在現(xiàn)時代中我們看到的不僅有硬管式內(nèi)鏡,更有了光學(xué)纖維(軟管式)內(nèi)鏡和電子內(nèi)鏡。大大方便了術(shù)者對病人疾病的檢查范圍,更好的判斷病理和觀察病變。那纖維內(nèi)窺鏡(軟管式)你們又知道多少呢?下面
內(nèi)窺鏡維修公司為您講解。
In the present era, we see not only hard tube endoscopes, but also optical fiber (hose) endoscopes and electronic endoscopes. It is greatly convenient for the operator to check the scope of the patient's disease, and better judge the pathology and observe the pathological changes. How much do you know about fiber endoscope (hose type)? The endoscope maintenance company will explain it to you.
纖維內(nèi)窺鏡系統(tǒng)由內(nèi)窺鏡鏡體和冷光源兩部分組成,鏡體內(nèi)有兩條光導(dǎo)纖維束:一條叫光束,它是用來將冷光源產(chǎn)生的光線傳導(dǎo)到被觀測的物體表面,將被觀測物表面照亮;
The fiber endoscope system is composed of the endoscope body and the cold light source. There are two optical fiber bundles in the endoscope body: one is called light beam, which is used to transmit the light generated by the cold light source to the surface of the object to be observed and illuminate the surface of the object to be observed;
另一條叫像束,它是把數(shù)萬根直徑在1微米以下的光導(dǎo)纖維按一行一行順序排列成一束,一端對準(zhǔn)目鏡,另一端通過物鏡片對準(zhǔn)被觀測物表面,醫(yī)生通過目鏡能夠非常直觀地看到臟器表面的情況,便于及時準(zhǔn)確地診斷病情。例如,借助內(nèi)窺鏡醫(yī)生可以觀察胃內(nèi)的潰瘍或腫留,據(jù)此制定出的治療方案。
The other one is called image beam, which arranges tens of thousands of optical fibers with a diameter of less than 1 μ m into a bunch in line by line. One end is aligned with the eyepiece, and the other end is aligned with the object surface through the object lens. The doctor can see the condition of the organ surface intuitively through the eyepiece, which is convenient for timely and accurate diagnosis of the disease. For example, with the help of endoscope, the doctor can observe the ulcer or swelling in the stomach, and formulate a treatment plan accordingly.
傳導(dǎo)圖像的纖維束構(gòu)成了纖維內(nèi)鏡的核心部分,它由數(shù)萬根極細的玻璃纖維組成,根據(jù)光學(xué)的全反射原理,所有玻璃纖維外面須再被覆一層折射率較低的膜,以保證所有內(nèi)芯纖維傳導(dǎo)的光線都能發(fā)生全反射。
The fiber bundle of image transmission constitutes the core of fiber endoscope, which is composed of tens of thousands of extremely thin glass fibers. According to the principle of total reflection of optics, all glass fibers must be covered with a layer of film with low refractive index to ensure that the light transmitted by all inner core fibers can be fully reflected.
單根纖維的傳遞只能產(chǎn)生一個光點,要想看到圖像,就須把大量的纖維集成束,要想把圖像傳遞到另一端也成同樣的圖像,就須使每一根纖維在其兩端所排列的位置相同,稱為導(dǎo)像束。
The transmission of a single fiber can only produce one light point. In order to see the image, a large number of fibers must be integrated into a bundle. In order to transfer the image to the other end as the same image, each fiber must be arranged in the same position at its two ends, which is called the image guide bundle.
纖維內(nèi)窺鏡通常有兩個玻璃纖維管,光通過其中之一進入體內(nèi),醫(yī)生通過另一個管或通過一個攝像機來進行觀察。1981年,內(nèi)窺鏡超聲波技術(shù)研制成功,這種把先進的超聲波技術(shù)與內(nèi)窺鏡結(jié)合在一起的新發(fā)展,大大增加了對病變診斷的準(zhǔn)確性。有此手術(shù)可以用內(nèi)窺鏡和激光來做,內(nèi)窺鏡的光導(dǎo)纖維能輸送激光束,燒灼贅生物或腫瘤,封閉出血的血管。
Fiber endoscope usually has two glass fiber tubes. Light enters the body through one of them. The doctor observes through the other tube or through a camera. In 1981, endoscopic ultrasound technology was successfully developed. This new development, which combines advanced ultrasound technology with endoscopy, has greatly increased the accuracy of disease diagnosis. Endoscope and laser can be used for this operation. The optical fiber of endoscope can deliver laser beam, burn vegetation or tumor, and seal bleeding blood vessels.
醫(yī)用內(nèi)窺鏡在不同的時期都促進了醫(yī)學(xué)事業(yè)的不斷發(fā)展。今后隨著電子技術(shù)及其他科學(xué)技術(shù)的不斷進步,相信其技術(shù)會有更廣更深的發(fā)展。當(dāng)然在使用中會有問題出現(xiàn),您需求維修的話可以隨時來我們網(wǎng)站
