Document Type and Number:
Japanese Patent JP4444151
Kind Code:
B2
Abstract:
The element has a cylindrical body with two ends and flexible section between the ends. The flexible section is made from two coil springs which are arranged coaxially. The turning (3) of the coil spring (7) runs in a section of the coil spring between the turnings (4) of the other coil springs (8). The coil springs have the same outside diameter and in one level, the center axle of the coil springs (7,8) are of the same cross section of the turnings. The coil springs are turned 180 degrees relative to the other one around their common center axle. An independent claim is included for a bone anchorage element with a shank, a rod-shaped element for connecting two bone anchorage elements, stabilization mechanism, and a method of fabrication of an elastic element.
