Spinal cord injury impactor precise in positioning and adjustable in strike force

Abstract

The invention relates to a spinal cord injury impactor precise in positioning and adjustable in strike force. The impactor comprises a base, a support and a striker, a limiting stopper connecting mechanism and an electromagnetic induction device which can slide up and down along a vertical bar are installed on the vertical bar of the support, a striker motion limiting stopper is arranged on the limiting stopper connecting mechanism and can be driven to rotate around the central axis of the vertical bar and rotate around the horizontal shaft perpendicular to the vertical bar, a protruding part is arranged at the upper end of the striker, the striker motion limiting stopper is provided with a motion limiting rail used for penetrating through the striker so as to guide the motion track of the striker and clamp the protruding part of the upper end of the striker, the falling height of the striker is limited, the electromagnetic induction device is arranged on the upper side of the limiting stopper connecting mechanism and can rotate around the central axis of the vertical bar, and when the electromagnetic induction device is energized, the protruding part of the upper end of the striker which is lifted is attracted. The impactor is high in striking accuracy, good in regulation, high in repeatability, simple in structure and low in manufacturing cost.

Description

technical field [0001] The invention relates to the technical field of spinal cord injury model modeling, in particular to a spinal cord injury striker with precise positioning and adjustable strike force. Background technique [0002] Spinal cord injury (SCI) is a serious trauma with a high disability rate, but its treatment is still a major problem in the medical field. The reason is that the pathophysiological mechanism of SCI is very complicated. Its understanding is not deep and comprehensive enough. Establishing a standard and reliable SCI model is a prerequisite for SCI research and treatment, and is of great significance for the progress of research. [0003] There are many models of spinal cord injury, among which the heavy object falling impact model is one of the most commonly used animal models of acute spinal cord injury because it is closer to human spinal cord injury in terms of physiological response to injury and pathophysiology of secondary injury. The mo...

Problems solved by technology

The most commonly used animal spinal cord injury percussion devices for establishing spinal cord injury models in the world today are NYU (New York University) collider and IH percussion device. The former has the problem of two strikes, while the latter is complicated and expensive

Many domestic research institutions and scientific researchers have also improved the spinal cord injury percussion device and proposed many improved devices, but most of these devices have problems such as poor repeatability, poor control, or complex structure and high cost.
