Abstract

The invention relates to a position supporter with a tube-shape body (4), especially for vertebrae or intervertebral disk, having a plurality of through holes or openings (9) growing together with the adjacent tissue. The position supporter includes at least one second tube-shape body (2, 3) with the through holes and the openings (9), which is at least partly positioned in the first tube-shape body. The first tube-shape body and the second tube-shape body can have different cross-section shapes, and can be provided inside of the each other by overpress fitting and interference fitting, or connect with each other by the connecting pin or the dead plate. A plurality of the second tube-shape bodies are side by side provided in the first tube-shape bodies. The invention also relates to a module system, including a plurality of tube-shape bodies (2, 3, 4) with a plurality of through holes or openings (9) on the sheath surface (10) and with different dimensions, making at least two different tube-shape bodies at least partly set inside of each other; connecting parts (8, 13, 14) connecting with the tube-shape body.

Description

technical field

[0001] The present invention relates to a position support implanted in a human body or an animal, in particular to a position support for a vertebra or an intervertebral disc, a manufacturing method and a modular system of the position support. Background technique

[0002] Position supports, especially for vertebrae or intervertebral discs, have been known for a long time. For example, DE 19504867 C1 discloses a position supporter in the shape of a cylindrical-tubular body with a plurality of rhomboid or rhomboid openings arranged in rows and columns. The end of the cylindrical tube is provided with protruding serrations and depressions corresponding to the rhombohedral shape, which are used to engage with adjacent vertebrae or adjacent tissues. The diamond-shaped openings encourage the in-growth of tissue into the implant so that it fits snugly into the body.

[0003] Furthermore, US 2005 / 0015154 discloses an implant having a scaffold-like structure in w...
