SELF-DISENGAGING DEVICE FOR RIB DISTRACTOR

摘要

The invention concerns a distraction device (4) for controlling the development of the deformation of a child's trunk during growth easily implantable into the human body and comprising rods (35, 36) coupled to the bones and mounted on central adjusting means (300) provided with a small hole (312) for engaging a small tool designed to adjust the distance separating the bone coupling means, said device (4) including a miniature casing (410) enabling the rods (35 and 36) to be translated in the direction of growth via a toothed wheel (311), said means being combined with an assembly of means: non-return catch (37), elastomer block (373), rigid cage (374) which enable the device (4) to be disengaged, tensioned and locked in one direction, while allowing growth to be monitored.
