Composition of electronic endoscope system

The whole set of electronic endoscope system is mainly composed of three main parts: endoscope, TV information system center and TV monitor. In addition, CCD coupling cavity mirror, intracavity cold light lighting system (currently LED light source), video processing system, and display printing system are the main components of the electronic endoscope. The composition of the electronic endoscope is also equipped with some auxiliary devices, such as video recorders, cameras, suction devices, keyboards for inputting various information, and various treatment tools for diagnosis and treatment. Electronic endoscopy plays a very important role in the diagnosis and treatment activities of endoscopy rooms in large and medium-sized hospitals in China. It has the advantages of high resolution, easy diagnosis, small diameter and long service life. The main disadvantage is that it is easily damaged, and ordinary users cannot repair it, and the maintenance cost of the manufacturer is high.
In terms of detailed components, the electronic endoscope mainly includes a tip bending part, an insertion part, an operation part, and an electrical connector part. The tip bending part is the front end of the endoscope, which is composed of water/air supply nozzle, light guide, objective lens, forceps pipe outlet, bending rubber, etc. The outside of the insertion part is a scaled outer skin, and the inside is wrapped with a guide beam, an image guide bundle, a water/air supply pipe, a forceps pipe and a drum steel wire. The operation part is the hand-held part for doctor's examination and treatment, mainly including angle control rotor, latch, function button, suction piston, water/air supply piston, pliers pipe inlet, etc. The electrical connector part is the part of the electronic endoscope that connects the cold light source and the image processing system, and is composed of electrical connectors, light guide connectors, water/air supply connectors, and suction connectors. The parts that move most frequently in diagnosis and treatment activities: One is the operation part, including the air/water supply button, suction button, live picking channel, angle button, etc. The second is the mirror body. The mirror body is a flexible insertion tube made of steel mesh tube and serpentine steel tube. The guide beam, guide beam, biopsy/suction channel, gas injection/water injection are contained in the tube diameter less than 1cm. Pipes and steel wires for controlling angles, etc. Outsourcing is covered with a polyurethane plastic tube, which has a sealing and anti-corrosion effect to prevent water and gastric juice from entering and corroding. Once these two parts that work frequently are damaged, professionals must be asked to repair them with special tools and special accessories, and the cost is high and the time is long. Therefore, correct operation and careful maintenance are of great significance to prevent and reduce the failure of electronic endoscopes and prolong their service life.
