經過長期的手術室儀器設備維修，發現故障根據維修難易和故障大小，可分為復雜故障、中等故障和簡單故障。無論何種故障，我們都必須懂得儀器的工作原理，憑借豐富的維修經驗技術處理。

After long-term maintenance of instruments and equipment in the operating room, faults can be classified into complex faults, medium faults, and simple faults based on the difficulty and size of the maintenance. Regardless of the type of malfunction, we must understand the working principle of the instrument and rely on rich maintenance experience to handle it technically.

一、圖像偏色

1、 Image color deviation

在白平衡后和排除其他配套設備的影響下都無法還原景物的顏色時，我們認為可能是由導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，又或者是由攝像頭CCD老化引起。此時我們只需更換內窺鏡顯示器相應的配件則可。

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

二、圖像有干擾

2、 Image interference

一般是因為用電刀等高頻設備的時候對線路產生干擾，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備的時候也會出現干擾條紋，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線了。目前更換原裝進口的3m長的連接導線價格在10000RMB左右。所以內窺鏡顯示器使用過程中盡量避免導線在地上被儀器車或手術車碾過。

Usually, it is because high-frequency equipment such as electric knives interfere with the circuit. At this time, we need to check whether the camera is connected to the shielding wire in the connection. Another situation is that interference fringes may appear when high-frequency equipment is not in use, which is due to the wear and tear of the shielding layer of the connecting signal line due to long-term use. It needs to be determined whether there is a problem with the connection of the camera or whether the entire cable is aging. The former needs to be re welded, while the latter needs to replace the connecting wires. The current price for replacing the original imported 3m long connecting wire is around 10000 RMB. So during the use of endoscopic displays, try to avoid wires being run over by instrument vehicles or surgical carts on the ground.
