Medical endoscopes are divided into three categories of products, the first category: rigid endoscope series; the second category: fiber endoscope series; the third category: electronic video endoscope series. Today we will learn about fiberoptic endoscopy.
Fiberscopes, also known as flexible endoscopes, transmit images from the distal end to the proximal end through optical fibers. Fiberscopes are very flexible and flexible, and can detect complex tortuous, irregularly shaped areas and pipes that are beyond vision. inside and easy to operate.
The medical principle of fiberoptic endoscope:
The working principle of fiber endoscope is to transmit images by high-quality imaging fibers, and observe directly through the eyepiece. The fiberoptic endoscope consists of an insertion part (a front end part, a bending part and a flexible part), an operation part and an eyepiece part. The image transmission fiber bundle, optical fiber and steel wire for adjusting the front-end swing angle are all built-in. And also equipped with a dedicated cold light source.
The main body of the fiberscope can softly extend the human eye into the object to be detected, and can curve to change any direction of sight, which cannot be achieved by rigid endoscopes.
The imaging principle of the imaging fiber bundle is that it is composed of tens of thousands of glass fiber monofilaments into an imaging bundle, and each monofilament is an imaging element. The more monofilaments in an imaging bundle with the same diameter, the more The clearer the transmitted image, the longer the product life. The normal life of the image beam is generally seven years. When using it, you should pay attention not to fold the speculum hard to avoid stress.
Application of fiber endoscope:
In addition to being used as a rigid endoscope, fiberoptic endoscopes have expanded detection ranges due to their soft body and long effective working length. Used to inspect the inside of narrow diameter pipes or holes, the inside of castings/hydraulic parts/milled holes, the side walls of 10mm or larger diameter holes, the inside of aircraft engines, hollow walls or buildings, machinery, structures, etc., suitable for deep The inspection of the smoothness and roundness of the inner wall of holes and pores, the judgment and position determination of capillary pipeline blockage, and the inspection of the welding quality in the pipeline are also quite effective. It is an ideal tool for inspecting automobile cylinder blocks, aero engines and ship engines.
The above briefly introduces the medical endoscope series: fiber endoscope, welcome to consult!
