Estimating the term…
A clamping device engages an external fixation rod for use in bone fracture surgery includes an upper housing including a ratcheting mechanism, a lower housing including an upper jaw and a lower jaw that engages an external fixation rod. When the upper housing is turned in a clockwise motion relative to the lower housing, the jaws are drawn towards one another until opposed by a predetermined force. Engaging an action pin in the upper housing and turning the upper housing in a clockwise motion can overcome the predetermined force, and engaging an action pin in the upper housing and turning the upper housing in a counterclockwise motion can release engagement to an external fixation rod.
A clamping device configured to engage an external fixation rod for use in bone fracture surgery comprising:
The clamping device of clam 6, further comprising a ratchet pin that engages gears on an outer drive washer, wherein the outer drive washer is engaged to the slip cam washer, wherein counterclockwise rotation of the upper housing results in a ratchet action of the pin along outer drive washer gears that does not result in turning the drive screw or drawing the jaws toward one another.
