Product Details
XR203 traumatic brain injury impactor
A free fall brain injury model hitter made according to the principle of free fall, with the main body used for the production of animal brain injury models. The free fall brain injury model impactor consists of four parts: a firing pin, a weight, a metal tube, and a brain locator. The diameter of the striker is 4.5mm, with a height of 20mm. The striking rod weighs 40 grams and 20 grams respectively, and the metal sleeve has a height of 30cm.
Technical indicators
1. X, Y, and Z axes can be manually adjusted freely
2. Hammer diameter 4.5mm
3. Metal tube height 30mm
4. Strike sticks weigh 40 grams and 20 grams respectively
5. Metal sleeve height 30cm
6. Applicable animals: mice, rats, guinea pigs, rabbits, cats, dogs, etc
[Example of Use]
Fix the rat's head and limbs in a prone position, then cut open the scalp from front to back along the midline, and extend the incision back to the left at a 45 degree angle to form a triangular skin flap. Open the skin flap towards the head, peel off the periosteum, and fully expose the left skull. Using the left skull orbital depression as a support point, use a needle holder to bite open a small piece of skull, expose the dura mater, and expand it backwards into a circular bone window with a diameter of 6mm in the left parietal bone, paying attention to protecting the dura mater.
Place the head end of the impact rod outside the dura mater of the bone window, with a vertical metal sheath. Use a 40g impact rod to freely drop the impact needle from a height of 20cm along the outer metal sheath, with a drop force of 4 × 20cm · g, causing local cerebral contusion and laceration in the left hemisphere of the rat brain.
