Method and apparatus coupled to the bone connective tissue using a cortical bone anchor

摘要

The present invention relates to a bone anchoring device and the like for coupling to bone and connective tissue. Bone anchoring device has a (12) disks can be inserted into a portion of the bone to be joined to the connective tissue. The disk is movable between the illustrated bending of smaller cross section, between the expanded form is greater than the cross-section (not shown). It is used to insert into the cancellous bone region of the lower layer of the cortical bone through a small hole in the disk, then the bending form, becomes expanded form discs. Expanded form, because it is too large to return in a proximal direction through the holes in the cortical bone layer disc, the disc is permanently affixed to the inside of the cancellous bone. In the first embodiment, the disk is formed of spring steel in the expanded form, in the second embodiment, the disk is formed in the bent form, spring steel is not required.
