RODS FROM POLYMER FOR APPLICATION ON SPINE Russian patent published in 2012 - IPC A61B17/70 

FIELD: medicine.

SUBSTANCE: group of inventions relates to medicine. Elongated element for spine stabilisation in accordance with the first version contain arc-shaped main unit, first and second tips. Arc-shaped main unit has first end, second end and central part, passing in fact between first end and second end and having elongated section, whose height is larger than its width. First end has in fact round surface and first hole for tip, passing through it. Second end has in fact round surface and second hole for tip, passing through it. Arc-shaped main unit is formed from polymer of medical application and is hardened in its final shape. First tip has first projection, made with possibility of interaction with first hole for tip and has means of interaction with instrument, located opposite first projection and made with possibility of interaction with surgical instrument. Second tip has second projection, made with possibility of interaction with second hole for tip, and rounded end, located opposite second projection. Elongated element for spine stabilisation in accordance with the second version contains arc-shaped main unit and tip. Arc-shaped main unit has first end, second end and central part, passing in fact between first end and second end and having elongated section, whose height is larger than its width. First end has a hollow, made with possibility of interaction with surgical instrument. Second end has in fact round surface and hole for tip, passing through it. First and second ends and central part of arc-shaped main unit are formed in one piece from polymer of medical application and are hardened in their final shape. Tip has projection, adapted for conjugation with hole for tip and rounded end, located opposite projection.

EFFECT: inventions ensure biological compatibility, strength, flexibility, wear resistance.
