在日常的維修工作中，醫用內窺鏡系統故障時有發生，常見故障主要分為圖像顯示故障、內窺鏡故障、其他配套設備和器械故障。下面內窺鏡維修公司主要來講講醫用內窺鏡監視器無圖像現象的維修排查事項。

In daily maintenance work, medical endoscope system failures often occur, and common failures are mainly divided into image display failures, endoscope failures, and other supporting equipment and instrument failures. Below, the endoscope maintenance company will mainly talk about the maintenance and troubleshooting of medical endoscope monitors without image phenomena.

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、針對第一種故障現象

1. For the first fault phenomenon

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至專業代理商進行維修。

Generally, it is considered whether it is caused by a malfunction of the monitor itself or a signal input malfunction. 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.

現在的醫用高清液晶顯示器技術成熟、質量可靠，一般故障率很低，出現無圖像現象的故障絕大多數是由于信號輸入故障造成的。此時，應從簡單的操作入手，先檢查液晶顯示器的信號輸入模式是否設置正確，常用信號輸入模式有DVI、HDMI、S-Video、SDI等格式，然后查看信號傳輸電纜的種類及其在顯示器上的接入端口種類名稱來確定輸入模式，檢查顯示器輸入菜單中的信號格式是否設置成相同，若不同則重新設置后故障大多數可消除。

The current medical high-definition LCD display technology is mature and reliable in quality, with a generally low failure rate. The vast majority of failures without image phenomenon are caused by signal input faults. At this point, starting with a simple operation, first check whether the signal input mode of the LCD display is set correctly. Common signal input modes include DVI, HDMI, S-Video, SDI, and other formats. Then, check the type of signal transmission cable and the name of the input port on the display to determine the input mode. Check whether the signal format in the display input menu is set to the same, If different, most of the faults can be eliminated after resetting.

反之，則需要沿著信號傳輸路徑反向檢查，查看攝像機主機與監視器之間的信號傳輸電纜是否脫落或損壞，檢查攝像機主機和攝像頭是否正常工作，如果上述設備出現故障，則需要及時更換備用部件并進行專業的維修。

On the contrary, it is necessary to reverse check along the signal transmission path, check whether the signal transmission cable between the camera host and the monitor falls off or is damaged, and check whether the camera host and the camera work normally. If the above equipment fails, it is necessary to replace the spare parts in time and carry out professional maintenance.

2、針對第二種故障現象

2. For the second fault phenomenon

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治療中以及滅菌消毒中的不規范操作造成。

Priority should be given to problems with the endoscope mirror itself, such as various electronic soft mirrors leaking water and 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.

例如，泌尿外科手術中使用鈥激光時，操作光纖不到位，擊穿了鏡子管路；硬鏡物鏡被高頻電刀電擊，或被動力系統工作部誤撞，造成物鏡碎裂；或者消毒滅菌時不慎摔碰造成損壞等。

For example, when Holmium laser is used in Urology surgery, the operating optical fiber is not in place and the mirror tube is broken; The hard lens objective is electrocuted by a high-frequency electric knife or accidentally hit by the power system working part, causing the objective to shatter; Or accidentally falling or damaging during disinfection and sterilization.

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專業的維修公司，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。更多相關事項就來我們網站http://www.rxjhq.cn咨詢吧！

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.
