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.
