As a more convenient way of travel, civil aviation has been widely accepted and has become one of the most important means of transportation for modern people's business and travel. At the same time, aviation safety has always attracted people's attention. As the "heart" of the aircraft, aero engines are closely related to aviation safety. Nowadays, there are various non-destructive testing tools for testing and repairing it. The use of industrial endoscope for hole detection is one of the routine tasks. It does not need to disassemble and destroy the engine structure, and can perform efficient testing. Accident prevention plays an important role.

The working environment of civil aviation engines is very harsh, under high temperature and high pressure for a long time, the internal temperature is as high as 2000 ℃, so if the potential safety hazards are not eliminated in time, it may cause serious consequences. It is necessary to use videoscopes for regular non-destructive testing. So what aspects of the industrial videoscope can be used for inspection? Mainly in the following aspects:

After learning about the potential value of borescopes for identifying retained soil and debris, our team designed a study where the ports and channels of 20 colonoscopes and gastroscopes were carefully inspected three times during a seven-month period.7 Our goals were to determine whether damage and debris accumulated over time and whether more rigorous processing could completely eliminate contamination. This was the first time a medical borescope was used to prospectively monitor endoscope cleanliness and damage over time, so we had to develop our own protocol and reference materials.A wireless electronic endoscope that transmits signals by Wi-Fi is developed for use in single-hole endoscopic surgery and future application to natural orifice surgery. The innovative electronic endoscope developed in this study has a disposable design, completely preventing patents from taking risks of cross infection. The main components of the endoscope are a disposable component of the front tip and the hand-held part of the rear tip. The front tip consists of a lens, metallic tube, and electronic joint whereas the rear tip consists of a power switch, image converter, wireless transceiver chip, and antenna.

Why it's done

An endoscopy is sometimes combined with other procedures, such as an ultrasound. An ultrasound probe may be attached to the endoscope to create specialized images of the wall of your esophagus or stomach. An endoscopic ultrasound may also help your doctor create images of hard-to-reach organs, such as your pancreas. Newer endoscopes use high-definition video to provide clearer images.
Many endoscopes allow your doctor to use technology called narrow band imaging, which uses special light to help better detect precancerous conditions, such as Barrett's esophagus.

Risks

We observed recordings of pictures obtained from patients with diseases of the larynx by using a new type of rhino-larynx electronic endoscope, PENTAXVNL-1530 connected to a video processor, PENTAX EPM-3300 (Asahi Optical Co., Ltd.). The electronic endoscope differs from the fiberoptic endoscope in that it contains a small light-sensitive charge coupled device (CCD) chip that is attached to the tip of the endoscope. This electronic endoscope has the smallest CCD camera of 5.1 mm in diameter, in the tip portion, and can be passed through the nasal passage into the laryngeal cavity. The dynamic image provided by this system is superior to that obtained by a flexible laryngofiberscope in resolution of the detail.The system with this electronic endoscope was introduced and some clinical cases were presented.
