Abstract
The utility model provides a one-path image-turning sharing stereoscopic endoscope which comprises an image-turning system and a channel system. The image-turning system sequentially comprises image-turning lens sets, a split image-turning lens front portion, a polarization analyzer, a beam splitter prism polarization analyzer and split image-turning lens back portions in the axial direction. The channel system sequentially comprises objective lens front ends, a beam splitter prism polarizer, a polarizer and an objective lens back ends. The one-path image-turning sharing stereoscopic endoscope has the advantages that the polarization analyzers are arranged in the image-turning system, the resolution capability and the image plane brightness can be improved by utilizing the light-passing aperture of the endoscope most effectively, and manufacturing of the stereoscopic endoscope with a smaller external diameter is facilitated; meanwhile, direct imaging can be achieved through light paths of the split image-turning lens back portions, and complex structures like eye lenses are eliminated.
Description
Technical field
This utility model belongs to stereo endoscope field, especially relates to a kind of single channel image rotation and shares stereo endoscope.
Background technology
The observation of stereo-picture is the object in sight line to be observed by two eyes left eyes and right eye simultaneously.By the image of left eye and the viewed diverse location of right eye, more just there is three-dimensional perception effect through brain.Due to the raising day by day that medicine and hygiene fields requires at present, the stereo endoscope that can help doctor to judge focus locus has obtained increasing application.
At present stereo endoscope on the market mainly contains two kinds of monocular single channel and the binocular dual pathwayss.Monocular single channel body formula sight glass 3D effect mainly becomes 3D effect by follow-up electron process, and stereoeffect is bad, by market, is eliminated gradually at present.Although binocular bilateral body formula sight glass road has solved problem of dtmf distortion DTMF at imaging effect, owing to being the dual pathways, front end insertion portion external diameter is generally larger, does not meet the characteristics and evolution trend of Minimally Invasive Surgery.It is effective that a kind of three-dimensional imaging is badly in need of in therefore current stereo endoscope field, and front end insertion portion external diameter can meet the stereo endoscope of Minimally Invasive Surgery standard simultaneously.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of single channel image rotation and shares stereo endoscope, is especially applicable to solving on current medical diagnosis the little demand of the effective while front end external diameter of three-dimensional endoscopic imaging.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
Provide a kind of single channel image rotation to share stereo endoscope, comprise relay system and channel system, relay system is followed successively by image transferring lens group vertically, quilt is split image transferring lens front portion, analyzer, Amici prism analyzer and split image transferring lens rear portion; Channel system is object lens front end, the Amici prism polarizer, the polarizer and object lens rear end vertically successively.
Wherein, described image transferring lens group is the battery of lens that multi-disc lens set uniformly-spaced arranges.
The beneficial effects of the utility model are, analyzer is arranged in relay system, can utilize most effectively endoscope's clear aperture, improve resolution capability and image planes brightness, are beneficial to and manufacture the thinner stereo endoscope of external diameter.Meanwhile, the light path that splits image transferring lens rear portion by quilt can direct imaging, has removed the labyrinths such as eyepiece from.
Accompanying drawing explanation
Fig. 1 is that a kind of single channel image rotation of this utility model shares stereo endoscope schematic diagram
Fig. 2 is this utility model channel system part enlarged drawing
In figure:
1, object lens front end 2, the Amici prism polarizer 3, the polarizer
4, object lens rear end 5, image transferring lens group 6, quilt are split image transferring lens front portion
7, analyzer 8, Amici prism analyzer 9, quilt are split image transferring lens rear portion
The specific embodiment
As shown in Fig. 1 Fig. 2, a kind of single channel image rotation of this utility model shares stereo endoscope and comprises relay system and channel system, and relay system is followed successively by image transferring lens group vertically, quilt is split image transferring lens front portion, analyzer, Amici prism analyzer and split image transferring lens rear portion; Channel system is object lens front end, the Amici prism polarizer, the polarizer and object lens rear end vertically successively.
The work process of this example: by the two-way light path of object lens front end symmetrical in channel system, after successively by the Amici prism polarizer and the polarizer, pool a road light path, by object lens rear end, continue to propagate, after image transferring lens group, arrive relay system, by quilt, split image transferring lens anterior, analyzer, after Amici prism analyzer, Yi road light path is divided into again two-way light path before, then respectively through being split image transferring lens rear portion, due to analyzer is arranged in relay system, can utilize most effectively endoscope's clear aperture, improve resolution capability and image planes brightness, be beneficial to and manufacture the thinner stereo endoscope of external diameter.Meanwhile, the light path that splits image transferring lens rear portion by quilt can direct imaging, has removed the labyrinths such as eyepiece from.
Above an embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variations of doing according to this utility model application range and improvement etc., within all should still belonging to patent covering scope of the present utility model.
Claims (2)
1. single channel image rotation shares a stereo endoscope, comprises relay system and channel system, it is characterized in that: relay system is followed successively by image transferring lens group vertically, quilt is split image transferring lens front portion, analyzer, Amici prism analyzer and split image transferring lens rear portion; Channel system is object lens front end, the Amici prism polarizer, the polarizer and object lens rear end vertically successively.
