Abstract
Connection devices and methods for connecting a rod to a vertebral member. The device may include a receiver mounted to a proximal end of an anchor. The receiver includes a receiving section size to accommodate the rod and adjustable between open and closed orientations. One or more members are mounted to the receiver to adjust the size of the receiving section. In some embodiments, the movable members may be rotated and/or are rotatable to accommodate a rod at different angular positions relative to the anchor.
Claims29
A device to connect a rod with a vertebral member comprising:
- an anchor having a centerline that extends between a distal end and a proximal end;
- and
- offset first and second arms connected to the proximal end and forming a receiving section to receive the rod, a distance between the arms being adjustable between a first orientation having an enlarged distance and a second orientation having a smaller distance, the centerline extending through the receiving section in both the first and second orientations.
A device to connect a rod with a vertebral member comprising:
- an anchor having a distal end and a proximal end;
- and
- first and second members positioned at the proximal end and having arms that form a receiving section, an arm of the first member being aligned with a gap in the second member;
- the first and second members being movably connected to the proximal end to adjust a size of the receiving section between a first orientation having an enlarged size to receive the rod and a second orientation having a reduced size to contain the rod.
A device to connect a rod with a vertebral member comprising:
- an anchor having a distal end and a proximal end;
- a first member connected with the proximal end and having first arms extending outward from a base, the arms being spaced apart with a gap therebetween;
- a second member positioned at the proximal end and having a second arm extending outward, the second member positioned opposite from the first member forming a receiving section therebetween with the second arm aligned with the gap;
- at least one of the first and second members being movable to adjust a size of the receiving section between a first orientation having an enlarged size to receive the rod and a second orientation having a reduced size to contain the rod.
A method of connecting a rod to a vertebral member comprising the steps of:
- spacing apart arms on first and second members that are connected to a proximal end of an anchor that is inserted with the vertebral member;
- inserting the rod into a receiving section formed between the arms of the first and second members;
- moving the arms of the first and second members together with an arm of the first member being aligned with a gap in the second member forming an offset configuration and containing the rod within the receiving section and being aligned with a centerline of the anchor.
