内窥镜是比较精密而又价格昂贵的医疗设备。特别是纤维内镜，由于它的导像束采用了非常“脆弱”和十分“娇气”的玻璃纤维束，而表面和内部各种管道采用了塑料制品，并且与金属连接是用黏合剂固定的，机械传动部分又采用细钢丝牵引的，这些材料决定了内镜具有比较短的正常使用寿命。一般临床只能用千余例，就要进行检修，甚至报废。
Endoscope is a more precise and expensive medical equipment. Especially for fiber endoscope, because its image guide bundle adopts very "fragile" and "delicate" glass fiber bundle, while various pipes on the surface and inside are made of plastic products, and the connection with metal is fixed with adhesive, and the mechanical transmission part is led by fine steel wire, these materials determine that the endoscope has a relatively short normal service life. Generally, more than a thousand cases can only be used in clinic, which will be overhauled or even scrapped.
维修的分类：
Classification of maintenance:
（1）预防性维修，指在内镜发生故障之前，使其保持在规定状态所进行的全部活动。包括调整、润滑、定期检查、定期更换等。
(1) Preventive maintenance refers to all activities to keep the endoscope in the specified state before it fails. Including adjustment, lubrication, regular inspection, regular replacement, etc.
（2）修复性维修，也叫排除故障维修或者故障维修，是内镜发生故障后，使其恢复到规定状态所进行的全部活动。包括故障定位、隔离、分解、更换、安装、调整、检验等。

(2) Restorative maintenance, also known as troubleshooting maintenance or fault maintenance, is all activities carried out to restore the endoscope to the specified state after failure. Including fault location, isolation, disassembly, replacement, installation, adjustment, inspection, etc.
（3）应急性维修，是指内镜正在临床使用中，突然发生故障的紧急修理。主要表现是随机故障、操作差错或者意外事故造成的损坏等。
(3) Emergency maintenance refers to the emergency repair of sudden failure of endoscopy in clinical use. The main manifestations are damage caused by random faults, operation errors or accidents.
（4）改进性维修，利用完成维修任务的时机，对内镜的技术指标或性能或使之适用某一特殊用途，改进性的维修实质是修改内镜的部分设计。
(4) Improved maintenance refers to the use of the opportunity to complete the maintenance task to improve the technical index or performance of the endoscope or make it suitable for a special purpose. The essence of improved maintenance is to modify part of the design of the endoscope.
（5）按维修性质、范围、深度分为小修、中修、大修。小修是指轻度损坏的维修，属于临床运行性修理。中修是指对主要系统、部件进行恢复性能的修理，属于平衡性修理。大修是指对内镜性能全面恢复的修理，属于全面恢复性修理。
(5) According to the nature, scope and depth of maintenance, it is divided into minor repair, medium repair and overhaul. Minor repair refers to the repair of slight damage, which belongs to clinical operation repair. Intermediate repair refers to the repair to restore the performance of main systems and components, which belongs to balanced repair. Overhaul refers to the repair of comprehensive restoration of endoscopic performance, which belongs to comprehensive restorative repair.
（6）按内镜的结构故障维修又分为光学系统维修、机械系统维修、电气控制系统维修。又可称为光路、水路、气路、电路、油路全面维修。
(6) According to the structure of endoscope, fault maintenance is divided into optical system maintenance, mechanical system maintenance and electrical control system maintenance. It can also be called comprehensive maintenance of light path, water path, gas path, circuit and oil path.
