Description
Technical field
The utility model relates to a kind of endoscope illuminators, and in particular to a kind of Multipurpose endoscope light source.
Background technique
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 with high brightness, the service life is long, calorific value is 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 issue 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 tissue is distinguished

Transmission structure is converged by lens, and plane mirror realizes that optical 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, structure is complicated, occupies biggish space, and light transmissioning efficiency can also reduce.
The switching class light source of two kinds of different wave lengths, be in prior art controlled by drive control part 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, higher cost,
More unfortunately, each light source is only capable of providing fixed or specific narrow-band spectrum and identifies to 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 also can be used；But for the lesion of some specific organizations (in follow-up clinical test
Can constantly discover), 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 again optical filter 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.
