Endoscope vs. Fiberscope



An instrument used to examine a bodily orifice or canal, or a hollow organ.


(American spelling) a flexible fibreoptic device for viewing otherwise inaccessible areas


An instrument for examining the interior of the body, consisting of a flexible tube with lenses and optical fibers permitting illumination of the interior site to be inspected, and visualization of the interior site from outside the body; it often has small surgical instruments attached to the end and manipulable from the outside, permitting biopsy or surgery. It is used as a non-invasive or minimally invasive tool for diagnosis or treatment, especially in organs having an external opening such as the rectum, the urethra, and the bladder.


an instrument used to examine internal organs.


a long slender medical instrument for examining the interior of a bodily organ or performing minor surgery


a flexible medical instrument involving fiber optics that is used to examine internal organs



An endoscope is an illuminated optical, typically slender and tubular instrument (a type of borescope) used to look deep into the body and used in procedures called an endoscopy. Endoscopes use tubes which are only a few millimeters thick to transfer illumination in one direction and high-resolution images in real time in the other direction, resulting in minimally invasive surgeries.


A fiberscope is a flexible optical fiber bundle with an eyepiece on one end and a lens on the other that is used to examine and inspect small, difficult-to-reach places such as the insides of machines, locks, and the human body.
