常见故障及维修方法

Common faults and maintenance methods

图像故障

Image malfunction

图像模糊：可能是镜头污染、损坏或摄像头故障所致。对于镜头污染，可用专用的清洁剂和擦拭工具进行清洁；若镜头损坏，则需更换镜头。摄像头故障则可能需要检查电路连接、传感器等部件，必要时更换摄像头模块。

Image blur: It may be caused by lens contamination, damage, or camera malfunction. For lens contamination, specialized cleaning agents and wiping tools can be used for cleaning; If the lens is damaged, it needs to be replaced. If the camera malfunctions, it may be necessary to check the circuit connections, sensors, and other components, and replace the camera module if necessary.

图像有黑斑或暗区：通常是光源问题，如灯泡老化、损坏或光路堵塞。可先更换灯泡，若问题仍未解决，则需检查光路系统，清理光路中的杂物或更换损坏的光学元件。

Images with black spots or dark areas: usually due to lighting issues, such as aging or damaged light bulbs, or blocked light paths. You can replace the light bulb first. If the problem still persists, you need to check the light path system, clean the debris in the light path, or replace damaged optical components.

图像色彩失真：可能是摄像头的白平衡设置不当或传感器故障。可尝试重新调整白平衡，若无法解决，则可能需要更换传感器。

Image color distortion: It may be due to improper white balance setting of the camera or sensor malfunction. You can try readjusting the white balance. If it doesn't work, you may need to replace the sensor.

机械故障

mechanical failure

插入管弯曲或破损：多因使用不当或外力挤压造成。轻微的弯曲可通过专用的矫正工具进行修复；若插入管破损，则需更换新的插入管。

Bent or damaged insertion tube: often caused by improper use or external pressure. Minor bends can be repaired using specialized correction tools; If the insertion tube is damaged, a new insertion tube needs to be replaced.

活检钳等附件无法正常工作：可能是钳头磨损、弹簧失灵或传动机构故障。可更换磨损的钳头、修复或更换弹簧，以及检查和修复传动机构。

The accessories such as biopsy forceps cannot work properly: it may be due to worn forceps heads, spring failure, or transmission mechanism malfunction. Replace worn pliers, repair or replace springs, and inspect and repair transmission mechanisms.

设备按钮或开关失灵：一般是由于按钮磨损、电路连接不良或开关损坏。可更换按钮，检查并修复电路连接，或更换开关。

Equipment button or switch malfunction: usually due to button wear, poor circuit connection, or damaged switch. Replace buttons, check and repair circuit connections, or replace switches.

电气故障

electrical fault

设备无法开机：首先检查电源适配器是否正常工作，电源线是否连接良好。若电源部分正常，则可能是设备内部的电源板故障，需要检查电源板上的保险丝、电容、变压器等元件，更换损坏的元件。

The device cannot be turned on: First, check if the power adapter is working properly and if the power cord is connected properly. If the power supply is normal, it may be a fault in the internal power board of the device. It is necessary to check the fuses, capacitors, transformers and other components on the power board and replace the damaged components.

设备运行中出现死机或报错：可能是软件故障或硬件故障。尝试重启设备，若问题依旧存在，可更新设备的软件版本或恢复出厂设置。若软件更新无效，则可能是硬件故障，如内存故障、主板故障等，需要进一步检查和更换相应的硬件部件。

If the device crashes or reports an error during operation, it may be due to software or hardware failure. Try restarting the device. If the problem persists, you can update the software version of the device or restore the factory settings. If the software update is ineffective, it may be a hardware failure, such as memory failure, motherboard failure, etc., and further inspection and replacement of corresponding hardware components are required.

维修后的检测与校准

Inspection and calibration after repair

性能检测：维修完成后，需对内窥镜设备进行全面的性能检测，包括图像质量、光源强度、机械运动、电气功能等方面。确保设备各项性能指标符合厂家规定的标准。

Performance testing: After the maintenance is completed, a comprehensive performance testing of the endoscope equipment is required, including image quality, light source intensity, mechanical motion, electrical function, and other aspects. Ensure that all performance indicators of the equipment meet the standards specified by the manufacturer.

校准：根据设备的类型和功能，进行必要的校准工作，如白平衡校准、焦距校准、压力校准等。校准工作需使用专业的校准设备和工具，并按照厂家的校准流程进行操作。

Calibration: Perform necessary calibration work based on the type and function of the equipment, such as white balance calibration, focal length calibration, pressure calibration, etc. Calibration work requires the use of professional calibration equipment and tools, and the operation should be carried out according to the manufacturer's calibration process.

模拟使用测试：在实际使用前，进行模拟使用测试，将内窥镜插入模拟人体器官的模型中，检查设备在不同角度和深度下的工作情况，确保设备能够正常工作，图像清晰，操作灵活。

Simulated usage test: Before actual use, conduct a simulated usage test by inserting the endoscope into a model that simulates human organs, checking the working condition of the equipment at different angles and depths, ensuring that the equipment can work normally, the images are clear, and the operation is flexible.

维修记录与档案管理

Maintenance Records and Archive Management

详细记录维修过程：对每次维修的时间、故障现象、维修方法、更换的备件等信息进行详细记录。维修记录不仅有助于跟踪设备的维修历史，还可为后续的故障分析和维修提供参考。

Detailed record of maintenance process: Record in detail the time, fault symptoms, maintenance methods, and replaced spare parts for each maintenance. Maintenance records not only help track the maintenance history of equipment, but also provide reference for subsequent fault analysis and maintenance.

建立设备维修档案：为每台内窥镜设备建立独立的维修档案，包括设备的基本信息、维修记录、校准记录、保养记录等。通过对维修档案的分析，可以总结设备的故障规律，提前采取预防措施，降低设备故障率。

Establish equipment maintenance records: Establish an independent maintenance record for each endoscope equipment, including basic information, maintenance records, calibration records, maintenance records, etc. By analyzing the maintenance records, it is possible to summarize the fault patterns of the equipment, take preventive measures in advance, and reduce the equipment failure rate.
