How to repair the common troubles of endoscope display? After a long-term operation room instrument and equipment maintenance, it is found that the fault can be divided into complex fault, medium fault and simple fault according to the maintenance difficulty and fault size. No matter what kind of fault, we must understand the working principle of the instrument and deal with it with rich maintenance experience.

内窥镜显示器

Endoscopic display

一、图像偏色

1、 Image skew

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 the influence of other supporting equipment is excluded, we think it may be caused by the aging signal transmission defect of the wire, the aging deterioration of the camera circuit components, 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

Two. There is interference in the image

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。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。

Generally, it is because the 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 shield wire in the connection. Another situation is that interference fringes will appear when the 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. It depends on whether the connection of the camera is faulty or the whole line is aging. The former needs to be re welded, and the latter needs to replace the connecting wire. At present, the price for replacing the 3M long connecting wire imported from the original factory is about 10000 RMB. Therefore, during the use of the endoscopic display, try to avoid the wires being run over by the instrument car or the surgical vehicle on the ground.
