摘要:
A positionable clip is provided that is engageable on a spinal rod to capture a rod-borne component in a variable position on the rod. In one embodiment, the positionable clip includes a pair of clamping members, each including a pair of opposed arms configured for engaging the rod therebetween. A biasing hinge biases the arms together to grip the rod with sufficient force to maintain the position of the clip on the rod during manipulation of the rod. A bar connects the two clamping members to define a receiving space to receive a component that is disposed on the spinal rod. In one aspect, the bar includes a pressure surface such that a force applied to the pressure surface will cause the arms of the clamping members to displace apart to disengage from the spinal rod. The clip is configured so that this force can be applied by the component captured by the positional clip as the component is itself tightened onto the spinal rod.
