The one-off cervix aspiration biopsy pincers of band light source of the present utility model comprise a white light source and a blue light source, and tool has the following advantages:
First, the feature of white light source is as follows:
(1) (common white light LED particle color rendering index Ra is 65-70 to the white light of high color rendering index (CRI), the Ra>90 of the white light source in this utility model), because different tissues in body has different wavelength reflection characteristics, therefore adopt the light source of high color rendering index (CRI), make the resolution of doctor to in-vivo tissue more clear, (2) white light source its saturated red (special colour rendering index R9) that this utility model is selected is greater than 0, therefore compared to common LED light source, it comprises more red color light component, inside of human body tissue (is mainly taken on a red color, namely to HONGGUANG, there is hyper spectral reflectance) when irradiating, reflectance lightness is higher, and luminance contrast is also more strong, the nuance telling tissue that doctor is more prone to, (3) white light source that this utility model is selected has the characteristic of low colour temperature, royal purple light component in radiation of light source spectrum is less compared to ordinary light source, the tissue that may be used for the long period due to white light source is irradiated, and the verified long royal purple light of the research of photo bio safety has larger injury for tissue and form international standard (IEC 62471), therefore white light source is more suitable for the long-time illumination of tissue examination compared to other light sources, (4) white light source that this utility model is selected also has the advantage of pole low-infrared radiation compared to halogen tungsten lamp spotlighting mode common in medical detection, the verified long infrared radiation of research (wavelength 780nm-1mm) of photo bio safety can cause skin burn, wherein near infrared band (780-1400nm) is as injected human eye, cataract and retinal burn can be caused, middle-infrared band (1.4um-3um) can cause cataract and ambustio corneae, far infrared (3um-1mm) can cause ambustio corneae, due to the white light source pole low-infrared radiation characteristic that this utility model is selected, the white light source that this utility model is selected is safer in medical detection,
Secondly, the feature of this utility model blue light source is as follows:
Fluoroscopy is that a kind of women's genital system diseases checks diagnostic method, and more objective than traditional observation method of naked eye, sensitivity is higher, and utility model is stronger.Improve the accuracy of gynecologial examination result, be conducive to timely diagnose medical conditions, play the effect of early treatment early rehabilitation.The shortcoming of conventional fluorescent inspection technique (VIA) is that the white reflective that Dichlorodiphenyl Acetate reacts in vain under incandescent source is not obvious, and rate of missed diagnosis is very high.
The shortcoming tested in conjunction with VIA and advantage improve on the basis of traditional VIA, change incandescent source is the white fluorescence light source of opaque indigo plant, and fluorescence light source is arranged in a wavelength range, reflection is there is and produces white in abnormal cervical hyperplastic tissue to fluorescence, react in conjunction with acetic acid albefaction simultaneously, pathological changes position, the border, position of pathological changes and profile can be found intuitively by the change on local color and pathological changes border, the advantages such as false negative rate is extremely low, reduce mistaken diagnosis and rate of missed diagnosis, improve the diagnosis to cervical cancer and precancerous lesion.
The blue light source that this utility model is selected is that a peak wavelength is at 460-470nm, the ultra-blue-light of half width (FWHM) 20-35nm, the mechanism using it for tissue inspection is that pathological tissues is under the effect of acetum, the reflectance of corresponding blue wave band has larger difference compared to the blue wave band reflectance of normal structure, make the brightness of pathological tissues and normal structure occur larger difference, be easier to doctor and distinguish; Its novelty is the peculiar spectrum reflection characteristic utilizing pathological tissues, by using up to inspection the characteristic spectrum composition that with the addition of pathological tissues, makes pathological tissues be easier to identification.
Generally speaking, the light source of the one-off cervix aspiration biopsy pincers of band light source of the present utility model is made up of two light source, a white light source, and a blue light source, integrates and say to have following features:
(1) photon radiation of high energy quantum is filtered, completely to human body fanout free region.Owing to removing the royal purple light component in spectrum comprehensively, really realize harmless irradiation.
(2) color rendering index is high, and the high color rendering index (CRI) of lighting source is conducive to doctor and differentiates trickle tissue color difference.Light source of the present utility model have employed HONGGUANG, green light band supplements technology, makes it have the color rendering index (general lighting LED color rendering index Ra=65 ~ 70, Ra>90 of the present utility model) far above general lighting LED.
(3) promote visual field details identification, prevent dazzling, when there is higher source luminance in the visual field, because the luminance dynamic range of human eye is limited, minimum brightness threshold value increases, and makes human eye cannot distinguish detailed information in the visual field.Light illumination end of the present utility model is preposition, and without backward luminous, make to only have irradiated tissue in the doctor visual field, gauge without light source light direct beam is pleasing to the eye, thus improves the details identification in the doctor visual field.
(4) short distance large scale hot spot, common LED light-emitting mode is that Lang Bo body is luminous, forms at illuminated tissue the Illumination Distribution that center is bright, edge is dark.Light source of the present utility model adopts Random Curved Surface Designing, makes illuminated tissue remain within the scope of very large irradiation hot spot, keeps illumination consistent, is conducive to doctor and observes pathological tissues more comprehensively.
5. all there is the spatial non-uniformity of colourity in general lighting light source, and namely in illumination zone, the color of diverse location there are differences, and in operation process, the uneven type of colourity very easily causes doctor to the erroneous judgement of lesion tissue.Light source of the present utility model, by fluorescent material paint-on technique, makes plane of illumination no color differnece, is easier to the accurate judgement of doctor to pathological tissues.
6. realize the heat dissipation technology of constant temperature cold light source, ordinary light source caloric value is large, and infrared spectrum composition is high, easily causes tissue burn or ambient temperature to raise.The specular removal chip of light source of the present utility model (with disposable sterilized vaginal dilator with the use of Medical Cold Light Source 140lm/W, electric filament lamp 10lm/W) combine the heat conduction analysis of carrying out based on aerodynamic heat loss through convection and FInite Element, make the heat affecting of light source to tissue and environment be zero.
Above-described embodiment is one of the present utility model preferably scheme, not does any pro forma restriction to this utility model, also has other variant and change under the prerequisite not exceeding the technical scheme described in claim.
