The invention discloses a multi-functional animal
craniocerebral injury instrument. The instrument comprises a base, brackets are arranged on the two sides of the middle of the base, and columns are symmetrically arranged on the two sides of the front end of the base; sliding grooves are formed in the inner sides of the columns, the upper and lower ends of the bottom of each sliding groove of thecolumns are movably connected with two driving gears through connecting shafts, and chains are arranged on the outer sides of the two driving gears; driving motors are fixedly connected with the outersides of the columns, and motor shafts of the driving motors are in power connection with the driving gears at the upper ends; rotary frames capable of rotating are arranged in the centers of the tops of the brackets. The multi-functional animal
craniocerebral injury instrument can accurately and continuously control the
impact speed and acquire parameters of actual
impact depth, remaining time and the like and cannot conduct impacting of the large
weight difference. A contusion
injury model can be accurately and repeatedly made, animal death is reduced, and the experiment process is more visible and more controllable; an animal head height measuring device is arranged to conveniently adjust the height of the
craniocerebral injury instrument, and the experiment accuracy is improved.
