在现代医疗领域，内窥镜设备宛如医生的 “第三只眼”，凭借其能够深入人体内部、清晰呈现器官组织状况的卓越能力，成为疾病诊断与治疗过程中不可或缺的关键工具。无论是消化道疾病的排查、呼吸道病症的诊断，还是各类微创手术的实施，内窥镜设备都发挥着无可替代的作用。然而，如同任何精密仪器一样，内窥镜设备在长期频繁使用过程中，难免会出现各种故障，此时，专业、高效的维修服务便成为保障其持续精准运行，维系医疗工作正常开展的关键防线。​

In the modern medical field, endoscopic equipment is like a doctor's "third eye". With its excellent ability to penetrate deep into the human body and clearly present the condition of organs and tissues, it has become an indispensable key tool in the process of disease diagnosis and treatment. Endoscopic equipment plays an irreplaceable role in the screening of digestive diseases, diagnosis of respiratory diseases, and implementation of various minimally invasive surgeries. However, like any precision instrument, endoscopic equipment is inevitably prone to various malfunctions during long-term and frequent use. At this time, professional and efficient maintenance services become the key defense line to ensure its continuous and accurate operation and maintain the normal development of medical work. ​

内窥镜设备的重要地位与故障频发挑战​

The Importance of Endoscopic Equipment and the Challenges of Frequent Malfunctions

内窥镜设备以其直观、准确的检查优势，极大地提高了疾病诊断的准确性和效率。在消化内科，胃肠镜能够直接观察食管、胃、肠道等部位的黏膜病变，帮助医生及时发现胃溃疡、息肉、肿瘤等疾病，为后续治疗提供重要依据。在呼吸内科，支气管镜可深入气管和支气管，对肺部疾病进行精准诊断，在肺癌早期筛查中发挥着关键作用。在外科手术领域，腹腔镜、关节镜等内窥镜设备使微创手术得以广泛开展，降低了手术创伤，缩短了患者康复时间。​

Endoscopic equipment, with its intuitive and accurate inspection advantages, greatly improves the accuracy and efficiency of disease diagnosis. In gastroenterology, gastroscopy can directly observe mucosal lesions in the esophagus, stomach, intestines, and other areas, helping doctors detect gastric ulcers, polyps, tumors, and other diseases in a timely manner, providing important evidence for subsequent treatment. In respiratory medicine, bronchoscopy can penetrate deep into the trachea and bronchi to accurately diagnose lung diseases, playing a key role in early screening of lung cancer. In the field of surgical procedures, endoscopic devices such as laparoscopy and arthroscopy enable minimally invasive surgery to be widely performed, reducing surgical trauma and shortening patient recovery time. ​

但内窥镜设备的精密性和使用环境的特殊性，使其面临较高的故障风险。一方面，设备需频繁进入人体内部，在复杂的生理环境中工作，容易受到胃酸、胆汁、血液等腐蚀性物质的侵蚀，导致镜体表面磨损、管道堵塞、电子元件损坏等问题。另一方面，在日常使用过程中，由于操作不当，如过度弯曲镜身、碰撞硬性物体等，也可能引发镜体折断、图像模糊、光源异常等故障。据不完全统计，约 70% 的内窥镜设备在使用 3 - 5 年后，会因各种原因出现不同程度的故障，严重影响医疗工作的正常进行。

However, the precision of endoscopic equipment and the particularity of its usage environment pose a high risk of malfunction. On the one hand, the equipment needs to frequently enter the human body and work in a complex physiological environment, which is easily corroded by corrosive substances such as stomach acid, bile, and blood, leading to problems such as surface wear of the mirror, pipeline blockage, and damage to electronic components. On the other hand, in daily use, improper operation such as excessive bending of the mirror body, collision with hard objects, etc. may also cause faults such as mirror breakage, blurred images, and abnormal light sources. According to incomplete statistics, about 70% of endoscopic equipment will experience varying degrees of malfunctions due to various reasons after 3-5 years of use, seriously affecting the normal operation of medical work.

常见故障类型与维修要点解析​

Analysis of Common Fault Types and Maintenance Points

光学系统故障​

Optical system malfunction

内窥镜的光学系统负责将人体内部的图像清晰地传输至医生视野，一旦出现故障，将直接影响诊断和治疗效果。常见的光学系统故障包括图像模糊、有黑斑或条纹、亮度不足等。图像模糊可能是由于物镜表面沾染污渍、光学镜片磨损或位移导致。维修时，需专业维修人员使用高精度的清洁工具和设备，对物镜进行仔细清洁，若镜片磨损或位移，则需借助精密仪器进行校准和更换。对于亮度不足的问题，可能是光源灯泡老化、光纤断裂或导光系统故障。维修人员需排查光源系统各部件，更换老化灯泡，修复或更换断裂的光纤，确保导光系统正常工作。​

The optical system of an endoscope is responsible for transmitting the internal images of the human body clearly to the doctor's field of view. Once a malfunction occurs, it will directly affect the diagnosis and treatment effectiveness. Common optical system failures include blurry images, black spots or stripes, insufficient brightness, etc. Image blur may be caused by stains on the surface of the objective lens, wear or displacement of the optical lens. When repairing, professional maintenance personnel need to use high-precision cleaning tools and equipment to carefully clean the objective lens. If the lens is worn or displaced, precision instruments need to be used for calibration and replacement. For the issue of insufficient brightness, it may be due to aging of the light source bulb, fiber breakage, or malfunction of the light guiding system. Maintenance personnel need to inspect all components of the light source system, replace aging bulbs, repair or replace broken optical fibers, and ensure the normal operation of the light guiding system. ​

电子系统故障​

Electronic system malfunction

随着内窥镜技术的不断发展，电子系统在设备中的作用愈发重要。电子系统故障可能导致图像信号传输异常、设备死机、无法开机等问题。例如，摄像头芯片损坏会使图像出现噪点、色彩失真或无图像输出。维修此类故障，需要维修人员具备扎实的电子电路知识，能够使用专业的电子检测设备，如示波器、逻辑分析仪等，对电路板上的芯片、电容、电阻等元件进行检测和更换。同时，对于软件系统出现的故障，如设备驱动程序损坏、操作系统崩溃等，维修人员需熟练掌握设备的软件安装和调试方法，进行相应的修复和升级。

With the continuous development of endoscopic technology, the role of electronic systems in devices has become increasingly important. Electronic system failures may cause issues such as abnormal image signal transmission, device crashes, and inability to power on. For example, damaged camera chips can cause noise, color distortion, or no image output in the image. To repair such faults, maintenance personnel need to have solid knowledge of electronic circuits and be able to use professional electronic testing equipment such as oscilloscopes, logic analyzers, etc. to detect and replace components such as chips, capacitors, resistors, etc. on the circuit board. At the same time, for software system failures such as device driver program damage, operating system crashes, etc., maintenance personnel need to be proficient in the software installation and debugging methods of the device, and carry out corresponding repairs and upgrades.
