Abstract
The invention relates to a diagnosis light source used for an endoscope and comprises a light guiding fibre bundle located in a clamp hole of the endoscope. The invention is characterized in that the diagnosis light source also comprises an excitation light source; a rotary table is arranged between the excitation light source and the light guiding fibre bundle; and the rotary table has at least two holes, at least one of which is provided with an optical filter. The excitation light source is a white xenon light source. As a preferable scheme, three holes are formed on the rotary table, wherein, optical filters with wavelength of 415nm and 540nm are respectively arranged on two holes. The invention has the advantages that an excitation light emitted by the white xenon light is added to a light source part of the traditional endoscope; two selected light beams with fixed wavelength can directly enter a human body through transmission fibers of the endoscope to excite the organism which needs to be detected; and the fluorescence tone of the lesion site and the blood vessel color change of the mucosa tissues can be observed through acquired images. Furthermore, the diagnosis of early tumor can be achieved by fluorescence curved line which is obtained through inserting feedback optical fibers into the clamp holes.
Description
Technical field
The present invention relates to the correlative technology field of Medical Devices, specifically a kind of diagnosis light source that is used for endoscope.
Background technology
The conventional endoscope inspection is to give the doctor by the strong illumination and the photo that will be examined tissue of making a video recording, judge the pathology situation by the doctor, this inspection is based on the doctor must abundant clinical experience, therefore a good endoscopic diagnosis doctor may be a fast pensioner people, also have the early stage instrument of original primary fluorescence to be based on the exciting light of the ultraviolet section wavelength of 300nm～400nm, can only transmit by silicon fiber at present, and silica fibre is easily broken, be not easy bending and be not suitable for conduction optical fiber as endoscope, can only insert optical fiber by the speculum forceps hole at present and transmit exciting light, but hinder the large-scale application of this instrument because of optical fiber is easily broken.
Summary of the invention
The purpose of this invention is to provide a kind of diagnosis light source that is used for endoscope, be used for cooperating the diagnosis infantile tumour.
For achieving the above object, the present invention has adopted following technical scheme:
The invention discloses a kind of diagnosis light source that is used for endoscope, comprise the fibre-optic bundle that is positioned at the speculum forceps hole, it is characterized in that: also comprise one road excitation source, be provided with a rotating disk between the input port of excitation source and fibre-optic bundle, rotating disk is provided with at least two holes, at least one hole is provided with optical filter, has a hole to be positioned on the light path at excitation source and fibre-optic bundle place all the time.
Described excitation source is white xenon source.
As a kind of preferred version, described rotating disk is provided with three holes, and two holes wherein are provided with optical filter.Described optical filter is respectively the optical filter of 415nm and 540nm wavelength.
The invention has the advantages that: the Lights section in conventional endoscope increases the exciting light that route white xenon lamp sends again, the light of getting two specific wavelengths directly enters human body by the endoscope Transmission Fibers and excites tested tissue, the blood vessel change in color of fluorescent colortone, the mucous membrane tissue of image viewing diseased region that can be by picked-up and diagnose infantile tumour by the variation that the feedback optical fiber that insert in the pincers hole is obtained fluorescence curve.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the structural representation of rotating disk of the present invention.
The specific embodiment
Below in conjunction with drawings and Examples the present invention is further described.
A kind of diagnosis light source that is used for endoscope, comprise the fibre-optic bundle 2 that is positioned at endoscope main body 1 pincers hole among Fig. 1,2, be arranged at the image unit 3 of body 1 front end, be arranged at the white xenon lamp excitation source 4 of body 1 end, and control module 5 and image-display units 6, be provided with a rotating disk 7 between the input port of excitation source 4 and fibre-optic bundle 2, rotating disk 7 is provided with three holes 8, is respectively equipped with the optical filter 9 of 415nm and 540nm wavelength on two holes wherein.Structure can realize the conversion of light sources with different wavelengths by electronic or manual form thus.
This installs first diagnostic method is with the camera system of endoscope the pathological tissue picture shooting under two kinds of wavelength light irradiation to be got off to judge examinee's precancerous lesion situation for the doctor by the image of display demonstration, another diagnostic method is a branch of optical fiber that one to some optical fibers are formed to be entered by the pincers road be close to tested tissue mucosa surface, exciting light shines the fluorescence information that tested tissue surface produces, after keyboard or floor push sampling, this signal shows by display through after the Computer Processing by fiber optic transmission output spectrum curve signal to the low light level fast spectral analysis modules OMA system again.
