an instrument used for direct visual inspection of hollow organs or body cavities. Specially designed endoscopes are used for such examinations as bronchoscopy, cystoscopy, gastroscopy, and proctoscopy. Although the design may vary according to the specific use, all endoscopes have similar working elements. The viewing part (scope) may be a hollow metal or fiber tube fitted with a lens system that permits viewing in a variety of directions. There is also a light source, power cord, and power source. Accessories that might be used for diagnostic or therapeutic purposes include suction tip, tubes, and suction pump; forceps for removal of biopsy tissue or a foreign body; biopsy brushes; an electrode tip for cauterization; as well as a video camera, video monitors, and image recorder.

endoscopeAn internal viewing instrument. Modern endoscopes are steerable, flexible, cylindrical instruments with fibre optics for illumination and viewing and channels to allow washing of the area under view, suction, gas inflation to ease viewing, the taking of BIOPSY specimen and the use of various small operating instruments, including LASERS.

An endoscope as used in the field of gastroenterology is a thin flexible tube which uses a lens or miniature camera to view various areas of the gastrointestinal tract. When the procedure is performed to examine certain organs such as the bile ducts or pancreas, the organs are not viewed directly, but rather indirectly through the injection of x-ray dye. The performance of an exam using an endoscope is referred by the general term endoscopy. Diagnosis through biopsies or other means and therapeutic procedures can be done with these instruments.

Instrument designed to examine cavities which are not accessible for direct examination with the eye. It usually incorporates fibre optics to increase the flexibility of the instrument. Examples: a laryngoscope which is introduced through the mouth to examine the larynx; an ophthalmic endoscope to examine the intraocular structures by inserting a fibre optics system through the sclera, as may be used in ocular surgery.
