One-off cervix aspiration biopsy pincers with light source of the invention include a white light source and a blue light source, have
Have the following advantages：
First, it is as follows the characteristics of white light source：
（1）The white light of high color rendering index (CRI)（Common white light LED particle colour rendering index Ra is 65-70, the white light light in the present invention
The Ra in source>90）, because internal different tissues have different wavelength reflection characteristics, therefore using the light source of high color rendering index (CRI), make
Resolution of the doctor to in-vivo tissue becomes apparent from；（2）Its saturation of the white light source of present invention selection is red（Special colour rendering index R9）
More than 0, therefore compared to common LED light source, it comprises more red color light components, to inside of human body tissue（Mainly in red
Color, i.e., have hyper spectral reflectance to feux rouges）When being irradiated, reflectance lightness is higher, and luminance contrast is also more strong, makes
What doctor can be more prone to tells the nuance of tissue；（3）The white light source that the present invention is selected has the spy of low colour temperature
Property, blue violet light composition in radiation of light source spectrum is less compared to ordinary light source, because white light source is possibly used for the long period
Tissue irradiation, and the research of photo-biological safety to have confirmed that prolonged blue violet light has for tissue larger
Injure and formed international standard（IEC 62471）, therefore white light source compared to other light sources be more suitable for tissue examination it is long when
Between illuminate；（4）The white light source that the present invention is selected also has compared to halogen tungsten lamp concentration illumination mode common in medical detection
The advantage of extremely low infra-red radiation, the research of photo-biological safety has confirmed prolonged infrared radiation（Wavelength 780nm-1mm）Can
Cause skin burn, wherein near infrared band（780-1400nm）Human eye is such as injected, cataract and retinal burn can be caused, in
Infrared band（1.4um-3um）Cataract and ambustio corneae, far infrared can be caused（3um-1mm）Ambustio corneae can be caused, due to
The present invention select the extremely low infrared signature of white light source so that the present invention select white light source in medical detection more
Safety；
Secondly, it is as follows the characteristics of blue light source of the invention：
Fluoroscopy is that a kind of women's genital system diseases check diagnostic method, more objective than traditional observation method of naked eye
See, sensitivity is higher, and invention is stronger.The accuracy of gynecologial examination result is improved, is conducive to diagnosing illness in time, play early controlling
Treat the effect of early rehabilitation.Conventional fluorescent inspection technique（VIA）Shortcoming be under incandescent source Dichlorodiphenyl Acetate in vain reaction white reflective
Not substantially, rate of missed diagnosis is very high.
The shortcoming and advantage tested with reference to VIA are improved on the basis of traditional VIA, become incandescent source into non-reflective
Blue white fluorescence light source, and fluorescence light source is arranged in a wavelength range, abnormal cervical hyperplastic tissue occurs anti-to fluorescence
Penetrate and produce white, in combination with acetic acid albefaction reaction, disease can intuitively be found by the change on local color and lesion border
Become position, the position border of lesion and profile, the advantages of false negative rate is extremely low, reduce mistaken diagnosis and rate of missed diagnosis, it is right to improve
The diagnosis of cervical carcinoma and precancerous lesion.
The blue light source that the present invention is selected is a peak wavelength in 460-470nm, half width（FWHM）The list of 20-35nm
Color blue light, the mechanism for using it for tissue inspection be pathological tissues in the presence of acetum, corresponding blue light ripple
Section reflectivity there is larger difference compared to the blue wave band reflectivity of normal structure, make the brightness of pathological tissues with it is normal
There is larger difference in tissue, it is easier to which doctor is distinguished；Its novelty is to be reflected using the peculiar spectrum of pathological tissues
Characteristic, uses up the characteristic spectrum composition that with the addition of pathological tissues so that pathological tissues are easier to identification by inspection.
Sum it up, the light source of the one-off cervix aspiration biopsy pincers with light source of the invention is made up of double light sources, one
White light source a, blue light source, integrates and says with following features：
（1）The radiation of high energy quantum photonic is filtered completely, to human body fanout free region.Due to removing the blue violet light in spectrum comprehensively
Composition, really realizes harmless irradiation.
（2）Colour rendering index is high, and the high color rendering index (CRI) of lighting source is conducive to the doctor to carry out trickle tissue color difference
Differentiate.Light source of the invention employs feux rouges, green light band complementary technology, makes it have the colour developing far above general lighting LED
Index（General lighting LED colour rendering indexs Ra=65 ~ 70, Ra of the invention>90）.
（3）Lifting visual field details identification, prevents dazzling, bright due to human eye when there is higher source luminance in the visual field
Degree dynamic range is limited, minimum brightness threshold value increase so that human eye cannot distinguish the detailed information in the visual field.Light source of the invention
Illumination end is preposition, without backward luminous, makes there was only illuminated tissue in the doctor visual field, and gauge without light source light direct beam is pleasing to the eye, so as to improve
Details identification in the doctor visual field.
（4）Short distance large scale hot spot, common LED light-emitting mode is luminous for Lang Bo bodies, in the formation of illuminated tissue
The Illumination Distribution that the heart is bright, edge is dark.Light source of the invention uses Random Curved Surface Designing, illuminated tissue is maintained at very big photograph
Penetrate in the range of hot spot, keep illumination consistent, be conducive to doctor more comprehensively to observe pathological tissues.
5. the color that general lighting light source has diverse location in the spatial non-uniformity of colourity, i.e. illumination zone is deposited
In difference, in surgical procedure, the uneven type of colourity easily causes erroneous judgement of the doctor to lesion tissue.Light source of the invention leads to
Fluorescent material paint-on technique is crossed, makes plane of illumination no color differnece, it is easier to accurate judgement of the doctor to pathological tissues.
6. the heat dissipation technology of constant temperature cold light source is realized, ordinary light source caloric value is big, and infrared spectrum composition is high, easily causes tissue
Burn or environment temperature is raised.The specular removal chip of light source of the invention（Used cooperatively with disposable sterilized vaginal dilator
Medical Cold Light Source 140lm/W, incandescent lamp 10lm/W）With reference to what is carried out based on aerodynamic heat loss through convection and FInite Element
Heat conduction analysis so that heat affecting of the light source to tissue and environment is zero.
Embodiment described above is a kind of preferably scheme of the invention, not makees any formal to the present invention
Limitation, also has other variants and changes on the premise of without departing from the technical scheme described in claim.
