內窺鏡設備憑借精密的光學與電子系統，成為醫療診斷、工業檢測等領域的 “透視眼”。但在維修過程中，稍有不慎就可能引發二次損壞，讓原本的故障 “升級”。從拆解到組裝，從檢測到調試，每個環節都暗藏風險。掌握科學的維修方法，才能避開這些 “雷區”，讓設備安全 “康復”。

　　Endoscopic equipment, with its precise optical and electronic systems, has become the "see through eye" in fields such as medical diagnosis and industrial testing. But during the repair process, even a slight carelessness may cause secondary damage, upgrading the original malfunction. From disassembly to assembly, from testing to debugging, every step carries hidden risks. Mastering scientific maintenance methods is necessary to avoid these "minefields" and ensure the safe "recovery" of equipment.

　　拆解環節：像 “拆鐘表” 般小心翼翼

　　Disassembly process: Be cautious like dismantling a clock

　　拆解是維修的第一步，卻也是最易引發二次損壞的階段。內窺鏡內部結構精密，鏡頭、光纖、電路板等部件微小且脆弱，暴力拆卸可能導致鏡頭碎裂、光纖折斷或線路焊點脫落。正確做法是先查閱設備手冊，了解各部件連接方式與固定位置，使用專用工具（如微型螺絲刀、鑷子）精準操作。例如，拆卸鏡頭時，需避免觸碰鏡面，防止留下指紋或劃痕；分離光纖束時，不可過度彎折，應順著其自然彎曲方向輕輕分離，避免因應力集中導致斷裂。若遇到頑固部件，可使用專用溶劑軟化固定膠，切忌強行撬開。

　　Disassembly is the first step in maintenance, but it is also the stage that is most prone to secondary damage. The internal structure of endoscopes is precise, and components such as lenses, fibers, and circuit boards are small and fragile. Violent disassembly may result in lens breakage, fiber breakage, or detachment of circuit solder joints. The correct approach is to first consult the equipment manual, understand the connection methods and fixing positions of each component, and use specialized tools (such as micro screwdrivers and tweezers) for precise operation. For example, when disassembling the lens, avoid touching the mirror surface to prevent leaving fingerprints or scratches; When separating fiber bundles, they should not be excessively bent and should be gently separated along their natural bending direction to avoid breakage caused by stress concentration. If encountering stubborn components, special solvents can be used to soften the fixing adhesive, and do not forcefully pry it open.

　　清潔保養：杜絕 “溫柔的傷害”

　　Cleaning and maintenance: eliminate "gentle harm"

　　清潔是維修的關鍵步驟，但不當操作反而會帶來隱患。鏡頭、導光窗等光學部件對清潔要求極高，使用粗糙的擦拭材料或腐蝕性清潔劑，可能損傷鍍膜，降低透光率。正確的清潔流程應從低風險方法開始：先用無塵氣吹去除表面浮塵，再用鏡頭紙蘸取專用光學清潔劑，沿一個方向輕柔擦拭。對于管道內部，需使用與管徑匹配的軟質毛刷，避免刷頭過硬刮傷內壁。此外，電子元件的清潔更需謹慎，嚴禁使用含水量高的清潔劑，可采用干燥的壓縮空氣吹掃，或使用專用電子清潔劑快速揮發去污。

　　Cleaning is a crucial step in maintenance, but improper operation can actually bring hidden dangers. Optical components such as lenses and light guide windows require extremely high cleaning standards. Using rough wiping materials or corrosive cleaning agents may damage the coating and reduce light transmittance. The correct cleaning process should start with low-risk methods: first, use dust-free air to blow away surface dust, then dip lens paper in specialized optical cleaner and gently wipe in one direction. For the interior of the pipeline, a soft brush that matches the diameter of the pipe should be used to avoid scratching the inner wall with a hard brush head. In addition, the cleaning of electronic components requires more caution. It is strictly prohibited to use cleaning agents with high water content. Dry compressed air can be used for blowing, or specialized electronic cleaning agents can be used for rapid volatilization and decontamination.

　　檢測調試：警惕 “牽一發而動全身”

　　Testing and debugging: Be wary of the saying 'one pull can affect the whole body'

　　故障檢測與調試階段，錯誤的操作可能引發連鎖反應。在未明確故障原因時，盲目通電測試可能導致短路，燒毀電路板；使用不匹配的檢測設備，也可能因電壓、信號干擾損壞敏感元件。因此，檢測前需斷開電源，使用萬用表、示波器等工具進行靜態測量，逐步排查故障點。調試過程中，應遵循 “循序漸進” 原則：從低功率、低強度的測試開始，例如調整光源亮度時，先調至最低檔觀察反應，再逐步升高，避免因瞬間強光沖擊損壞導光纖維或圖像傳感器。同時，每次調試后需記錄數據，便于追溯問題根源。

　　During the fault detection and debugging phase, incorrect operations may trigger a chain reaction. Blindly conducting power on testing without identifying the cause of the malfunction may result in a short circuit and burn out the circuit board; Using mismatched detection equipment may also damage sensitive components due to voltage and signal interference. Therefore, before testing, it is necessary to disconnect the power supply and use tools such as multimeters and oscilloscopes for static measurement to gradually identify the fault point. During the debugging process, the principle of "gradual progress" should be followed: starting from low-power and low-intensity testing, for example, when adjusting the brightness of the light source, first adjust it to the lowest level to observe the reaction, and then gradually increase it to avoid damaging the light fiber or image sensor due to instantaneous strong light impact. At the same time, data should be recorded after each debugging to facilitate tracing the root cause of the problem.

　　組裝還原：細節決定 “成敗”

　　Assembly restoration: details determine 'success or failure'

　　組裝環節看似簡單，實則暗藏風險。部件安裝順序錯誤、螺絲擰得過緊或過松，都可能影響設備性能。例如，鏡頭安裝時若未對準定位槽，可能導致成像模糊；電路板固定螺絲過緊，會造成 PCB 板變形，引發線路斷路。因此，組裝時需嚴格參照維修手冊，按標記或編號歸位部件，并使用扭矩螺絲刀控制螺絲擰緊力度。此外，密封部件（如防水膠圈、密封圈）的安裝至關重要，需確保位置準確、無扭曲變形，否則可能導致設備進水或氣體泄漏，造成更嚴重的損壞。

　　The assembly process may seem simple, but it actually carries hidden risks. Incorrect installation sequence of components, over tightening or over loosening of screws may all affect equipment performance. For example, if the lens is not aligned with the positioning groove during installation, it may cause blurry imaging; Tightening the fixing screws of the circuit board can cause deformation of the PCB board and lead to circuit breakage. Therefore, during assembly, it is necessary to strictly refer to the maintenance manual, locate the components according to the markings or numbers, and use a torque screwdriver to control the tightening force of the screws. In addition, the installation of sealing components (such as waterproof gaskets and sealing rings) is crucial, ensuring accurate positioning and no twisting or deformation, otherwise it may cause water or gas leakage to the equipment, resulting in more serious damage.

　　人員與環境：筑牢維修的 “安全防線”

　　Personnel and Environment: Building a Secure Defense Line for Maintenance

　　避免二次損壞不僅依賴技術，還需重視維修環境與人員培訓。維修區域應保持潔凈、干燥，配備防靜電工作臺、接地手環等設施，防止靜電擊穿電子元件；溫濕度需控制在適宜范圍，避免因潮濕導致電路板受潮短路。維修人員需經過專業培訓，熟悉設備原理與維修規范，嚴禁在不了解結構的情況下 “憑經驗” 操作。同時，建立嚴格的質量檢驗流程，維修完成后需進行多輪測試，包括功能測試、密封性測試、圖像質量檢測等，確保設備恢復正常性能，無潛在隱患。

　　Avoiding secondary damage not only relies on technology, but also requires attention to maintenance environment and personnel training. The maintenance area should be kept clean and dry, equipped with anti-static workstations, grounding wristbands and other facilities to prevent static electricity from penetrating electronic components; The temperature and humidity should be controlled within an appropriate range to avoid short circuits caused by moisture on the circuit board. Maintenance personnel need to undergo professional training, be familiar with equipment principles and maintenance specifications, and are strictly prohibited from operating based on experience without understanding the structure. At the same time, establish a strict quality inspection process, and conduct multiple rounds of testing after maintenance, including functional testing, sealing testing, image quality inspection, etc., to ensure that the equipment returns to normal performance without potential hazards.
