維修流程：環環相扣的精密工序?

Repair process: Precise interlocking processes

一、全面檢測，精準定位?

1、 Comprehensive testing and precise positioning

維修的第一步是對故障鼻竇鏡進行全面檢測。維修工程師借助專業的檢測設備，如光學檢測儀、電路測試儀等，對光學系統、照明系統、機械結構等進行逐一排查。通過光學檢測儀觀察鏡片的清晰度、成像質量，判斷是否存在鏡片損壞、移位等問題；利用電路測試儀檢測光源模塊的電壓、電流，確定電路是否正常。同時，對鏡體的彎曲度、鉗道的通暢性、操作部的靈活性進行細致檢查，準確記錄故障現象與位置，為后續維修提供依據。?

The first step in maintenance is to conduct a comprehensive inspection of the faulty sinus endoscope. Maintenance engineers use professional testing equipment such as optical detectors, circuit testers, etc. to conduct a thorough inspection of optical systems, lighting systems, mechanical structures, etc. Observe the clarity and imaging quality of the lens through an optical detector to determine if there are any issues such as lens damage or displacement; Use a circuit tester to test the voltage and current of the light source module to determine if the circuit is functioning properly. At the same time, a detailed inspection is carried out on the curvature of the mirror body, the smoothness of the clamping channel, and the flexibility of the operating part, accurately recording the fault phenomenon and location, providing a basis for subsequent maintenance. ?

二、拆解清理，謹慎操作?

2、 Disassemble and clean, operate with caution

在明確故障后，需對鼻竇鏡進行拆解。由于鼻竇鏡結構精密，內部零件微小且復雜，拆解過程必須謹慎操作。維修工程師使用專用的精密工具，按照特定順序逐步拆卸各個部件，避免因操作不當造成二次損壞。拆解完成后，對所有零件進行徹底清理，去除表面的污漬、銹跡和殘留雜質。對于光學鏡片，采用無塵布和專用清潔劑輕輕擦拭，確保鏡片表面潔凈無污；對于機械零件，則使用超聲波清洗機進行深度清潔，去除頑固污垢。?

After identifying the malfunction, the sinus endoscope needs to be disassembled. Due to the precise structure of the sinus endoscope and the small and complex internal components, the disassembly process must be handled with caution. Maintenance engineers use specialized precision tools to gradually disassemble each component in a specific order to avoid secondary damage caused by improper operation. After disassembly, thoroughly clean all parts to remove surface stains, rust, and residual impurities. For optical lenses, gently wipe them with a dust-free cloth and specialized cleaning agent to ensure that the surface of the lens is clean and free of dirt; For mechanical parts, ultrasonic cleaning machines are used for deep cleaning to remove stubborn dirt. ?

三、修復更換，技術攻堅?

3、 Repair and replacement, technical breakthroughs

針對檢測出的故障部件，維修工程師根據損壞程度選擇修復或更換。對于輕微劃痕的光學鏡片，可采用拋光技術進行修復，通過精細的打磨和拋光處理，恢復鏡片的光潔度和透光率；若鏡片損壞嚴重，則需更換同規格的全新鏡片，并重新進行光學校準，確保成像清晰、準確。對于斷裂的光纖，需使用光纖熔接機進行熔接修復，將斷裂的光纖兩端精確對接并熔合，恢復光傳導性能；若光纖老化嚴重，則整體更換新的光纖束。對于機械結構故障，如鏡體彎曲，可通過專業的矯形設備進行校正；鉗道堵塞則使用專用的疏通工具進行清理，必要時更換損壞的鉗道部件；操作部失靈的問題，多是由于內部彈簧、齒輪等零件磨損，需更換相應零件并重新調試，確保操作靈活順暢。?

For the detected faulty components, maintenance engineers choose to repair or replace them according to the degree of damage. For optical lenses with slight scratches, polishing technology can be used for repair, restoring the smoothness and transparency of the lens through fine polishing and polishing treatment; If the lens is severely damaged, it is necessary to replace it with a brand new lens of the same specification and perform optical calibration again to ensure clear and accurate imaging. For broken optical fibers, a fiber fusion splicer needs to be used for fusion repair, accurately docking and fusing the two ends of the broken fiber to restore its optical conductivity; If the fiber optic aging is severe, replace the entire fiber optic bundle with a new one. For mechanical structural failures, such as mirror bending, they can be corrected using professional orthopedic equipment; If the clamping channel is blocked, use specialized dredging tools to clean it, and replace damaged clamping channel components if necessary; The problem of malfunction in the operation department is often due to wear and tear of internal springs, gears, and other parts, which require replacement of corresponding parts and re debugging to ensure flexible and smooth operation. ?

四、組裝調試，嚴格檢驗?

4、 Assembly and debugging, strict inspection

完成部件修復或更換后，將鼻竇鏡進行重新組裝。組裝過程同樣需要嚴格按照操作規范進行，確保各個部件安裝到位、連接緊密。組裝完成后，對鼻竇鏡進行全面調試，檢查光學系統的成像質量、照明系統的亮度和穩定性、機械結構的操作性能等。通過模擬實際使用場景，對鼻竇鏡進行多次測試，確保各項功能正常。最后，按照醫療器械的質量標準進行嚴格檢驗，只有通過所有檢測項目的鼻竇鏡，才能判定為維修合格，重新投入臨床使用。

After completing component repair or replacement, reassemble the sinus endoscope. The assembly process also needs to strictly follow the operating specifications to ensure that each component is installed in place and connected tightly. After assembly, conduct comprehensive debugging of the sinus endoscope, check the imaging quality of the optical system, the brightness and stability of the lighting system, and the operational performance of the mechanical structure. By simulating actual usage scenarios and conducting multiple tests on the sinus endoscope, ensure that all functions are functioning properly. Finally, strict inspection is carried out according to the quality standards of medical devices. Only sinus endoscopes that pass all testing items can be judged as repaired and put back into clinical use.
