| Columbia Encyclopedia: endoscope |
endoscope, any instrument used to look inside the body. Usually consisting of a fiber-optic tube attached to a viewing device, endoscopes are used to explore and biopsy such areas as the colon and the bronchi of the lungs. Endoscopes employing miniature television cameras and tiny surgical implements now allow exploration and endoscopic surgery through small incisions; such surgery is much less traumatic to the patient than traditional open surgery. Laparoscopic surgery, in which the endoscope is inserted through a small incision in the abdomen or chest, is used to correct abnormalities of the ovaries and as an alternative to traditional gall bladder and chest surgery. Arthroscopic surgery is endoscopic surgery performed on joints such as the knee or shoulder.
| Veterinary Dictionary: endoscope |
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 of an endoscope may vary according to its 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. The endoscope also has a light source, power cord and power source. Accessories that might be used with an endoscope for diagnostic or therapeutic purposes include suction tip, tubes and suction pump; forceps for removal of biopsy tissue or a foreign body; and electrode tip for cauterization.
