Abstract

The invention discloses an acute spinal cord injury animal model modeling impactor, which is characterized by comprising a bracket, a lever, a guide rail, a probe and a relay device for driving the lever. A support point of the lever is arranged on the bracket; one end of the lever is provided with a sucking disc, the other end is connected with the upper end of the probe; the relay device and the guide rail are both fixed on the bracket along a vertical direction; the relay device is arranged above the sucking disc; the probe is arranged in the guide rail along the vertical direction; a return spring is arranged between the upper end of the guide rail and the upper end of the probe; the relay device comprises a multiple-turn coil and an iron core; the iron core is inserted in the multiple-turn coil; and the terminal of the multiple-turn coil is connected with a controllable current output interface of an external circuit. The impact degree and time of the impactor can be controlled, the impact position is more correct, and the repeatability of the impact operation is strong.

Description

technical field [0001] The invention relates to a blower for modeling acute spinal cord injury animal models. Background technique [0002] Spinal cord injury (spinal cord injury, SCI) has a high disability rate, and there is still no breakthrough in its treatment so far. A reliable SCI model is critical for elucidating its pathophysiological mechanism and evaluating the effect of post-injury interventions. [0003] The animal models of mechanical spinal cord injury mainly include heavy object falling injury model, cutting or suction injury model, pinch injury and compression injury model. The heavy fall injury model is now the most commonly used animal for evaluating management strategies for acute spinal cord injury due to its closer resemblance to human spinal cord injury in terms of physiological response to injury and pathophysiology of secondary injury, coupled with a wealth of published experience One of the models. [0004] Establishing an ideal spinal cord injury...
