Abstract
The utility model discloses a kind of lens device, for medical electronic endoscope, comprise lens board, be arranged on the photoelectric sensor of central authorities on lens board and be set up in parallel the lamp at the LED at lens board edge, before photoelectric sensor, install and be placed with camera lens, the aspect ratio of camera lens LED lamp height arranged side by side is slightly low, the angle of visual field of camera lens is 60 degree, its field range and LED light irradiation light source are overlapping at far-end, before camera lens, be also provided with eyeglass, field of view inside in the middle of eyeglass is provided with a circular hole, in circular hole, be inlaid with a sapphire plated film lens, sapphire plated film lens edge is bonded on described eyeglass by lighttight fluid sealant, between eyeglass and camera lens, be provided with brake sack.The utility model has the advantages that: this device structure is simple, adopt double sleeve type eyeglass and brake sack, can block reflected light and the refracted light of LED lamp source at eyeglass, reduced the interference of light, also improved light permeable rate, make the image of collection more clear.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, especially a kind of lens device for medical electronic endoscope.
Background technology
At present, the handle front end of medical electronic endoscope is a whole erose PMMA eyeglass, after eyeglass, is lens board, has photoelectric sensor on lens board, installs and has placed camera lens before photoelectric sensor, and its aspect ratio LED lamp height arranged side by side is slightly low.The angle of visual field of camera lens is 60 degree, and its field range and LED radiation source are overlapping at far-end.First, when LED light source outgoing consult accompanying drawing 1, there are the following problems for prior art:, its irradiate light is to lens surface, now there is directly reflection, image that camera lens obtains is caused to interference, present slight vaporific effect, the definition of actual inspection is had to impact.Secondly, at light, pass in the process of eyeglass, the outer surface of eyeglass has also played mirror simultaneously, produces refraction and reflection for the second time, and the image equally camera lens being obtained causes interference, present relative first slighter vaporific effect, the definition of actual inspection is had to impact.
Utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of lens device that blocks reflected light and refracted light, the reduction interference of light is provided.
For realizing above object, this utility model has been taked following technical scheme: a kind of lens device, for medical electronic endoscope, comprise lens board, be arranged on the photoelectric sensor of central authorities on lens board and be set up in parallel the lamp at the LED at lens board edge, before photoelectric sensor, install and be placed with camera lens, the aspect ratio of camera lens LED lamp height arranged side by side is slightly low, the angle of visual field of camera lens is 60 degree, its field range and LED light irradiation light source are overlapping at far-end, before camera lens, be also provided with eyeglass, field of view inside in the middle of eyeglass is provided with a circular hole, in circular hole, be inlaid with a sapphire plated film lens, sapphire plated film lens edge is bonded on described eyeglass by lighttight fluid sealant, between eyeglass and camera lens, be provided with brake sack.
Sapphire plated film lens and eyeglass form double sleeve type eyeglass, can block refracted light and reflected light for the second time, have reduced the interference of light, have also increased light permeable rate, make the image that gathers more clear; Bonding with lighttight fluid sealant between double sleeve type eyeglass, the leakage that can shut out the light; The setting of brake sack, can stop the reflected light of camera lens to LED lamp source, has reduced the interference of light that reflection causes.
Compared with prior art, tool has the following advantages this utility model: this device structure is simple, adopts double sleeve type eyeglass and brake sack, can block reflected light and the refracted light of LED lamp source at eyeglass, reduced the interference of light, also improved light permeable rate, made the image of collection more clear.
Accompanying drawing explanation

Reference numeral implication in figure: 1, lens board, 2, photoelectric sensor, 3, LED lamp, 4, camera lens, 5, eyeglass, 6, sapphire plated film lens, 7, outlet pipe brake sack, 8, fluid sealant.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, content of the present utility model is described in further details.
Embodiment
Consult Fig. 1 to Fig. 3, solid line with arrow is field range, dotted line with arrow is LED lamp source scope, a kind of lens device, for medical electronic endoscope, comprise lens board 1, be arranged on the photoelectric sensor 2 of central authorities on lens board 1 and be set up in parallel the LED lamp 3 at lens board 1 edge, in the front installation of photoelectric sensor 2, be placed with camera lens 4, the aspect ratio of camera lens 4 LED lamp 3 arranged side by side is highly slightly low, the angle of visual field of camera lens 4 is 60 degree, its field range and LED lamp 3 radiation sources are overlapping at far-end, before camera lens 4, be also provided with eyeglass 5, field of view inside in the middle of eyeglass 5 is provided with a circular hole, in circular hole, be inlaid with a sapphire plated film lens 6, sapphire plated film lens 6 edges are bonded on eyeglass 5 by lighttight fluid sealant 8, between eyeglass 5 and camera lens 4, be provided with brake sack 7.
Sapphire plated film lens 6 forms double sleeve type eyeglasses with eyeglass 5, can block refracted light and reflected light for the second time, has reduced the interference of light, has also increased light permeable rate, makes the image that gathers more clear; Bonding with lighttight fluid sealant 8 between double sleeve type eyeglass, the leakage that can shut out the light; The setting of brake sack 7, can stop the reflected light of camera lens to LED lamp 3 light sources, has reduced the interference of light that reflection causes.
Above-listed detailed description is for the illustrating of this utility model possible embodiments, and this embodiment is not in order to limit the scope of the claims of the present utility model, does not allly depart from the equivalence that this utility model does and implements or change, all should be contained in the scope of the claims of this case.
