内窥镜的出现，不仅延展了手术医生的眼睛，而且其分辨率、清晰度都大大增加。今天内窥镜设备维修人员就带大家一起来学习一下内窥镜的基本知识。

The appearance of endoscope not only extends the surgeon's eyes, but also greatly increases its resolution and clarity. Today, the endoscope equipment maintenance personnel will take you to learn the basic knowledge of the endoscope.

内窥镜是一种常用的医疗器械.由导光束结构及一组镜头组成。经人体的天然孔道或经小切口进入人体内，通过设备外部成像用于人体器官或组织的检查及手术治疗。而临床上常用的腹腔镜属于硬式内窥镜，是指利用一系列光学柱状晶体透镜将影像传送到接目镜，并通过连接独立摄像头进行成像的设备。

Endoscope is a commonly used medical instrument It consists of a guide beam structure and a group of lenses. It enters the human body through natural channels or small incisions, and is used for examination and surgical treatment of human organs or tissues through external imaging of equipment. The laparoscope commonly used in clinical practice belongs to hard endoscope, which refers to the equipment that transmits images to the eyepiece by using a series of optical cylindrical lens, and images through connecting independent cameras.

内窥镜的分类

Classification of endoscopes

按成像原理分：光学镜（柱状透镜）、纤维镜、电子镜

According to imaging principle: optical lens (cylindrical lens), fiber lens, electronic lens

按功能分：腹腔镜、膀胱镜、关节镜、胃肠镜、胆道镜等

By function: laparoscope, cystoscope, arthroscope, gastroenteroscope, choledochoscope, etc

按形态分：硬式内窥镜、软式内窥镜

According to morphology: hard endoscope, soft endoscope

按用途分：腹腔镜、电切镜、鼻窦镜等

Classified by purpose: laparoscope, resectoscope, sinusoscope, etc

按角度分：对于角度的描述多数指的是硬式内窥镜，根据检查部位的要求，提供不同的视野角度，可分为0°、12°、30°、70°等，应用于不同的手术科室。

Classification by angle: most of the descriptions of angles refer to rigid endoscopes. According to the requirements of the inspection site, different visual field angles can be provided, which can be divided into 0 °, 12 °, 30 °, 70 °, etc., and applied to different operating departments.

内窥镜有多种角度可选，我们可以通过不同的颜色标识就可以知道镜子的角度，具体如下：

The endoscope has a variety of angles to choose from. We can know the angle of the mirror through different color marks, as follows:

看了这么多角度的镜头，是不是会有一种想法，能不能把各种角度的镜头合为一体呢？近年来，就有了一种新镜头—变色龙镜（EndoCameleon），它在0°-120°之间可以调整视野角度，通过旋转调节镜头前端的物镜，实现视向角度无缝切换，与现有的10mm腹腔镜镜头相比，大大扩展了应用范围!

After seeing so many angles of lens, will you have an idea that you can integrate all angles of lens? In recent years, there has been a new lens - EndoCameleon, which can adjust the field of vision angle between 0 ° - 120 °. By rotating the objective lens at the front of the lens, the viewing angle can be switched seamlessly. Compared with the existing 10mm laparoscopic lens, it has greatly expanded the application range!

要想用好内窥镜就要对其原理有深入的了解，内窥镜延展了外科视野，使微创手术得以实现，为广大患者带来了福音。不知以上的介绍对你是否有用，你是否存有疑问，欢迎大家来我们网站http://www.jiangrenyiliao.cn联系提问！

If you want to use the endoscope well, you need to have a deep understanding of its principle. The endoscope extends the surgical field of vision, enables minimally invasive surgery to be realized, and brings gospel to the majority of patients.
