The invention relates to the field of animal experiment testing devices, in particular to an adjustable rat
intervertebral disc degeneration modeling device which comprises a base body, a first
kirschner wire used for being fixed to the
vertebra of a
rat tail is arranged on the base body in a penetrating mode, a guide
assembly is installed on the base body, and two
kirschner wire fixing blocks are movably installed on the guide
assembly; and a second
kirschner wire is arranged on the two kirschner wire fixing blocks in a penetrating manner. When the
Kirschner wire fixing block is driven by the adjusting
assembly to perform displacement change, not only can the second
Kirschner wire generate a compression function, but also the second
Kirschner wire can realize a bending function, so that the bending compression or stretching of a rat
caudal vertebra at a specific angle can be realized, and the bending compression condition of an
intervertebral disc can be really simulated; meanwhile, the compression and
bending force of the second kirschner wire can be freely adjusted, so that the deviation between an experimental result and an actual
physiological condition can be remarkably reduced through the adjusting mode, and the real mechanism of occurrence and development of diseases can be accurately reflected.
