经过长期的手术室仪器设备维修，发现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，我们都必须懂得仪器的工作原理，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, faults can be classified into complex faults, medium faults, and simple faults based on the difficulty and size of the maintenance. Regardless of the type of malfunction, we must understand the working principle of the instrument and rely on rich maintenance experience to handle it technically.

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 white balance and excluding the influence of other supporting equipment, we believe that it may be caused by the aging signal transmission defect of the wire, the aging and deterioration of the camera circuit components, or the aging of the camera CCD. At this point, 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。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。

Usually, it is because high-frequency equipment such as electric knives interfere with the circuit. At this time, we need to check whether the camera is connected to the shielding wire in the connection. Another situation is that interference fringes may appear when high-frequency equipment is not in use, which is due to the wear and tear of the shielding layer of the connecting signal line due to long-term use. It needs to be determined whether there is a problem with the connection of the camera or whether the entire cable is aging. The former needs to be re welded, while the latter needs to replace the connecting wires. The current price for replacing the original imported 3m long connecting wire is around 10000 RMB. So during the use of endoscopic displays, try to avoid wires being run over by instrument vehicles or surgical carts on the ground.
