METHOD FOR DIRECTING STEREOTACTIC INSTRUMENT TO A TARGET POINT Russian patent published in 1999 - IPC

FIELD: medical engineering. SUBSTANCE: device has fixing marks on maxillary alveolar process to carry out tomographic examination of patient head provided with the marks determining mark and target point coordinates in the tomograph coordinates reference system. Marks and target point are mapped and target point coordinates are determined by superimposing marks coordinates and the corresponding intracerebral space model points coordinates. Guiding unit is installed in the intracerebral space model. The unit is applied for guiding instrument to the target point. The unit is then transferred to the patient head and the instrument is focused over intracerebral target point through a milled hole. EFFECT: usability with any type of tomograph; wide range of functional applications. 4 dwg
