Bone anchor based retractor/distractor

A retractor/distractor assembly comprising:

• a main body configured with first and second pivot points;
• a unitary left stabilizing arm pivotably connected to the first pivot point, the left stabilizing arm having a proximal end spaced apart from a distal end;
• a first blade including a first attachment pin designed to engage an upper blade opening at the proximal end of the left stabilizing arm, the first blade defining a pathway extending between the upper blade opening and a lower end aperture along opposite sides of the blade;
• a first wire with a first end extending through the pathway of the first blade, forming a hoop at the lower end aperture, the hoop being adjustable in diameter to releasably secure a bone screw;
• a unitary right stabilizing arm pivotably connected to the second pivot point, the right stabilizing arm having a proximal end spaced apart from a distal end;
• a second blade including a second attachment pin designed to engage an upper blade opening at the proximal end of the right stabilizing arm, the second blade defining a pathway extending between the upper blade opening and a lower end aperture along opposite sides of the blade;
• a second wire with a first end extending through the pathway of the second blade, forming a hoop at the lower end aperture, the hoop being adjustable in diameter to releasably secure a bone screw;
• a retraction blade fixed to the main body at a position between the first and second blades;
• a threaded rod connecting the distal ends of the left and right stabilizing arms, the rod having a first end rotatably secured to the distal end of the right stabilizing arm and a second end rotatably secured to the distal end of the left stabilizing arm;
• wherein the rod facilitates spacing adjustment between the distal ends of the left and right stabilizing arms about the first and second pivot points on the main body, enabling reciprocal spacing adjustment of the first and second blades.
