This Product Comparison covers multicomponent video endoscopy systems for all types of diagnostic and therapeutic procedures that use rigid and flexible endoscopes; some systems can also be used during operative microscopy. Video endoscopy systems allow the viewing of live, color im ages of the interior of the body during diagnostic and therapeutic endoscopic procedures. They also enable these images to be stored, retrieved, and otherwise electronically manipulated. The endoscopes are inserted through natural openings in the body or through small punctures; therefore, MIS procedures are much less traumatic than open surgical procedures and result in less discomfort and usually in shorter recovery periods. Consequently, some procedures can be performed on an outpatient basis. Laparoscopy allows minimally invasive examination and treatment of organs and tissue within the peritoneum during procedures such as cholecystectomy and appendectomy that previously required open abdominal surgery. Arthroscopy, an alternative to open arthrotomy, enables the diagnosis and treatment of many joint diseases and injuries. In gastrointestinal endoscopy, a flexible endoscope is inserted into the rectum or esophagus, allowing the examination and removal of foreign bodies and polyps and the diagnosis of ulcers and cancer. Video endoscopy systems comprise modular image detection/processing systems, monitors, and recording devices, as well as other accessories such as insufflators, irr igation and suction pumps, and carts. The main components of the video image detection system are the endoscope, camera head adapter (if required), processor, and fiberoptic light source. The image detection system uses a photosensitive silicon sensor, called a charge coupled device (CCD) or chip, which is composed of thousands of photoelectric picture elements (pixels) arranged in a rectangular grid. Using a fiber optic light source for illumination, the lens system focuses the Light reflected from the field of view onto the CCD’s pixels, which electronically capture the image. Standard two - dimensional (2 -D) Video endoscopy systems use either one or three monochrome CCDs.
