Endoscopes work amazingly. They allow doctors to have better visualization of the organs under close examination. One excellent type of endoscope is the Olympus 190 video processor. If the doctor wants to examine the stomach and intestines, for instance; then the endoscope, which is a flexible tube will be inserted into the patient through their mouth. Once it is already inside the body abdominal area, the doctor can start focusing on suspected problem organs.
What make it possible for doctors to visualize internal organs through this equipment are the optical cables, which have optical fibers. One optical cable carries light when the flexible tube is already inside the patient's body. The other optical cable has a reflected light, which allows doctors to see the internal organ through the eyepiece. This makes endoscopes valuable not only in establishing diagnosis but in doing surgeries as well.
