摘要：
A useful model is a device for simulating stereotaxic neurosurgical interventions, which belongs to the field of medical technology in the field of neurosurgery and can be used for non-contact assessment of the accuracy of aiming a stereotaxic instrument at target targets, depending on the location of the sensors of the neuronavigation system. The device consists of a phantom head module and a module stereovision. The "phantom head" module is a spherical layer with markers of the neuronavigation system, removable target targets contrasting for computed tomography, a central mark, and a removable cover. On the surface of the "phantom head" module and on the cover there are holes located in a spherical coordinate system with the given parameters of azimuth and zenith angles. The holes and the central mark make it possible to determine the location of the sensors of the neuronavigation system. The stereo vision module in the form of a bracket for mounting digital cameras in a stereopair is a measuring device connected to a computer and allowing contactless assessment of the accuracy of aiming a stereotaxic instrument on a target by comparing the coordinates of a removable target and the coordinates of the instrument tip. utility model is to provide the following capabilities: - modularity of the device, allows you to combine the functions of modeling target targets and non-contact assessment of the accuracy of pointing stereotaxic instrument； - implementation of removable target targets, which increases the objectivity and accuracy of the study； - determination of the influence of the spatial arrangement of sensors of the neuronavigation system on the magnitude of the error aiming the stereotaxic instrument at the target.Полезная модель - устройство для моделирования стереотаксических нейрохирургических вмешательств, которое относится к сфере медицинской техники в области нейрохирургии и может использоваться для бесконтактной оценки точности наведения стереотаксическог
