PEDICLE SCREW FOR INTERVERTEBRAL SUPPORT ELEMENTS |
摘要 |
The pedicle screw ( 1 ) for intervertebral support elements ( 3 ) consists of a shaft ( 10 ) and a head ( 2 ) comprising at least two parts ( 20, 22 ). The head is formed as a securing means for at least one support element ( 3 ). Each support element consists of a piece of a cable-like band ( 31 ) and a cylindrical support body ( 30 ) with an axial lumen ( 31 '' containing the band. The band is securable outside end surfaces ( 32 ) of the support body in the head. The head is formed with a contact surface ( 23 ) via which a pressure stress can be exerted on the support body in the band direction, and indeed using the band and in cooperation with a further pedicle screw. A part ( 20 ) of the head ( 2 ), which is firmly connected to the shaft ( 10 ) at the one end of the latter, contains a base groove ( 21 ) which is oriented transversally to the shaft and into which the part of the band ( 31 ) to be secured or a connecting piece ( 292 ) which contains the band can be introduced during the securing of the support element ( 3 ) by means of a translatory movement in the direction of the shaft and fixed there.
