BONE ANCHOR ELEMENT FOR INSERTION INTO A BONE AND/OR FIXATION OF TISSUE TO THE BONE, INSERTION TOOL, BONE ANCHOR SYSTEM AND METHOD FOR PREPARING A BONE ANCHOR SYSTEM

摘要

The invention relates to a bone anchor element for introducing into a bone and / or fixing tissue to the bone, the bone anchor element having a proximal end, a proximal section, a distal section and a distal end in a longitudinal direction, and the proximal section having a profiled end on the outside Notch to prevent the bone anchor element introduced into the bone from being pulled off and has a continuous cavity in the longitudinal direction with a proximal opening and a distal opening on the inside, and the distal section is flattened in the shape of a plate with a plate plane, the bone anchor element having at least one transverse opening for receiving one Having suture material, and the distal section in the longitudinal direction to the distal end has a first transverse opening through the plane of the plate, the first transverse opening connected to the continuous cavity of the proximal section via the distal opening en, and then has a second transverse opening through the plane of the plate, the first transverse opening and the second transverse opening being separated by a web of the plate-shaped distal section, and the second transverse opening at the distal end having a gap opening in the longitudinal direction and essentially transversely to the plane of the plate, so that the suture material can be guided flexibly through the continuous cavity, the first transverse opening, the second transverse opening and / or the gap opening, and the web on its proximal side to the first transverse opening has an inclined stop surface such that if an eyelet is pushed through from the proximal Opening through the continuous cavity of the bone anchor element, through the distal opening and through the first transverse opening in the longitudinal direction, the eyelet being guided outwards through the first transverse opening when it hits the inclined stop surface. The invention also relates to a feeder, a bone anchor system and a method for assembling a bone anchor system.
