Three-dimensional endoscope system and endoscopic imaging system compatible with two-dimensional endoscopes

Abstract

The invention discloses a three-dimensional endoscope system compatible with two-dimensional endoscopes. The three-dimensional endoscope system comprises a first object lens, a second object lens, a first image transmission column, a second image transmission column, a first image diaphragm, a second image diaphragm, a first focusing lens group, a second focusing lens group, a first deflection prism, a second deflection prism, a first cylindrical lens and a second cylindrical lens. The three-dimensional endoscope system has the advantages that the first deflection prism is used for reflectingfirst light beams which are received by the first focusing lens group and are projected from the first focusing lens group, the second deflection prism is used for reflecting second light beams whichare received by the first focusing lens group and are projected from the second focusing lens group, accordingly, the distances between the optical axes of the first light beams and the second light beams can be changed, and the three-dimensional endoscope system can be matched with image sensors of two-dimensional endoscope systems; the first cylindrical lens is used for compressing the first light beams reflected from the first deflection prism, the second cylindrical lens is used for compressing the second light beams reflected from the second deflection prism, and accordingly flattened first images and flattened second images can be acquired by first light sensing regions and second light sensing regions of the image sensors.

Description

technical field [0001] The technical field of three-dimensional imaging of the present invention particularly relates to a three-dimensional endoscope system compatible with two-dimensional endoscopes and an endoscope imaging system. Background technique [0002] In recent years, with the development and popularization of minimally invasive surgery, medical endoscope systems for human treatment have been widely used in orthopedics, spine surgery, gynecology, urology and neurosurgery. [0003] A patent document with publication number CN104935915A discloses a three-dimensional endoscope, which includes an insertion tube and a three-dimensional imaging unit. Wherein, the three-dimensional imaging unit includes an image sensor and a first lens and a second lens integrated in the insertion tube; the first lens and the second lens are used to capture images of the same scene at the same time to obtain the first image with parallax and The second image; the first lens includes a ...

AI Technical Summary

Problems solved by technology

[0005] At present, most hospitals in my country are still using two-dimensional endoscopy systems. If these two-dimensional endoscopy systems are replaced by expensive three-dimensional endoscopy systems, it will cost a lot of money, which is not conducive to reducing the cost of patient treatment, but also During the replacement process, a large number of idle 2D endoscopy system equipment will be generated

[0006] In addition, in addition to the above-mentioned 2D medical endoscope system for human medical treatment, the 2D medical endoscope system for animal medical treatment and the 2D industrial endoscope system for industry also have the same compatibility issues
