ELEMENT OF DYNAMIC CONNECTION FOR SYSTEM OF SPINE FIXATION AND SYSTEM OF FIXATION, CONTAINING SUCH ELEMENT Russian patent published in 2009 - IPC A61B17/70 

FIELD: medicine.

SUBSTANCE: group of inventions relates to medicine. Element (10) of connection for spine fixation system intended for connecting of at least two implanted connective nodes, is formed by rod containing flexible part (11) extending at least on one of its ends by means of rigid part (12). Flexible part (11) contains cable (13) surrounded at least partially, by polymer envelope (14). Cable contains at least one elastic strand, coaxial with said envelope (14). Spine fixation system contains at least two implanted connective nodes, joined by means of at least one said element (10). Inventions ensure centering in order to adapt to natural lordosis of spine lumbar part, low invasiveness, at the same time ensuring required functional characteristics of dynamic connection element (flexibility, wear resistance), quick mounting on elements of cable anchorage, fixed on vertebrae.

EFFECT: invention also ensures possibility to undergo extension and/or compression after its mounting on elements of cable anchorage.
