Endoscope with a clever integrated image processing device and leading international standards of endoscope technology and favored by the medical market, but in practical use is easy to damage due to improper operation or improper maintenance. So what happens when there's no signal on the endoscope output?

　　内窥镜清洗消毒后没有擦干镜子导光部，将湿的导光杆部插到光源里，长期以来导致电子接触点生锈氧化，电子信号不能传输，故障表现为图像反白。医护人员使用和操作不当导致电子器件松脱或防水盖漏水，电子接点跟主机接触不良，电子信号不能传输，故障表现为图像异常、偏色、干扰等。调光电缆没有接好，主机与光源之间连接不当，电子信号不能传输，故障表现为图像变黑白。

　　The light guide part of the mirror is not dried after cleaning and disinfection of the endoscope, and the wet light guide rod part is inserted into the light source, which leads to the rusting and oxidation of the electronic contact point for a long time, and the electronic signal cannot be transmitted, and the fault is reflected in the image whitening. Improper use and operation of medical personnel lead to loose electronic devices or waterproof cover leakage, poor contact between electronic contacts and the host, electronic signals cannot be transmitted, and the fault is abnormal image, color deviation, interference, etc. The dimming cable is not properly connected, the connection between the host and the light source is improper, the electronic signal cannot be transmitted, and the fault is shown as the image becomes black and white.

　　怎样避免内窥镜光亮调节的问题？将内镜插入光源前，必须确认导光杆顶部干燥;保持光源插座干燥，触片没氧化;避免内镜碰撞;使用内镜前应检查调光功能是否正常。

　　How to avoid the problem of endoscope brightness adjustment? Before inserting the endoscope into the light source, ensure that the top of the light guide rod is dry; Keep the light source socket dry, contact piece is not oxidized; Avoid endoscopic collision; Before using endoscope, check whether the dimming function is normal.

　　从理论上说，各种设备和部件都有或许发生质量问题。值得指出的是，某些设备从全体上讲质量上或许没有呈现不能运用的问题，但从某些技术目标上却达不到产品阐明书上给出的目标。因而必须对所选的产品进行必要的抽样检测。如确属产品质量问题，有效的办法是更换该产品，而不该自行拆开修理。

　　Theoretically speaking, all kinds of equipment and components may have quality problems. It is worth pointing out that some equipment from the overall quality may not present the problem of not being able to use, but from some technical objectives are not up to the objectives given in the product description book. Therefore, necessary sampling tests must be carried out on the selected products. If the quality of the product is a problem, the effective way is to replace the product, rather than to dismantle the repair.

　　总之，内窥镜的使用一定要正确，平常使用中也要注重维护和保养，不然任何设备使用时间长了都会出问题的。更多相关信息您可以来网站http://www.jiangrenyiliao.cn咨询客服。

　　Anyhow, the use of endoscope must be correct, also should notice to maintain and maintain in ordinary use, otherwise any equipment uses time to grow can give a problem. More information you can to website http://www.jiangrenyiliao.cn consulting service.
