Endoscope illumination optical system

Abstract

The invention discloses an endoscope illumination optical system which comprises a shell. An intubation tube is fixedly connected to the surface at one end of the shell, a camera tube is fixedly connected to the center of the interior of the intubation tube, and a camera is fixedly installed on the surface at one end of the camera tube; the surface at one end of the camera is fixedly connected to the center at one end of the intubation tube, optical fiber tubes are fixedly connected to the surfaces at the two sides of the intubation tube, and a condensation column is fixedly connected to the side face of one end of each optical fiber tube; the surfaces of the optical fiber tubes are fixedly connected to the surfaces at the two sides of the camera tube, the side face of the intubation tube is fixedly filled with a filling layer, and the surfaces of the camera tube and the optical fiber tubes are fixedly wrapped with the surfaces of the filling layer. A light shielding plate is rotationally installed on the side face at one end of the shell, a through hole is formed in the surface of the light shielding plate, and the surface at one side of the through hole is in butt joint with the surface at one end of the optical fiber tube, so that the use convenience and stability can be greatly improved, and the adjustment safety and illumination uniformity are guaranteed.

Description

technical field [0001] The invention relates to the field of endoscopes, in particular to an endoscope illumination optical system. Background technique [0002] In the current medical treatment, the use of endoscopes is becoming more and more common. By embedding the camera and light source inside the cannula, it can be inserted into the human body for inspection, which is conducive to the detection of lesions and effectively improves the safety and efficiency of diagnosis and treatment. [0003] However, in the existing endoscope lighting structure, most of the light tubes and camera tubes are distributed to the two sides of the intubation tube, which will easily cause the position of the light to deviate from the alignment point of the camera, resulting in interlaced light and dark and affecting the clarity. , and the existing structure is not conducive to adjusting the light of multiple light points according to the needs, and it is easy to cause lens glare due to partia...
