判断内窥镜是否需要维修，可通过以下方面进行观察：

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

　　图像问题：图像太黑、不清晰、模糊、有条纹、颜色不正确或存在干扰，可能需清洁镜片或检查内部电路。

　　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.

　　气水喷嘴堵塞：按下送气送水按钮后，水流不畅，需检查并清理喷嘴及气水管道。

　　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.

　　外观异常：镜体有凹痕、弯折、烧痕或撞击痕迹，需根据损坏情况更换部件。

　　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.

　　声音异常：轻轻摇动镜体可听到明显声音，表明内部零件松动，需拆开维修。

　　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：如冷光源灯泡不亮、监视器无图像显示等，需检查相关部件及电路。

　　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，定期保养和检查内窥镜也是预防故障的重要措施，包括外部清洁、拆机检查各部件之间的松动关系等。在使用过程中，如发现以上任何问题，应及时联系专业维修人员进行检查和维修，以确保内窥镜的正常使用和延长其使用寿命

　　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
