Medical Applications of Endoscope

Endoscope is an optical instrument with a history of 200 years since its appearance. With the rapid development of advanced scientific technology, endoscopes have made great progress in terms of types and levels, ranging from rigid and fiber endoscopes to electronic endoscopes and ultrasonic electronic endoscopes. Due to the advantages of thinner outer diameter, clearer and more intuitive images, and convenient operation, electronic endoscopes are gradually replacing fiber endoscopes.

Medical Applications of Endoscope

In the late 1960s, as a new technology, fiber optic manufacturing technology was quickly applied to medical equipment. Due to the good ability and quality of fiber optic transmission of light, as well as its flexibility and suitability for making soft endoscopes, the fiber endoscope system consists of an endoscope body and a cold light source.

Inside the body of the fiberoptic endoscopy are two fiber optic bundles: one called the light beam, which is used to conduct the light produced by the cold light source to the surface of the object being observed, illuminating the surface being observed. The other, called an image beam, arranges tens of thousands of fiber optics with a diameter of less than 1 micrometer in rows, with one end aligned with the eyepiece and the other end aligned with the surface under observation through a lens. Without distortion, it can transmit images from one end to the other. Doctors can see the surface of organs very intuitively through the eyepiece, which is helpful for early and accurate diagnosis.
