由于软性内窥镜具有良好的柔软性和方便的操作性能,在医学上得到了广泛的应用。那么您对软性内窥镜设备了解多少呢?
内窥镜维修公司的小编这就来简单解释下。
Because of its good flexibility and convenient operation, flexible endoscope has been widely used in medicine. How much do you know about soft endoscope equipment? Let's explain briefly.
软性内窥镜的特点:
Characteristics of soft endoscope:
柔软,可方便的进入人体复杂的内腔器官,既减少了病人的痛苦,又可到达硬性镜无法到达的地方。加上头部弯曲机构,可盲区。通过活检孔可采样和。
It is soft and can easily enter the complex internal organs of the human body, which can not only reduce the pain of patients, but also reach places that cannot be reached by rigid mirrors. With the head bending mechanism, the blind area can be eliminated. Sampling and treatment can be carried out through the biopsy hole.
拿软性内镜方法:
Methods of soft endoscopy:
带好手套,双手拿,手握把持部,手拿镜身,不要使先端部下垂,拿得要稳。
Wear gloves, hold it with both hands, hold the holding part, and hold the mirror body with hands. Do not let the tip droop, and hold it steadily.
纤维内镜构造:
Fiber endoscope structure:
先端部、弯曲部、插入部、操作部、导光软管、导光连接部、目镜。
Tip, bending part, insertion part, operation part, light guide hose, light guide connecting part, eyepiece.
先端部成硬性的小段,有直视式(前视式)、侧视式、斜视式。胃镜结肠镜等采用直视方式,十二指肠食道镜采用侧视方式。
There are rigid segments at the apex, including direct looking (forward looking), side looking and strabismus. Gastroscopy, colonoscopy, etc. adopt direct vision, and duodenoesophageal endoscopy adopts side view.
先端部上面有:物镜孔(导像束)、光孔(导光束)、气水孔(喷嘴)、活检孔。
There are objective lens hole (image guide beam), optical hole (light guide beam), air water hole (nozzle) and biopsy hole on the tip.
弯曲部采用四根钢丝牵引的方法,头部有四根钢丝连向控制部,扭动控制部的上下左右手轮,可分别拉动不同方向的钢丝,使弯曲头部向相应方向摆动。弯曲部内有导光束、导像束、各种管道以及牵引装置、弯曲管、弯曲橡皮。
The bending part adopts the method of four steel wires traction. There are four steel wires connected to the control part at the head. Twisting the upper, lower, left and right hand wheels of the control part can pull the steel wires in different directions respectively to make the bending head swing in the corresponding direction. There are guide beams, image guide beams, various pipes, traction devices, bending pipes and bending rubbers in the bending part.
软管部包括弯曲部和插入部,也称蛇管。装有导光束、导像束、水气管道、活检管道(兼吸引管道)、牵引钢丝,外包不锈钢带软管及金属网管,很外层为光滑的塑料套管。
The hose part includes a bending part and an inserting part, also known as a snake tube. It is equipped with guide beam, image beam, water and gas pipe, biopsy pipe (also suction pipe), traction steel wire, wrapped with stainless steel hose and metal network management, and the outer layer is smooth plastic sleeve.
传导图像的纤维束构成了纤维内镜的核心部分,它由数万根细的玻璃纤维组成,根据光学的全反射原理,所有玻璃纤维外面须再被覆一层折射率较低的膜,以保证所有内芯纤维传导的光线都能发生全反射。单根纤维的传递只能产生一个光点。
The fiber bundle conducting the image constitutes the core part of the fiber endoscope, which is composed of tens of thousands of thin glass fibers. According to the total reflection principle of optics, all glass fibers must be covered with a layer of film with low refractive index outside to ensure that the light transmitted by all inner core fibers can produce total reflection. The transmission of a single fiber can only produce one light spot.
要想看到图像,就须把大量的纤维集成束,要想把图像传递到另一端也成同样的图像,就须使每一根纤维在其两端所排列的位置相同,称为导像束。
If you want to see the image, you need to integrate a large number of fibers into bundles. If you want to transfer the image to the other end to form the same image, you need to make each fiber in the same position at both ends, which is called the image guide bundle.
一根导像束断开,成像就多-一个黑点。导光束则不需要所排的位置相同,断开很多根的话亮度明显减弱。
If one image guide beam is disconnected, there will be one more black spot. The guiding beam does not need to be arranged in the same position. If many beams are disconnected, the brightness will be significantly reduced.
