Abstract

The invention discloses a diffuse axonal injury causing device and a using method thereof, and belongs to the field of traumatic neurosurgery. The problems that an existing animal (mouse) diffuse axonal injury causing experimental device cannot achieve diffuse axonal injury of animals (mice) caused by instantaneous angular acceleration and linear acceleration at the same time, and cannot simulate various brain injury conditions are solved. The diffuse axonal injury causing device comprises a base, a power system and an experimental platform, the experiment platform is composed of a rotating mechanism and a sliding and toothed plate mechanism. The rotating mechanism is composed of an inner gear ring, a gear, a connecting shaft, four animal placing tables and animal placing table supporting seats; the sliding and toothed plate mechanism is composed of two sliding grooves, a fixed toothed plate, a pushing toothed plate and a fixing block. The power system is composed of an electric cylinder, an ejection cylinder and a guide rod.

Description

technical field [0001] The invention belongs to the field of traumatic neurosurgery, and in particular relates to a diffuse axonal injury injury device and a method for using the same. Background technique [0002] Brain injury mainly includes traumatic brain injury and ischemic brain injury, with high disability and fatality rate. Diffuse axonal injury (DAI) is caused by the fact that the brain is subjected to linear velocity or rotational acceleration, causing shearing within the brain tissue, and it is generally believed that rotational acceleration is more likely to be caused than linear acceleration. The diffuse axonal injury in clinical patients is mostly caused by the simultaneous instantaneous angular and linear acceleration of the skull. The existing devices for replicating axonal injury are relatively simple in function, and can only realize rotational acceleration or linear acceleration motion, and cannot realize the most realistic model of axonal injury, and the...
