Problems solved by technology
[0003] 1. What is obtained is the autofluorescence of the tissue, the luminescence is weak, and the difference between the diseased tissue and the normal tissue is not obvious, which affects the diagnosis
[0004] 2. Autofluorescence is easily interfered by the thickness of the local stratum corneum and the inflammatory state of the lesion, and the false positive and false negative rates are high
[0005] 3. It is impossible to obtain white light and fluorescence images of diseased tissue at the same time, which is inconvenient for tracking comparison and lesion range scanning

The invention discloses an oral mucosainduced fluorescence detection and diagnosticapparatus. The apparatus comprises a cylinder body, a camera device and a photosensitizer for inducing fluorescence,the cylinder body is opened at one end, a through hole is formedin the other end,the inner wall of the cylinder body is provided with atrigger light source and an illumination light source, and the camera device includes a display screen. The apparatus can induce tissue fluorescence, and achieve early diagnosis, differential diagnosis and curative effect follow-up visits of oral mucosal diseases,especially cancerous changes of oral mucosal potential malignant diseases according to the imaging of the fluorescence and the changes of imaging properties thereof.
Description
technical field [0001] The invention relates to the field of medical instruments, in particular to an oral mucosa-induced fluorescence detection and diagnosis instrument. Background technique [0002] Fluorescence diagnosis has become a commonly used auxiliary diagnostic method for oral mucosal diseases, especially for potential malignant diseases of the oral mucosa. The existing fluorescent oral detection device irradiates the tissue with a fluorescent lamp in the cylinder, and then uses a camera device to take pictures of the tissue through the cylinder. and display. This device mainly has the following deficiencies: [0003] 1. What is obtained is the autofluorescence of the tissue, the luminescence is weak, and the difference between the diseased tissue and the normal tissue is not obvious, which affects the diagnosis. [0004] 2. Autofluorescence is easily interfered by the thickness of the local stratum corneum and the inflammatory state of the lesion, and the false ...
