MIS multi-level compressor / distractor

A compressor/distractor instrument comprising:

• a compressor/distractor device having:
• a ratcheting mechanism having a ratchet configured to move in a linear direction on a slide rail and
• right and left pivoting arms coupled to screw extenders, the left pivoting arm being coupled to the slide rail and the right pivoting arm being coupled to the ratchet, each pivoting arm being coupled to a threaded shaft and nut, the pivoting arms are configured to move in an angular direction to change an angle between the pivoting arms to allow tilting of the screw extenders for lordosis or kyphosis compression or distraction motion;
• and
• compressor/distractor support tubes coupled to the right and left pivoting arms configured to fit within the screw extenders to provide bending support during compression or distraction of vertebrae;
• wherein the compressor/distractor device and the compressor/distractor support tubes used with a screw extender system for movement of vertebrae in two directions, the ratchet provides movement on the slide rail in the linear direction for compression or distraction of the vertebrae, and the right and left pivoting arms travel up or down the threaded shafts by rotating the nuts to change the angular direction for lordosis or kyphosis of the vertebrae.
