在日常的维修工作中，医用内窥镜系统故障时有发生，常见故障有什么呢？下面内窥镜维修公司来讲讲图像显示故障事项。

In daily maintenance work, malfunctions often occur in the medical endoscope system. What are the common malfunctions? Below, the endoscope maintenance company will talk about image display faults.

图像显示故障主要包括图像异常显示和监视器无图像。

Image display faults mainly include abnormal image display and no image on the monitor.

（1）图像异常显示

(1) Abnormal image display

故障现象为监视器有图像输出，但图像出现水平或垂直彩色条纹干扰、彩色雪花状闪烁等，故障分析及处理如下：

The fault phenomenon is that the monitor has image output, but the image shows horizontal or vertical color stripe interference, color snowflake flickering, etc. The fault analysis and handling are as follows:

因检查高清摄像头手柄和电缆的连接点，此连接点在使用过程中反复弯曲和拉扯容易造成电缆损坏，图像会出现水平或垂直彩色条纹，方法是更换连接线。

Due to the inspection of the connection point between the high-definition camera handle and the cable, repeated bending and pulling during use can easily cause cable damage, resulting in horizontal or vertical color stripes in the image. The solution is to replace the connection line.

电缆线与主机相连的插头经过反复插拔或操作不当，容易出现老化腐蚀，造成接触不良、图像也会出此种故障，应对措施是加强规范性操作培训和定期维护保养。

The plug connecting the cable to the host is prone to aging and corrosion after repeated plugging or improper operation, resulting in poor contact and image failure. The response measures are to strengthen standardized operation training and regular maintenance.

由于手术室内的电气化设备越来越多，特别是电刀等高频高电流设备的应用，可能产生较小的信号干扰。尤其当电凝棒、电刀笔或连接线等器械出现漏电时，会出现每次用脚踏开关启动电凝或电切，显示器图像就完全变成彩色雪花状闪烁，松开脚踏停止输出后图像恢复正常。

Due to the increasing number of electrified equipment in the operating room, especially the application of high-frequency and high current equipment such as electric knives, small signal interference may occur. Especially when there is electrical leakage in devices such as electrocoagulation rods, electric knives, pens, or connecting wires, it will occur that every time the foot switch is used to start electrocoagulation or electrocoagulation, the display image will completely turn into a colorful snowflake flashing. After releasing the foot switch to stop output, the image will return to normal.

像这样的情况，需要立刻更换一套完好电刀设备，先保证手术顺利完成。同时把漏电的电凝棒、电刀笔或连接线等器械进行检测，及时修理或更换。

In situations like this, it is necessary to immediately replace a complete set of electric knife equipment to ensure the smooth completion of the surgery. At the same time, detect and promptly repair or replace the leaking electric coagulation rod, electric knife pen, or connecting wire.

（2）监视器无图像

(2) Monitor has no images

故障现象主要是监视器无图像输出，可以分为两种：一种为监视器呈黑屏状态，无图像，无内窥镜视野框；另一种为监视器有内窥镜视野框，但无图像。

The main fault phenomenon is that the monitor has no image output, which can be divided into two types: one is that the monitor is in a black screen state, with no image, and no endoscope field of view box; Another type is that the monitor has an endoscopic field of view frame but no image.

1、针对种故障现象，一般会考虑是否为监视器本身故障或信号输入故障造成。现在的监视器多为高清液晶显示器，对监视器进行检查时，需测量外置12V直流电源适配器是否正常供电，若无正常供电，及时更换适配器；若正常，重启设备，观察开机自检画面是否正常，如果自检不通过则可送代理商进行维修。

1. For the first fault phenomenon, it is generally considered whether it is caused by a malfunction of the monitor itself or a signal input fault. Most of the current monitors are high-definition LCD monitors. When checking the monitors, it is necessary to measure whether the external 12V DC power adapter is powered normally. If not, replace the adapter in time; If it is normal, restart the equipment, and observe whether the POST screen is normal. If the self-test fails, send it to a professional agent for repair.

2、针对第二种故障现象，应当优先考虑的是内窥镜镜子自身出现问题，比如各种电子软镜因为漏水，液体进入CCD，造成CDD底座腐蚀、严重时CCD损坏、无图像输出。而硬镜出现弯折变形、物镜碎裂等问题时，也会造成无图像故障。这些问题主要由于诊察和手术中以及中的不规范操作造成。

2. For the second type of fault phenomenon, priority should be given to the problems of the endoscope mirror itself, such as various electronic soft mirrors leaking water, liquid entering the CCD, causing corrosion of the CDD base, severe CCD damage, and no image output. When the hard mirror experiences bending deformation, objective lens fragmentation, and other issues, it can also cause no image failure. These problems are mainly caused by non-standard operations in diagnosis, surgical treatment, and sterilization and disinfection.

由于自身维修技术和设备等限制，出现上述故障的内窥镜大多数需要外送的维修公司，费时费钱。所以，规范操作十分必要，对操作人员要定期进行严格的培训和考核，以减少此类故障的发生。还有什么问题就来我们网站http://www.jiangrenyiliao.cn吧！

Due to limitations in maintenance technology and equipment, most endoscopes with the aforementioned malfunctions need to be sent out to a professional repair company, which is time-consuming and expensive. Therefore, it is necessary to standardize the operation, and operators should receive regular and strict training and assessment to reduce the occurrence of such faults.
