Abstract
A clamping device for an external fixation system includes a post component having a yaw axis, a first clamp secured to the post component and rotatable about the yaw axis, and a second clamp secured to the post component and rotatable about the yaw axis relative to the first clamp. The device includes a tightening component configured in a manner that an action of tightening the tightening component simultaneously locks both the first and second clamps in a gripping arrangement and substantially eliminates their relative rotation about the yaw axis. Interdigitating components can be spaced apart by high spring rate biasing elements that so as to allow for smooth adjustment of the clamping device components relative to each other until the appropriate position is achieved and until after a sufficiently high clamping load has been applied.
