椎间孔镜作为现代脊柱微创手术的核心器械，其精密结构决定了维修工作的复杂性。当这台集光学、机械、电子技术于一体的设备出现故障时，维修人员需建立系统化的配件更换方案。从临床使用反馈与技术文档分析，可将维修配件分为六大核心模块。

　　As the core instrument of modern minimally invasive spinal surgery, the precision structure of intervertebral foramen endoscope determines the complexity of maintenance work. When this equipment that integrates optical, mechanical, and electronic technologies malfunctions, maintenance personnel need to establish a systematic replacement plan for parts. Based on clinical feedback and technical documentation analysis, maintenance parts can be divided into six core modules.

　　光学系统配件构成视觉传递链路。物镜组作为成像起点，其多组柱状透镜通过不锈钢管固定，壁厚仅0.1毫米的管体在受到外力冲击时易变形，导致透镜移位。当出现图像模糊或彩虹现象时，需整体更换物镜系统。中继镜组中的棱镜与窗口镜片，在长期消毒过程中可能产生膜层脱落，需采用真空镀膜工艺修复。目镜端的色环与光锥，负责色彩还原与光束整形，其精密配合公差需控制在0.02毫米以内。

　　Optical system components form the visual transmission chain. The objective lens group serves as the starting point for imaging, with multiple sets of cylindrical lenses fixed in stainless steel tubes. The tube body, with a wall thickness of only 0.1 millimeters, is prone to deformation when subjected to external impact, resulting in lens displacement. When image blurring or rainbow phenomenon occurs, the entire objective lens system needs to be replaced. The prisms and window lenses in the relay lens group may experience film peeling during long-term disinfection and require vacuum coating technology for repair. The color ring and cone at the eyepiece end are responsible for color reproduction and beam shaping, with a precision fit tolerance controlled within 0.02 millimeters.

　　照明通路配件保障手术视野清晰。光纤组件作为光能载体，采用石英材质多模光纤，在频繁弯折使用中易出现断裂。当光源亮度衰减超过30%时，需检测光纤耦合效率。冷光源模块中的LED芯片，其色温稳定性直接影响手术视野真实性，当色温漂移超过500K时必须更换。导光束接头的陶瓷插芯，需确保与光源接口的同轴度，微小偏差都会导致光斑畸变。

　　Lighting pathway accessories ensure clear surgical field of view. Fiber optic components, as carriers of light energy, use quartz material multimode fibers, which are prone to breakage during frequent bending and use. When the brightness attenuation of the light source exceeds 30%, the fiber coupling efficiency needs to be tested. The color temperature stability of the LED chip in the cold light source module directly affects the authenticity of the surgical field of view, and must be replaced when the color temperature drift exceeds 500K. The ceramic plug of the light guide beam connector needs to ensure coaxiality with the light source interface, as even small deviations can cause distortion of the light spot.

　　机械传动配件维持操作精度。工作管采用医用不锈钢经深孔加工而成，内壁粗糙度需达到Ra0.4以下。当前端出现击伤或弯曲时，需采用电解抛光工艺修复。器械通道的硅胶密封件，在反复插拔手术器械后易产生永久变形，导致气密性失效。操作手柄中的角度传感器，其电阻值漂移超过5%将影响导航精度，需进行标定或更换。

　　Mechanical transmission components maintain operational accuracy. The work tube is made of medical grade stainless steel through deep hole machining, and the inner wall roughness needs to reach Ra0.4 or below. When there is damage or bending on the front end, electrolytic polishing technology should be used for repair. The silicone seal of the instrument channel is prone to permanent deformation after repeated insertion and removal of surgical instruments, resulting in air tightness failure. If the resistance value of the angle sensor in the joystick drifts by more than 5%, it will affect the navigation accuracy and needs to be calibrated or replaced.

　　密封防护配件构建安全屏障。物镜系统的环氧树脂密封胶，在高温消毒后易发生黄变，当硬度超过肖氏D80时需彻底清除重新灌封。O型密封圈采用氟橡胶材质，在化学消毒剂浸泡后可能产生溶胀，需定期测量断面直径。防水透气膜作为关键防护件，其孔隙率需控制在30-50纳米之间，既要阻隔液体又要平衡内外压差。

　　Seal protective accessories to build a safety barrier. The epoxy resin sealant of the objective lens system is prone to yellowing after high-temperature disinfection. When the hardness exceeds Shore D80, it needs to be thoroughly removed and re sealed. The O-ring is made of fluororubber material, which may swell after soaking in chemical disinfectants, and the cross-sectional diameter needs to be measured regularly. As a key protective component, the porosity of waterproof breathable membrane needs to be controlled between 30-50 nanometers, which not only blocks liquids but also balances the internal and external pressure difference.

　　电子控制配件保障系统稳定。图像处理板上的CMOS传感器，其暗电流超过0.5nA时将产生噪声点。信号传输线的屏蔽层，在反复弯曲后可能断裂，需用矢量网络分析仪检测特性阻抗。电源模块中的滤波电容，其等效串联电阻超过100毫欧时需更换，避免电压波动影响设备运行。

　　Electronic control accessories ensure system stability. The CMOS sensor on the image processing board will generate noise points when its dark current exceeds 0.5nA. The shielding layer of the signal transmission line may break after repeated bending, and a vector network analyzer is needed to detect the characteristic impedance. When the equivalent series resistance of the filtering capacitor in the power module exceeds 100 milliohms, it needs to be replaced to avoid voltage fluctuations affecting equipment operation.

　　辅助功能配件完善系统集成。吸引器接头的锥度密封面，在长期使用后可能磨损，需用气密检测仪验证泄漏率。可旋转固定架的阻尼轴承，其扭矩衰减超过30%时需更换，确保手术过程中的稳定性。这些辅助配件虽不直接参与核心功能，但对整体性能有着重要影响。

　　Improve system integration with auxiliary functional accessories. The tapered sealing surface of the attractor joint may wear out after long-term use, and it is necessary to verify the leakage rate with an airtight detector. When the torque attenuation of the damping bearing of the rotatable fixed frame exceeds 30%, it needs to be replaced to ensure stability during the surgical process. These auxiliary accessories, although not directly involved in core functions, have a significant impact on overall performance.

　　椎间孔镜维修需要建立标准化配件更换流程。通过故障树分析法定位失效环节，结合设备日志追溯使用记录，可制定出经济高效的维修方案。维修过程中需使用原厂级检测设备，如光斑分析仪、三坐标测量机等，确保修复后的设备性能达到出厂标准。这种系统化的配件管理策略，既能延长设备使用寿命，又能保障临床手术安全。

　　The maintenance of intervertebral foramen endoscope requires the establishment of a standardized accessory replacement process. By using the fault tree analysis method to locate the faulty link and combining it with equipment logs to trace usage records, an economical and efficient maintenance plan can be developed. During the maintenance process, original factory level testing equipment such as spot analyzers and coordinate measuring machines should be used to ensure that the performance of the repaired equipment meets the factory standards. This systematic accessory management strategy can not only extend the service life of equipment, but also ensure the safety of clinical surgery.
