Description
Technical field
The present invention relates to a kind of endoscope illuminators, and in particular to a kind of Multipurpose endoscope light source.
Background technology
Existing Medical endoscope cold light source, illumination when for minimally invasive endoscopy or operation.
The endoscope illuminator used in traditional medical industry is the light source using xenon lamp as core mostly, and such light source exists
The problems such as service life is short, calorific value is big, power consumption loss is big, and spectrum is relatively simple；With development in science and technology, LED shines first
The brightness of part is continuously improved, and has high brightness, long lifespan, calorific value low, and low advantage is lost in power consumption, and perfection is instead of traditional
Xenon source；The optical wavelength narrower bandwidth of laser, monochromaticjty is good, and brightness higher-energy is big；Suitable wavelength is selected,
Good narrow band light can be obtained without adding other filtering apparatus, the light source that can also be used as specific use uses.
Clearly institutional framework must be identified in endo-surgical；Nowadays, endoscope narrow band light is imaged
With the diagnosis of light power fluorescence as a kind of emerging technology, it is used directly to observation human viscera organ tissue and anatomical structure, it is right
Pathological tissues clearly visual effect is provided in the EARLY RECOGNITION of lesion and for particular procedure.
Light power fluorescence diagnosis be using photosensitizer specific wavelength light irradiation under can send out the characteristic of fluorescence come into
Capable diagnosis.Photosensitizer is under the irradiation of the light source of specific wavelength, and a series of photochemical reactions occur for photosensitizer and photo-biological is anti-
It answers, launches the fluorescence of specific wavelength, in endoscope fluoroscopic image acquisition system, tumour can be observed and normal structure is distinguished
It comes.In the diagnosis positioning of light power fluorescence, the excitation light source that different wave length is selected according to different photosensitizers is needed.Therefore exist
When clinical medicine is treated, it is often necessary to use the light of different wave length according to different photosensitizers；So doctor needs different
Required light source is connected on interface appropriate by the treatment period, and detailed process is：External light guide bundles are needed when cold light source works,
And light guide bundles are attached on endoscope, are transmitted on endoscope by light guide bundles by the light that cold light source is sent out, to be peeped to be interior
Mirror be inserted into human body in when illumination is provided, this be not only not easy to doctor operation, can not strict guarantee treatment continuity, extend
Treatment time, in some instances it may even be possible to therapeutic effect is influenced, if using the different medical light source of multi-wavelength is exported in an equipment not
The demand can only be met, and bring great convenience to obtain more preferably treatment effect to light power diagnosis and treatment
Fruit.
Current Medical Cold Light Source majority on the market is all the white light of single wavelength, has an a small number of parts that specific wavelengths are added
Narrow band light, but can not accomplish the light of multi-wavelength while can be sent out from a light source, reason is current cold light source light
Transmission structure is converged by lens, and plane mirror realizes that light path is turned back, once want the light of addition different wave length, it is necessary to
Change the structure of entire illumination delivery system, it is complicated, larger space is occupied, light transmissioning efficiency can also reduce.
The switching class light source of two kinds of different wave lengths, be in prior art by drive control part control the rotation of swivel plate with
Realize optical element optically focused output of the configuration on swivel plate.The apparatus structure is complicated, and positioning accuracy request is high, and cost is higher,
More unfortunately, each light source, which is only capable of providing fixed or specific narrow-band spectrum, is identified a small number of pathological tissues.
The spectral bandwidth of the LED light-emitting component of usually common narrow light is still wider, and color is not pure enough；For narrow band light at
As technology at present used in field can also use；But for the lesion of some specific organizations（In follow-up clinical experiment
It can constantly find）, this narrow band light will be not pure enough due to color, and interference light is more, causes lesion imaging identification not high；At this moment
It requires the light that bandwidth is narrower, color is purer, usually need to add optical filter again and be filtered, the narrow-band spectrum needed
Narrow band light.And the optical wavelength narrower bandwidth of laser, monochromaticjty are good, and brightness higher-energy is big；Suitable wavelength is selected,
Good narrow band light can be obtained without adding other filtering apparatus.
