內(nèi)窺鏡攝像系統(tǒng)及特點有哪些?

醫(yī)用內(nèi)窺鏡是集傳統(tǒng)光學(xué)、人體工程學(xué)、精密機械、現(xiàn)代電子、數(shù)學(xué)、軟件等于一體的檢測儀器,主要由圖像傳感器、光學(xué)鏡頭、光源照明、機械裝置等部件構(gòu)成,它可以通過人體的自然腔道或者細(xì)小手術(shù)切口進(jìn)入體內(nèi),利用內(nèi)窺鏡可以看到X射線不能顯示的病變,醫(yī)生可據(jù)此制定出的方案。據(jù)行行查數(shù)據(jù)顯示,醫(yī)用內(nèi)窺鏡主要分為以下兩大類:
Medical endoscope is a testing instrument integrating traditional optics, ergonomics, precision machinery, modern electronics, mathematics and software. It is mainly composed of image sensors, optical lenses, light source lighting, mechanical devices and other components. It can enter the body through the natural cavity or small Surgical incision of the human body. With the endoscope, you can see the lesions that cannot be displayed by X-ray, and doctors can formulate the best treatment plan accordingly. According to the survey data, medical endoscopes are mainly divided into the following two categories:
硬管式內(nèi)窺鏡:不可彎曲,經(jīng)過外科切口進(jìn)入人體無菌組織、器官、無菌腔室,主要包括腹腔鏡、胸腔鏡、關(guān)節(jié)鏡等,硬管式內(nèi)窺鏡可分為白光硬鏡和熒光硬鏡。
Hard tube endoscope: It can not be bent and can enter into sterile tissues, organs and sterile chambers of human body through surgical incision, mainly including laparoscope, Thoracoscopy, Arthroscopy, etc. Hard tube endoscope can be divided into white light hard endoscope and fluorescent hard endoscope.
內(nèi)窺鏡設(shè)備維修
軟管式內(nèi)窺鏡:可以自由彎曲,通過人體自然腔道進(jìn)入體內(nèi),鏡體較長同時具有一定柔性,光電信號傳輸距離較遠(yuǎn),鏡體插入部直徑較小且功能集成復(fù)雜,對設(shè)計工藝及制造技術(shù)的要求更高,具有較高的技術(shù)壁壘,主要包括胃鏡、腸鏡、支氣管鏡等。
Flexible tube endoscope: It can freely bend and enter the body through the natural lumen of the human body. The mirror body is long and has a certain degree of flexibility, and the photoelectric signal transmission distance is long. The diameter of the insertion part of the mirror body is small and the functional integration is complex. It has higher requirements for design process and manufacturing technology, and has high technical barriers, mainly including gastroscopy, colonoscopy, bronchoscopy, etc.
醫(yī)用內(nèi)窺鏡主要由三大系統(tǒng)組成,分別為窺鏡系統(tǒng)、圖像顯示系統(tǒng)、照明系統(tǒng)。以目前較為常用的電子內(nèi)窺鏡為例,鏡體伸入患者體內(nèi),鏡體內(nèi)部并列多個管道,包括照明光纖、傳像光纖、傳氣通道、傳水通道、器械通道等,行行查數(shù)據(jù)顯示,內(nèi)窺鏡精密度極高,需要多個領(lǐng)域相互配合。
Medical endoscopes are mainly composed of three major systems, namely the endoscope system, image display system, and lighting system. Taking the commonly used electronic endoscope as an example, the body of the endoscope extends into the patient's body, and multiple pipelines are parallel inside the mirror body, including lighting fiber, image fiber, gas channel, water channel, instrument channel, etc. The inspection data shows that the precision of the endoscope is extremely high, requiring cooperation from multiple professional fields.
窺鏡系統(tǒng):主要包括手柄和鏡體。鏡體主要由物鏡、傳像元件、目鏡、照明元件及輔助元件等組成。
Camera system: mainly including handle and mirror body. The mirror body is mainly composed of objective lenses, image transmission components, eyepieces, lighting components, and auxiliary components.
圖像顯示系統(tǒng):早期內(nèi)窺鏡或硬管式內(nèi)窺鏡采用直視,而現(xiàn)在的電子內(nèi)窺鏡通常由CCD/CMOS光電傳感器、顯示器、計算機和圖像處理器組成。
Image display system: Early endoscopes or rigid tube endoscopes used direct vision, while modern electronic endoscopes typically consist of CCD/CMOS photoelectric sensors, displays, computers, and image processors.
