軟式內窺鏡是一種集圖像傳感器、光學鏡頭、光源、機械系統等于一體的設備,可經人體自然孔道或經表層穿孔插入體內,用于直接觀察人體體腔和內臟器官的組織形態和病變部位,輔助疾病的診斷或,主要有胃腸鏡、氣管鏡等,是醫院易損且貴重歸Ⅲ類管理的醫療器械。下面
內窺鏡設備維修人員來講講軟式內窺鏡的結構成像與預防性清點檢查事項吧。
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.
結構與成像原理
Structure and Imaging Principles
軟鏡由先端彎曲部、插入部、鉗子管道口、操作部、電氣連接部等組成。先端彎曲部是內窺鏡的前端,包括導光束、物鏡、電荷耦合器件(chargecoupleddevice,CCD)、鉗子道口、送水送氣管道、彎曲橡皮、金屬編織網、彎曲骨架等。
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.
插入部外面是帶刻度的外皮,內部包裹著導光束、導像束、送水/送氣管、鉗子管道和輪鼓鋼絲。操作部是醫生檢查、時手持操作的部分,主要包括角度控制轉子、卡鎖、功能按鈕、吸引活塞、送水/送氣活塞、鉗子管道入口等。電氣連接部是軟鏡連接冷光源和圖像處理系統的部件,由導光桿、送水/送氣接頭、吸引接口等組成。
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.
軟鏡、冷光源、圖像處理器、監視器、附屬器械等設備組成一套完整的電子內窺鏡系統。當醫生為患者進行檢查時,鏡子通過人體自然腔道進入,由導光束將冷光源發出的光照射到需要檢查的部位上,然后由先端鏡頭記錄下光學信息,先端的CCD或互補金屬氧化物半導體(ComplementaryMetal-Oxide-Semiconductor,CMOS)傳感器負責將光源信息轉換成電子信號,再通過信息線傳輸到圖像處理器進行處理后在顯示器成像。
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.
定期預防性清點檢查
Regular preventive inventory inspection
預防性清點檢查是從內窺鏡的外觀、功能、圖像等方面進行一系列詳細檢測,進而及時發現內窺鏡潛在風險,防止故障擴大化,提高設備使用率,創造效益,避免損失。特別對于高精度、益、又昂貴的設備而言,定期預防性清點檢查可有效延長設備使用壽命。
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.
Under the guidance of the endoscope manufacturer, the editor has summarized a set of endoscopic inventory inspection methods based on practical work experience, which mainly consists of the following steps: ① leak detection; ② appearance inspection; ③ image inspection; ④ functional inspection.
