method for modelling in experiment of local dosed craniocerebral trauma of cerebellal hemisphere in rats

摘要

A method for modelling in experiment of local dosed craniocerebral trauma of cerebellal hemisphere in rats representing a method for modelling of an experimental craniocerebral trauma. A rat skull is fixed in a device and impact force is measured measure by means of 2 pairs of strain gauges. After processing of operational wound with antiseptic solution the opening of skin-hypodermical- aponeurotic flap is carried out in the occipital area. In a projection of one of the cortax cerebellal hemispheres a cutter aperture is imposed. Into scull aperture a special core is entered for dosed mechanical trauma. By means of spring striker an injuring impact is delivered by dosed force of its spring tension directly on a surface of solid brain envelope of cerebellal hemispheres.
