Abstract
The utility model relates to the flexible fujinon electronic video endoscope of a kind of optics rigid front.Special applicable industry and medical inspection visual operation system exchange to solve between the doctors and patients.The utility model comprises three mirror optical systems, 1/4CCD imaging system, conduction optical fibre illumination, built-in instrument channel etc., be characterized in CCD is made in mirror body front end, light signal is directly changed into electric signal output, the mole effect when having solved gradually Halo during optical inversion is transmitted and two cover optical system imagings effectively.Owing to adopt 1/4 inch CCD, it is thin that external diameter can reach 7mm, and front end and handle are rigidity, and the soft bend of middle connection makes camera lens rotate up and down at 180 degree, and instrument channel is built-in also can decline.Can be widely used in industry and the department of stomatology, department of eye, gynecologial examination and visual operation.Because optical design adopts three mirror systems of big visual field high-resolution to guarantee that the undistorted and 480 line vision signals of images acquired export, and is very easy to visual aftertreatment, full screen display directly monitor also can connect computing machine and carries out image processing.
Description
Technical field
The utility model relates to the medical optical electronic device, is specifically related to a kind of medical electronic endoscope, belongs to International Classification of Patents A61B1/00 " with visual or the take a picture chamber of inspection human body or the instrument of pipe, as endoscope " technical field.
Background technology
At present, endoscopic technique is quite perfect, has a lot of companies to design and produced the endoscope of many different models, is used for medical science and industry.The videoization of image adds the optical transition interface by external CCD mostly.The problem of its existence is: 1, traditional rigid endoscope optical system in the time of need turning to, generally needs to adopt the mirror of falling the power and influence.Because emergent pupil in mirror body inside, is difficult to overlap with human eye, is easy to generate vignetting.2, the Amici prism of optical transition interface makes attenuated optical signal, and two cover optical systems connect simultaneously, are easy to generate a mole effect.These are many to be cost to lose visual sharpness.Traditional endoscope video system can not meet the demands.External electron mirror technology is made in front end with CCD, though the problem of efficiently solving, price is very expensive.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of under the situation that does not increase system cost, can effectively solve the flexible photoelectron hard tube of the front end endoscope of mole effect when vignetting and two overlaps optical system imagings in the optical inversion transmission.
The purpose of this utility model is achieved through the following technical solutions.
The flexible photoelectron hard tube of a kind of front end endoscope, comprise three mirror optical systems, 1/4CCD imaging system and conduction optical fiber illuminating system composition, it is characterized in that: three mirror optical systems and the 1/4CCD imaging system that is made of three lens group is housed at the front end of endoscope, its parameter is: field angle is 62 °, effective focal length EFFL=3mm, F/#=6.6L:6mm=＞L ': 4.06.
Described camera lens can be along four direction rotation up and down.
In the described rigid endoscope system, can built-in operating theater instruments passage, be specially flexible built-in pincers road.
Its internal illumination adopts optical fiber or luminotron.
The utility model of Shi Xianing has adopted three mirror optical systems like this, has finished achromatism and the distortion that disappears, and 1/4CCD is made in front end, carries out the compensation of image acquisition self-poise and light.Vision signal transfers electric signal output to, and two optical fibre illuminations are eliminated blind spot.Bend is adjustable in 180 ° of scopes, has increased field angle, can observe the full visual field.

Fig. 2 is the vertical view of light-conductive optic fibre or luminotron.
Among the figure: 1, protective glass, 2, three lens group, 3,1/4CCD, 4, bend; 5, light-conductive optic fibre or luminotron, 6, instrument channel, 7, preceding end mirror cover, 8, transition mirror cover; 9, guiding steel wire, 10, operating portion, 11, angle sheave, 12, control line and fiber optic cables.
Embodiment
As shown in Figure 1, 2, the flexible photoelectron hard tube of front end endoscope comprises three mirror optical systems 2,1/4CCD imaging system 3 and conduction optical fiber illuminating system 5 compositions.At the front end of endoscope three mirror optical systems and the 1/4CCD imaging system 3 that is made of three lens group 2 is housed, its parameter is: field angle is 62 °, effective focal length EFFL=3mm, F/#=6.6 L:6mm=＞L ': 4.06.Sharpness reaches 180 lines.Be easy to optics processing, be convenient to assembling.Characteristics with little focal length, the big visual field, high-resolution.Bend is welded on the seal wire by one group of universal joint and rotates, and seal wire can drive about front end or rotate 180 ° up and down.Can make as required two directions and four directions to, that is: camera lens can rotate along four direction up and down, thereby can observe the full visual field.Optical system directly by the 1/4CCD imaging, directly provides visual object to duplicate picture on screen.With electric signal transitive graph picture, direct outputting video signal.
In this rigid endoscope system, can built-in operating theater instruments passage 6, also can decline.Be specially flexible built-in pincers road.Its internal illumination adopts optical fiber or luminotron 5.
This optical system is made up of three mirrors, selects two optical glass that refractive index is high for use, improves optical stability.
The utility model is widely used in industry and the department of stomatology, department of eye, gynecologial examination and visual operation.Because three mirror systems of big visual field high-resolution are adopted in optical design, it is undistorted to have guaranteed to gather image, and the output of 480 line vision signals, has greatly made things convenient for visual aftertreatment.Full screen display can directly connect monitor, also can connect computing machine and carry out image processing.
