內(nèi)窺鏡經(jīng)人體的天然孔道或經(jīng)小切口進(jìn)入人體內(nèi),通過CCD采集并逐級(jí)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(shù)治療。按其發(fā)展及成像構(gòu)造分類:可大體分為3大類:硬管式內(nèi)窺鏡、纖維內(nèi)窺鏡和電子內(nèi)窺鏡。
內(nèi)窺鏡設(shè)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(nèi)窺鏡
Hard tube endoscope
硬管式內(nèi)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(tǒng)、目鏡組成傳導(dǎo)圖像。照明部分采用冷光源用光導(dǎo)纖維穿入境內(nèi)的方法。工作通道作用為送氣、送水、通活檢鉗。硬性內(nèi)窺鏡產(chǎn)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(chǎng)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(nèi)窺鏡
Fiber endoscope
用纖維光束傳像和導(dǎo)光或用CCD傳導(dǎo)圖像的內(nèi)窺鏡成為纖維內(nèi)窺鏡。由于它具有良好的柔軟性和方便的操作性能,在醫(yī)學(xué)上得到了廣泛的應(yīng)用。目前產(chǎn)品有胃鏡、十二指腸鏡、結(jié)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(nèi)窺鏡一般由目鏡、手輪(軟性或半硬性)、鉗道口、導(dǎo)光束接口、導(dǎo)像束、導(dǎo)光束組成,有些產(chǎn)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(nèi)窺鏡
Electronic endoscope
電子內(nèi)窺鏡系統(tǒng)一般包括內(nèi)窺鏡、圖像處理裝置、內(nèi)窺鏡冷光源、顯示器和其他輔助設(shè)備。內(nèi)窺鏡冷光源發(fā)出的光通過光導(dǎo)接頭導(dǎo)入內(nèi)窺鏡內(nèi),經(jīng)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(hào)轉(zhuǎn)換為電信號(hào),通過電纜線傳輸?shù)綀D像處理裝置,圖像處理裝置接收來自內(nèi)窺鏡的圖像信號(hào)并轉(zhuǎn)換成影像信號(hào),終呈現(xiàn)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(nèi)窺鏡在使用中有可能接觸破損黏膜,特別是用于手術(shù)的內(nèi)窺鏡,一旦被微生物污染,具有高感染風(fēng)險(xiǎn),用戶在每次使用前后應(yīng)清潔并對(duì)其進(jìn)行消毒滅菌。更多相關(guān)事項(xiàng)就來我們網(wǎng)站

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://yuxiaous.cn Ask and understand!
