内窥镜经过长期的手术室仪器设备维修，发现内窥镜故障根据维修难易和故障大小，可分为复杂故障、中等故障和简单故障。无论何种故障都必须懂得内窥镜的工作原理，凭借丰富的维修经验技术处理。

After long-term maintenance of instruments and equipment in the operating room, it is found that endoscope faults can be divided into complex faults, medium faults and simple faults according to the difficulty and size of maintenance. No matter what kind of fault, we must understand the working principle of the endoscope and deal with it with rich maintenance experience and technology.

一、图像偏色

1、 Image color deviation

在白平衡后和排除其他配套设备的影响下都无法还原景物的颜色时，我们认为可能是由导线老化信号传递缺陷引起的，也可能是摄像头电路元件老化变质，又或者是由摄像头CCD老化引起。此时我们只需更换内窥镜显示器相应的配件则可。

When the color of the scene cannot be restored after the white balance and excluding the influence of other supporting equipment, we think it may be caused by the aging of the wire, the defect of signal transmission, the aging and deterioration of the camera circuit elements, or the aging of the camera CCD. At this time, we only need to replace the corresponding accessories of the endoscope display.

二、图像有干扰

2、 Image interference

一般是因为用电刀等高频设备的时候对线路产生干扰，这时候我们要检查的是摄像头与连接中的屏蔽线是否有接通。还有一种情况就是没有使用高频设备的时候也会出现干扰条纹，这时候是连接线信号线由于长期使用，屏蔽层磨损。

Generally, it is because the use of high-frequency equipment such as electric knife interferes with the line. At this time, we need to check whether the camera is connected to the shielding wire in connection. There is also a case that interference stripes will appear when high-frequency equipment is not used. At this time, the shielding layer of the connecting line signal line is worn due to long-term use.

需要看是摄像头的连接处出问题还是整条线体老化，前者需要重新焊接，而后者则需要更换连接导线了。目前更换原装进口的3m长的连接导线价格在10000RMB左右。所以内窥镜显示器使用过程中尽量避免导线在地上被仪器车或手术车碾过。

We need to see whether the connection of the camera is faulty or the whole line is aging. The former needs to be re welded, while the latter needs to replace the connecting wire. At present, the price of replacing the original imported 3M long connecting wire is about 10000RMB. Therefore, during the use of the endoscope display, try to avoid the wire being run over by the instrument car or surgical car on the ground.

内窥镜设备维修厂家提醒您，内窥镜在使用后的保养程度，会直接影响硬镜的寿命。只有认真地做好日常保养，才能够延长硬镜的使用寿命、减少硬镜的磨损和老化、降低维修成本、减少不必要的停机时间。

The endoscope equipment maintenance manufacturer reminds you that the maintenance degree of the endoscope after use will directly affect the service life of the hard mirror. Only by doing a good job in daily maintenance can we prolong the service life of hard mirrors, reduce the wear and aging of hard mirrors, reduce maintenance costs and reduce unnecessary downtime.
