Abstract

The invention discloses an impactor of a spinal cord injury animal model and an operating method of the impactor. The impactor comprises a base, an XY sliding table, a first handle, a second handle, an impact rod, a guide hole, a first impact rod clamp, a second impact rod clamp, a magnetostrictive displacement sensor, a suspending block, a screw sliding table, a connection bar, an arc support anda control box. The arc support, the screw sliding tale and the XY sliding table are arranged on the base, the first impact rod clamp is connected onto the screw sliding table through the connection bar, the magnetostrictive displacement sensor is vertically arranged on the arc support, the second impact rod clamp at the bottom of the magnetostrictive displacement sensor is fixed on the arc support, an experiment subject fixture is fixed on the XY sliding table, and the first impact rod clamp, the second impact rod clamp, the screw sliding table and the magnetostrictive displacement sensor areconnected with the control box through cable connectors. The impactor can effectively avoid secondary impact and allows the descent path of the impact rod to be measured under high precision.

Description

technical field [0001] The invention belongs to the technical field of medicine, and relates to a spinal cord injury animal model striker and an operating method thereof, in particular to a spinal cord injury animal model striker with measurable striking degree and an operating method thereof. Background technique [0002] Spinal cord injury (spinal cord injury, SCI) is a serious trauma, and its incidence is increasing year by year. The treatment and rehabilitation of spinal cord injury is a major problem in today's medical field, because the pathophysiological mechanism after SCI is very complicated, and its Understanding is not enough. In order to better study the mechanism and pathological changes of spinal cord injury and provide evidence for effective treatment, it is of great significance to establish a standard and ideal experimental model. [0003] Clinical similarity, controllability, and reproducibility are often used as criteria for an ideal SCI animal model. Th...
