Abstract

The invention discloses a mouse fixing device used for high-resolution detection experiments in ophthalmology. Including ear fixing device, mouth fixing device, holder main body and rotary translation platform; holder main body includes bottom plate, cylindrical part, isosceles trapezoidal plate and protruding column; ear fixing device includes two zigzag curved The ear bar and the front side of the isosceles trapezoidal plate are installed and connected with a mouth fixing device. The mouth fixing device includes a mouthpiece main body, a mouth clip, an adjusting screw, a position control spring, and a fixing bolt. The invention reduces the volume of the fixing device near the head of the mouse, can effectively fix the mouse, eliminates shaking, and enables short-focus detection to work normally near the mouse's eyes without being hindered by fixing, ensuring near Distance and multi-directional detection of flexibility and stability of mouse eyes.

Description

technical field [0001] The present invention relates to the technical field of biomedical ophthalmology instruments and equipment, and more specifically relates to a mouse fixation device for ophthalmology high-resolution detection experiments, especially short-distance, multi-angle, high-resolution detection under the condition of using a short-focus optical system. Ratio mouse eye detection experiment. [0002] technical background [0003] Because the eyeball structure of mice is similar to that of humans, and they are easy to raise and low in cost, they are more and more widely used in ophthalmic medical experiments. In the course of the experiment, in order to stably observe the mouse's cornea, retina and other ocular structures from multiple angles, an adjustable fixator is needed, which can fix the head of the anesthetized mouse and adjust the head position of the mouse. Make flexible adjustments. [0004] For some ophthalmic quantitative detection techniques, such a...
