Abstract
A hard-tube electronic endoscope comprising a hard-tube lens pipe, a light transmitting bundle plug, a connecting base, a signal socket and an imaging system is provided. Wherein, the imaging system is arranged inside the heard-tube lens pipe and is composed of an object lens unit, a CCD image sensor and a light transmitting cellosilk. The utility model can directly get images by utilizing the CCD image sensor and the light transmitting cellosilk as well as the imaging object lens and transfer the electric images to a vision processor through a signal transmission line and the light transmitting bundle plug; after processed by the vision processor, a monitor can show a high definition image. The utility model is simple in structure, clear in images and convenient in operation and has a price lower than common electronic endoscope.
Description
One, technical field
This utility model relates to a kind of endoscope, belongs to the medical optical electronic instrument technology field.
Two, background technology
At present, mainly there are two kinds of versions in the endoscope that uses in the medical system: a kind ofly be hard tube formula endoscope, another kind is a fujinon electronic video endoscope.Hard tube formula endoscope is made up of objective system, image rotation lenses system, eyepiece system and hard tube mirror usually.By the optical imagery of eyepiece outgoing after optical interface, CCD, rake and image processor are handled on monitor display image.Fujinon electronic video endoscope is the hose type structure, and it is made up of object lens, ccd image sensor, soft lens pipe and operating system usually, electronic image after image processor is handled on monitor display image.The major defect of these two kinds of endoscopies is: though the former is comparatively simple, picture quality is relatively poor; The latter is comparatively complicated by structure, and cost is higher.
Three, summary of the invention
In view of the problem of above-mentioned existence, the purpose of this utility model provides a kind of simple in structure, cheap, easy to use, and picture quality hard tube formula fujinon electronic video endoscope clearly.
Hard tube formula fujinon electronic video endoscope described in the utility model includes parts such as hard tube mirror pipe, light guide bundles plug, Connection Block, signal plug and imaging system, imaging system is arranged in the hard tube mirror pipe, and is made up of objective lens, ccd image sensor and optical fibers silk.It can utilize ccd image sensor and optical fibers silk and the direct pickup image of image-forming objective lens that is arranged in the hard tube mirror pipe, and with the charge pattern mirror that absorbed through signal transmssion line and light guide bundles plug, after electronic image reached vision processor and handle, can demonstrate high-definition image by monitor, thereby not only omitted necessary transfer optical system, eyepiece system and optical interface system in the present normally used hard tube formula endoscope, and its price is well below fujinon electronic video endoscope.
