A kind of long-distance intelligent optical biopsy diagnostic equipmentTechnical field
The present invention relates to a kind of long-distance intelligent optical biopsy diagnostic equipment, in particular for the diagnosis of mucosal pattern early diagnosis of cancerInstrument.
Background technology
At present, optical biopsy precancerous lesion image diagnostic instrument is disclosed in Chinese patent CN85100424, using black lightAs exciting light, surface of living body tissue is transferred to through silicon fiber, the biological tissue is excited its primary fluorescence of generation.It is rightIn malignant tumour, can inspire its aberration can use the primary fluorescence of discernable by eye.The diagnostic method is easy to operate, rapid, losslessWound, and cost is low, detection accuracy rate is high, and the early stage property tumour such as the oral cavity that is particularly suitable for use in, cervix, vagina, anal tube, rectum is generalLook into.
Chinese patent ZL00216974.6 discloses a kind of diagnostic equipment light supply apparatus, and it is constituted including structure in detail below substantiallyPart：Cabinet, is vertically arranged the excitation lamp for providing exciting light, the illuminating lamp for providing illumination light, reflection black lightReflector, colour filter, condenser lens, its position relationship is：The light sent by excitation lamp is through reflector reflecting focal, colour filterInjection is transmitted through the fiber to be checked group positioned at the optical fiber head of its focal plane focal position after the light line focus lens focus of filteringKnit.The light supply apparatus of natural fluorscence diagnosis instrument used for diagnosising malignant tumour is contributed.
But still there is blemish in an otherwise perfect thing in existing diagnostic equipment：
1. the unadjustable property of light source output energy, energy is too strong when early stage is used, strong photobleaching mucosal tissue fluorescence effectShould, influence inspection result.
2. the later stage causes the fluorescent effect of mucosal tissue unobvious using energy decline, doctor is difficult to accurately determine whether toChange light supply apparatus.
3. light source has been at full power and used, energy of light source wastes serious, and light source life is short.
4. excitation lamp position is put, fixation is unadjustable, and reflector, the product error of condenser lens and alignment error can influence defeatedThe energy of light source gone out.
5. video camera fixes unadjustable, big is influenceed on the picture quality shot, remote control is particularly disadvantageous for.
Therefore, in implementation process, if it is rationally distributed to design a kind of functional structure, man-machine environment is met, operation makesWith convenient, and beneficial to remote control and the long-distance intelligent optical biopsy diagnostic equipment of diagnosis, it will effectively promote early stage property tumourThe development of census operations.
