硬管內窺鏡是目前為止醫務人員觀察人體內部病變組織方便、直接、有效的醫療器械，具有圖像清晰度高、色彩逼真等優點，而且容易操作。為了讓大家更好的認識他，下面內窺鏡設備維修人員來講講硬管內窺鏡設備的結構。

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.

要想正確使用硬管內窺鏡就應該了解它的結構。目前世界上各個硬管內窺鏡生產廠的產品雖然光路不同、外觀不同，但是其基本結構都是一致的：由工作鏡管部分、結構部分、眼罩部分、光纜接口部分組成。

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.

結構主體部分、眼罩部分、光纜接口部分除了受到劇烈的磕碰一般不易受損。容易損壞的部分就是工作鏡管部分。以φ4mm硬管內窺鏡為例：工作鏡管主要由四個部分組成：外鏡管、內鏡管、光學鏡片、光導纖維。

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.

光學鏡片放在內鏡管組成光學系統，光導纖維放在內、外鏡管之間負責照明。外鏡管是0.1mm厚φ4mm不銹鋼管，受到磕碰或擠壓都會變形。

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.

光學鏡片大部分是φ2.8mm長25mm左右的玻璃柱，受到輕微的磕碰和擠壓就會開裂、崩邊或者光軸偏移，我們常見的內窺鏡視野模糊、邊緣發黑多是此類原因。

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.

光導纖維是由很細的光學玻璃制成，一支φ4mm窺鏡要裝1500根以上，在外鏡管內受到外力回造成斷絲，影響光照度。

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.

硬管內窺鏡各機構的連接大都是用環氧樹脂膠粘接，膠的質量和封裝技術也影響窺鏡的使用壽命。

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.

硬管內窺鏡雖然嬌貴，但是只要能夠正確的使用和維護，就不會損壞，所以維護保養要定期進行，更多相關事項就來我們網站http://www.dcgr.cn進行咨詢！
