Clamping device for use with an anatomic external fixation device

A clamping device for an external fixation system, comprising:

• a clamp body including a first jaw and a second jaw and defining a first channel configured to accommodate a fixation element along a longitudinal axis of the first channel, the first jaw defining a first opening and the second jaw defining a second opening;
• and
• a locking assembly including a first locking element, a second locking element, a third locking element, and a lever configured to couple to the second locking element, the first locking element including a first end, a second end opposite the first end, and a shaft portion extending from the first end to the second end, the shaft portion sized to pass through the first opening of the first jaw and the second opening of the second jaw, the second opening sized to restrict the first end of the first locking element from passing through the second opening, the first locking element defining a second channel sized to receive a bone pin, the second channel extending within the first locking element from a first channel opening at the first end to a second channel opening at the second end, the locking assembly configured to reduce a distance between the first jaw and the second jaw responsive to rotation of the second locking element relative to the first locking element, the third locking element including a base portion attachable to the first jaw;
• the lever configured to attach to the second locking element and rotate about the second locking element from a first position to a second position to cause the distance between the first jaw and the second jaw to be reduced further while the first end is in contact with the second opening, the lever including a cam wall defined by a first cam radius and a second cam radius greater than the first cam radius such that rotating the lever from the first position to the second position increases a distance between the second locking element and the base portion that is offset by the reduced distance between the first jaw and the second jaw.
