我们知道纤维内窥镜的成像，是通过成像束、物镜直接接触被检部位，在冷光源、导光束的照射下，将被检部位经物镜、像束反射到目镜上进行观察的，同样“彩带彩斑”的形成也是通过这一光学路径的。那么在什么条件下才能形成“彩带彩斑”呢？下面内窥镜设备维修人员为您分析：

We know that the imaging of a fiber endoscope is achieved by directly contacting the inspected area with an imaging beam or objective, and under the illumination of a cold light source or guiding beam, the inspected area is reflected onto the objective lens or image beam for observation. Similarly, the formation of "ribbon spots" is also through this optical path. So under what conditions can "ribbons and spots" be formed? Below, the maintenance personnel of the endoscope equipment will analyze for you:

（1）当蛇形管变曲部套皮破裂造成漏水，大量的水储留在镜内；

(1) When the curved part of the serpentine tube ruptures, causing water leakage, a large amount of water is stored in the mirror;

（2）当水气按钮上的“O”形圈老化损坏，引起手柄处漏水，水从盖板缝隙流入镜内；

(2) When the "O" ring on the water vapor button is aged and damaged, it causes water leakage at the handle, and water flows into the mirror through the gap of the cover plate;

（3）当蛇形管观察窗玻璃破裂，水进入镜内；

(3) When the observation window glass of the serpentine tube breaks, water enters the mirror;

（4）当水气管断裂水直接进入镜内。一旦水进入镜内时间过长，就会使物镜和光导纤维的连接处出现脱胶，从而水就会慢慢地渗入到物镜内，当冷光源的光照射到物镜内的水滴时，就会产生反射与折射现象，终形成了“彩带彩斑”。水渗入物镜的多少就决定了“彩带彩斑”的大小，水滴越大，“彩带彩斑”就越大越重，水滴越小“彩带彩斑”就越小越淡。

(4) When the water pipe breaks, water directly enters the mirror. Once the water enters the lens for a long time, the connection between the objective lens and the Optical fiber will be degummed, so that the water will slowly penetrate into the objective lens. When the light from the cold light source shines on the water drops in the objective lens, the reflection and refraction will occur, eventually forming "ribbons and spots". The amount of water seeping into the objective lens determines the size of the "ribbon spot". The larger the water droplet, the larger and heavier the "ribbon spot". The smaller the water droplet, the smaller and lighter the "ribbon spot".

彩带的预防

Prevention of ribbons

1.经常性的检查纤维内镜的端部，及弯曲部套皮磨损情况，发现破损或漏水，应立即停止使用。

1. Regularly check the end of the fiber endoscope and the wear of the curved part of the sheath. If damage or leakage is found, immediately stop using it.

2.对于弯曲部套皮破损严重，镜内已大面积进水，应采取果断措施，将弯曲部套皮剥去排出进水，同时在100W灯泡下烘干，灯泡和弯曲部距离20充满为宜。

2. For severe damage to the sheath of the curved part, where a large area of water has entered the mirror, decisive measures should be taken to peel off the sheath of the curved part and discharge the water. At the same time, it should be dried under a 100W light bulb, and the distance between the light bulb and the curved part should be 20.

3.当发现水气按钮处漏水，应立即停止使用，待更换“O”形圈后不漏再用。

3. When water leakage is found at the water vapor button, it should be stopped immediately and not used again after replacing the "O" ring.

4.杜绝带故障操作。有时水进入镜内较少，短时间内不影响视野，但时间一长“彩带”就慢慢形成了。

4. Eliminate faulty operations. Sometimes there is less water entering the mirror and it does not affect the field of view in a short period of time, but over time, "ribbons" gradually form.

5.当发生进水故障经上述处理后，有条件的应立即修理，无条件的必须在一周内送修。

After the above treatment, if there is a water inlet fault, it should be repaired immediately if conditions permit, and if conditions permit, it must be sent for repair within one week.

实践证明，采取以上几条措施，可以避免的纤维内镜发生彩带故障，大大提高了使用寿命。更多相关内窥镜事项就来我们网站http://www.jiangrenyiliao.cn咨询了解吧！
