AI Technical Summary

Technical Problem

The outer contour of the tip of existing endoscopes is relatively large, making it difficult to insert into human cavities. Furthermore, the installation process requires the use of baffles to separate the cavities, which increases the material usage and assembly time.

Method used

The mounting cavity is divided into an independent working cavity and an illumination cavity by using a camera module. The illumination component is installed in the illumination cavity, and the working channel tube passes through the working cavity and is fixed by limiting parts and sealant, avoiding the use of baffles for separation.

Benefits of technology

The outer contour dimensions of the tip structure have been reduced, minimizing harm to patients, improving assembly efficiency, reducing costs, and ensuring stable component installation.

Abstract

The utility model relates to an endoscope and a tip structure thereof. The tip structure comprises a shell, a camera module, a lighting module and a working channel pipe, the shell is provided with a mounting cavity, and the mounting cavity penetrates through the front end and the rear end of the shell. The camera module is fixed in the mounting cavity, divides the mounting cavity into a working cavity and a lighting cavity which are mutually independent, and is used for acquiring an image of the target area. The illumination assembly is arranged in the illumination cavity and used for illuminating the target area so as to provide a clear view for the camera module. And the working channel tube is arranged in the working cavity in a penetrating manner and is used for perfusing or penetrating a surgical instrument. According to the endoscope and the tip structure thereof, the outer contour size of the tip structure can be effectively reduced, so that the tip structure can penetrate into a human body channel more easily, and harm to a patient is reduced.
