The new upgraded precise impactor is a very friendly tool for evaluating traumatic brain injury mechanisms in basic medical research. This system is a popular way to model traumatic brain injury controlled by pneumatic and electrical device, and increased accuracy and reproducibility in brain injury modelling. Moreover, a unique sensor is used to automatically detect the zero reference point at the impact point of the model accurately and reliably before the start of the impact procedure, reducing the tedious process of manual zeroing, it is useful to make accurate and highly repeatable in brain injury modelling. In the experiment, standard cylindrical head hammers of different sizes are available. Parameters such as impact depth, velocity and dwell time can be carefully controlled to ensure that the damage level is accurate. It is an accurate instrument with high efficiency, repeatability and stability that ensures the reproducibility of the damage model.<\/p>\n","protected":false},"excerpt":{"rendered":"
