内窥镜经人体的天然孔道或经小切口进入人体内，通过CCD采集并逐级处理后在外部显示器成像，多用于人体器官或组织的检查及手术治疗。按其发展及成像构造分类：可大体分为3大类：硬管式内窥镜、纤维内窥镜和电子内窥镜。内窥镜设备维修人员为您讲解。

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.

硬管式内窥镜

Hard tube endoscope

硬管式内窥镜包括传像、照明、工作通道三大部分。传像部分分为物镜、中继系统、目镜组成传导图像。照明部分采用冷光源用光导纤维穿入境内的方法。工作通道作用为送气、送水、通活检钳。硬性内窥镜产品有喉镜、鼻窦镜、膀胱镜、子宫镜、直肠镜等，狼牌(WOLF)、史托斯(STORZ)硬性镜市场做的好，还有很多品牌硬性镜，竞争激烈。

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.

纤维内窥镜

Fiber endoscope

用纤维光束传像和导光或用CCD传导图像的内窥镜成为纤维内窥镜。由于它具有良好的柔软性和方便的操作性能，在医学上得到了广泛的应用。目前产品有胃镜、十二指肠镜、结肠镜、胆道镜、小肠镜、支气管镜、输尿管镜等。

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.

纤维内窥镜一般由目镜、手轮（软性或半硬性）、钳道口、导光束接口、导像束、导光束组成，有些产品还包括送水（气）孔、闭孔器等。

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.

电子内窥镜

Electronic endoscope

电子内窥镜系统一般包括内窥镜、图像处理装置、内窥镜冷光源、显示器和其他辅助设备。内窥镜冷光源发出的光通过光导接头导入内窥镜内，经过照明光纤和照明透镜，照射到黏膜上。头端部的图像传感器（CCD或CMOS）将接收到的黏膜反射光信号转换为电信号，通过电缆线传输到图像处理装置，图像处理装置接收来自内窥镜的图像信号并转换成影像信号，终呈现在显示器的屏幕上。

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.

内窥镜在使用中有可能接触破损黏膜，特别是用于手术的内窥镜，一旦被微生物污染，具有高感染风险，用户在每次使用前后应清洁并对其进行消毒灭菌。更多相关事项就来我们网站http://www.jiangrenyiliao.cn咨询了解吧！

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.jiangrenyiliao.cn Ask and understand!
