CONNECTION SYSTEM BETWEEN A SPINAL ROD AND A TRANSVERSE BAR

摘要

The invention relates to a connection system that is disposed between a spinal osteosynthesis rod (2) and a transverse bar (4). The inventive system is designed to comprise a passage (45) for the transverse bar (4) which is intended to exert a force on two clamping jaws (5, 6), said jaws being articulated in such a way that they move together when the locking element (48) is being tightened. Said system comprises a return spring (20) which acts upon the clamping jaws, moving them towards one another independently of the transverse bar. In this way, the clamping jaws (5, 6) grip the osteosynthesis rod and ensure that the connection system is firmly mounted to the rod.
