Description: Endoscopy is a method or process to inspect the internal organs like stomach and gastro intestinal test of the body. It works on the principle of fiber optic communication by using fiber optic cables with fiber optic technique. Fiber optic cable is simply a bundle of microscopic glass or plastic fibers that literally allows light and images to be transmitted through curved structures. Fiber optic cables are also replacing metal wires as backbone of world’s telecommunication infrastructure. It comprises many advantages:
1. Very high bandwidth
2. Very high weight and small size
3. Low loss compared with other media
4. Freedom from electromagnetic interference
Endoscopes uses two fiber lines: A light fiber carries into the body cavity and an image fiber carries the image of the body cavity of the physician’s viewing lens. There is also a separate port to allow for administration of drugs, suction and irrigation. This port may also be used to introduce small folding instruments such as foreceps, scissors and basket for tissue excision, sampling or others work. Endoscopes may used in conjuction with a camera or video recorder to document images of the inside of the joint or chronicle an endoscopic procedure.
Internal abnormalities revealed through endoscopy include abscesses, biliary cirrhosis, bleeding, cancer, cysts, degenerative disease, hernia, ulcers and others.
