The M5113 spinal cord injury impactor is a device that utilizes the principle of free fall and consists of several parts such as a firing pin, weight, metal tube, and spinal cord clamp. It is mainly used to create animal spinal cord injury models. The spinal cord impactor precisely controls the impact position and force by selecting weights of different weights and limiting devices, causing varying degrees of damage to the animal's spinal cord. It can create highly repetitive spinal cord injury models without the need for computer software control, and has the characteristics of simple operation, strong practicality, and high cost-effectiveness. Mainly used in neuroscience research to establish experimental models for small animals such as mice, rats, and guinea pigs.
