Abstract

The invention relates to a rat spine distracting device, wherein an upright post is installed at one side in the middle of a base, and a fixing support is installed on the upright post; two parallel guiding shafts are installed on the lateral side of the fixing support, and the other ends of the guiding shafts are fixed on a crossbeam; a moving support is movably installed on the guiding shafts, and a screw rod is installed on the moving support; the screw rod is connected with a handle installed on the crossbeam, and the handle is provided with a scale displaying the movement distance of themoving support driven by the screw rod; and distracting claws are installed below the fixing support and the moving support, and are of a fork shape. The invention can be used for well simulating thecondition of spine distraction in a spine operation, and has the advantages of simple and practical structure, convenience for operation, fine stability during the spine distraction, fine experimental repetitiveness, controllable degree of spinal cord injury, capability of accurately determining experimental data and capability of well meeting the requirements for founding an animal model of tractive spinal cord injury.

Description

technical field [0001] The invention relates to an animal injury experiment device, in particular to a rat spinal column stretching device. Background technique [0002] Spinal cord distraction injury is common in spinal trauma or iatrogenic injury in spinal orthopedic surgery and is a serious complication. Therefore, the spinal cord stretch injury caused by excessive stretching of the spine in orthopedic surgery has attracted widespread attention from scholars. How to protect spinal cord tissue, effectively reduce post-injury disability, and promote the reconstruction of injured spinal cord function has always been an important research topic at home and abroad. one of the directions. [0003] Spinal cord injury and its secondary pathophysiological responses can directly lead to nerve function damage, tissue and organ dysfunction, and a very high disability rate. One of the difficult problems in its research is how to establish a quantitatively reproducible animal model t...
