隨著科技的發(fā)展，醫(yī)用內(nèi)窺鏡已廣泛應(yīng)用于醫(yī)學(xué)領(lǐng)域，是人類窺視、體內(nèi)器官的重要工具之一。
With the development of science and technology, medical endoscope has been widely used in the field of medicine.
200多年來，內(nèi)窺鏡的結(jié)構(gòu)有了4次重大改進(jìn)，從初的硬管(1806-1932)、半曲式內(nèi)窺鏡(1932-1957)、纖維內(nèi)窺鏡(1957以后)和現(xiàn)在的電子內(nèi)窺鏡(1983年以后)。圖像質(zhì)量也經(jīng)歷了一次質(zhì)的飛躍。
Over the past 200 years, the structure of the endoscope has been improved four times, from the original hard tube (1806-1932) , the semi-curved endoscope (1932-1957) , the fiber endoscope (after 1957) and now the electronic endoscope (after 1983) . Image quality has also undergone a qualitative leap.
技術(shù)的發(fā)展改為燈泡做光源，而如今采用 LED照明，內(nèi)鏡也是彩色照片或彩色電視圖像。它的影像不再是組織和器官的普通影像，而是像顯微鏡下觀察到的顯微圖像，微小病變清楚可辨，其內(nèi)窺鏡設(shè)備維修影像質(zhì)量已達(dá)到很高水平。
The technology evolved to use light bulbs as light sources, but today LED lighting is used, and the endoscope is also a color photograph or color television image. Its image is no longer a normal image of tissues and organs, but a microscopic image as observed under a microscope. The tiny lesions are clearly discernible.
醫(yī)學(xué)內(nèi)窺鏡在臨床上的應(yīng)用日益普及，正朝著小型化、多功能、高成像方向發(fā)展。本文就醫(yī)用內(nèi)窺鏡的分類、組成、結(jié)構(gòu)、工作原理、臨床應(yīng)用及發(fā)展趨勢作一介紹。
The application of medical endoscope in clinic is becoming more and more popular, and it is developing towards miniaturization, multi-function and high imaging. This article introduces the classification, composition, structure, working principle, clinical application and development trend of medical endoscope.
內(nèi)窺鏡設(shè)備維修是一種常用的醫(yī)療器械，它由可彎曲部分、光源和透鏡組成。通過人體的天然孔道，或者通過外科小切口進(jìn)入人體。用時將內(nèi)窺鏡導(dǎo)入檢查器官，可直接窺視有關(guān)部位的變化。
Endoscope equipment maintenance is a kind of commonly used medical instrument, which consists of flexible parts, light source and Lens. Through the body’s natural channels or through small surgical incisions. When the endoscope is introduced into the organ, the changes of the relevant parts can be observed directly.
