FIELD: medical engineering. SUBSTANCE: special body is made with the aid of anatomic preparation and fixatives. Then procedures of closed introduction are performed with the use of biological dummy and special model. Needlemark is introduced into spinous process in middle sagittal plane by means of vertebra preparation. Fixatives are introduced into safe zones by moving them from sagittal plane first in cranial and then side directions Fixatives are brought in from the rear to the front at angle to sagittal plane. This done, position of fixatives is marked on model. EFFECT: more effective fixative introduction process.
