Hard tube endoscope is mainly composed of optical imaging system and lighting system. Outside the optical part is a slender metal tube, and inside is a complete optical system composed of many lenses. The optical imaging system consists of objective lens system, image relay system and eyepiece system.
The inverted image of the observed object is formed by the objective lens. The inverted image is converted into a positive image through the image relay system, and then transmitted to the eyepiece, which is enlarged by the eyepiece for human observation. In order to form different perspectives, different prisms need to be added.
Endoscopes for different purposes are made into different shapes, outer diameters and lengths according to the use requirements to meet the use requirements. The lighting transmission system is composed of optical fiber, which transmits the light of cold light source to the front end of endoscope through optical fiber to illuminate the observed object.
With the expansion of the scope of use of hard mirrors, various doctors use hard mirrors more and more frequently. Rigid endoscope is a relatively precise medical device, but as long as it is used and maintained properly, the damage can be avoided.
The endoscope maintenance personnel believe that the hard tube endoscope should be washed clean after use, and the water stains should be wiped dry. The hard tube endoscope shall be kept in a special cabinet by a specially assigned person and placed in a special box lined with soft sponge or polyurethane foam.
All rigid tube endoscopes and surgical instruments shall be stacked neatly without overlapping each other. Ensure that the internal endoscope and instrument will not collide with each other during transportation after the cover is closed. When the hard tube endoscope moves in the tray and other hard containers, pay attention to placing it separately from other instruments, and do not collide excessively to avoid collision with the endoscope.
When taking out or placing the rigid endoscope, put it flat with both hands and handle it gently. Because the barrel of the endoscope is very thin, it will bend and deform under extrusion, collision, bending, falling, etc., resulting in lens damage or optical axis offset, resulting in unclear image or inability to use, so take it out of the box. Or when placing the hard tube endoscope, gently take it out or put it in with both hands, and do not lift it out.
When you know the principle of hard tube endoscope, you need to understand its maintenance information. If you need endoscope, please pay attention to our website www.jiangrenyiliao.com Cn then consult.
