The present invention refers to a device for the resection of bones (1) for preparing the attachment of an endoprosthesis to the joints which consists of at least two joint elements cooperating with each other, comprising at least one tool guide (3, 4, 5, 7, 14) and at least one support (6, 9, 10, 1
The present invention refers to a device for the resection of bones (1) for preparing the attachment of an endoprosthesis to the joints which consists of at least two joint elements cooperating with each other, comprising at least one tool guide (3, 4, 5, 7, 14) and at least one support (6, 9, 10, 15, 21) suitable for orienting the at least one tool guide (3, 4, 5, 7, 14), wherein, either in the immediate vicinity of the joint and/or across joints, the at least one support (15, 21) enables the at least one tool guide (3, 4, 5, 7, 14) to be oriented and positioned on a further joint element, or enables the at least one tool guide (3, 4, 5, 7, 14) to be oriented and positioned at the same joint element distally to the area to be treated and/or outside the surgical area. The at least one tool guide (3, 4, 5, 7, 14) and the at least one support are preferably immovably connected to each other so as to manufacture an individual single-use template. The invention also relates to a method for manufacturing such a device or template, an endoprosthesis suited for this purpose, a method for manufacturing such an endoprosthesis, and a surgical set consisting of said parts.
1. A device for preparing a bone for an implant comprising: a support portion comprising a plurality of elongate elements shaped as a reproduction according to corresponding elongate surface structures of the bone from a three-dimensional image of the bone, the plurality of elongate elements arrange
1. A device for preparing a bone for an implant comprising: a support portion comprising a plurality of elongate elements shaped as a reproduction according to corresponding elongate surface structures of the bone from a three-dimensional image of the bone, the plurality of elongate elements arranged to form at least one viewing opening through the device between adjacent elongate elements; anda tool guide portion attached to the support portion, the tool guide portion including a first tool guide oriented and positioned by the support portion to prepare an area of the bone for receiving an implant. 2. The device of claim 1, wherein the plurality of elongate elements includes a first plurality of spaced-apart sagittal elements and a second plurality of spaced-apart coronary elements forming a grid. 3. The device of claim 2, wherein the first tool guide includes a planar surface configured to guiding a resection of the bone along a plane for receiving an implant. 4. The device of claim 2, wherein the tool guide portion includes a plurality of tool guides. 5. The device of claim 2, wherein the tool guide portion includes a second tool guide configured for guiding fixation elements. 6. The device of claim 2, wherein the device is a tibial template and further comprising a support surface for a tibial bone, the support surface spaced apart from the support portion and attached to the support portion with an elongated bridge element. 7. The device of claim 2, wherein the device is a femoral template and includes a pair of lateral brackets supporting the coronary elements. 8. The device of claim 2, wherein the device is a tibial template and the support portion is shaped as a reproduction of a femoral knee implant. 9. The device of claim 2, wherein the sagittal elements are substantially parallel. 10. The device of claim 2, wherein the coronary elements are substantially parallel. 11. The device of claim 2, wherein the sagittal elements are substantially parallel and perpendicular to the coronary elements. 12. A device for preparing a bone for an implant, comprising: a support portion including a plurality of elongate elements shaped as a reproduction according to corresponding elongate surface structures of the bone from a three-dimensional image of the bone, the plurality of elongate elements arranged to form cavities that can engage anatomy of the bone and that can be flexed;a first tool guide portion including a first coronary tool guide and a second coronary tool guide, the first and second coronary tool guides parallel to each other and configured to cut a coronary area of the bone;a second tool guide portion including a first canthomeatal tool guide and a second canthomeatal tool, the first and second canthomeatal tool guides acutely angled with respect to each other; anda third tool guide portion that is perpendicular to the first tool guide. 13. The device of claim 12, wherein the support portion, the first tool guide portion, the second tool guide portion, and the third tool guide are integrally formed. 14. The device of claim 12, wherein the support portion has a grid-shaped structure. 15. The device of claim 12, wherein the plurality of elongate elements includes a first plurality of spaced-apart sagittal elements and a second plurality of spaced-apart coronary elements forming a grid. 16. The device of claim 12, wherein the first coronary guide defines a first tool path and the second coronary tool guide defines a second tool path, the first tool path parallel to the second tool path. 17. The device of claim 16, wherein the first canthomeatal tool guide defines a third tool path and the second canthomeatal tool guide includes a fourth tool path, the third and fourth tool path acutely angled with respect to each other. 18. The device of claim 17, wherein the third tool guide portion defines a fifth tool path that is perpendicular to the first and second tool paths. 19. The device of claim 1, wherein the tool guide further comprises a viewing opening to allow the at least some of the plurality of elongate elements to be viewed through the tool guide. 20. The device of claim 12, wherein each of the plurality of elongate elements is elastic.
