在内窥镜的微观探索世界里，纤细的光纤如同“视觉神经”，承担着传输图像、照亮黑暗角落的重任。一旦这根 “神经” 受损，内窥镜就会 “视力模糊” 甚至 “失明”，影响精密检测与诊断工作。而光纤修复技术，就像一位技艺高超的 “眼科医生”，为受损的内窥镜光纤实施神奇 “手术”，助其重新 “点亮视界”，继续在医疗、工业检测等领域发挥重要作用。

　　In the microscopic exploration world of endoscopes, slender optical fibers are like "visual nerves", responsible for transmitting images and illuminating dark corners. Once this' nerve 'is damaged, the endoscope will have' blurred vision 'or even' blindness', affecting precision detection and diagnosis work. Fiber optic repair technology, like a highly skilled "ophthalmologist", performs miraculous "surgery" on damaged endoscope fibers, helping them to "brighten up their vision" and continue to play an important role in medical, industrial testing, and other fields.

　　内窥镜的光纤之所以需要修复，是因为在使用过程中，它面临着诸多挑战。在医疗场景中，内窥镜需要深入人体复杂的腔体，弯曲、扭转、碰撞等操作都可能导致光纤断裂、磨损；在工业检测时，高温、腐蚀性环境或机械外力，也容易损伤光纤的结构，破坏其光信号传输功能。而光纤修复技术的核心，在于精准处理受损部位，恢复光信号的稳定传输。

　　The reason why the optical fiber of the endoscope needs to be repaired is that it faces many challenges during use. In medical settings, endoscopes need to penetrate complex cavities in the human body, and operations such as bending, twisting, and collision may cause fiber breakage and wear; In industrial testing, high temperatures, corrosive environments, or mechanical external forces can also easily damage the structure of optical fibers and disrupt their optical signal transmission function. The core of fiber optic repair technology lies in accurately handling damaged areas and restoring stable transmission of optical signals.

　　光纤修复的第一步是定位受损点。这就好比医生诊断病情，需要先找到 “病灶”。借助高倍显微镜和专业的检测设备，技术人员能够清晰观察到光纤的微观结构，准确判断断裂、磨损的具体位置。哪怕是微米级的损伤，也逃不过这些精密仪器的 “眼睛”。确定受损点后，就要进行清洁工作，使用专用的清洁剂和擦拭工具，小心去除光纤表面的污渍、杂质和氧化物，避免这些 “障碍物” 影响修复效果，为后续操作创造良好条件。

　　The first step in fiber optic repair is to locate the damaged point. This is like a doctor diagnosing a disease, they need to first find the 'lesion'. With the help of high-power microscopes and professional testing equipment, technicians can clearly observe the microstructure of optical fibers and accurately determine the specific location of fractures and wear. Even micrometer level damage cannot escape the "eyes" of these precision instruments. After identifying the damaged point, cleaning work should be carried out using specialized cleaning agents and wiping tools to carefully remove stains, impurities, and oxides on the surface of the optical fiber, avoiding these "obstacles" from affecting the repair effect and creating good conditions for subsequent operations.

　　接下来是关键的修复环节，熔接技术是常用手段。这一过程类似于为光纤 “接骨”，将两段受损光纤的端面放置在熔接机的夹具上，通过放电产生高温，使光纤端面瞬间熔化，再精确控制熔接参数，让两段光纤融合在一起。熔接机就像一位 “微型工匠”，以极高的精度调整光纤的位置和角度，确保熔接后的光纤轴线对齐，最大限度减少光信号在连接处的损耗。为了增强熔接部位的强度和稳定性，还会在熔接点套上保护套管，并进行加热固化处理，给 “接骨处” 打上坚固的 “石膏”。

　　The next step is the crucial repair process, and welding technology is a commonly used method. This process is similar to "joining" optical fibers by placing the end faces of two damaged fibers on the fixture of a fusion splicer, generating high temperatures through discharge to instantly melt the fiber end faces, and then precisely controlling the fusion parameters to fuse the two fibers together. The fusion splicer is like a "micro craftsman", adjusting the position and angle of the optical fiber with extremely high precision, ensuring that the axis of the fused optical fiber is aligned, and minimizing the loss of optical signals at the connection. In order to enhance the strength and stability of the fusion joint, a protective sleeve will be placed over the fusion joint and subjected to heating and solidification treatment, and a sturdy "plaster" will be applied to the "joint".

　　除了熔接，对于一些轻微的损伤，还可以采用机械连接的修复方式。通过特殊设计的连接器，将两段光纤紧密对接，这种方法操作相对简便，适合应急修复或对精度要求不是极高的场景。但机械连接的光信号损耗通常比熔接稍大，所以在对图像质量要求严格的内窥镜修复中，熔接技术更为常用。

　　In addition to welding, mechanical connections can also be used to repair minor damages. By using specially designed connectors to tightly connect two sections of optical fibers, this method is relatively easy to operate and suitable for emergency repairs or scenarios where precision requirements are not extremely high. However, the optical signal loss of mechanical connections is usually slightly greater than that of fusion splicing, so fusion splicing technology is more commonly used in endoscopic repairs that require strict image quality.

　　光纤修复技术给内窥镜带来的优势显而易见。它能够快速、高效地恢复内窥镜的 “视力”，让其重新投入使用，减少设备停机时间，无论是医疗手术的紧急需求，还是工业检测的进度要求，都能得到及时满足。而且，修复后的光纤能够保持较高的光传输质量，确保内窥镜传回的图像清晰、稳定，为医疗诊断和工业检测提供可靠依据。从成本角度看，相比更换整根光纤或内窥镜设备，修复技术大大降低了维修成本，提高了设备的使用寿命和利用率，实现了资源的高效利用。

　　The advantages brought by fiber optic repair technology to endoscopes are obvious. It can quickly and efficiently restore the "vision" of endoscopes, allowing them to be put back into use and reducing equipment downtime. Whether it is urgent needs for medical surgery or progress requirements for industrial testing, they can be met in a timely manner. Moreover, the repaired optical fiber can maintain high optical transmission quality, ensuring clear and stable images transmitted back by the endoscope, providing reliable basis for medical diagnosis and industrial testing. From a cost perspective, compared to replacing the entire fiber optic or endoscopic equipment, repair technology greatly reduces maintenance costs, improves equipment lifespan and utilization, and achieves efficient resource utilization.

　　光纤修复技术就像一场为内窥镜量身定制的神奇 “手术”，从精准诊断到精心修复，每一个步骤都充满智慧与巧思。它让受损的内窥镜重获 “光明”，继续在各个领域发挥着不可替代的作用，成为保障微观探索工作顺利进行的重要力量。

　　Fiber optic repair technology is like a magical "surgery" tailored for endoscopes, from precise diagnosis to meticulous repair, every step is full of wisdom and ingenuity. It allows damaged endoscopes to regain their "brightness" and continue to play an irreplaceable role in various fields, becoming an important force in ensuring the smooth progress of micro exploration work.
