經(jīng)過長(zhǎng)期的手術(shù)室儀器設(shè)備維修，發(fā)現(xiàn)故障根據(jù)維修難易和故障大小，可分為復(fù)雜故障、中等故障和簡(jiǎn)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(jīng)驗(yàn)技術(shù)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(shè)備的影響下都無法還原景物的顏色時(shí)，我們認(rèn)為可能是由導(dǎo)線老化信號(hào)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(shí)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 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?yàn)橛秒姷兜雀哳l設(shè)備的時(shí)候?qū)€路產(chǎn)生干擾，這時(shí)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(shí)候也會(huì)出現(xiàn)干擾條紋，這時(shí)候是連接線信號(hào)線由于長(zhǎng)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(jìn)口的3m長(zhǎng)的連接導(dǎo)線價(jià)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。

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.
