| 摘要 |
The invention relates to an elongate guide element (22) for guiding an implant (1) along a tunnel (17) in a bone (12, 14) and for securing the implant within the tunnel. One exemplary guide element comprises: first end and second ends (24, 26); a pair of support apertures (42) for receiving a support element (3) for the implant, the support apertures being spaced apart in a direction along a main longitudinal axis (28); a saddle (46) extending transverse to the longitudinal axis, one of the pair of support apertures being disposed between the saddle and the first end and the other between the saddle and the second end. The support element extends through one of the pair of support apertures, at least partly around the saddle and then through the other aperture. The guide element has a generally planar bone facing surface (48) and a second opposite surface (50). The guide element has a height, measured in a direction from the planar surface towards the second surface, the height increasing in a direction from the first and second ends towards an intermediate section of maximum height (H). At least part of the saddle is disposed within the intermediate section and defines a space (54) between the second surface and a maximum height extent of the saddle, for receiving part of the support element. |

1. An elongate guide element for guiding an implant along a tunnel in a bone and for securing the implant within the tunnel, the guide element comprising:
a first end, a second end opposite the first end, and a main longitudinal axis extending between said ends; a pair of support apertures for receiving a support element by which the implant can be coupled to the guide element, the support apertures being spaced apart in a direction along the main longitudinal axis; a saddle extending in a direction transverse to the main longitudinal axis, one of the pair of support apertures being disposed between the saddle and the first end and the other between the saddle and the second end, whereby, in use, the support element extends through one of the pair of support apertures, at least partly around the saddle and then through the other one of the pair of support apertures; and a generally planar bone facing surface and a second surface disposed opposite the bone facing surface; in which the guide element has a height, measured in a direction from the planar bone facing surface towards the second surface, the height increasing in a direction from the first end towards an intermediate section of maximum height disposed between the first and second ends, and in a direction from the second end towards the intermediate section; and in which at least part of the saddle is disposed within the intermediate section and defines a space between the second surface in the intermediate section and a maximum height extent of the saddle, for receiving part of the support element in order to couple the implant to the guide element. |
