Endoscope is a kind of traditional optics, ergonomics, precision machinery, modern electronics, mathematics, software and other testing instruments, with image sensors, optical lenses, light source lighting, mechanical devices, etc., can be entered into the body as well as the machine internal inspection, is widely used in the field of medicine and industry.
Two, what does endoscope do
Endoscope can be divided into industrial endoscope and medical endoscope according to different application fields, and their roles are different:
1, what kind of examination does medical endoscope do
(1) Examination of gastrointestinal diseases: including chronic esophagitis, esophageal varices, esophageal foramen hernia, chronic gastritis, gastric ulcer, benign gastric tumors, small intestinal tumors, smooth muscle tumors, sarcomas, polyps, colon polyps, colorectal cancer and so on.
(2) Examination of pancreatic and biliary tract diseases: pancreatic cancer, cholangitis, cholangiocarcinoma and so on.
(3) Laparoscopy: liver disease, biliary system disease, etc.
(4) Examination of respiratory tract diseases: lung cancer, transbronchoscopic lung biopsy and brush test, selective bronchography, etc.
(5) Examination of urinary tract: cystitis, bladder union, bladder tumor, renal tuberculosis, renal stone, renal tumor, ureteral congenital malformation, ureteral stone, ureteral tumor and so on.
(6) Endoscopic surgery: application of the speculum that can be sent into the human body cavity for treatment under visualization.
2, the use of industrial endoscopes
(1) construction industry: mainly used for the inspection of holes, walls, doors, windows, joints and water pipes and other places that are not easy to be viewed by the naked eye; central air-conditioning, TV, and network cable installation and testing, and so on.
(2) Oil, gas and chemical industry: Due to the special characteristics of the oil, gas and chemical industry and the extremely high requirements for safety, the large pipelines, irregular containers, and slender seamless steel tubes in the industry all need specialized special industrial endoscopes to carry out detailed inspections of their internal pipe walls.
(3) Mechanical overhaul: large mechanical equipment and some due to the high temperature, toxic or too small environment of the machine work observation can be industrial endoscopy.
(4) security monitoring: endoscopes can be used for security inspection, customs and other aspects of the detection of baggage, parcels and other packaged goods, without having to open the package and can be inspected, not only to ensure the efficiency of the security personnel to protect the privacy of the goods being detected.
(5) automotive overhaul: can be used for automotive engines, fuel tanks, braking systems and other places where the naked eye can not be directly seen, with the increase in the number of private cars and the rise of DIY trend, the image clarity of a higher degree of small portable electronic video endoscopes will gradually become a part of the household toolbox.
(6) electric power facilities: in the overhaul to detect the turbine blades, guard ring and stress concentration parts of the micro-cracks, power plants in the generator set as well as the equipment need to run and work for a long time, regularly through the endoscope on its internal operation, damage inspection is essential.
(7) pipeline chemical: mainly used to check the process piping, pressure vessels, reactors, heat exchangers and other welded joints inside surface welding quality, stress corrosion cracks and chemical corrosion of the inner wall and other defects.
(8) Aerospace: used to check the turbine engine blades and ring guards for damage than the traditional hand touch inspection is more accurate and efficient.
(9) Boiler and combustion engine: used to inspect boilers, gas turbines, diesel engine piping.
