Both industrial endoscopes and medical endoscopes are endoscopes in terms of name. Medical endoscopes appeared earlier. Industrial endoscopes are produced on the basis of medical endoscopes. The basic principles of the two are the same. According to the development and imaging structure, they can also be divided into: hard tube endoscopes, fiber endoscopes, electronic endoscopes, etc. So what is the difference between industrial endoscope and medical endoscope?

首先，從名稱上看，兩者的用途是不同的。工業內窺鏡是工業用途的無損檢測設備，能對彎曲管道深處以及人眼不能直視的部位進行觀測，能實現遠距離觀察與操作。采用工業內窺鏡，無需拆卸或損壞，就可以方便而且迅速地檢查各種機器、設備、組裝物體的內部，在石油化工、汽車零部件制造、警用安保、軌道交通等行業，都有著廣泛的用途。

First of all, from the name point of view, the two purposes are different. Industrial endoscope is a non-destructive testing equipment for industrial use. It can observe the depth of curved pipeline and the parts that can not be looked directly by human eyes, and can realize long-distance observation and operation. The industrial endoscope can easily and quickly inspect the interior of various machines, equipment and assembled objects without disassembly or damage. It is widely used in petrochemical, auto parts manufacturing, police security, rail transit and other industries.

醫用內窺鏡是一種常用的醫 療器械，主要用于對人體的常規醫 療檢查和外科手術中，使用時，將內窺鏡經人體的天然孔道，或者是經手術做的小切口導入待檢查的器官，可直接窺視有關部位的變化，配合使用其他手術器械就可以在體外進行體內的密閉手術操作。具有操作靈活簡便、減少病患痛苦、提高 效率等優點，醫用內窺鏡的功能性微創手術技術已近得到醫生和患者的廣泛接受。

Medical endoscope is a commonly used medical instrument, which is mainly used in the routine medical examination and surgical operation of the human body. When in use, the endoscope is introduced into the organ to be examined through the natural pore of the human body or the small incision made by the operation, which can directly spy on the changes of relevant parts. Combined with other surgical instruments, the closed surgical operation in the body can be carried out in vitro. It has the advantages of flexible and simple operation, reducing patient pain and improving efficiency. The functional minimally invasive surgery technology of medical endoscope has been widely accepted by doctors and patients.

其次，因為用途不同，兩者對材料、成像等方面的要求也不同。因為醫用內窺鏡伸到人體內與人體會接觸產生摩擦，為了避免產生不適感以及不必要的損傷，所以通常選用比較柔軟的材料。而工業內窺鏡一般是伸到工業設施內部，經常與金屬等堅硬材質摩擦，所以通常選用耐磨性較好的材料(如鎢鋼絲)做外層。此外，兩者的成像雖然都是清晰的，但是前者的用途是觀察人體內部器官，因此更關注圖像的色彩和柔和度;而工業內窺鏡的觀察對象是相對狹小空間內的金屬，因此需要考慮金屬反光、照明強度等問題，以確保成像的清晰。

Secondly, because of different uses, they have different requirements for materials and imaging. Because the medical endoscope extends into the human body and will contact with the human body to produce friction, in order to avoid discomfort and unnecessary damage, relatively soft materials are usually selected. Industrial endoscopes generally extend into industrial facilities and often rub with hard materials such as metal, so materials with good wear resistance (such as tungsten steel wire) are usually used as the outer layer. In addition, although both images are clear, the former is used to observe the internal organs of the human body, so it pays more attention to the color and softness of the image; The observation object of industrial endoscope is the metal in a relatively narrow space, so it is necessary to consider the problems such as metal reflection and lighting intensity to ensure the clarity of imaging.

以上對工業內窺鏡和醫用內窺鏡的不同之處進行了簡要的介紹。目前，有的內窺鏡廠家兩種產品都有，有的廠家則是從醫用內窺鏡起家，后轉向工業內窺鏡。

The differences between industrial endoscope and medical endoscope are briefly introduced. At present, some endoscope manufacturers have both products, while others start from medical endoscopes and then turn to industrial endoscopes.
