Laser-induced fluorescence spectrum colposcope

Abstract

The invention discloses a laser-induced fluorescence spectrum colposcope. The invention uses laser light as the light source for inducing fluorescence, controls the laser scanning component to scan the cervical tissue site point by point, detects the excited fluorescence spectrum synchronously, and analyzes the correlation between the point-by-point acquired spectrum and the characteristic spectrum of the lesion to calculate the point-by-point lesion index , and then generate a lesion index distribution map. The invention can assist medical personnel to complete the detection process by adding an illumination source, an image sensor and the like. The laser scanning component, the spectrum acquisition component, the illumination source, and the image sensor realize light beam combining through the optical path beam combining component, and communicate the light with the lesion site through the positioning intubation tube. The invention utilizes the characteristics of high brightness, monochromaticity, and good directionality of laser light to irradiate the lesion with small spot area, high brightness, and high detection sensitivity. At the same time, it can excite laser-induced fluorescence specific spectra, greatly improving detection sensitivity and accuracy. .

Description

technical field [0001] The invention belongs to the field of medical testing equipment, and more specifically relates to a colposcopy testing equipment that uses a laser scanner to excite laser-induced fluorescence and acquires characteristic spectra of cervical tissue. Background technique [0002] Cervical cancer is the second most common cancer in women. The occurrence of cervical cancer is related to the infection of human papillomavirus (HPV). Some patients with high-risk HPV infection are prone to precancerous lesions and cervical cancer when they are persistently infected. [0003] Cervical cancer is one of the few malignancies for which morbidity and mortality can be reduced through prevention. At present, the standard process of diagnosing cervical cancer is to find suspicious lesions through colposcopy, and take biopsies of suspicious lesions to make pathological sections for diagnosis. Ordinary electronic colposcopy has average sensitivity and specificity in dete...

Problems solved by technology

[0006] The traditional fluorescence detection method uses xenon lamp or LED as the light source, which leads to large heat loss, poor imaging effect and low detection accuracy.
