From the application side, the simple ones can be divided into two categories, namely industrial endoscopes and medical endoscopes.
Regarding the types of industrial endoscopes, they are classified from the form of imaging: optical endoscopes, fiber optic endoscopes, electronic endoscopes, CCD video endoscopes, CMOS video endoscopes, and electric 360° endoscopes. From the type of endoscope light source, it is divided into high frequency fluorescent lamp endoscope, fiber optic halogen lamp endoscope, and LED endoscope.
Regarding medical endoscope classification, according to its development and imaging structure classification: can be roughly divided into three categories: hard tube endoscope, optical fiber (hob type) endoscope and electronic endoscope.
There are many different types of medical examination endoscopes, and the classification methods are different. Generally speaking, the following three classification methods are generally used. In terms of market sales, the most widely used categories are classified into hard mirrors and elastic soft mirrors in terms of clinical changes.
Press the function of the endoscope
Divided into single-function mirrors and multi-function mirrors. A single-function mirror refers to an observation mirror that has no working channel and only an optical system. The multi-function mirror refers to a function of having a viewing mirror, and has at least one working channel in the same mirror body, with illumination, surgery, irrigation, and Attracting and other functions.
Press the end of the endoscope
Classified according to the location of the endoscope: ENT, endoscopic, dental endoscopy, neurosurgery, urethroscopic cystoscopy, resectoscope, laparoscopy, arthroscopy, sinus surgery, Laryngoscope and so on.
According to whether the mirror body can change direction
Clinically, according to whether the endoscope body can change direction, it can be classified into two types: hard mirror and elastic soft mirror. RIGID ENDOSCOPE is a prismatic optical system. The biggest advantage is that the imaging is clear. It can be equipped with multiple working channels and multiple viewing angles can be selected. Flexible flexible lens (FLEXIBLE ENDOSCOPE) is an optical fiber optic system. The most important feature of this fiber optic endoscope is that the lens part can be manipulated by the operator to change the direction and expand the scope of application, but the imaging effect is not as good as a hard mirror.
