Lateral rod reducer

A lateral rod reducer comprising:

• a body;
• a fixed jaw extending from a distal end of the body, the fixed jaw being configured to couple with a tulip of a pedicle screw;
• a hinged jaw extending from a distal end of the body;
• a linkage mechanism having a distal end pivotably coupled to the hinged jaw;
• and
• a lateral reduction mechanism with
• a lateral threaded ram positioned within a side lumen of the body,
• the linkage mechanism having a proximal end coupled to the distal end of the lateral threaded ram;
• wherein rotation of the lateral threaded ram moves the linkage mechanism forward or backward to rotate the hinged jaw between an open or closed position;
• wherein the hinged jaw is configured to engage a spinal fixation rod in the open position and medially reduce the spinal fixation rod to the tulip in the closed position;
• and
• an axial reduction mechanism with an axial threaded ram positioned within a threaded portion of a central lumen of the body and rotation of the axial threaded ram within the threaded portion lumen moves the axial threaded ram forward or backward axially and to extend axially from the body and apply a load to reduce the spinal fixation rod to a tulip slot in the tulip.

A lateral rod reducer comprising:

• a body having a central lumen and a side lumen;
• an axial reduction mechanism positioned within the central lumen of the body configured to apply an axial force to reduce a spinal fixation rod into a tulip slot of pedicle screw;
• a lateral reduction mechanism positioned within the side lumen of the body configured to apply a lateral force to reduce a spinal fixation rod to the tulip slot of the pedicle screw, the lateral reduction mechanism having:
• a lateral threaded ram positioned within a threaded portion of the side lumen;
• a linkage mechanism having a proximal end coupled to a distal end of the lateral reduction mechanism;
• a fixed jaw extending from a distal end of the body;
• and
• a hinged jaw pivotably coupled to the distal end of the linkage mechanism;
• wherein rotation of the lateral threaded ram is configured to move the linkage mechanism backward to rotate the hinged jaw outward to engage a spinal fixation rod in an open position, then move the linkage mechanism forward to rotate the hinged jaw inward and apply a lateral force to reduce the spinal fixation rod to the tulip in the closed position, the hinged jaw further configured to couple with the tulip in the closed position;
• wherein the axial threaded ram being configured to apply the axial force to reduce the spinal fixation rod to a tulip slot in the tulip.
