Description
Technical field
The present invention relates to a kind of medical devices, and in particular to a kind of LED/light source that illumination is dyed for Medical endoscope spectrum.
The invention further relates to a kind of LED illumination method that illumination is dyed for Medical endoscope spectrum.
Background technology
The conventional endoscope light source drive devices such as cold light source point halogen, xenon lamp, LED, wherein halogen light source cost into
This is relatively low, but is only capable of because colour rendering index is not high meeting general scope lighting demand, xenon source colour temperature and colour rendering index energy base
This meets endoscope illumination demand, but its cost highly energy-consuming is also high and short life also constrains its application on scope, at present
Although common LED lighting engineering has made significant headway, but still difficulty meets scope high-resolution high-contrast on colour rendering index
Demand.
Endoscope camera technique achieved significant progress in recent years, and image definition, contrast are obtained for very big
Lifting, under common white-light illuminating, the focus (such as raised lump and the ulcer of depression) that form and color substantially change is all
Can clearly it image.But it is difficult diagnosis for small, flat early carcinomatous change and atypical hyperplasia etc. or even causes to fail to pinpoint a disease in diagnosis.It is near
Year, external scope company largely refer to the technologies such as Endoscopy, electronics light splitting, Narrow-Band Imaging, optical biopsy, fluorescence imaging,
Substantially increase the diagnostic level of early carcinomatous change.
Research shows, it is seen that in spectrum, and the depth that photon penetrates into mucosal tissue is relevant with the wavelength of radiation source, wavelength
The shorter depth for penetrating into sticking to mould tissue is more shallow, in addition, hemoglobin is the main matter for absorbing visible ray, to blue and green light
Absorptivity is high, and feux rouges is not absorbed substantially.
There are some researches show the superficial capillary on gastrointestinal mucosal surface is high to 415nm blue light absorption rate, and subcutaneous micro-
Blood vessel is high to 540nm green glow absorptivity.
Scope is 400nm-800nm with the wavelength cover of ordinary light source, has good illumination for common imaging,
But the image contrast of mucous layer capillary and subcutaneous capilary can not be improved.And utilize Narrow-Band Imaging, electron stain to be imaged
Scope successfully solves above mentioned problem.
The band illumination imaging technique that certain Japanese company releases is to employ narrow-band interference blue green optical filter, produces center
Wavelength is 415nm, 540nm, the NBI illuminators of the blue green arrowband light wave with a width of 30nm respectively.But this system there is also
Some defects：
1st, gastrointestinal disease changes not fully related to submucosal blood vessel traveling.
The polyp for more such as having canceration to be inclined to, says, the change of their surface mucosa forms is than in mucous membrane in theory
The change of blood vessel traveling is much more obvious, and this to be NBI can not see.
2nd, hemochrome absorbs arrowband ripple and changes color.
NBI principle is to highlight color with the spectral absorption effect of hemochrome.When in stomach or colon has one
Blutpunkte often is had on some rotten to the corn, ulcer (this is enterogastric diseases extremely common lesion), erosion/ulcer surface, these points general
Shown on NBI excessively obvious.This shortcoming will cover the discovery of other lesions, such as the change of anterior pituitary-adrenal cortex axis.
3rd, only after definite clear and definite lesion locations, NBI can just be opened, and otherwise will influence normal gastrointestinal endoscopy
Progress.
4th, NBI is what the narrowband wavelength based on single-mode was designed, it means that the result that NBI is checked is in oesophagus and colon
It is different.
5th, NBI Technology design is filtered with filter disc, if necessary to carry out technology upgrading, then needs upgrading hardware, spend compared with
Greatly.
6th, NBI needs the effect for coordinating zoom magnifying endoscope just to have.
