Russia has created the first domestic endoscope

Russian developers with the participation of St. Petersburg State Electrotechnical University «LETI» named after V.I. Ulyanov (Lenin) have developed the first domestic endoscope. As the authors of the project told Izvestia, endoscopic examinations have now become one of the most common types of high-tech medical diagnostics, which is associated with a high level of information content, the possibility of detecting oncological diseases and neoplasms in the early stages.

The specialists have created a video module with an LED light source for image generation, a video processor for signal processing, software to enhance the information content of the generated image, as well as to implement all service functions, including maintaining a patient database.

One of the important steps of this work was the introduction of a chromoendoscopic module into the new endoscope to expand the device's functionality. Virtual chromoendoscopy, that is, a method of examining the organs of the gastrointestinal tract, in which the mucous membranes are stained with contrasting dyes for accurate visualization of pathological areas, is an important direction for increasing the diagnostic value of images presented to the doctor, the developers said. This method simplifies the diagnosis of gastrointestinal pathologies in the early stages.

"All top foreign manufacturers of endoscopic equipment, such as Olympus and Storz, have virtual chromoendoscopy technologies, but this is, of course, classified information. We have developed our own innovation, which in some aspects even surpasses existing solutions, as it includes four image processing modes. This includes a unique mode that provides a combination of optimal color contrast while maintaining the natural color gamut," Natalia Obukhova, Dean of the Faculty of Radio Engineering and Telecommunications (FRT), Head of the Department of Television and Video Engineering (TV) at St. Petersburg State Technical University LETI, told Izvestia.

At the moment, a software module is being developed for the early diagnosis of intestinal gastric metaplasia (a precancerous condition associated with negative changes in the cells of the gastric epithelium).
