軟式內(nèi)窺鏡是一種集圖像傳感器、光學(xué)鏡頭、光源、機械系統(tǒng)等于一體的設(shè)備，可經(jīng)人體自然孔道或經(jīng)表層穿孔插入體內(nèi)，用于直接觀察人體體腔和內(nèi)臟器官的組織形態(tài)和病變部位，輔助疾病的診斷或治療，主要有胃腸鏡、氣管鏡等，是醫(yī)院易損且貴重歸Ⅲ類管理的醫(yī)療器械。下面內(nèi)窺鏡設(shè)備維修人員來講講軟式內(nèi)窺鏡的結(jié)構(gòu)成像與預(yù)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(jié)構(gòu)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(nèi)窺鏡的前端，包括導(dǎo)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(wǎng)、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(nèi)部包裹著導(dǎo)光束、導(dǎo)像束、送水/送氣管、鉗子管道和輪鼓鋼絲。操作部是醫(yī)生檢查、治療時手持操作的部分，主要包括角度控制轉(zhuǎn)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(tǒng)的部件，由導(dǎo)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(jiān)視器、附屬器械等設(shè)備組成一套完整的電子內(nèi)窺鏡系統(tǒng)。當(dāng)醫(yī)生為患者進行檢查時，鏡子通過人體自然腔道進入，由導(dǎo)光束將冷光源發(fā)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(xué)信息，先端的CCD或互補金屬氧化物半導(dǎo)體(ComplementaryMetal-Oxide-Semiconductor，CMOS)傳感器負責(zé)將光源信息轉(zhuǎn)換成電子信號，再通過信息線傳輸?shù)綀D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(yù)防性清點檢查

Regular preventive inventory inspection

預(yù)防性清點檢查是從內(nèi)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(fā)現(xiàn)內(nèi)窺鏡潛在風(fēng)險，防止故障擴大化，提高設(shè)備使用率，創(chuàng)造效益，避免損失。特別對于高精度、高效益、又昂貴的設(shè)備而言，定期預(yù)防性清點檢查可有效延長設(shè)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.

經(jīng)內(nèi)窺鏡廠家指導(dǎo)，小編在實踐工作經(jīng)驗中總結(jié)出一套內(nèi)鏡的清點檢查方法，主要由以下幾個步驟組成：①漏水檢測②外觀檢查③圖像檢查④功能檢查，詳見可以來我們網(wǎng)站http://yuxiaous.cn進行留言咨詢！
