Optical fiber ear and nose cavity mirror

Abstract

The invention relates to an optical fiber ear and nose cavity mirror which comprises a rigid tube mirror and an eye lens. The rigid tube mirror and the eye lens are coaxially arranged in sequence. The rigid tube mirror comprises a protective tube, an image transmission optical fiber wire and a plurality of light transmission optical fiber wires, wherein a light measuring hole is formed in an outer edge of the protective tube, the image transmission optical fiber wire is used for transmitting an image to the eye lens and is fixedly arranged in the protective tube in a homocentric mode, the light transmission optical fiber wires are used for receiving light rays of peripheral light sources through the light measuring hole, the plurality of light transmission optical fiber wires and the image transmission optical fiber wire are fixedly arranged in the protective tube in parallel and the plurality of light transmission optical fiber wires are evenly distributed around the image transmission optical fiber wire and are separated from the image transmission optical fiber wire. The image transmission optical fiber wire serves as an optical fiber element for transmitting the image, 'zero' thickness performance of an image transmission element is completely used and the plurality of light transmission optical fiber wires are adopted in a matched mode so that the image can be transmitted to the eye lens clearly, image distortion is greatly reduced, structure is simplified and manufacture cost is reduced.

Description

technical field [0001] The invention relates to an ear and nose detection device, in particular to an optical fiber otoloscope. Background technique [0002] At present, in the diagnosis process of ear, nose and throat diseases, the detection equipment usually used is otoloscope. The optical system in the conventional ENT mirror includes a plurality of refractable optical lenses arranged in the protective tube of the rigid tube mirror, through the combination of these optical lenses, the image can be transmitted to the eyepiece in the ENT mirror for observation. However, this existing optical system is not only complicated in structure and serious in image distortion, but also requires high cost. In addition, because it uses multiple optical lenses, it is impossible to make the protective tube very thin (the ear tubes currently on the market The minimum diameter of the rigid tube scope of the rhinoscope is 6mm), which causes inconvenience to the doctor's use and also brings...
