Electronic endoscope for medical imaging

Abstract

The invention belongs to the technical field of medical imaging equipment, and particularly relates to an electronic endoscope for medical imaging. The electronic endoscope includes an insertion tube;the two ends of the insertion tube are fixedly connected to a handheld part and an endoscope lens respectively; the endoscope lens is connected to a control imaging display device through wires and optical fibers which are arranged in the handheld part and the insertion tube; the endoscope lens comprises a tubular endoscope body, one end of the endoscope body is fixedly connected to the insertiontube, and the other end of the endoscope body is fixedly connected to a lens; an annular mounting seat is fixedly connected into the endoscope body, and a group of optical fibers for illumination areuniformly distributed on the periphery of the mounting seat; a flexible objective lens is arranged in an annular groove formed in the inner periphery of the mounting base, and a CCD video line is arranged at one end, away from the lens, of the objective lens; an annular cavity is formed in a position, close to the outer edge, of the objective lens, and the annular cavity is filled with magnetofluid; and an electromagnet surrounding the periphery of the objective lens is arranged at the bottom of the annular groove, and the electromagnet is connected to the control imaging display device through a wire. The focal length of the objective lens is controlled through the electromagnet, and the definition and the identification degree of the endoscope are improved.

Description

technical field [0001] The invention belongs to the technical field of medical imaging equipment, in particular to an electronic endoscope for medical imaging. Background technique [0002] Endoscope is a testing instrument that integrates traditional optics, ergonomics, precision machinery, modern electronics, mathematics, and software. One has image sensors, optical lenses, light source lighting, mechanical devices, etc., and it can enter the stomach through the mouth or enter the body through other natural channels. The endoscope can be used to see lesions that cannot be seen on X-rays, so it is very useful for doctors. For example, with the help of an endoscope, doctors can observe ulcers or tumors in the stomach and formulate the best treatment plan accordingly. [0003] Electronic endoscope is a medical electronic optical instrument that can be directly inserted into the body cavity or organ cavity for diagnosis. It uses extremely small electronic imaging components ...

AI Technical Summary

Problems solved by technology

[0006] In order to make up for the shortcomings of the existing technology, when the existing electronic endoscope uses the lighting lens to irradiate the human body organs, due to the fixed focal length of the objective lens, when it penetrates into different positions of the human body, it cannot focus effectively, which eventually leads
