在现代医疗体系中，内窥镜设备作为诊断与治疗诸多疾病的 “神兵利器”，其重要性不言而喻。无论是胃镜深入胃部探寻病变，还是腹腔镜在腹腔内辅助精准手术，内窥镜都凭借独特的可视化功能，为医疗工作者提供关键的诊断依据，极大提升了医疗服务的精准性与有效性。然而，这类精密仪器在高频使用过程中，极易出现各类故障，此时，专业的内窥镜设备维修便成为保障医疗流程顺畅、维系患者健康的重要环节。

In the modern medical system, the importance of endoscopic equipment as a "divine weapon" for diagnosing and treating many diseases is self-evident. Whether it is gastroscopy exploring lesions in the stomach or laparoscopy assisting precise surgery in the abdominal cavity, endoscopes provide key diagnostic basis for medical workers with their unique visualization function, greatly improving the accuracy and effectiveness of medical services. However, such precision instruments are prone to various malfunctions during high-frequency use, and professional maintenance of endoscopic equipment becomes an important link in ensuring smooth medical processes and maintaining patient health.

维修流程与技术手段​

Maintenance process and technical means

故障检测与诊断​

Fault detection and diagnosis

维修人员接到故障内窥镜后，首先会进行全面的外观检查，查看是否有明显的物理损伤，如外壳破裂、线缆破损等。接着，使用专业的检测设备对内窥镜的光学、电子、机械系统进行详细测试。对于光学系统，通过光学检测仪器评估图像质量、物镜焦距、导光束亮度等参数；针对电子系统，利用示波器、信号发生器等设备检测信号传输情况，判断电子元件是否正常工作；在机械结构方面，通过手动操作弯曲部、活检钳道等，检查其运动是否顺畅，有无卡顿、异常阻力等现象。结合检测数据与实际观察，准确判断故障类型与具体位置。​

After receiving the faulty endoscope, the maintenance personnel will first conduct a comprehensive visual inspection to check for any obvious physical damage, such as shell rupture, cable damage, etc. Next, use professional testing equipment to conduct detailed tests on the optical, electronic, and mechanical systems of the endoscope. For optical systems, parameters such as image quality, objective lens focal length, and guide beam brightness are evaluated using optical detection instruments; For electronic systems, use equipment such as oscilloscopes and signal generators to detect signal transmission and determine whether electronic components are working properly; In terms of mechanical structure, manually operate the bending part, biopsy forceps, etc. to check whether their movement is smooth, whether there are any jamming, abnormal resistance, and other phenomena. By combining detection data with actual observation, accurately determine the type and specific location of the fault. ​

维修与更换零部件​

Repair and replacement of parts

根据故障诊断结果，维修人员采取相应的维修措施。对于光学系统故障，若物镜磨损较轻，可通过专业的研磨、抛光工艺进行修复；镜片污染则需使用专用的清洁剂进行精细清洗；若导光束断裂，需精确更换受损的导光纤维。电子系统故障维修时，对于损坏的图像传感器、集成电路等元件，需在防静电环境下进行精准焊接更换；修复信号传输线路时，要仔细排查断路、短路点，进行焊接或线缆更换。机械结构故障处理中，弯曲部钢丝断裂需更换全新钢丝，并重新调试弯曲角度；角度控制装置的磨损部件要进行更换或修复，确保角度控制的准确性；活检钳道堵塞则采用专用的疏通工具和清洗液进行清理。​

According to the fault diagnosis results, maintenance personnel take corresponding maintenance measures. For optical system failures, if the objective lens wears lightly, it can be repaired through professional grinding and polishing processes; Lens contamination requires the use of specialized cleaning agents for fine cleaning; If the light guide beam breaks, the damaged light guide fiber needs to be replaced accurately. When repairing electronic system malfunctions, damaged components such as image sensors and integrated circuits need to be precisely welded and replaced in an anti-static environment; When repairing signal transmission lines, it is necessary to carefully investigate open circuits and short-circuit points, and perform welding or cable replacement. In the handling of mechanical structural faults, if the steel wire in the bending part breaks, it needs to be replaced with a new steel wire and the bending angle needs to be readjusted; The worn parts of the angle control device need to be replaced or repaired to ensure the accuracy of angle control; If the biopsy forceps are blocked, specialized dredging tools and cleaning solution are used for cleaning. ​

校准与测试​

Calibration and Testing

维修完成后，为确保内窥镜设备恢复到最佳性能状态，需进行严格的校准与测试。光学系统校准包括图像清晰度、色彩还原度、亮度均匀性等参数的调整；电子系统校准要对图像信号的增益、偏置等进行优化，保证图像质量稳定；机械结构校准则着重调整弯曲部的弯曲角度范围、活检钳道的开合力度等。在校准完成后，还需进行模拟临床使用的全面测试，包括将内窥镜插入模拟人体模型，检查图像质量、角度控制、活检钳道功能等是否正常，只有通过测试的设备才能重新投入临床使用。

After the repair is completed, strict calibration and testing are required to ensure that the endoscope equipment is restored to its optimal performance state. Optical system calibration includes adjusting parameters such as image clarity, color reproduction, and brightness uniformity; Electronic system calibration should optimize the gain and bias of image signals to ensure stable image quality; The mechanical structure calibration criteria focus on adjusting the bending angle range of the bending part and the opening and closing force of the biopsy forceps channel. After calibration is completed, comprehensive testing is required to simulate clinical use, including inserting an endoscope into a simulated human body model to check image quality, angle control, biopsy forceps function, etc. Only devices that pass the testing can be put back into clinical use.
