Abstract
A system for connecting a spinal osteosynthesis rod and a crossbar include a passage for receiving the corssbar and hinge mounted jaws for clamping the rod. A locking device biases the crossbar against the jaws. A return spring pulls the jaws relatively close to one another independently of the crossbar such that the jaws may clamp the osteosynthesis rod to ensure a stable mounting of the connection system to the osteosynthesis rod.
Claims9
A system for connecting a spinal osteosynthesis rod and a crossbar, the system comprising:
- a support having a channel for receiving a crossbar therein;
- jaws hingedly mounted to the support by a common hinge pin for receiving an osteosynthesis rod therebetween;
- a return spring mounted so as to bias the jaws closer to one another independently of the crossbar, wherein the jaws clamp the osteosynthesis rod for ensuring a stable mounting of the connection system onto the osteosynthesis rod;
- and
- a locking device operable with the support for biasing the crossbar against the jaws for clamping the rod therewith.
