在日常的維修工作中，醫用內窺鏡系統故障時有發生，常見故障有什么呢？下面內窺鏡維修公司來講講圖像顯示故障事項。

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.

圖像顯示故障主要包括圖像異常顯示和監視器無圖像。

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

（1）圖像異常顯示

(1) Abnormal image display

故障現象為監視器有圖像輸出，但圖像出現水平或垂直彩色條紋干擾、彩色雪花狀閃爍等，故障分析及處理如下：

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:

因檢查高清攝像頭手柄和電纜的連接點，此連接點在使用過程中反復彎曲和拉扯容易造成電纜損壞，圖像會出現水平或垂直彩色條紋，方法是更換連接線。

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.

電纜線與主機相連的插頭經過反復插拔或操作不當，容易出現老化腐蝕，造成接觸不良、圖像也會出此種故障，應對措施是加強規范性操作培訓和定期維護保養。

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.

由于手術室內的電氣化設備越來越多，特別是電刀等高頻高電流設備的應用，可能產生較小的信號干擾。尤其當電凝棒、電刀筆或連接線等器械出現漏電時，會出現每次用腳踏開關啟動電凝或電切，顯示器圖像就完全變成彩色雪花狀閃爍，松開腳踏停止輸出后圖像恢復正常。

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.

像這樣的情況，需要立刻更換一套完好電刀設備，先保證手術順利完成。同時把漏電的電凝棒、電刀筆或連接線等器械進行檢測，及時修理或更換。

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）監視器無圖像

(2) Monitor has no images

故障現象主要是監視器無圖像輸出，可以分為兩種：一種為監視器呈黑屏狀態，無圖像，無內窺鏡視野框；另一種為監視器有內窺鏡視野框，但無圖像。

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、針對種故障現象，一般會考慮是否為監視器本身故障或信號輸入故障造成。現在的監視器多為高清液晶顯示器，對監視器進行檢查時，需測量外置12V直流電源適配器是否正常供電，若無正常供電，及時更換適配器；若正常，重啟設備，觀察開機自檢畫面是否正常，如果自檢不通過則可送代理商進行維修。

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、針對第二種故障現象，應當優先考慮的是內窺鏡鏡子自身出現問題，比如各種電子軟鏡因為漏水，液體進入CCD，造成CDD底座腐蝕、嚴重時CCD損壞、無圖像輸出。而硬鏡出現彎折變形、物鏡碎裂等問題時，也會造成無圖像故障。這些問題主要由于診察和手術中以及中的不規范操作造成。

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.

由于自身維修技術和設備等限制，出現上述故障的內窺鏡大多數需要外送的維修公司，費時費錢。所以，規范操作十分必要，對操作人員要定期進行嚴格的培訓和考核，以減少此類故障的發生。還有什么問題就來我們網站http://www.veeker.xyz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.
