Rod link reducer

Abstract

Rod link reducer assemblies, systems, and methods thereof. The rod link reducer assembly provides a manipulator rod having a first end, a second end, and an elongate body extending along a body axis between the first end and the second end. A post extends outwardly from the rod. A rod manipulating joint comprise an elongate joint rod extending along a joint rod axis, a first coupling clamp disposed along the joint rod, the first coupling clamp releasably connectable to the post, and a second coupling clamp disposed along the joint rod adjacent to and rotatable about the joint rod relative to the first coupling clamp. The second coupling clamp is releasably connectable to a shaft. A biasing member is adapted to bias the second clamp against the first clamp.

 a manipulator rod having a body axis between a first end and a second end, wherein the second end of the manipulator rod comprises a receiver including a channel configured to receive a rod and an opening in fluid communication with the channel;   a handle attached near the first end of the manipulator rod and adapted to rotate the receiver about the body axis;   a first post extending outwardly from the manipulator rod;   a second post; and   a rod manipulating joint including:
 an elongate joint rod extending along a joint rod axis; 
 a first coupling clamp disposed along the joint rod, the first coupling clamp configured to releasably clamp to the first post; and 
 a second coupling clamp disposed along the joint rod adjacent to and rotatable about the joint rod relative to the first coupling clamp, the second coupling clamp releasably connectable to the second post.

         8 . The rod link reducer assembly according to  claim 5 , wherein the star grind extends around a partial diameter of the first post and/or second post. 
     
     
         9 . The rod link reducer assembly according to  claim 5 , further comprising a biasing member in the form of a clamp, wherein the biasing member includes a lever having a free end and a cam distal from the free end, wherein the biasing member is configured to be rotatably connected to the joint rod. 
     
     
         10 . The rod link reducer assembly according to  claim 9 , wherein the second end comprises a receiver axis extending orthogonally to the body axis. 
     
     
         11 . The rod link reducer assembly according to  claim 1 , further comprising a first biasing member adapted to bias the second clamp against the first clamp. 
     
     
         12 . The rod link reducer assembly according to  claim 1 , wherein an upper surface of the second coupling clamp comprises a star grind. 
     
     
         13 . The rod link reducer assembly according to  claim 1 , the handle configured to be removably attached to the manipulator rod and has a faceted receiver adapted to receive a faceted interface of the first end. 
     
     
         14 . The rod link reducer assembly according to  claim 1 , further comprising a biasing member in the form of a clamp, wherein the biasing member includes a lever having a free end and a cam distal from the free end, wherein the biasing member is configured to be rotatably connected to the joint rod.
