內窺鏡經人體的天然孔道或經小切口進入人體內，通過CCD采集并逐級處理后在外部顯示器成像，多用于人體器官或組織的檢查及手術治療。按其發展及成像構造分類：可大體分為3大類：硬管式內窺鏡、纖維內窺鏡和電子內窺鏡。內窺鏡設備維修人員為您講解。

Endoscopes enter the human body through natural channels or small incisions, are collected by CCD, processed step by step, and then imaged on the external display. They are mostly used for the examination and surgical treatment of human organs or tissues. According to its development and imaging structure, it can be generally divided into three categories: rigid tube endoscope, fiber endoscope and electronic endoscope. The endoscope equipment maintenance personnel will explain to you.

硬管式內窺鏡

Hard tube endoscope

硬管式內窺鏡包括傳像、照明、工作通道三大部分。傳像部分分為物鏡、中繼系統、目鏡組成傳導圖像。照明部分采用冷光源用光導纖維穿入境內的方法。工作通道作用為送氣、送水、通活檢鉗。硬性內窺鏡產品有喉鏡、鼻竇鏡、膀胱鏡、子宮鏡、直腸鏡等，狼牌(WOLF)、史托斯(STORZ)硬性鏡市場做的好，還有很多品牌硬性鏡，競爭激烈。

The rigid tube endoscope includes three parts: image transmission, lighting and working channel. The image transmission part is divided into objective lens, relay system and eyepiece to form a conductive image. The lighting part adopts the method of penetrating cold light source into China with optical fiber. The function of the working channel is to supply air, water and biopsy forceps. Hard endoscopes include laryngoscope, sinusoscope, cystoscope, hysteroscope, rectoscope, etc. The market of WOLF and STORZ hard endoscopes is good, and there are many brands of hard endoscopes with fierce competition.

纖維內窺鏡

Fiber endoscope

用纖維光束傳像和導光或用CCD傳導圖像的內窺鏡成為纖維內窺鏡。由于它具有良好的柔軟性和方便的操作性能，在醫學上得到了廣泛的應用。目前產品有胃鏡、十二指腸鏡、結腸鏡、膽道鏡、小腸鏡、支氣管鏡、輸尿管鏡等。

An endoscope that transmits images and guides light with a fiber beam or transmits images with a CCD becomes a fiber endoscope. Because of its good softness and convenient operation, it has been widely used in medicine. At present, the products include gastroscope, duodenoscope, colonoscope, choledochoscope, enteroscope, bronchoscope, ureteroscope, etc.

纖維內窺鏡一般由目鏡、手輪（軟性或半硬性）、鉗道口、導光束接口、導像束、導光束組成，有些產品還包括送水（氣）孔、閉孔器等。

Fiber endoscope is generally composed of eyepiece, handwheel (soft or semi hard), clamping mouth, beam guide interface, image guide beam, and beam guide. Some products also include water (air) supply hole, hole closer, etc.

電子內窺鏡

Electronic endoscope

電子內窺鏡系統一般包括內窺鏡、圖像處理裝置、內窺鏡冷光源、顯示器和其他輔助設備。內窺鏡冷光源發出的光通過光導接頭導入內窺鏡內，經過照明光纖和照明透鏡，照射到黏膜上。頭端部的圖像傳感器（CCD或CMOS）將接收到的黏膜反射光信號轉換為電信號，通過電纜線傳輸到圖像處理裝置，圖像處理裝置接收來自內窺鏡的圖像信號并轉換成影像信號，終呈現在顯示器的屏幕上。

The electronic endoscope system generally includes the endoscope, image processing device, endoscope cold light source, display and other auxiliary equipment. The light from the cold light source of the endoscope is introduced into the endoscope through the optical guide connector, and then shines on the mucosa through the lighting fiber and the lighting lens. The image sensor (CCD or CMOS) at the head end converts the received reflected light signal of the mucous membrane into an electrical signal, which is transmitted to the image processing device through the cable. The image processing device receives the image signal from the endoscope and converts it into an image signal, which is finally displayed on the screen of the display.

內窺鏡在使用中有可能接觸破損黏膜，特別是用于手術的內窺鏡，一旦被微生物污染，具有高感染風險，用戶在每次使用前后應清潔并對其進行消毒滅菌。更多相關事項就來我們網站http://www.cnxgtzyj.cn咨詢了解吧！

Endoscopes may contact damaged mucous membranes during use, especially those used for surgery. Once they are contaminated by microorganisms, they pose a high risk of infection. Users should clean and disinfect them before and after each use. Come to our website for more information http://www.cnxgtzyj.cn Ask and understand!
