判斷內窺鏡是否需要維修，可通過以下方面進行觀察：

　　To determine whether the endoscope needs maintenance, the following aspects can be observed:

　　圖像問題：圖像太黑、不清晰、模糊、有條紋、顏色不正確或存在干擾，可能需清潔鏡片或檢查內部電路。

　　Image issue: The image is too black, unclear, blurry, striped, with incorrect color or interference, which may require cleaning the lenses or checking the internal circuit.

　　氣水噴嘴堵塞：按下送氣送水按鈕后，水流不暢，需檢查并清理噴嘴及氣水管道。

　　Blockage of air-water nozzle: After pressing the air and water supply button, the water flow is not smooth. It is necessary to check and clean the nozzle and air-water pipeline.

　　外觀異常：鏡體有凹痕、彎折、燒痕或撞擊痕跡，需根據損壞情況更換部件。

　　Appearance abnormality: The mirror body has dents, bends, burn marks, or impact marks, and the components need to be replaced according to the damage situation.

　　聲音異常：輕輕搖動鏡體可聽到明顯聲音，表明內部零件松動，需拆開維修。

　　Abnormal sound: Gently shaking the mirror body can make a noticeable sound, indicating that the internal parts are loose and need to be disassembled for repair.

　　功能失效：如冷光源燈泡不亮、監視器無圖像顯示等，需檢查相關部件及電路。

　　Functional failure: If the cold light bulb does not light up or the monitor does not display images, relevant components and circuits need to be checked.

　　此外，定期保養和檢查內窺鏡也是預防故障的重要措施，包括外部清潔、拆機檢查各部件之間的松動關系等。在使用過程中，如發現以上任何問題，應及時聯系專業維修人員進行檢查和維修，以確保內窺鏡的正常使用和延長其使用壽命

　　In addition, regular maintenance and inspection of endoscopes are also important measures to prevent malfunctions, including external cleaning, disassembly and inspection of loose relationships between various components. If any of the above problems are found during use, professional maintenance personnel should be contacted in a timely manner for inspection and repair to ensure the normal use of the endoscope and extend its service life
