內窺鏡的出現，不僅延展了手術醫生的眼睛，而且其分辨率、清晰度都大大增加。今天內窺鏡設備維修人員就帶大家一起來學習一下內窺鏡的基本知識。

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.

內窺鏡是一種常用的醫療器械.由導光束結構及一組鏡頭組成。經人體的天然孔道或經小切口進入人體內，通過設備外部成像用于人體器官或組織的檢查及手術治療。而臨床上常用的腹腔鏡屬于硬式內窺鏡，是指利用一系列光學柱狀晶體透鏡將影像傳送到接目鏡，并通過連接獨立攝像頭進行成像的設備。

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.

內窺鏡的分類

Classification of endoscopes

按成像原理分：光學鏡（柱狀透鏡）、纖維鏡、電子鏡

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

按功能分：腹腔鏡、膀胱鏡、關節鏡、胃腸鏡、膽道鏡等

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

按形態分：硬式內窺鏡、軟式內窺鏡

According to morphology: hard endoscope, soft endoscope

按用途分：腹腔鏡、電切鏡、鼻竇鏡等

Classified by purpose: laparoscope, resectoscope, sinusoscope, etc

按角度分：對于角度的描述多數指的是硬式內窺鏡，根據檢查部位的要求，提供不同的視野角度，可分為0°、12°、30°、70°等，應用于不同的手術科室。

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.

內窺鏡有多種角度可選，我們可以通過不同的顏色標識就可以知道鏡子的角度，具體如下：

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

看了這么多角度的鏡頭，是不是會有一種想法，能不能把各種角度的鏡頭合為一體呢？近年來，就有了一種新鏡頭—變色龍鏡（EndoCameleon），它在0°-120°之間可以調整視野角度，通過旋轉調節鏡頭前端的物鏡，實現視向角度無縫切換，與現有的10mm腹腔鏡鏡頭相比，大大擴展了應用范圍!

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!

要想用好內窺鏡就要對其原理有深入的了解，內窺鏡延展了外科視野，使微創手術得以實現，為廣大患者帶來了福音。不知以上的介紹對你是否有用，你是否存有疑問，歡迎大家來我們網站http://www.cnxgtzyj.cn聯系提問！

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.
