软式内窥镜是一种集图像传感器、光学镜头、光源、机械系统等于一体的设备，可经人体自然孔道或经表层穿孔插入体内，用于直接观察人体体腔和内脏器官的组织形态和病变部位，辅助疾病的诊断或，主要有胃肠镜、气管镜等，是医院易损且贵重归Ⅲ类管理的医疗器械。下面内窥镜设备维修人员来讲讲软式内窥镜的结构成像与预防性清点检查事项吧。

A flexible endoscope is a device that integrates image sensors, optical lenses, light sources, and mechanical systems. It can be inserted into the body through natural channels or through surface perforations. It is used to directly observe the tissue morphology and lesion sites of the human body cavity and internal organs, and assist in the diagnosis or treatment of diseases. It mainly includes gastroscopy, tracheoscopy, etc. It is a vulnerable and expensive medical device classified as Class III management in hospitals. Let's talk about the structural imaging and preventive inventory inspection of flexible endoscopes by the maintenance personnel of endoscope equipment below.

结构与成像原理

Structure and Imaging Principles

软镜由先端弯曲部、插入部、钳子管道口、操作部、电气连接部等组成。先端弯曲部是内窥镜的前端，包括导光束、物镜、电荷耦合器件（chargecoupleddevice，CCD）、钳子道口、送水送气管道、弯曲橡皮、金属编织网、弯曲骨架等。

The soft mirror is composed of a tip bending part, an insertion part, a pliers pipe mouth, an operation part, an electrical connection part, etc. The bending part at the front end is the front end of the endoscope, including the guiding beam, objective lens, charge coupled device (CCD), clamp passage, water and gas supply pipeline, bending rubber, metal woven mesh, bending skeleton, etc.

插入部外面是带刻度的外皮，内部包裹着导光束、导像束、送水/送气管、钳子管道和轮鼓钢丝。操作部是医生检查、时手持操作的部分，主要包括角度控制转子、卡锁、功能按钮、吸引活塞、送水/送气活塞、钳子管道入口等。电气连接部是软镜连接冷光源和图像处理系统的部件，由导光杆、送水/送气接头、吸引接口等组成。

The outer part of the insertion part is a graduated outer skin, and the inner part is wrapped with a guide beam, an image guide beam, a water/air supply pipe, a pliers pipe, and a drum steel wire. The operation department is a handheld part operated by doctors during examination and treatment, mainly including angle control rotors, locks, function buttons, suction pistons, water/air supply pistons, pliers pipeline entrances, etc. The electrical connection part is a component that connects a cold light source and an image processing system with a soft mirror, consisting of a light guide rod, a water/air supply joint, and an attraction interface.

软镜、冷光源、图像处理器、监视器、附属器械等设备组成一套完整的电子内窥镜系统。当医生为患者进行检查时，镜子通过人体自然腔道进入，由导光束将冷光源发出的光照射到需要检查的部位上，然后由先端镜头记录下光学信息，先端的CCD或互补金属氧化物半导体(ComplementaryMetal-Oxide-Semiconductor，CMOS)传感器负责将光源信息转换成电子信号，再通过信息线传输到图像处理器进行处理后在显示器成像。

A complete electronic endoscope system is composed of soft mirrors, cold light sources, image processors, monitors, accessory devices, and other equipment. When a doctor examines a patient, a mirror enters through the natural cavity of the human body, and the light emitted by the cold light source is illuminated by a guiding beam to the area to be examined. Then, the optical information is recorded by the front-end lens, and the front-end CCD or Complementary Metal Oxide Semiconductor (CMOS) sensor is responsible for converting the light source information into an electronic signal, Then, it is transmitted to the image processor through an information cable for processing before being imaged on the display.

定期预防性清点检查

Regular preventive inventory inspection

预防性清点检查是从内窥镜的外观、功能、图像等方面进行一系列详细检测，进而及时发现内窥镜潜在风险，防止故障扩大化，提高设备使用率，创造效益，避免损失。特别对于高精度、益、又昂贵的设备而言，定期预防性清点检查可有效延长设备使用寿命。

Preventive inventory inspection is a series of detailed inspections conducted from the appearance, function, image, and other aspects of the endoscope, in order to timely identify potential risks of the endoscope, prevent the expansion of faults, improve equipment utilization, create benefits, and avoid losses. Especially for high-precision, cost-effective, and expensive equipment, regular preventive inventory checks can effectively extend the service life of the equipment.
