DEVICE FOR CORRECTING AND STABILIZING THORACIC, LUMBAR OR THORACOLUMBAR VERTEBRAL COLUMN SEGMENTS IN SEVERE DEFORMITY CASES Russian patent published in 2007 - IPC A61B17/70 

FIELD: medical engineering.

SUBSTANCE: device has fabricated structure having fixing members arranged one under another and a pair of rods or wires one of which binds the fixing members arranged along a longitudinal lateral face of the fabricated structure and the other one along the other longitudinal lateral face. The pair of rods or wires are connected to each other at least by a pair cross-beams. Each fixing member has lump-shaped body, hook and grasping means. The lump-shaped body rotatable about its longitudinal axis is mounted on the rod or a wire, movable lengthways and fixable in an assumed position. The hook protrudes from the lump-shaped body. Its first contact surface, enabling correction and stabilization process, is formed by the internal side of hook beginning, projecting from the lump-shaped body and bent under it. The second contact surface enabling correction and stabilization process is formed by trailer hook part surface bent upwards. The first and second contact surfaces enabling correction and stabilization process are transiting to each other. Grasping means is sharp-pointed and set in capture position in space between the first and second contact surfaces enabling correction and stabilization process.

EFFECT: reduced risk of traumatic complications.
