Transpedicular spinal stabilizer

摘要

The transpedicular stabilizer according to the invention characterized in that stiffness related to the shift of the external sleeve 4 in relation to the pin 6 varies in the direction of planes /A/ and /B/ and is limited by the gap /L3/ and the elastic sleeve /5/, whereas between internal planes /A/ of the external sleeve /4/ and the pin /6/ a gap /L1/ is created with a size within the range of 0.05-0.2 of the width /a/ of the insert /2/, and between surfaces of the external sleeve /4/ and the pin /6/ there is a gap /L2/ > 2/L1/ and a gap /L3/ > width / a / of the insert /2/.
