維修流程：環(huán)環(huán)相扣的精密工序?

Repair process: Precise interlocking processes

一、全面檢測(cè)，精準(zhǔn)定位?

1、 Comprehensive testing and precise positioning

維修的第一步是對(duì)故障鼻竇鏡進(jìn)行全面檢測(cè)。維修工程師借助專業(yè)的檢測(cè)設(shè)備，如光學(xué)檢測(cè)儀、電路測(cè)試儀等，對(duì)光學(xué)系統(tǒng)、照明系統(tǒng)、機(jī)械結(jié)構(gòu)等進(jìn)行逐一排查。通過光學(xué)檢測(cè)儀觀察鏡片的清晰度、成像質(zhì)量，判斷是否存在鏡片損壞、移位等問題；利用電路測(cè)試儀檢測(cè)光源模塊的電壓、電流，確定電路是否正常。同時(shí)，對(duì)鏡體的彎曲度、鉗道的通暢性、操作部的靈活性進(jìn)行細(xì)致檢查，準(zhǔn)確記錄故障現(xiàn)象與位置，為后續(xù)維修提供依據(jù)。?

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(jǐn)慎操作?

2、 Disassemble and clean, operate with caution

在明確故障后，需對(duì)鼻竇鏡進(jìn)行拆解。由于鼻竇鏡結(jié)構(gòu)精密，內(nèi)部零件微小且復(fù)雜，拆解過程必須謹(jǐn)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(gè)部件，避免因操作不當(dāng)造成二次損壞。拆解完成后，對(duì)所有零件進(jìn)行徹底清理，去除表面的污漬、銹跡和殘留雜質(zhì)。對(duì)于光學(xué)鏡片，采用無(wú)塵布和專用清潔劑輕輕擦拭，確保鏡片表面潔凈無(wú)污；對(duì)于機(jī)械零件，則使用超聲波清洗機(jī)進(jìn)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(fù)更換，技術(shù)攻堅(jiān)?

3、 Repair and replacement, technical breakthroughs

針對(duì)檢測(cè)出的故障部件，維修工程師根據(jù)損壞程度選擇修復(fù)或更換。對(duì)于輕微劃痕的光學(xué)鏡片，可采用拋光技術(shù)進(jìn)行修復(fù)，通過精細(xì)的打磨和拋光處理，恢復(fù)鏡片的光潔度和透光率；若鏡片損壞嚴(yán)重，則需更換同規(guī)格的全新鏡片，并重新進(jìn)行光學(xué)校準(zhǔn)，確保成像清晰、準(zhǔn)確。對(duì)于斷裂的光纖，需使用光纖熔接機(jī)進(jìn)行熔接修復(fù)，將斷裂的光纖兩端精確對(duì)接并熔合，恢復(fù)光傳導(dǎo)性能；若光纖老化嚴(yán)重，則整體更換新的光纖束。對(duì)于機(jī)械結(jié)構(gòu)故障，如鏡體彎曲，可通過專業(yè)的矯形設(shè)備進(jìn)行校正；鉗道堵塞則使用專用的疏通工具進(jìn)行清理，必要時(shí)更換損壞的鉗道部件；操作部失靈的問題，多是由于內(nèi)部彈簧、齒輪等零件磨損，需更換相應(yīng)零件并重新調(diào)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(diào)試，嚴(yán)格檢驗(yàn)?

4、 Assembly and debugging, strict inspection

完成部件修復(fù)或更換后，將鼻竇鏡進(jìn)行重新組裝。組裝過程同樣需要嚴(yán)格按照操作規(guī)范進(jìn)行，確保各個(gè)部件安裝到位、連接緊密。組裝完成后，對(duì)鼻竇鏡進(jìn)行全面調(diào)試，檢查光學(xué)系統(tǒng)的成像質(zhì)量、照明系統(tǒng)的亮度和穩(wěn)定性、機(jī)械結(jié)構(gòu)的操作性能等。通過模擬實(shí)際使用場(chǎng)景，對(duì)鼻竇鏡進(jìn)行多次測(cè)試，確保各項(xiàng)功能正常。最后，按照醫(yī)療器械的質(zhì)量標(biāo)準(zhǔn)進(jìn)行嚴(yán)格檢驗(yàn)，只有通過所有檢測(cè)項(xiàng)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.
