M5110 Craniocerebral injury impactor

       The M5110 traumatic brain injury impactor is a device that utilizes the principle of free fall and consists of a standard brain stereotaxic device, a free fall impactor, weights, and a firing pin. It is mainly used to create animal models of traumatic brain injury.
The device uses a brain locator to fix the animal's head so that it does not undergo any relative movement. The 3D manipulator arm is moved to accurately locate the impact site. Then, using the principle of free fall, different weights and limit devices are selected to precisely control the impact position and force, causing varying degrees of damage to the animal's skull and brain. It does not require computer software control to create highly repetitive brain injury models, 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.
