Large and small mouse stereotaxic apparatus fixing structure

Abstract

The invention discloses a large and small mouse stereotaxic apparatus fixing structure, which comprises an operating plate, wherein the operating plate is connected with a fixing column through a regulation mechanism; the fixing column is provided with a tooth fixing mechanism; and the top of the operating plate is fixedly connected with two symmetrical fixing blocks a. The large and small mouse stereotaxic apparatus fixing structure has high regulation accuracy, and in a process that a large and small mouse is fixed, a situation that the teeth bleed or the eardrum is broken due to improper regulation can be avoided. The top of a supporting plate is provided with a magnet a and a magnet b so as to realize an effect that tissues or cloth liners can be conveniently fixed, and a situation that in a process that the large and small mouse receives a test, the large and small mouse suffers from gatism to pollute the supporting plate is avoided. The height of the supporting plate can be improved and reduced according to requirements so as to quickly fix the large and small mouse by an ear rod and a tooth fixing rod, and test efficiency is improved.

Description

technical field [0001] The invention relates to the related fields of medical research and medical equipment, in particular to a fixing structure of a stereotaxic instrument for rats and mice. Background technique [0002] Brain stereotaxic instrument, also known as brain fixation device, uses a three-dimensional coordinate system specified by landmarks or other reference points on the outside of the skull to determine the location of certain subcortical neural structures so that they can be monitored under non-direct exposure. Directed stimulation, destruction, injection of drugs, guided potentials, etc. Animal brain stereotaxic instrument is an important research equipment in the fields of neuroanatomy, neurophysiology, neuropharmacology and neurosurgery. It is used for directional injection, stimulation, destruction, guided potential and other operations on neural structures. It can be used in animal models of cerebral hemorrhage Establishment, Parkinson's disease animal...

Problems solved by technology

[0004] 1. When fixing the large and small mice, the upper teeth of the large and small mice need to be fixed first with the upper jaw clamp, but the slider for installing the upper jaw clamp slides on the operating table, and the fixing needs to be fixed with screws , when fixing the upper teeth of large and small mice, it is necessary to manually push the slider to move on the operating table to adjust the position of the slider, and this way of fixing, the adjustment accuracy is poor, and it will also affect the size of the large and small Rats cause trauma, and even lead to teeth bleeding of mice and rats, affecting the progress of the experiment;

[0005] 2. When using ear sticks to fix the ear canals on both sides of the big and mice, it is also to manually push the ear sticks to move to the head of the big and mice. When the ear sticks touch the ear canals of the big and mice, Screws are used for fixing, but this way of fixing, the adjustment accuracy is poor, and at the same time, the eardrums of the big and mice may be pierced, causing the big and mice to struggle on the console, which affects the progress of the experiment
