Multi-functional animal craniocerebral injury instrument

Abstract

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.

Description

technical field [0001] The invention relates to a craniocerebral injury instrument, in particular to a multifunctional animal craniocerebral injury instrument. Background technique [0002] Coma is a clinical problem that needs to be solved urgently, and the research on the mechanism and treatment of coma is a hot spot and is very urgent. However, the coma model of animals has not yet been fully realized, and even if the animal is induced into a coma state using existing devices, the duration of coma is very short. On the one hand, it is related to the fact that the evaluation criteria for animal coma have not been completely unified. On the other hand, it is also the most critical reason. The modeling tools for realizing animal coma on the market are not standardized, the operation is complicated, and the repeatability is poor. Contents of the invention [0003] In order to solve the above problems, the invention discloses a multifunctional animal craniocerebral injury i...
