Device for bone fixation with at least one through hole |
摘要 |
A device for bone fixation defining at least one through hole extending therethrough, the through hole including first and second through apertures separated from one another by a first resilient element deformable radially outward from the first aperture to expand the first aperture and contract the second aperture, the second aperture being sized and shaped to receive therein a bone fixation element, the second through aperture being smaller in size than the first through aperture, a periphery of the first through aperture comprising at least two substantially circular arcs B1 and B2 with respective radii R1 and R2 and respective centers Z1 and Z2 located at a distance X≧0 extending transversely to the resilient element whereby the ratio R1:R2 is in the range between 0.5 and 2.0. |

1. A device for bone fixation defining at least one through hole extending therethrough, the through hole including first and second through apertures separated from one another by a first resilient element deformable radially outward from the first aperture to expand the first aperture and contract the second aperture, the second aperture being sized and shaped to receive therein a bone fixation element, the second through aperture being smaller in size than the first through aperture, a periphery of the first through aperture comprising at least two substantially circular arcs B1 and B2 with respective radii R1 and R2 and respective centres Z1 and Z2 located at a distance X>0 extending transversely to the resilient element whereby the ratio R1:R2 is in the range between 0.5 and 2.0, wherein the through hole further comprises a third through aperture which does not overlap the first and second apertures, the third through aperture being separated from the first through aperture by a second resilient element deformable radially outward from the first aperture to expand the first aperture and contract the third aperture, the third aperture being sized and shaped to receive therein a bone fixation element. |
