在现时代中我们看到的不仅有硬管式内镜，更有了光学纤维(软管式)内镜和电子内镜。大大方便了术者对病人疾病的检查范围，更好的判断病理和观察病变。那纤维内窥镜（软管式）你们又知道多少呢？下面内窥镜维修公司为您讲解。

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.

纤维内窥镜系统由内窥镜镜体和冷光源两部分组成，镜体内有两条光导纤维束:一条叫光束，它是用来将冷光源产生的光线传导到被观测的物体表面，将被观测物表面照亮;

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;

另一条叫像束，它是把数万根直径在1微米以下的光导纤维按一行一行顺序排列成一束，一端对准目镜，另一端通过物镜片对准被观测物表面，医生通过目镜能够非常直观地看到脏器表面的情况,便于及时准确地诊断病情。例如，借助内窥镜医生可以观察胃内的溃疡或肿留，据此制定出的治疗方案。

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.

传导图像的纤维束构成了纤维内镜的核心部分，它由数万根极细的玻璃纤维组成，根据光学的全反射原理，所有玻璃纤维外面须再被覆一层折射率较低的膜，以保证所有内芯纤维传导的光线都能发生全反射。

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.

单根纤维的传递只能产生一个光点，要想看到图像，就须把大量的纤维集成束，要想把图像传递到另一端也成同样的图像，就须使每一根纤维在其两端所排列的位置相同，称为导像束。

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.

纤维内窥镜通常有两个玻璃纤维管，光通过其中之一进入体内，医生通过另一个管或通过一个摄像机来进行观察。1981年，内窥镜超声波技术研制成功，这种把先进的超声波技术与内窥镜结合在一起的新发展，大大增加了对病变诊断的准确性。有此手术可以用内窥镜和激光来做，内窥镜的光导纤维能输送激光束，烧灼赘生物或肿瘤，封闭出血的血管。

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.

医用内窥镜在不同的时期都促进了医学事业的不断发展。今后随着电子技术及其他科学技术的不断进步，相信其技术会有更广更深的发展。当然在使用中会有问题出现，您需求维修的话可以随时来我们网站http://www.jiangrenyiliao.cn进行咨询！

Medical endoscopes have promoted the continuous development of medicine in different periods. In the future, with the continuous progress of electronic technology and other science and technology, we believe that its technology will have a broader and deeper development.
