Abstract
The present invention relates to a vertebral fixing system adapted to be mounted on a vertebra of the spine to connect it to a rod. The fixing system comprises: a connecting part adapted to face the rib and/or the transverse process and to be connected to the rod; an elongate flexible ligature adapted to connect together the connecting part and at least one rib and/or one transverse process; and an adjustable locking screw fastened to the connecting part and adapted to fix simultaneously in position the connecting part relative to the rod and at least one portion of the ligature relative to the connecting part, so as to prevent relative displacement of the rod and the vertebra in opposite directions.
Claims8
A vertebral fixing system comprising:
- a spinal rod;
- a connecting part including a first longitudinal member and a second longitudinal member moveable relative to each other between a first position and a second position, the first longitudinal member and the second longitudinal member configured to capture the spinal rod when in the second position;
- a ligature having a first end directly attached to the connecting part and a second end opposite the first end, at least one of the first longitudinal member and the second longitudinal member having an orifice to receive the second end of the ligature therethrough to define a loop between the first end and the second end of the ligature, the loop extending from the connecting part and being adjustable in size when the first longitudinal member and the second longitudinal member are in the first position, wherein the first longitudinal member and the second longitudinal member are joined by a hinge for movement between the first position and the second position, wherein the hinge includes a pivot pin rotatably connecting a first end of the first longitudinal member and a first end of the second longitudinal member, and wherein the first end of the ligature is ligated around the pivot pin;
- and
- a lock to secure the first longitudinal member and the second longitudinal member in the second position with the rod captured therebetween, the loop being fixed in size when the first longitudinal member and the second longitudinal member are secured in the second position with the rod therebetween.
