纖維內窺鏡工作原理介紹

來源://versaemergefan.com/ 發布時間:2023-03-20 瀏覽量:0

纖維內窺鏡與傳統純光學鏡片構成的內窺鏡或電子內窺鏡的大區別在于傳像組采用了傳像光纖,該傳像光纖由多束導光纖維按照坐標對位原則面陣排列,每一根導光纖維作為面陣上一個像素在傳像光纖兩端的坐標位置一一對應。物鏡將物體直接聚焦并成像于光纖面陣上,光纖面陣上的每一像素(每一根導光纖維)分別接收對應位置像的光能,并將該光能傳輸傳像光纖的另一端發出,光纖面陣上的所有像素在像方端輸出的全部光能重組了物鏡的聚焦像,即達到了光纖傳像目的。

The major difference between fiber endoscopes and traditional pure optical endoscopes or electronic endoscopes is that the image transmission group uses image transmission optical fibers, which are arranged in an array of multiple light guiding fibers according to the principle of coordinate alignment. Each light guiding fiber serves as a pixel on the array and corresponds one-to-one with the coordinate positions at both ends of the image transmission fiber. The objective lens focuses the object directly and images it on a fiber optic array. Each pixel (each guiding fiber) on the fiber optic array receives the corresponding position image's light energy and transmits it to the other end of the image transmission fiber for emission. All the light energy output by all pixels on the fiber optic array at the image end recombines the focus image of the objective lens, achieving the goal of fiber optic image transmission.

纖維內窺鏡有效應用的關鍵性能是成像水平,除要求物鏡有大視角、小畸變、高相對孔徑和景深外,傳像光纖質量是纖維內窺鏡成像質量和水平的主要貢獻,其中傳像光纖的像素數是限制纖維內窺鏡分辨極限的關鍵因素(對給定視場而言)。高像素數傳像光纖的制作,涉及單光纖芯直徑制造能力和成型技術。這類制造工藝有:熱溶法等,排列工藝有:單層合片法等,目前傳像光纖小芯徑不足5微米。其他如單光纖一致性質量、面形處理等也限制了傳像光纖的質量。

The key performance for the effective application of fiber endoscopes is the imaging level. In addition to requiring the objective lens to have a large viewing angle, small distortion, high relative aperture, and depth of field, the quality of the image transmission fiber is the main contribution to the imaging quality and level of fiber endoscopes. The number of pixels in the image transmission fiber is a key factor limiting the resolution limit of fiber endoscopes (for a given field of view). The production of high resolution digital image transmission optical fibers involves the manufacturing capability and forming technology of a single fiber core diameter. This type of manufacturing process includes hot melt method, and arrangement process includes single-layer lamination method. Currently, the small core diameter of image transmission optical fibers is less than 5 microns. Other factors such as single fiber consistency quality and surface treatment also limit the quality of image transmission fibers.

纖維內窺鏡是供人體內腔檢查和手術時用的醫用光學器械。它利用人體自然腔道或切口導入人體,對預期區域或部位進行照明并于體外成像以供觀察和診查,結合手術器械可進行諸如:組織取樣(活檢)、切割、粉碎、消融、止血、凝固等臨床手術。

Fiber endoscope is a medical optical instrument used for examination and surgery of the human body's internal cavity. It uses natural channels or incisions to introduce the human body, illuminating the expected area or area, and imaging it in vitro for observation and diagnosis. Combined with surgical instruments, it can perform clinical surgeries such as tissue sampling (biopsy), cutting, crushing, ablation, hemostasis, coagulation, etc.

應用特點:可借助于手術器械、高頻電刀、激光等進行活檢并實施腔內手術;纖維內窺鏡為柔性內窺鏡,其插入部及頭部均能彎曲。可通過攝錄電視系統,供觀察、研討和教學之用,也可用照相予以記錄

Application features: Biopsy and intracavitary surgery can be performed using surgical instruments, high-frequency electric knives, lasers, etc; Fiber endoscopes are flexible endoscopes, and their insertion and head can be bent. It can be used for observation, discussion, and teaching through a video recording system, and can also be recorded through photography
