Abstract
The utility model discloses a wide probing visual field and more accurate focus judgment medical endoscope, which pertains to medical devices field. A reflector with an angle chosen from 90-120 DEG is fixed on the probing lens slope inner wall of the out case. A lighting optical fiber, a focusing liner cylinder and a lens sleeve with lenses group are provided in the out case. The utility model overcomes the shortages of the present techniques that the straight-type probing lens is narrow in the visual field, limited in angles and can not find many focuses easily. The utility model can broaden the probing visual field, improve the discover rate of focuses and adjust the angle of the reflector to adapt the examinations of different acquirements. The utility model is a medical endoscope which has a widespread application.
Description
Technical field
This utility model belongs to the medical apparatus and instruments scope, particularly visiting looking away, a kind of more accurately medical endoscope of focus diagnosis.
Background technology
Existing hard mirror class endoscope is direct light type, visits the camera lens illumination and is pea lamp, and illumination is low, field range is little, angle is limited, and a lot of focuses are not easy to find.Because of light a little less than, check that the focus image is limited in scope, therefore might cause and fail to pinpoint a disease in diagnosis or the mistaken diagnosis phenomenon takes place.
Summary of the invention
The purpose of this utility model provides a kind of medical endoscope, it is characterized in that: the termination of shell 4 is inclined-plane 3,3 inwalls are fixed a reflecting mirror 2 on the inclined-plane, sealing and fixing light transmission piece 1 on shell 4 and 3 acutangulate one side, inclined-plane is that one deck illuminated light guide fiber 8 is supported on the optical fiber lining 7 near shell 4 inwalls; Focusing lining 6 and eyeglass sleeve 5 are fixed together, and battery of lens 9 is fixed in the eyeglass sleeve 5.
The angle of described reflecting mirror can be selected 90-120 ° of scope with the angle on shell and inclined-plane.
The beneficial effects of the utility model are the field of view that enlarged endoscope, adjust the angle of reflecting mirror, can adapt to the inspection of different needs.Improve the discovery rate and the accuracy rate of focus greatly.
Description of drawings
Fig. 1 is the medical endoscope structural representation.
The specific embodiment
Figure 1 shows that the medical endoscope structural representation.The termination of its shell 4 is inclined-plane 3, and 3 inwalls are fixed a reflecting mirror 2 on the inclined-plane, as optical axis refraction, the image of object (focus) is refracted to the battery of lens imaging.Sealing and fixing one light transmission piece 1 on shell 4 and 3 acutangulate one side, inclined-plane is that one deck illuminated light guide fiber 8 is supported on the optical fiber lining 7 near shell 4 inwalls, light source is provided for the visiting head; Focusing lining 6 and eyeglass sleeve 5 have been fixed on, the lining 6 of the focusing adjustment focal length that can slidably reciprocate in shell 4.Battery of lens 9 is fixed in the eyeglass sleeve 5.Fig. 1 is the structure of the first end of endoscope's viewfinder, and all the other are identical with conventional endoscope.The angle of this reflecting mirror 2 can be selected 90-120 ° of scope with the shell 4 and the angle on inclined-plane 3.Help enlarging field of view, improve the angle of the discovery rate and the adjustment reflecting mirror of focus, can adapt to the inspection of different needs.
