Model of Traumatic Brain Injury & Spinal Cord Injury  

Neurological injury accounts for around 70% of traffic accident injuries and remains an important factor causing pain, disability and even death. Spinal cord injury (SCI) and traumatic brain injury (TBI) are serious injuries to the nervous system injuries with high disability rate and mortality rate. However, there are currently no effective neuroprotective agents for TBI treatment. In order to further understand the pathophysiology of SCI and TBI and evaluate the neuroprotective effect of drugs, it is necessary to establish suitable animal models that simulate TBI or SCI.

Our Models for TBI / SCI - Controlled Cortical Impact (CCI) Model

Greentech provides controlled cortical impact model to mimic TBI or SCI in humans, which is currently one of the most used models due to high reproducibility.

Induction: spinal cord injury or traumatic brain injury is achieved with a controlled impact device. Subsequently, the skull defect is repaired and the incision is closed.

Advantages: high clinical similarity; high reproducibility; controlled impact strength, depth and duration

Animal Species
