内窥镜作为常用的医疗器械，也是一套精密贵重且容易损坏的仪器设备，因此内窥镜的维护保养及合理维修的技巧与策略就显得尤为重要，为了降低损坏率，也建议有专人负责术后清洗、保养、灭菌。下面内窥镜设备维修人员来讲讲内窥镜设计使用寿命与故障诊断。

As a commonly used medical device, endoscopes are also a set of precision, valuable, and easily damaged instruments and equipment. Therefore, the maintenance and reasonable repair techniques and strategies of endoscopes are particularly important. In order to reduce the damage rate, it is also recommended to have a dedicated person responsible for postoperative cleaning, maintenance, and sterilization. Below, the maintenance personnel of endoscope equipment will talk about the service life and fault diagnosis of endoscope design.

内窥镜设计使用寿命

Endoscope design service life

内窥镜在正常使用和规范的维护/灭菌前提下，有2个因素决定使用寿命：

Under the premise of normal use and standardized maintenance/sterilization, the lifespan of an endoscope is determined by two factors:

1、密封材料老化，导致内部光学部件进水甚至腐蚀，表现为图像模糊、水雾、斑点。

1. The aging of sealing materials leads to water ingress and even corrosion of internal optical components, manifested as blurred images, water mist, and spots.

2、光纤损坏超过30%，表现为亮度逐渐减弱，颜色变黄。

2. The damage to the optical fiber exceeds 30%, manifested as a gradual decrease in brightness and a yellowing of color.

内窥镜故障的类型

Types of endoscopic malfunctions

故障类型大致分为：①自然老化或人为故障；②机械或电子故障；③静态或动态故障；④设备本身或周边环境引起的故障；⑤还有一些是形式多种、故障交叉同时发生的故障。

The types of faults can be roughly divided into: ① natural aging or artificial faults; ② Mechanical or electronic faults; ③ Static or dynamic faults; ④ Faults caused by the equipment itself or surrounding environment; ⑤ There are also faults that occur in multiple forms and cross over simultaneously.

造成内窥镜故障发生的因素

Factors that cause endoscopic malfunctions

可能归纳为三个主要因素：①医护人员操作习惯，清洗消毒人员的习惯，病人的配合程度等；②设备本身的特性，清洗消毒、配合诊治等相关设备情况；③使用环境、保管环境，还有管理制度环境。

It may be summarized into three main factors: ① the operating habits of medical staff, the habits of cleaning and disinfecting personnel, and the degree of patient cooperation; ② The characteristics of the equipment itself, cleaning, disinfection, and coordination with diagnosis and treatment related equipment; ③ The usage environment, storage environment, and management system environment.

内窥镜故障判断的方法

Method for diagnosing endoscopic malfunctions

故障判断的方法包括：①排除法：常规使用的基本方法，对工作原理要非常了解；

The methods for fault diagnosis include: ① troubleshooting: basic methods for routine use, and a good understanding of the working principle;

②跟台发现法：针对一些人为因素导致的故障使用中才发现；

② Follow the platform discovery method: only discover faults caused by human factors during use;

③点检检测法：针对未发现故障，排查潜在故障避免故障扩大及延变；

③ Spot check detection method: for undetected faults, identify potential faults to avoid fault expansion and extension;

④故障推理法：针对发现了问题，故障如何产生的；

④ Fault inference method: targeting the problem discovered and how the fault was generated;

⑤经验判断法：根据多年的工作经验积累进行总结及分析。

⑤ Empirical judgment method: Summarize and analyze based on years of work experience accumulation.
