Embodiment Construction

[0039] figure 1 A bone implant 1 according to the invention is shown for attachment at the surface 2 of a human skull 3 . The bone implant 1 has a plate-shaped base body 4 . The underside 5 of the base body 4 is the flat side or surface of the base body 4 which, in the attached state on the skull 3, faces the skull 3 and rests against the skull 3 . on said surface 2 of said skull 3 . The upper side 6 of the basic body 4 is the flat side or surface of the basic body 4 which faces away from the skull 3 in the attached state. The upper side 6 is thus situated opposite the lower side 5 .

[0040] The curvature of the underside 5 corresponds, for example, to the undeformed or defect-free outer contour 7 of the skull 3 . For example, the curvature of the upper side 6 corresponds substantially to the undeformed or defect-free outer contour 7 of the skull 3 . The bone implant 1 thus corresponds to a flat-surfaced bone layer or plate in the skull 3 before bone material is removed ...

Abstract

The invention relates to a bone implant (1) for attaching to on a surface (2) of a bone (3), including a base body (4) whose lower side (5) and / or upper side (6) correspond(s) substantially to a deformation-free bone outer contour (7), wherein the outer dimensions of the base body (4) are chosen such that the base body (4) covers a specifically introduced deformation region (8) for obtaining autologous bone material completely, wherein in the base body (4) at least one slot (9) is provided which is dimensioned such that it guides a bone marking and / or bone processing tool (10) inserted in theslot (9) in use.

Description

technical field [0001] The present invention relates to a bone implant for repairing or restoring the condition of a bone (osteotomy) and for attachment to a bone, in particular the surface of the skull. Background technique [0002] Bone implants for filling and / or closing defects and / or for repositioning in the skull are known from the prior art. For example, document DE 20 2014 103 858 U1 discloses an implant for reduction and fixation of centrolateral facial fractures (zentrolateralen Mittelgesichtsfraktur), wherein the implant comprises a plurality of preformed segments, preferably three or more pre-shaped segments, wherein the shape of the first segment is designed such that at least its lower side adjacent to the bone is completely or partially complementary to the anatomy of at least a partial region of the outer side of the maxilla wherein the shape of the second segment is such that at least its lower side adjacent to the bone is completely or partially complement...
