A tailbone rocking device for experimental animals and its application

Abstract

The invention relates to an experimental animal caudal vertebra swing device and an application thereof. The device comprises a base, a motor, a rocking bar component, an animal placing platform, a caudal vertebra head end fixing rack and a caudal vertebra tail end fixing rack, wherein the animal placing platform is fixed on the base; the caudal vertebra head end fixing rack is fixed at one end of the animal placing platform; the motor is fixed below the base; one end of the rocking bar component is connected on the motor; the other end of the rocking bar component is fixedly connected with the caudal vertebra tail end fixing rack; the caudal vertebra tail end fixing rack and the caudal vertebra head end fixing rack are arranged at the same height; and the motor drives the caudal vertebra tail end fixing rack to swing through the rocking bar component, so that the experimental animal caudal vertebra with two ends fixed by the caudal vertebra head end fixing rack and the caudal vertebra tail end fixing rack respectively swing. Compared with the prior art, the device can realize dynamic acceleration and swing on an experimental animal tail intervertebral disc to simulate long-time activities or excessive activities, namely overtime and super-amplitude activities of the intervertebral disc, so that influence of different swing effects to the intervertebral disc is observed.

Description

technical field [0001] The invention relates to an auxiliary device for basic medical research, in particular to a tail vertebra swing device for experimental animals and its application. Background technique [0002] In the field of disc degeneration research, there has been debate about the true cause of why discs degenerate. With the progress of the research and the in-depth study of the intervertebral disc, the "wear and tear" theory is more and more generally accepted by the majority of scientific researchers. The "wear and tear" theory is the wear and tear theory of the intervertebral disc. In real life, long-term or excessive activities of the intervertebral disc, that is, overtime and over-range activities, often cause a series of clinical symptoms. However, do these activities lead to changes in the intervertebral disc? Or degeneration? There is currently no good animal model available for research. [0003] Therefore, a device that can realize long-term activity...
