These ubiquitous endoscopes

Endoscopes for inspection of the abdominal cavity. Modern endoscopes for gastroenterology allow you to explore different parts of the digestive tract. A variety of functional assignments gastrointestinal endoscopes defines a big difference in technical and design their device.
Easily accessible areas of the digestive tract is studied with the help of the hard appliances, representing a hollow metal tube or set of pipes, through an opening which is under study.
The deep divisions of the digestive system available to the investigation through application of flexible endoscopes.
In modern gastrointestinal endoscopes are used fiber, fiber optic cables for transmission of light from a stationary source to the object under investigation. Depending on the design of the device transmitting system is mounted in a rigid or flexible tube endoscopes.
The use of glass fiber light-absorbing systems in rigid and flexible endoscopes provides high levels of illumination on the object and creates favorable conditions for a detailed inspection and monitoring conducted through endoscopes manipulations. In flexible endoscopes good illumination of an object, the remote at a considerable distance from the observer's eye, provided only the transmission of light from a powerful stationary source for flexible fiber. The use of rigid and flexible endoscopes fiber transmission system eliminates the risk of thermal damage to the mucosa of the authorities.
Flexible gastrointestinal endoscopes equipped with a fiber optic system, which transfers the image from the object to the eye of the observer on fibre channel. The use of fiber optics in optical channel unit ensures unchangeable quality of the image object without cutting the field of view in any bending of the device.
Thanks managed to bend the distal end facilitated the holding of an endoscope in curved channels of the digestive tract. The management of the bending arm is set in motion with one hand and placed on the body of the eyepiece end of the device where you installed the mechanisms for device control. The handle is equipped with a pointer bending angle. Devices have device allowing to fix a curved distal end in any position.
Almost all of gastrointestinal endoscopes fitted with devices for discharge into the air. In flexible endoscopes air injection is carried out through a special channel through which can also be entered liquid. Injected into the cavity, the air spreads folds of mucous membrane of the studied organs and remove them from the working end of an endoscope, which creates conditions for a good inspection.
The design of devices with mechanical position optics provides aimed announcement of water or air on the protective glass lens optical system in order to clean it. The devices also provide for the possibility of extraction of secret or mucus from the study cavity through a catheter. Endoscopes intended for realization of medical manipulations, supplied with flexible instruments held through a special channel devices. Using the included device brush channel can be cleared of mucus.
Flexible endoscopes, is inserted through the mouth, equipped with special plastic bushings-mouthpiece, excluding the possibility of damage during the study.
To facilitate the introduction of flexible endoscopes through the rectal opening and further along the intestine their distal ends of the ring-tips.
The initial inspection Department of the digestive tract from the esophagus can be carried out using ezofagoskopia pipes included in the sets of bronchoesophagology BEF-1 and bronchoesophagology Mezrina BEF-2,
For inspection of the stomach is esophagogastroscopy flexible biopsy with fiber optics Aigues-IN-1 and gastroduodenoscopy flexible biopsy with fiber optics DG-IN-1. Using the latest device, you can explore the duodenum. The common bile duct examined during surgery of biliary tract hard-optical device choledochoscope; with his help can be removed stones from the duct and implemented other manipulations.
Direct and sigmoid colon successfully investigated by rectoscope different scope and types and a sigmoidoscope with fiber optics-IN-1; diagnostics proctologic diseases through research of microstructures of the mucous membrane of the rectum using reccontrol.
The digestive tract, located in the abdominal cavity, become available to the eye of the observer through the use of a laparoscope with the optical fiber. Rigid and flexible endoscopes are outside marking the depth of the introduction of the unit into the cavity.
Flexible endoscopes optical systems designed for observation of the object in the range from 10 to 100 mm Eyepieces have the dioptric focusing ±5 diopters.
Flexible endoscopes with fiber optics work, as a rule, complete with illuminator OS, hard appliances - with illuminator OS-150 or OS-100.
