AI Technical Summary

Technical Problem

Existing flexible electronic endoscopes lack pressurized irrigation and active suction functions, resulting in unclear vision, difficulty in drainage, and external equipment limits their application locations and portability.

Method used

A small peristaltic pump is built into the endoscope handle to achieve pressurized irrigation and reverse suction functions. The built-in peristaltic pump can independently control the speed and direction, and the endoscope can have its own irrigation and suction functions.

Benefits of technology

This has enabled the portability and expanded applicability of flexible electronic endoscopes, allowing them to be used in multiple locations, improving examination results, and aligning with the development trend of wireless instruments.

Abstract

The present invention relates to a medical instrument, and in particular, to a flexible electronic endoscope with a built-in peristaltic pump. The technical problem to be solved by the present invention is that current flexible electronic endoscopes themselves do not have the function of pressurized perfusion, resulting in the problems of limited space and poor portability when externally connected to perfusion pumps and externally connected to negative pressure pipelines. The present invention provides a flexible electronic endoscope with a peristaltic pump built into a handle. A lavage pipe of the endoscope is provided with a small peristaltic pump, both ends of a pump tube of the peristaltic pump are connected to the lavage pipe, and the pump tube forms a part of the lavage pipe. In this way, the flexible electronic endoscope is allowed to have an independent pressurized perfusion function.
