Full-angle adjusting and fixing device for high-precision experiment of ophthalmic laboratory mouse

Abstract

The invention discloses a full-angle adjusting and fixing device for a high-precision experiment of an ophthalmic laboratory mouse. The full-angle adjusting and fixing device comprises an X-axis sliding block, an X-axis adjusting plate, a Y-axis sliding block, a Z-axis adjusting device and an experiment table assembly which are sequentially arranged from bottom to top, wherein the Y-axis sliding block is composed of a right-angle sliding block I and a right-angle sliding block II; the right-angle sliding block I and the right-angle sliding block II are arranged on the X-axis adjusting plate and are symmetrically distributed; the Y-axis adjusting plate is further clamped between the X-axis adjusting plate and the Y-axis sliding block; the Z-axis adjusting device comprises a rhombic retractable frame, a vertical fixing rod I, a vertical fixing rod II and a horizontal fixing rod; the bottom of the rhombic retractable frame is arranged on the Y-axis adjusting plate and a fixed platform isarranged at the top of the rhombic retractable frame; the bottoms of the vertical fixing rod I and the vertical fixing rod II are arranged on the Y-axis adjusting plate; the fixed platform, the vertical fixing rod I and the vertical fixing rod II are connected through the horizontal fixing rod; and the experiment table assembly is arranged above the fixed platform.

Description

Technical field: [0001] The invention relates to the technical field of biomedical ophthalmology instruments and equipment, in particular to an all-angle adjusting and fixing device for high-precision experiments on ophthalmic laboratory mice. Background technique: [0002] The eyeball structure and pathophysiological process of mice are similar to those of humans, and they are easy to raise and low in cost. Therefore, mouse eyeballs are widely used as ophthalmic disease models in eye disease inspection, treatment-related ophthalmology teaching, and medical experiments. An important feature of ophthalmology experiments is that most of the inspection or treatment operations are carried out under ophthalmic microscopic magnification instruments, which require high precision. For example, eye examinations such as eye slit lamp microscopy, ultrasound biomicroscopy, anterior segment / fundus photography, optical coherence tomography, fundus fluorescein angiography, or eye treatment...

AI Technical Summary

Problems solved by technology

At present, most of the experiments are carried out by placing the anesthetized mice sideways on the floor-standing test bench in front of the instrument or using a tabletop carton to raise them up. Some existing mouse fixing devices can effectively fix the experimental mice. Some special fixtures for ophthalmology experiments can change the angle of mouse eyeballs within a certain range, but they cannot freely change the tilt angle, rotation, and position movement at the same time
