How to repair the common troubles of endoscope display? After a long-term operation room instrument and equipment maintenance, it is found that the fault can be divided into complex fault, medium fault and simple fault according to the maintenance difficulty and fault size. No matter what kind of fault, we must understand the working principle of the instrument and deal with it with rich maintenance experience.

內(nèi)窺鏡顯示器

Endoscopic display

一、圖像偏色

1、 Image skew

在白平衡后和排除其他配套設(shè)備的影響下都無法還原景物的顏色時，我們認(rèn)為可能是由導(dǎo)線老化信號傳遞缺陷引起的，也可能是攝像頭電路元件老化變質(zhì)，又或者是由攝像頭CCD老化引起。此時我們只需更換內(nèi)窺鏡顯示器相應(yīng)的配件則可。

When the color of the scene cannot be restored after the white balance and the influence of other supporting equipment is excluded, we think it may be caused by the aging signal transmission defect of the wire, the aging deterioration of the camera circuit components, or the aging of the camera CCD. At this time, we only need to replace the corresponding accessories of the endoscope display.

二、圖像有干擾

Two. There is interference in the image

一般是因為用電刀等高頻設(shè)備的時候?qū)€路產(chǎn)生干擾，這時候我們要檢查的是攝像頭與連接中的屏蔽線是否有接通。還有一種情況就是沒有使用高頻設(shè)備的時候也會出現(xiàn)干擾條紋，這時候是連接線信號線由于長期使用，屏蔽層磨損。需要看是攝像頭的連接處出問題還是整條線體老化，前者需要重新焊接，而后者則需要更換連接導(dǎo)線了。目前更換原裝進口的3m長的連接導(dǎo)線價格在10000RMB左右。所以內(nèi)窺鏡顯示器使用過程中盡量避免導(dǎo)線在地上被儀器車或手術(shù)車碾過。

Generally, it is because the high-frequency equipment such as electric knife interferes with the line. At this time, we need to check whether the camera is connected to the shield wire in the connection. Another situation is that interference fringes will appear when the high-frequency equipment is not used. At this time, the shielding layer of the connecting line signal line is worn due to long-term use. It depends on whether the connection of the camera is faulty or the whole line is aging. The former needs to be re welded, and the latter needs to replace the connecting wire. At present, the price for replacing the 3M long connecting wire imported from the original factory is about 10000 RMB. Therefore, during the use of the endoscopic display, try to avoid the wires being run over by the instrument car or the surgical vehicle on the ground.
