Abstract
The invention relates to a flexible optical fiber image transmission bundle and its preparation method and application. The flexible optical fiber image transmission bundle includes a plurality of flexible units, and the flexible unit includes a plurality of image transmission units arranged in a close-packed manner. The image transfer unit includes a skin glass layer and a core glass layer. The flexible optical fiber image transmission bundle prepared by the invention has a single fiber diameter of 4.0 μm to 5 μm, number of pixels ≥ 100,000, and a theoretical resolution greater than 100 lp / mm, featuring high resolution.
Description
technical field [0001] The invention relates to a flexible optical fiber image transmission bundle, a preparation method and application thereof, and belongs to the field of optical fiber image transmission bundles for medical endoscopes. Background technique [0002] Medical endoscope is a kind of medical endoscope that enters the human body through the natural orifice of the human body or a small surgical incision. It uses the principle of optical fiber image transmission, light transmission and its soft bending performance to conduct direct and rapid inspection and diagnosis and treatment of hidden parts that are not easy to be observed by the naked eye. a technology. With the vigorous development of minimally invasive surgery, medical endoscopes have been more and more widely used in modern medicine due to their outstanding advantages such as accurate diagnosis and treatment and small wounds, and have gradually become one of the important tools for humans to peep and tre...
