Anatomic external fixation device

Abstract

A clamping device for an external fixation system includes a clamp body including, a first jaw and a second jaw, wherein the first jaw and the second jaw form a groove configured to receive an external fixation component and a bore configured to receive a bone pin. The clamping device includes a locking assembly coupled to the clamp body and configured to change state between at least an unlocked state and a locked state, wherein the external fixation component is configured to translate within the groove and the bone pin is configured to translate within the bore when the locking assembly is in the unlocked state, and the first jaw and the second jaw restrict movement of the external fixation component within the groove and the bore restricts the bone pin from translating within the bore when the locking assembly is in the locked state.

         3 . The clamping device of  claim 1 , wherein the first jaw and the second jaw define a slot extending between a first surface of the first jaw and a second surface of the second jaw and in communication with the groove, wherein the bore extends through the slot. 
     
     
         4 . The clamping device of  claim 2 , wherein changing the locking assembly from the unlocked state to the locked state causes the first jaw to move closer to the second jaw to secure the external fixation component within the groove and the shaft to compress around the bone pin to secure the bone pin within the bore. 
     
     
         5 . The clamping device of  claim 2 , wherein changing the locking assembly from the unlocked state to the locked state simultaneously causes the first jaw to move closer to the second jaw to secure the external fixation component within the groove and the shaft to compress around the bone pin to secure the bone pin within the bore. 
     
     
         6 . The clamping device of  claim 2 , wherein the locking assembly further includes a second locking component positioned outside of the bore and including a second engagement feature, wherein the first locking component includes a first engagement configured to engage with the second engagement feature such that the first locking component is coupled to the second locking component. 
     
     
         7 . The clamping device of  claim 2 , wherein the first locking component includes a protrusion and the clamp body includes recess configured to receive the protrusion to prevent rotation of the first locking component within the clamp body. 
     
     
         8 . The clamping device of  claim 1 , wherein the clamp body further includes an insert positioned within the clamp body such that a portion of the insert receives the external fixation component to restrict movement of the external fixation component when the locking assembly is in the locked state. 
     
     
         9 . An external fixator system comprising:
 an external fixation component extending between a first end and a second end;   a bone pin coupled to the external fixation component; and   a clamping device including:
 a clamp body having a first jaw and a second jaw, wherein the first jaw and the second jaw define a groove extending along a first axis and configured to receive the external fixation component, and a bore extending along a second axis through the clamp body, wherein the first axis is perpendicular to the second axis; and 
 a locking assembly configured to receive the bone pin, wherein the locking assembly includes comprises a first locking component including a shaft configured to be received within the bore and configured to receive the bone pin, wherein the locking assembly is configured to change state between at least an unlocked state and a locked state, wherein
 the external fixation component is configured to translate within the groove and the bore does not restrict the bone pin from translating within the bore while the locking assembly is in the unlocked state; and 
 the first jaw and the second jaw restrict movement of the external fixation component within the groove and the bore restricts the bone pin from translating within the bore while the locking assembly is in the locked state. 
 
   
     
     
         10 . The clamping device of  claim 9 , wherein changing the locking assembly from the unlocked state to the locked state causes the first jaw to move closer to the second jaw to secure the external fixation component within the groove and the shaft to compress around the bone pin to secure the bone pin within the bore. 
     
     
         11 . The clamping device of  claim 9 , wherein changing the locking assembly from the unlocked state to the locked state simultaneously causes the first jaw to move closer to the second jaw to secure the external fixation component within the groove and the shaft to compress around the bone pin to secure the bone pin within the bore. 
     
     
         12 . The clamping device of  claim 9 , wherein the locking assembly further includes a second locking component positioned outside of the bore and including a second engagement feature, wherein the first locking component includes a first engagement configured to engage with the second engagement feature such that the first locking component is coupled to the second locking component. 
     
     
         13 . The clamping device of  claim 9 , wherein the first locking component includes a protrusion and the clamp body includes recess configured to receive the protrusion to prevent rotation of the first locking component within the clamp body. 
     
     
         14 . The clamping device of  claim 9 , wherein the first locking component includes one of radial interdigitation or serration. 
     
     
         15 . A method of fixating a bone fixator system, the bone fixator system comprising an external fixation component, the method comprising:

   providing the bone pin through the first locking component and into the at least one target bone; and   tightening the locking assembly, wherein tightening the locking assembly causes the first jaw and the second jaw to restrict movement of the external fixation component within the groove and causes the first locking component to restrict the bone pin from translating within the bore.   
     
     
         16 . The method of  claim 15 , wherein tightening the locking assembly simultaneously causes the first jaw to move closer to the second jaw to secure the external fixation component within the groove and the shaft to compress around the bone pin to secure the bone pin within the bore. 
     
     
         17 .
