内窥镜设备作为医疗诊断和治疗的重要工具，其维修保养直接关系到设备使用寿命及患者诊疗安全。医疗机构需建立科学管理体系，确保设备处于最佳运行状态。日常维护需遵循操作规范，使用后立即进行预处理，防止生物膜形成。预处理包括流动水冲洗表面污物，配合专用软毛刷轻柔擦拭镜体，避免划伤光学组件。清洗时应拆卸可分离部件，如活检阀门、吸引按钮，使用多酶清洗液浸泡五分钟，水温控制在四十摄氏度以下，防止胶质凝固。清洗后采用全管道灌流系统冲洗内腔，确保无组织残留，

　　As an important tool for medical diagnosis and treatment, the maintenance of endoscopic equipment directly affects the service life of the equipment and the safety of patient diagnosis and treatment. Medical institutions need to establish a scientific management system to ensure that equipment is in optimal operating condition. Daily maintenance should follow operating procedures, and pre-treatment should be carried out immediately after use to prevent biofilm formation. Pre treatment includes rinsing surface dirt with flowing water and gently wiping the mirror body with a specialized soft bristled brush to avoid scratching the optical components. When cleaning, detachable components such as biopsy valves and suction buttons should be disassembled and soaked in a multi enzyme cleaning solution for five minutes. The water temperature should be controlled below 40 degrees Celsius to prevent gel solidification. After cleaning, use a full pipeline irrigation system to flush the inner cavity to ensure no tissue residue,

　　消毒流程需严格参照《医疗机构消毒技术规范》，根据设备材质选择低温等离子灭菌或戊二醛浸泡。采用2%碱性戊二醛浸泡消毒时，需确保完全浸没，消毒时间不少于四十五分钟，灭菌时间达到十小时。消毒后使用无菌蒸馏水彻底冲洗，残留消毒剂可能引发患者黏膜刺激，干燥环节采用压力气枪吹干所有管腔，专用擦拭布吸除表面水分，存放前确认各关节活动自如，无异常摩擦音。

　　The disinfection process should strictly follow the "Technical Specifications for Disinfection of Medical Institutions", and choose low-temperature plasma sterilization or glutaraldehyde immersion according to the equipment material. When using 2% alkaline glutaraldehyde soaking for disinfection, it is necessary to ensure complete immersion, with a disinfection time of not less than 45 minutes and a sterilization time of ten hours. After disinfection, rinse thoroughly with sterile distilled water. Residual disinfectant may cause irritation to the patient's mucous membranes. In the drying process, use a pressure air gun to blow dry all the lumens, and use a dedicated wiping cloth to absorb surface moisture. Before storage, confirm that all joints move freely and there are no abnormal friction sounds.

　　定期保养需建立设备档案，记录使用次数和维修情况。每季度进行光学系统检测，使用分辨率测试卡评估成像清晰度，MTF值低于0.6需进行光路校准。导光東维护应检查纤维断裂情况，暗室环境下观察光斑均匀性，发现黑点超过总面积的5%需更换光纤束。气密性检测每月实施，将内镜完全浸入水中，连接测漏器加压至50kPa，观察两分钟内有无连续气泡产生。发现微小渗漏应立即停用，避免液体侵入导致电路短路，

　　Regular maintenance requires the establishment of equipment files, recording the frequency of use and maintenance status. Perform optical system testing every quarter, evaluate imaging clarity using resolution test cards, and perform optical path calibration if MTF value is below 0.6. The maintenance of the light guide should check for fiber breakage and observe the uniformity of the light spot in a dark room environment. If black spots exceed 5% of the total area, the fiber bundle should be replaced. Airtightness testing is conducted monthly, with the endoscope completely immersed in water, connected to a leak detector and pressurized to 50kPa, and observed for continuous bubble formation within two minutes. If a small leak is found, it should be stopped immediately to avoid liquid intrusion causing a short circuit in the circuit,

　　机械传动部件保养包括关节部位润滑，使用医用级硅油每季度保养一次，注意清除旧润滑脂防止结晶。角度控制系统需定期校验，使用角度测量仪核对各方向弯曲角度，偏差超过5需调整钢丝张力。电气系统检测包含光源亮度检测，氙灯光源累计使用五百小时后光强衰减超过30%应更换灯泡，视频处理器雲每半年进行色彩校正，使用标准色卡调试白平衛确保图像色彩还原准确。

　　Mechanical transmission component maintenance includes joint lubrication, using medical grade silicone oil for quarterly maintenance, and paying attention to removing old lubricating grease to prevent crystallization. The angle control system needs to be regularly calibrated, and the bending angles in all directions should be checked using an angle measuring instrument. If the deviation exceeds 5, the wire tension should be adjusted. Electrical system testing includes light source brightness detection. Xenon lamp light sources should be replaced if the light intensity decays by more than 30% after 500 hours of cumulative use. The video processor cloud performs color correction every six months and uses standard color cards to debug the white flat guard to ensure accurate image color reproduction.

　　故障维修需分级处理，-级故障如光源不亮、图像模糊可由院内工程师处理，检查电源连接或重新插拔视频接头。級故障涉及机械结构损坏，如弯曲部钢丝断裂，需原厂技术人员更换专用配件。三级故障如CCD传感器损坏必须返厂维修，运输过程需使用防震箱体并保持恒温环境。维修后需进行完整性能测试，包括最大弯曲角度测试、照明强度检测和图像分辨率验证，各项参数达标后方可重新启用，

　　Fault repair needs to be handled in a graded manner. Level 1 faults such as light source failure and blurry images can be handled by in-house engineers, who can check the power connection or unplug the video connector. The level fault involves mechanical structural damage, such as steel wire breakage in the bent part, which requires original factory technicians to replace specialized accessories. If the CCD sensor is damaged due to a third level fault, it must be returned to the factory for repair. During transportation, a shockproof box should be used and a constant temperature environment should be maintained. After maintenance, a complete performance test is required, including maximum bending angle testing, lighting intensity testing, and image resolution verification. All parameters must meet the standards before they can be reactivated,

　　保养记录应详细记载维护日期、操作人员、使用耗材批号及设备状态，数字化管理系统可设置自动提醒功能，临近保养周期提前预警。储存环境控制温度在20-25℃，湿度维持在30-50%，避免阳光直射。专用储存柜配备空气循环系统，每月进行微生物检测，菌落数不得超过10CFUm。转运过程使用防撞保护套，避免剧烈震动影响精密光学元件。

　　The maintenance records should detail the maintenance date, operator, batch number of consumables used, and equipment status. The digital management system can be equipped with automatic reminder function to provide early warning when the maintenance cycle is approaching. The storage environment should be controlled at a temperature of 20-25 ℃, with humidity maintained at 30-50%, and avoid direct sunlight. The dedicated storage cabinet is equipped with an air circulation system and undergoes monthly microbiological testing, with a maximum bacterial count of 10CFU. Use anti-collision protective covers during transportation to avoid severe vibrations affecting precision optical components.
