硬管内窥镜是目前为止医务人员观察人体内部病变组织方便、直接、有效的医疗器械，具有图像清晰度高、色彩逼真等优点，而且容易操作。为了让大家更好的认识他，下面内窥镜设备维修人员来讲讲硬管内窥镜设备的结构。

Hard tube endoscope is a convenient, direct and effective medical instrument for medical personnel to observe pathological tissues in human body so far. It has the advantages of high image definition, vivid color, etc., and is easy to operate. In order to let everyone know him better, the endoscope equipment maintenance personnel will talk about the structure of the hard tube endoscope equipment.

要想正确使用硬管内窥镜就应该了解它的结构。目前世界上各个硬管内窥镜生产厂的产品虽然光路不同、外观不同，但是其基本结构都是一致的：由工作镜管部分、结构部分、眼罩部分、光缆接口部分组成。

If you want to use hard tube endoscope correctly, you should understand its structure. At present, although the products of various hard tube endoscope manufacturers in the world have different optical paths and appearances, their basic structures are the same: they are composed of the working lens tube part, the structure part, the eye mask part, and the optical cable interface part.

结构主体部分、眼罩部分、光缆接口部分除了受到剧烈的磕碰一般不易受损。容易损坏的部分就是工作镜管部分。以φ4mm硬管内窥镜为例：工作镜管主要由四个部分组成：外镜管、内镜管、光学镜片、光导纤维。

The main part of the structure, the eye shield part and the optical cable interface part are generally not easy to be damaged except for severe collision. The easily damaged part is the working mirror tube. with φ Take 4mm hard tube endoscope as an example: the working lens tube is mainly composed of four parts: external lens tube, endoscope tube, optical lens and optical fiber.

光学镜片放在内镜管组成光学系统，光导纤维放在内、外镜管之间负责照明。外镜管是0.1mm厚φ4mm不锈钢管，受到磕碰或挤压都会变形。

The optical lens is placed on the endoscope tube to form an optical system, and the optical fiber is placed between the inner and outer tubes for lighting. The external mirror tube is 0.1mm thick φ 4mm stainless steel pipe will be deformed if it is bumped or squeezed.

光学镜片大部分是φ2.8mm长25mm左右的玻璃柱，受到轻微的磕碰和挤压就会开裂、崩边或者光轴偏移，我们常见的内窥镜视野模糊、边缘发黑多是此类原因。

Most optical lenses are φ The 2.8mm long and 25mm long glass column will crack, collapse or optical axis shift when slightly bumped and squeezed. The common reasons for this are blurred vision and blackened edges of endoscopes.

光导纤维是由很细的光学玻璃制成，一支φ4mm窥镜要装1500根以上，在外镜管内受到外力回造成断丝，影响光照度。

Optical fiber is made of very thin optical glass φ More than 1500 pieces of 4mm camera shall be installed, and the wire is broken due to external force in the external lens tube, which affects the light intensity.

硬管内窥镜各机构的连接大都是用环氧树脂胶粘接，胶的质量和封装技术也影响窥镜的使用寿命。

The connection of each mechanism of the rigid tube endoscope is mostly made with epoxy resin adhesive. The quality of the adhesive and the packaging technology also affect the service life of the endoscope.

硬管内窥镜虽然娇贵，但是只要能够正确的使用和维护，就不会损坏，所以维护保养要定期进行，更多相关事项就来我们网站http://www.jiangrenyiliao.cn进行咨询！
