醫(yī)用內(nèi)窺鏡系統(tǒng)主要由高清攝像主機(jī)、高清攝像頭、高清監(jiān)視器、冷光源、氣腹機(jī)、高頻電刀、各種內(nèi)窺鏡和其他專(zhuān)用配套手術(shù)器械組成。其中，高清監(jiān)視器、高清攝像主機(jī)、攝像頭、冷光源、氣腹機(jī)、高頻電刀被由上到下放置于腔鏡專(zhuān)用工作臺(tái)車(chē)，移動(dòng)方便，靈活地服務(wù)于不同科室的診察治療。那么監(jiān)視器無(wú)圖像的問(wèn)題是怎么回事呢？下面內(nèi)窺鏡維修公司為您分析：

The medical endoscope system mainly consists of a high-definition camera host, high-definition camera, high-definition monitor, cold light source, pneumoperitoneum machine, high-frequency electric knife, various endoscopes, and other specialized surgical instruments. Among them, high-definition monitors, high-definition camera hosts, cameras, cold light sources, pneumoperitoneum machines, and high-frequency electric knives are placed from top to bottom on a dedicated worktable for endoscopy, which is convenient to move and flexibly serves the diagnosis and treatment of different departments. So what is the problem of no images on the monitor? The endoscope repair company will analyze for you:

故障現(xiàn)象主要是監(jiān)視器無(wú)圖像輸出，可以分為兩種：一種為監(jiān)視器呈黑屏狀態(tài)，無(wú)圖像，無(wú)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(wú)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.

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(wú)正常供電，及時(shí)更換適配器；若正常，重啟設(shè)備，觀察開(kāi)機(jī)自檢畫(huà)面是否正常，如果自檢不通過(guò)則可送至專(zhuān)業(yè)代理商進(jìn)行維修。

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.

現(xiàn)在的醫(yī)用高清液晶顯示器技術(shù)成熟、質(zhì)量可靠，一般故障率很低，出現(xiàn)無(wú)圖像現(xiàn)象的故障絕大多數(shù)是由于信號(hào)輸入故障造成的。此時(shí)，應(yīng)從簡(jiǎn)單的操作入手，先檢查液晶顯示器的信號(hào)輸入模式是否設(shè)置正確，常用信號(hào)輸入模式有DVI、HDMI、S-Video、SDI等格式。

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, check if the signal input mode of the LCD display is set correctly. Common signal input modes include DVI, HDMI, S-Video, SDI, and other formats.

然后查看信號(hào)傳輸電纜的種類(lèi)及其在顯示器上的接入端口種類(lèi)名稱(chēng)來(lái)確定輸入模式，檢查顯示器輸入菜單中的信號(hào)格式是否設(shè)置成相同，若不同則重新設(shè)置后故障大多數(shù)可消除。

Then, check the type of signal transmission cable and the name of its input port on the monitor to determine the input mode. Check whether the signal format in the monitor input menu is set to the same. If different, reset it and most of the faults can be eliminated.

反之，則需要沿著信號(hào)傳輸路徑反向檢查，查看攝像機(jī)主機(jī)與監(jiān)視器之間的信號(hào)傳輸電纜是否脫落或損壞，檢查攝像機(jī)主機(jī)和攝像頭是否正常工作，如果上述設(shè)備出現(xiàn)故障，則需要及時(shí)更換備用部件并進(jìn)行專(zhuān)業(yè)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.

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(wèn)題，比如各種電子軟鏡因?yàn)槁┧后w進(jìn)入CCD，造成CDD底座腐蝕、嚴(yán)重時(shí)CCD損壞、無(wú)圖像輸出。而硬鏡出現(xiàn)彎折變形、物鏡碎裂等問(wèn)題時(shí)，也會(huì)造成無(wú)圖像故障。這些問(wèn)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。

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.

例如，泌尿外科手術(shù)中使用鈥激光時(shí)，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(dòng)力系統(tǒng)工作部誤撞，造成物鏡碎裂；或者消毒滅菌時(shí)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(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(zhuān)業(yè)的維修公司，費(fèi)時(shí)費(fèi)錢(qián)。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(lèi)故障的發(fā)生。更多相關(guān)事項(xiàng)就來(lái)我們網(wǎng)站http://caorui.com.cn咨詢(xún)！

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.
