摘要:
An instrument for use in orthopaedic surgery for location of a reference point relative to a bone surface comprises a plate member (30) having at least two holes (36, 38) in it towards one end for receiving fasteners which can pass through the holes into the bone to fasten the plate member to the bone. A pivot rocker (40) is provided between the said holes, which protrudes from the face of the plate member which faces the bone surface when the plate member is positioned against a bone, and a reference point (44) is provided towards the opposite end of the plate member form the fastening holes which is spaced from the fastening holes in a direction parallel to the line which intersects the holes. The distance between the reference point on the plate member and the surface of the bone can be adjusted by moving the fastener in one of the fastening holes into the bone and moving the fastener in the other of the fastening holes out of the bone.

A connector for use in orthopaedic surgery for location of a surgical instrument relative to a reference point, comprises a plate member (30) having a reference point which can be fastened to the bone, and a connector rod (32) for connecting the surgical instrument (56) to the plate member. The connector rod is pivotally connected (44) to the plate member at about the reference point allowing relative pivotal motion between the connector rod and the plate member around at least one axis (46).

A plastic device containing an effective amount of an antibiotic to minimize bacterial and/or fungal infection at the site of implantation is disclosed.
摘要:
The invention relates to devices for removing an endoprosthesis or an implant which is implanted in the body and is made of a synthetic material. The inventive devices and methods are characterized especially by the fact that a minimal amount of tissue decomposes such that the endoprosthesis or the implant can be removed gently, the endoprosthesis, the implant, or a section thereof embodying a conductor. The endoprosthesis or the implant and at least one electrode that is connected in an electrically conducting manner to a surface area of the endoprosthesis of the implant, or at least one electrode which is in contact with a region of the material surrounding the endoprosthesis or the implant, are connected to an HF generator as an AC current source in order to separate the endoprosthesis or the implant from material surrounding the same in such a way that power is applied to the tissue and/or the biomaterial that surrounds the endoprosthesis or the implant. The endoprosthesis or the implant is coupled to an apparatus in order to be removed.
