Endoscopy means looking inside and typically refers to looking inside any object for its non-accebality.

This is done by using an instrument called an endoscope.

This is particularly used by doctors for examination inside a human body.

Endoscopy can also refer to using a borescope in technical situations where direct line-of-sight observation is not feasible.

How done[]

Endoscopy is used to assess the interior surfaces of any object by inserting a tube into the equipment. The instrument may have a rigid or flexible tube and to provide an image for visual inspection and photography for further action.

In the case of engineers[]

It provides a visual image of the inside of a machinery, for further action.

In the case of doctors[]

A flexible endoscope.

In the case of doctors, where it is mostly used, for examination of a living body, it also enables taking biopsies and retrieval of foreign objects.


Many endoscopic procedures for use on living beings are considered to be relatively painless and, at worst, associated with mild discomfort.

Equipment components[]

An endoscope can consist of a rigid or flexible tube, (made for a specific purpose), with a light delivery system to illuminate the part or object under inspection.

The light source is normally outside and the light is typically directed via an optical fiber system. A lens (optics) system will transmit the image to the viewer from the fiberscope.


Endoscopy can involve many uses for engineers and surgeons.
