Description
Technical Field
The invention belongs to the field of animal raising devices, and particularly relates to a fixing device for fixing a reptile to enable the reptile to freely move in an upright state.
Background
Disc degeneration (intervertebral disc degeneration, IVDD) is a prerequisite and fundamental pathological process of a series of spinal degenerative diseases, and is clinically manifested by neck and shoulder pain, lumbago and leg pain, etc., and the nerve root and spinal cord related to patients are stressed and produce a series of corresponding symptoms. At present, the etiology and pathogenesis of the IVDD are not completely elucidated, and a reliable animal model is established through researching an intervertebral disc degeneration variable model, so that a good research object and experimental carrier can be provided for researching the etiology and pathogenesis of the IVDD. Although many studies have been made to establish an intervertebral disc degeneration model by various methods including a spontaneous intervertebral disc degeneration model, an intervertebral disc degeneration model caused by stress change, an intervertebral disc degeneration model caused by spinal instability, a chemically prepared animal model, a genetically modified or knocked-out prepared animal model, and a surgically damaged animal model, none of the well-recognized and reliable modeling methods have been widely used so far.
At present, more common animal species used for constructing the intervertebral disc degeneration animal model are mice, rabbits, sheep, dogs, pigs and the like, and the species have common characteristics, namely, all the species are reptiles, the physiological structure of the spinal column of the species is opposite to that of an upright human, and after the animal model is built, the life habit of the reptiles is an important factor influencing experimental results; in addition, the monkey and baboon with similar relativity to human are ideal model animals, can walk upright on two feet, have similar spine structure and similar biomechanical factors carried by the spine to human, thus building a model of monkey intervertebral disc degeneration for researching pathological processes of human intervertebral disc degeneration is the most true and reliable, but has the related problems of rare sources, high price, inconvenient feeding, ethics and the like, thereby limiting the application of the model animals.
For the above reasons, the following should be satisfied in selecting, preparing a model of intervertebral disc degeneration, the species: (1) The process of intervertebral disc degeneration of model animals and human has similarity and comparability; (2) good repeatability; (3) has easy operability and economy. Therefore, if a reptile can be changed to an upright life habit, such an experimental animal becomes the first choice for building up an intervertebral disc degeneration model. However, large mammals such as pigs, dogs and sheep have the defects of high price and inconvenient feeding, so that the animals are not widely applied to the preparation of intervertebral disc degeneration animal models; the experimental animals widely used for preparing the intervertebral disc degeneration animal model in the experimental research of the IVDD are rats and white rabbits.
To overcome the defects of the two animals in terms of anatomical structures and biomechanics, a learner adopts an artificial method to force the two animals to stand, such as cutting the upper limbs of rats to establish a bipedal upright animal model; the white rabbits are placed in a specially-made cylinder to keep a straight three-dimensional position and are longitudinally pressurized to build an animal model, and the vertical animal model is built by adopting corresponding measures, so that the pathological mechanism of the pathological intervertebral discs can be further researched by the stimulation of mechanical factors. However, the method is more forgiving to experimental animals and is not beneficial to popularization.
