內窺鏡設備作為精密醫療器械，其維修需結合結構特點與故障類型，采用針對性的處理方式，以保障設備性能穩定。以下是常見的維修方式說明。

　　Endoscopic equipment, as a precision medical device, requires targeted maintenance based on its structural characteristics and fault types to ensure stable equipment performance. The following are common repair methods.

　　日常清潔與保養是預防故障的基礎。使用后需及時對插入部、操作部進行清潔，先用柔軟紗布擦拭表面污漬，再用專用清洗劑浸泡，去除殘留的體液、組織碎屑。對于活檢通道、吸引通道等內部管路，需用高壓水槍沖洗，配合專用毛刷清理內壁，避免堵塞。清潔后需進行消毒處理，根據設備類型選擇合適的消毒方式（如高溫高壓滅菌、化學消毒），消毒過程需嚴格控制時間和溫度，防止部件老化。此外，定期檢查設備連接線、接口的磨損情況，涂抹專用潤滑劑保持旋鈕、按鈕的靈活性，可減少機械故障的發生。

　　Daily cleaning and maintenance are the foundation for preventing malfunctions. After use, it is necessary to clean the insertion and operation parts in a timely manner. First, wipe the surface stains with soft gauze, and then soak them in a special cleaning agent to remove residual body fluids and tissue debris. For internal pipelines such as biopsy channels and suction channels, high-pressure water guns should be used for flushing, and specialized brushes should be used to clean the inner walls to avoid blockage. After cleaning, disinfection treatment is required, and appropriate disinfection methods (such as high-temperature and high-pressure sterilization, chemical disinfection) should be selected according to the type of equipment. The disinfection process should strictly control the time and temperature to prevent component aging. In addition, regularly checking the wear of equipment connecting wires and interfaces, applying specialized lubricants to maintain the flexibility of knobs and buttons, can reduce the occurrence of mechanical failures.

　　光學系統故障的維修需精細操作。若出現圖像模糊、光斑、黑影等問題，可能是物鏡或目鏡污染、劃傷所致，需在潔凈環境下拆解光學鏡頭，用無水乙醇或專用清潔劑擦拭鏡片，去除油污和雜質。若鏡片有輕微劃痕，可采用專業研磨膏進行拋光修復；若損傷嚴重則需更換鏡片，更換時需保證鏡片的中心軸與光路對齊，避免影響成像精度。對于光纖束斷裂導致的圖像暗區，需檢查光纖束的損壞范圍，少量斷絲可通過調整光路補償，斷絲過多則需更換光纖束，更換后需測試透光率，確保圖像亮度均勻。

　　The maintenance of optical system faults requires meticulous operation. If there are problems such as blurred images, light spots, black shadows, etc., it may be caused by contamination or scratches on the objective or eyepiece. The optical lens should be disassembled in a clean environment and wiped with anhydrous ethanol or specialized cleaning agents to remove oil stains and impurities. If there are slight scratches on the lens, professional grinding paste can be used for polishing and repair; If the damage is severe, the lens needs to be replaced. When replacing, it is necessary to ensure that the central axis of the lens is aligned with the optical path to avoid affecting the imaging accuracy. For image dark areas caused by fiber optic bundle breakage, the damage range of the fiber optic bundle needs to be checked. A small number of broken wires can be compensated by adjusting the optical path. If there are too many broken wires, the fiber optic bundle needs to be replaced. After replacement, the transmittance needs to be tested to ensure uniform image brightness.

　　機械部件故障的維修注重結構復位。插入部彎曲角度不足或卡頓，多因內部鋼絲、牽引繩斷裂或滑輪磨損，需拆解彎曲部，更換斷裂的鋼絲，潤滑滑輪軸，調整牽引繩的張力，確保彎曲動作順暢。活檢鉗通道堵塞或漏水，可能是通道內壁破損或接口密封不良，需檢查通道是否有異物堵塞，用專用工具疏通；若密封件老化，需更換硅膠密封圈，安裝時確保密封面平整，防止滲漏。操作部旋鈕、按鈕失靈，可能是內部彈簧、卡扣損壞，需拆解后更換對應部件，測試操作手感，保證開關動作準確到位。

　　The maintenance of mechanical component failures focuses on structural reset. Insufficient bending angle or jamming of the insertion part is often caused by internal wire or traction rope breakage or pulley wear. It is necessary to disassemble the bending part, replace the broken wire, lubricate the pulley shaft, adjust the tension of the traction rope, and ensure smooth bending action. The blockage or leakage of the biopsy forceps channel may be due to damage to the inner wall of the channel or poor sealing of the interface. It is necessary to check whether there are foreign objects blocking the channel and use specialized tools to clear it; If the sealing component is aging, it is necessary to replace the silicone sealing ring. During installation, ensure that the sealing surface is flat to prevent leakage. The knob and button of the operating part are malfunctioning, possibly due to damage to the internal spring and buckle. It is necessary to disassemble and replace the corresponding components, test the operating feel, and ensure that the switch action is accurate and in place.

　　電路系統故障的維修需專業檢測。設備無法開機、指示燈不亮，可能是電源線、電源適配器故障，需用萬用表檢測電壓輸出是否正常，更換損壞的電源線或適配器。圖像處理器無信號輸出，需檢查信號線接口是否松動、氧化，用酒精擦拭接口后重新連接；若為電路板故障，需通過專用檢測設備定位故障元件（如電容鼓包、電阻燒毀），更換同型號元件后進行電路導通測試，確保無短路、斷路現象。對于傳感器、攝像頭等電子部件故障，需采用替換法排查，更換損壞部件后校準參數，保證圖像色彩、清晰度符合標準。

　　The maintenance of circuit system faults requires professional testing. The device cannot be turned on or the indicator light is not on, which may be due to a fault in the power cord or power adapter. Use a multimeter to check if the voltage output is normal and replace the damaged power cord or adapter. The image processor has no signal output. It is necessary to check whether the signal line interface is loose or oxidized. Wipe the interface with alcohol and reconnect it; If it is a circuit board fault, specialized testing equipment should be used to locate the faulty component (such as capacitor bulges or resistor burnout), replace it with a component of the same model, and conduct a circuit continuity test to ensure that there are no short circuits or open circuits. For electronic component failures such as sensors and cameras, replacement methods should be used to troubleshoot. After replacing damaged components, parameters should be calibrated to ensure that image color and clarity meet standards.

　　故障后的校準與調試不可忽視。維修完成后需對設備進行全面校準，包括光學系統的焦距、白平衡調整，確保圖像清晰、色彩真實；機械部分需測試彎曲角度、鉗道通暢性，保證操作功能正常；電路系統需檢測各接口的電壓、電流，確認符合設備參數要求。校準后需進行模擬使用測試，連續運行設備一段時間，觀察是否有異常發熱、異響，確保維修后的穩定性。

　　Calibration and debugging after a malfunction cannot be ignored. After the maintenance is completed, the equipment needs to be fully calibrated, including adjusting the focal length and white balance of the optical system, to ensure clear images and true colors; The mechanical part needs to be tested for bending angle and the smoothness of the clamping channel to ensure normal operation function; The circuit system needs to detect the voltage and current of each interface to confirm compliance with equipment parameter requirements. After calibration, a simulated usage test is required to run the equipment continuously for a period of time, observing for any abnormal heating or noise to ensure stability after maintenance.
