在现代医疗技术的前沿领域，内窥镜设备已成为众多科室不可或缺的诊断与治疗工具。从耳鼻喉科的耳道、鼻腔检查，到胃肠科的消化道内窥，再到泌尿外科的膀胱镜检查等，内窥镜凭借其直观、精准的特性，为医生提供了深入人体内部的 “眼睛”，极大地提高了疾病诊断的准确性和治疗的有效性。然而，如同任何精密设备一样，内窥镜设备在长期频繁使用过程中，难免会出现各类故障，此时，专业的内窥镜设备维修便成为保障医疗工作顺利开展的关键环节。

In the forefront of modern medical technology, endoscopic equipment has become an indispensable diagnostic and therapeutic tool for many departments. From ear, nose, and throat examinations in otolaryngology, to gastrointestinal endoscopy in gastroenterology, and to cystoscopy in urology, endoscopes provide doctors with an intuitive and precise "eye" that penetrates deep into the human body, greatly improving the accuracy of disease diagnosis and the effectiveness of treatment. However, like any precision equipment, endoscopic equipment is inevitably prone to various malfunctions during long-term and frequent use. At this time, professional maintenance of endoscopic equipment becomes a key link to ensure the smooth progress of medical work.

内窥镜设备维修技术要点​

Key points of maintenance technology for endoscopic equipment

光学系统维修技术​

Optical system maintenance technology

镜片清洁与更换：对于镜头镜片上的灰尘、污渍，维修人员通常使用专业的清洁剂和无尘擦拭布进行清洁。清洁时要注意手法轻柔，避免划伤镜片表面。若镜片出现破损或严重磨损，需要进行更换。更换镜片时，要确保新镜片的型号、规格与原镜片一致，并且安装位置准确无误。在安装过程中，要使用专业的工具，如镜片安装夹具，保证镜片的安装精度，避免因安装不当导致图像变形或模糊。​

Lens cleaning and replacement: For dust and stains on lens lenses, maintenance personnel usually use professional cleaning agents and dust-free wiping cloths for cleaning. When cleaning, pay attention to gentle techniques to avoid scratching the surface of the lens. If the lens is damaged or severely worn, it needs to be replaced. When replacing lenses, ensure that the model and specifications of the new lenses are consistent with the original lenses, and that the installation position is accurate. During the installation process, professional tools such as lens installation fixtures should be used to ensure the accuracy of lens installation and avoid image deformation or blurring caused by improper installation.

光学纤维束修复与更换：当光学纤维束出现少量纤维折断时，可以采用熔接技术进行修复。熔接过程需要使用专业的光纤熔接机，将折断的纤维两端进行精确对准和熔接。对于纤维束损坏较为严重的情况，则需要进行整体更换。更换光学纤维束是一项技术要求极高的工作，需要在显微镜下进行操作，确保新纤维束的每一根纤维都能准确连接到相应的接口，并且在插入管内的排布合理，避免出现弯折、扭曲等情况，以保证光线传输的稳定性和图像的清晰度。​

Repair and replacement of optical fiber bundles: When a small amount of fiber breakage occurs in the optical fiber bundle, fusion welding technology can be used for repair. The fusion process requires the use of a professional fiber fusion splicer to accurately align and fuse the two ends of the broken fiber. For cases where the fiber bundle is severely damaged, a complete replacement is required. Replacing optical fiber bundles is a highly technical task that requires operation under a microscope to ensure that each fiber of the new bundle can be accurately connected to the corresponding interface, and arranged reasonably inside the insertion tube to avoid bending, twisting, and other situations, in order to ensure the stability of light transmission and the clarity of the image. ​

插入管修复与更换：对于插入管外表面的轻微磨损或破损，可以使用专用的修补材料进行修复。修复时，要先对破损部位进行清洁和打磨，然后涂抹修补材料，按照规定的工艺进行固化处理。若插入管损坏严重，如钢丝编织层断裂、橡胶层大面积破损等，则需要更换整个插入管。更换插入管需要将内窥镜的操作部、目镜等部件进行拆解，然后将新的插入管准确安装到位，并进行调试，确保插入管的柔韧性、弯曲角度等性能符合要求。​

Insertion tube repair and replacement: For minor wear or damage on the outer surface of the insertion tube, specialized repair materials can be used for repair. When repairing, the damaged area should be cleaned and polished first, and then repair materials should be applied and cured according to the prescribed process. If the insertion tube is severely damaged, such as the breakage of the steel wire weaving layer, extensive damage to the rubber layer, etc., the entire insertion tube needs to be replaced. Replacing the insertion tube requires disassembling the operating part, eyepiece, and other components of the endoscope, accurately installing the new insertion tube in place, and debugging to ensure that the flexibility, bending angle, and other performance of the insertion tube meet the requirements. ​

活检钳道疏通与修复：对于活检钳道堵塞的情况，维修人员首先使用专用的清洗工具，如高压水枪、钳道疏通刷等，对钳道进行彻底清洗。若清洗后仍无法疏通，可能需要使用专业的钳道修复工具，如扩张器、钳道镜等，对钳道内部进行检查和修复。在修复过程中，要注意避免对钳道造成二次损伤，同时确保修复后的钳道密封性良好，能够正常通过活检钳等器械。​

Biopsy forceps channel dredging and repair: For cases of biopsy forceps channel blockage, maintenance personnel first use specialized cleaning tools such as high-pressure water guns, forceps channel dredging brushes, etc. to thoroughly clean the forceps channel. If the blockage still cannot be cleared after cleaning, it may be necessary to use professional forceps repair tools such as dilators, forceps mirrors, etc. to inspect and repair the inside of the forceps. During the repair process, attention should be paid to avoiding secondary damage to the forceps channel, while ensuring that the repaired forceps channel has good sealing and can pass through biopsy forceps and other instruments normally. ​
