; the uterine cervix acetic coloring detecting system comprises an acetic acid pool, a spray pipe connected to the acetic acid pool, a shift device of the spray pipe and a spray switch; the image acquisition system comprises a dim light CCD which is installed at the center of the reflection bowl; the image acquisition system is connected with an external image processing system whichcan process the images collected by the image acquisition system; the uterine cervix is sequentially irradiated by white light and excitation light and the images of the white light and the excitation light reflected by the uterine cervix are collected; the acetic acid is sprayed on the uterine cervix which is irradiated by the white light and the excitation light after waiting for a moment and the images of the white light and the excitation light reflected by the uterine cervix which is sprayed with the acetic acid are collected.

Description

technical field [0001] The present invention relates to a device for diagnosing precancerous lesions, and more particularly, to a diagnostic device for rapid screening or standard detection of cervical precancerous lesions. Background technique [0002] One of the main reasons for the high mortality rate of cancer in the world is that there is no major breakthrough in diagnostics, and diagnostic methods still remain in gross morphology. Such as the doctor's experience, colposcopy, endoscopy, B-ultrasound, CT, MRI and other gross morphological diagnostic methods, such diagnostic methods are still difficult to differential diagnosis for small cancers less than 0.5cm. And because the source of disease of epithelial cancer all originates in the epithelium (ie mucous membrane), because it does not yet break through the epithelial layer (mucosa) to form all the characteristics of cancer, so it is called precancerous lesion. Take cervical precancerous lesions (CIN for short) as an...

AI Technical Summary

Problems solved by technology

CIN is a cell and biochemical change in the epithelium (mucosa), and it is difficult to display valuable information on the outer layer of the epithelium (mucosa). It has detection and diagnosis value, but the detection rate of CIN is low

[0004] Visual observation of VIA after staining with acetic acid is of certain value for the detection of CIN. The cervix smeared with acetic acid can show metaplastic epithelium and poorly differentiated epithelium. They all show white plaques. These white plaques may be CIN lesions, but The positive detection rate of CIN is about 40%.
