Abstract

The invention discloses an endoscope comprising a head end structure, a bending part connected with the head end structure, an insert tube connected with the bending part, a handle connected with the insert tube and a display screen installed on the handle; the head end structure is provided with a shooting assembly and light guide fiber therein; the shooting assembly comprises a high definition object lens and a camera; a section of an inner hole of the head end structure has a four-leaf clover shape structure, wherein four waist-shaped holes of the four-leaf clover shape structure are filled with the light guide fiber. The diameter [phi] of the insert part of the endoscope is 3mm and the periphery of the endoscope can be illuminated; clear determination images can be obtained in a small diameter pipeline (chamber channel) through a stable illumination environment and can be transmitted to a host display screen; shooting angles can be conveniently adjusted for observation.

Description

technical field [0001] The invention relates to a detection instrument based on a pipeline or cavity, in particular to an endoscope. Background technique [0002] In the diagnosis and treatment process of modern medicine, people are increasingly pursuing clear judgment pictures and non-invasive or minimally invasive treatment results. Therefore, the diameter and uniform illumination of the camera placed at the front end of the endoscope have become technical difficulties. However, the existing products basically cannot meet the requirements in terms of small diameter and uniform illumination of the picture. [0003] It is also an urgent need for users to detect small-diameter pipes (cavities) in the industrial field and obtain satisfactory images. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide an endoscope with an insertion part diameter of Φ3 mm and an endoscope that can form illumination around the camera he...
