68099Ⅱ, the new upgraded precise impactor is a very friendly tool for evaluate traumatic brain injury mechanisms in basic medical research. This system is a popular way to make a traumatic brain injury modeling, which is controlled by pneumatic and electric device, and increased accuracy and reproducibility in brain injury modeling. In addition, a unique sensor is used to automatically detect the zero-interface reference point at the impact point of the model accurately and reliably before the start of the impact procedure, thus reducing the tedious process of manual zeroing, it is helpful to make precise and highly repeatable in brain injury modeling. In the experiment, the standard cylindrical head hammers with different size are available. The parameters such as impact depth, velocity and dwell time could be precisely controlled to ensurethat the damage level to be accurate. It is an accurate tool with high efficiency, repeatability and stability, ensuring the reproducibility of the damage model .
