宮腔鏡作為婦科診療的核心設備，其穩定性直接影響手術安全與診斷精度。維修過程中，技術人員需通過系統性檢測，精準定位故障根源。以下從光學系統、機械結構、電氣功能及使用環境四大維度，解析宮腔鏡維修的常見問題與排查要點。

　　As the core equipment for gynecological diagnosis and treatment, hysteroscopy's stability directly affects surgical safety and diagnostic accuracy. During the maintenance process, technicians need to conduct systematic testing to accurately locate the root cause of the fault. The following analyzes the common problems and troubleshooting points of hysteroscope maintenance from four dimensions: optical system, mechanical structure, electrical function, and usage environment.

　　一、光學系統故障

　　1、 Optical system malfunction

　　圖像模糊或缺失：

　　Blurred or missing image:

　　鏡頭污染：血液、組織殘留物附著鏡面，需使用專用清洗劑與無塵布擦拭，避免劃傷光學涂層。

　　Lens contamination: Blood and tissue residues adhere to the mirror surface, and special cleaning agents and dust-free cloths should be used to wipe to avoid scratching the optical coating.

　　光纖斷裂：導光束彎曲半徑過小或頻繁拉扯導致內部光纖斷裂，表現為光斑不均或亮度衰減，需更換導光束組件。

　　Fiber optic fracture: The internal fiber optic fracture is caused by the bending radius of the guide beam being too small or frequent pulling, resulting in uneven light spot or brightness attenuation, and the guide beam component needs to be replaced.

　　CCD傳感器故障：圖像出現雪花點、色塊或無信號，可能因靜電擊穿或進水短路，需檢測傳感器電路板。

　　CCD sensor malfunction: Snowflake spots, color blocks, or no signal appear in the image, which may be due to electrostatic breakdown or water short circuit. The sensor circuit board needs to be tested.

　　色彩失真：

　　Color distortion:

　　白平衡失效或光學濾鏡老化，需校準色溫參數或更換濾鏡模塊。

　　White balance failure or aging of optical filters requires calibration of color temperature parameters or replacement of filter modules.

　　二、機械結構損傷

　　2、 Mechanical structural damage

　　插入部卡滯：

　　Insertion stuck:

　　彎曲管內部鋼絲斷裂或潤滑不足，導致操作手柄旋轉阻力增大，需拆卸清洗并重新注脂。

　　The steel wire inside the bent tube is broken or poorly lubricated, resulting in increased resistance to the rotation of the operating handle. It needs to be disassembled, cleaned, and re greased.

　　鏡鞘變形：因碰撞或高溫消毒變形，需用專用校準工具修復或更換鞘管。

　　Mirror sheath deformation: Due to collision or high-temperature disinfection deformation, specialized calibration tools are needed to repair or replace the sheath tube.

　　密封失效：

　　Sealing failure:

　　O型圈老化或安裝不到位，引發漏水或氣溶膠泄漏，需更換密封件并檢測氣密性。

　　O-ring aging or improper installation may cause water leakage or aerosol leakage, requiring replacement of seals and testing of air tightness.

　　三、電氣功能異常

　　3、 Abnormal electrical function

　　電源故障：

　　Power failure:

　　主機無法開機或頻繁重啟，可能因電源模塊電容鼓包或保險絲熔斷，需萬用表檢測電壓輸出。

　　The host cannot be turned on or restarts frequently, which may be due to the power module capacitor bulging or fuse blowing. A multimeter is needed to detect the voltage output.

　　信號傳輸中斷：

　　Signal transmission interruption:

　　連接線接觸不良或接口氧化，導致圖像閃斷，需清潔接口并加固連接。

　　Poor contact of the connecting wire or oxidation of the interface may cause image flashing, and the interface needs to be cleaned and the connection reinforced.

　　功能按鍵失靈：

　　Function button malfunction:

　　按鈕碳膜磨損或主板排線斷裂，需更換按鍵組件或重新焊接排線。

　　The carbon film on the button is worn or the motherboard wiring is broken, and the button components need to be replaced or the wiring needs to be re soldered.

　　四、使用環境與操作影響

　　4、 Impact of usage environment and operation

　　高溫高濕損害：

　　High temperature and high humidity damage:

　　長期置于濕熱環境導致鏡體發霉，需用除濕柜存儲并定期通電除霧。

　　Long term exposure to humid and hot environments can cause mold growth on the mirror body. It needs to be stored in a dehumidification cabinet and regularly powered on for defogging.

　　消毒不規范：

　　Improper disinfection:

　　化學浸泡時間過長腐蝕金屬部件，或高溫高壓滅菌未遵循說明書，需培訓使用人員規范消毒流程。

　　If the chemical immersion time is too long and corrodes metal parts, or if the high-temperature and high-pressure sterilization does not follow the instructions, the user needs to be trained to standardize the disinfection process.

　　粗暴操作：

　　Rough operation:

　　強行插入導致鏡鞘彎曲，或未解鎖即拔出鏡頭，需加強操作培訓與設備保護意識。

　　Forceful insertion may cause the sheath to bend, or the lens to be pulled out without unlocking. It is necessary to strengthen operational training and equipment protection awareness.

　　五、維修流程與質量控制

　　5、 Maintenance process and quality control

　　故障復現：

　　Fault reproduction:

　　連接模擬主機，復現用戶描述的故障現象，縮小排查范圍。

　　Connect the simulated host, reproduce the fault symptoms described by the user, and narrow down the scope of investigation.

　　分模塊檢測：

　　Module detection:

　　采用“光學-機械-電氣”順序拆解，記錄關鍵部件狀態。

　　Disassemble in the order of "optical mechanical electrical" and record the status of key components.

　　備件匹配：

　　Spare parts matching:

　　選用原廠規格配件，如導光束直徑、鏡鞘長度需與主機兼容。

　　Select original specifications of accessories, such as the diameter of the light guide beam and the length of the sheath, which should be compatible with the host.

　　性能驗證：

　　Performance verification:

　　維修后需進行分辨率測試、漏水試驗及老化運行，確保參數達標。

　　After maintenance, resolution testing, leakage testing, and aging operation are required to ensure that the parameters meet the standards.

　　六、預防性維護建議

　　6、 Preventive maintenance recommendations

　　日常保養：

　　Daily maintenance:

　　每臺手術后立即清洗鏡頭，避免干涸污漬，使用酶洗劑浸泡機械部件。

　　Immediately clean the lens after each surgery to avoid drying up stains, and soak the mechanical components in enzyme detergent.

　　定期校準：

　　Regular calibration:

　　每半年由工程師檢測光學對準度與電氣參數，提前更換易損件。

　　Every six months, engineers inspect the optical alignment and electrical parameters, and replace vulnerable parts in advance.

　　建立檔案：

　　Establish archives:

　　記錄設備使用時長、維修歷史及更換部件，為壽命預測提供依據。

　　Record the duration of equipment use, maintenance history, and replacement of parts to provide a basis for life prediction.

　　宮腔鏡維修需結合精密檢測與臨床使用反饋，才能實現高效修復。通過規范化操作培訓、科學化維護管理，可顯著延長設備壽命，降低故障率，為婦科診療提供可靠保障。

　　Hysteroscopy maintenance requires a combination of precision testing and clinical feedback to achieve efficient repair. Through standardized operation training and scientific maintenance management, the lifespan of equipment can be significantly extended, the failure rate can be reduced, and reliable guarantees can be provided for gynecological diagnosis and treatment.
