The invention relates to a tube pressing-type chronic
nerve root injury model in animal. A method for constructing the model comprises the steps of: wrapping a
silicone tube with a C-shaped cross section on the position 2-3mm above the
dorsal root ganglion of the
nerve root of a rat, wherein the inner
diameter of the
silicone tube is 0.9-1.1mm, the outer
diameter is 1.2-3mm, and the
tube length is 2-4mm. The invention further provides the method for constructing the model and the application of the model. The tube pressing-type chronic
nerve root injury model in animal provided by the invention has the advantages of simple technology and easy duplication, uniform, objective and standard produced pressure, small individual variation for
pathological change, stability, reliability, high
repeatability and convenience for comparison, and is closer to the
pathological conditions of chronic compression caused on the nerve root by the intervertelbral disc or osteophyte, and a compressed model of nerve
root disease which is stable, reliable, easy to standardize and convenient to display effects of treatment factors is provided for operation,
medicine,
acupuncture and
moxibustion and the like in treating chronic nerve root injury.
