Abstract
A transverse fixation device is disclosed. The device includes one or more connecting bodies disposed substantially between two elongate rods. Each connecting body includes a receptacle that is capable of engaging with the two elongate rods. A c-ring comprising an outer surface having a spherical curvature is also included. A third rod may be inserted into the c-ring. A clamp included in the connecting bodies may then be disposed about the c-ring and third rod to allow the connecting bodies to slidingly engage with the third rod.
Claims20
A transverse fixation device comprising:
- a first, second and third elongate rod;
- and
- a one-piece connecting body comprising a receptacle facing outwards towards the first rod and away from the second rod, the connecting body further comprising a clamp;
- wherein the clamp is disposed around the third rod,
- wherein the clamp allows the connecting body to slidingly engage with the third rod, and
- wherein the third rod is laterally offset from the receptacle of the connecting body for accommodating anatomical structural elements.
A transverse fixation device comprising:
- a first, second, and third elongate rod;
- a c-ring having first and second free ends facing each other to define an opening;
- a third elongate rod;
- and
- a one-piece connecting body comprising a receptacle facing outwards towards the first rod and away from the second rod, the connecting body further comprising a clamp;
- wherein the clamp is disposed around the c-ring and the third rod, the clamp having a curved surface corresponding to the outer surface of the c-ring, and
- wherein the third rod is laterally offset from the receptacle of the connecting body for accommodating anatomical structures.
The device of claim 10, further comprising a fastener received by the clamp, wherein the fastener causes the clamp to be clamped around the third rod, thereby locking the third rod relative to the connecting body.
A transverse fixation device, comprising:
- a first, second and third elongate rod;
- a first and a second one-piece connecting body, the first and second connecting bodies each comprising a receptacle facing outwards towards either the first rod or second rod and away from the other of the first rod or second rod, wherein the first connecting body comprises a first clamp disposed around one end of the third elongate rod and the second connecting body comprises a second clamp disposed around an opposite end of the third elongate rod;
- a first set screw capable of securing the first clamp to the third rod;
- and
- a second set screw capable of securing the second clamp to the third rod,
- wherein rotation of the first set screw causes the first clamp to be clamped around the third rod relative to the first connecting body, and
- wherein rotation of the second set screw causes the second clamp to be clamped around the third rod relative to the second connecting body.
