Bone-anchoring or bone-connecting device that induces a strain stimulus

摘要

The invention relates to an implant in the form of a bone-connecting device with an implant carrier, having at least two structure carriers for stimulating bone growth, the structure carriers can move relative to one another so that, due to a loading of the implant, a relative movement of the structure carriers occurs, the structure carriers furthermore contain structure elements that are arranged so that they define a plurality of partially open intermediate spaces, wherein a volume defined by these intermediate spaces and an immediate environment is deformed by the implant load, and a strain in the intermediate spaces and its immediate environment resulting from the deformation lies in the physiological range for bone growth.

主权项

1. An implant in the form of a bone-connecting device comprising:
an implant carrier body having a first end and an opposite second end, each end for applying a force and joining to an existing bone structure; a structure carrier connected to the first end of the carrier body and having a length extending in a direction toward the second end of the carrier body, wherein an intermediate space is defined between the structure carrier and the carrier body, wherein the structure carrier is formed with a structured surface comprising structure elements disposed within the intermediate space defined between the structure carrier and the carrier body, and wherein the surface structure of the structure carrier in the intermediate space is configured so that the intermediate space can be colonized by tissue, and wherein the surface structure of the structure carrier moves relative to the carrier body as a result of a mechanical loading of the first and second ends of the carrier body.
