在日常的維修工作中，醫(yī)用內(nèi)窺鏡系統(tǒng)故障時(shí)有發(fā)生，常見故障有什么呢？下面內(nèi)窺鏡維修公司來講講圖像顯示故障事項(xiàng)。

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(jiān)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(xiàn)象為監(jiān)視器有圖像輸出，但圖像出現(xiàn)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(diǎn)，此連接點(diǎn)在使用過程中反復(fù)彎曲和拉扯容易造成電纜損壞，圖像會(huì)出現(xiàn)水平或垂直彩色條紋，解決方法是更換連接線。

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(jī)相連的插頭經(jīng)過反復(fù)插拔或操作不當(dāng)，容易出現(xiàn)老化腐蝕，造成接觸不良、圖像也會(huì)出此種故障，應(yīng)對(duì)措施是加強(qiáng)規(guī)范性操作培訓(xùn)和定期維護(hù)保養(yǎng)。

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(shù)室內(nèi)的電氣化設(shè)備越來越多，特別是電刀等高頻高電流設(shè)備的應(yīng)用，可能產(chǎn)生較小的信號(hào)干擾。尤其當(dāng)電凝棒、電刀筆或連接線等器械出現(xiàn)漏電時(shí)，會(huì)出現(xiàn)每次用腳踏開關(guān)啟動(dòng)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(fù)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(shè)備，先保證手術(shù)順利完成。同時(shí)把漏電的電凝棒、電刀筆或連接線等器械進(jìn)行檢測(cè)，及時(shí)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(jiān)視器無圖像

(2) Monitor has no images

故障現(xiàn)象主要是監(jiān)視器無圖像輸出，可以分為兩種：一種為監(jiān)視器呈黑屏狀態(tài)，無圖像，無內(nèi)窺鏡視野框；另一種為監(jiān)視器有內(nèi)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(duì)第一種故障現(xiàn)象，一般會(huì)考慮是否為監(jiān)視器本身故障或信號(hào)輸入故障造成?，F(xiàn)在的監(jiān)視器多為高清液晶顯示器，對(duì)監(jiān)視器進(jìn)行檢查時(shí)，需測(cè)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(shí)更換適配器；若正常，重啟設(shè)備，觀察開機(jī)自檢畫面是否正常，如果自檢不通過則可送至專業(yè)代理商進(jìn)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(duì)第二種故障現(xiàn)象，應(yīng)當(dāng)優(yōu)先考慮的是內(nèi)窺鏡鏡子自身出現(xiàn)問題，比如各種電子軟鏡因?yàn)槁┧?，液體進(jìn)入CCD，造成CDD底座腐蝕、嚴(yán)重時(shí)CCD損壞、無圖像輸出。而硬鏡出現(xiàn)彎折變形、物鏡碎裂等問題時(shí)，也會(huì)造成無圖像故障。這些問題主要由于診察和手術(shù)治療中以及滅菌消毒中的不規(guī)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(shù)和設(shè)備等限制，出現(xiàn)上述故障的內(nèi)窺鏡大多數(shù)需要外送專業(yè)的維修公司，費(fèi)時(shí)費(fèi)錢。所以，規(guī)范操作十分必要，對(duì)操作人員要定期進(jìn)行嚴(yán)格的培訓(xùn)和考核，以減少此類故障的發(fā)生。還有什么問題就來我們網(wǎng)站http://483177.com解決吧！

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.
