An electronic endoscope for medical imaging

Abstract

The invention relates to the technical field of medical imaging equipment, and discloses an electronic endoscope for medical imaging, which includes a coiled tube channel, a negative pressure mechanism is fixedly installed on the top of one side of the coiled tube channel, and an illumination device is fixedly installed in the middle of the inner cavity of the coiled tube channel. Optical fiber, a CCD video line is provided between the inner wall of the snake tube channel and the outer surface of the lighting fiber optic, and an air flow line is installed between the lighting fiber optic and the CCD video line and at the top of the inner cavity of the snake tube channel, and the right side of the outside of the coil tube channel is fixedly installed There is an objective lens, and one side of the objective lens is fixedly equipped with an illumination lens. The electronic endoscope for medical image imaging, through the setting of the negative pressure mechanism and the objective lens, the negative pressure mechanism can be used to adjust the angle of the objective lens, so as to increase its ability to capture light, and then more light information can be captured. Passed to the CCD, compared with the existing endoscope, it can effectively increase the light information captured by it, and improve the definition of the endoscope imaging.

Description

Technical field [0001] Technical Field The present invention relates to a medical imaging device, particularly to a medical image imaging electronic endoscope. Background technique [0002] An electronic endoscope is inserted directly into a body cavity or lumen of an organ electronic optical instruments for medical diagnosis utilizing an electronic imaging device extremely small size, it will be observed in an image signal supplied to the image processor, after directly observe the image information for physicians and diagnostic monitor. [0003] However, the conventional electronic endoscope when irradiated with illumination lens body dirty, due to the dirty surface is rough, resulting in diffuse light reflection phenomenon is more serious, many rays are depleted in the course of the diffuse reflection, Further the objective lens can not be captured by the lens, so that less light information captured, resulting in poor resolution CCD imaging, can not meet the diagnostic needs ...

AI Technical Summary

Problems solved by technology

[0005] The invention provides an electronic endoscope for medical image imaging, which has the advantages of strong light capture ability, clear imaging, high diagnosis efficiency, and reduces the pain and discomfort of patients during diagnosis, and solves the problem of existing problems. When the electronic endoscope uses the lighting lens to irradiate the human organs, because the surface of the organs is relatively rough, the diffuse reflection of the light is more serious, and a lot of light is exhausted in the process of diffuse reflection, which cannot be detected The objective lens captures less light information, which eventually leads to poor imaging clarity of the CCD and cannot meet the doctor's diagnostic needs. It is necessary to use the endoscope to enter the human body for observation many times, which is relatively inefficient. Problems that increase pain and discomfort for patients at the time of diagnosis
