Implant (1) for receiving the connecting bridge (17, 17′, 17″) of a medical device, comprising a longitudinal axis (9), a distal end (3) and a proximal end (4), whereby a receiving recess (10) for the connecting bridge (17, 17′, 17″) extends therefrom inside the implant (1), wherein the implant (1) can be connected on its outer surface area to the inner surface area of a receiving bore hole in a bone by force or adaptation, and whereby the connecting bridge (17, 17′, 17″), which is adapted to the receiving recess (10), can be anchored through clamping, shrinkage, adhesion or cementing. The anchored medical device rests on a contact surface (18) of the top (16) protruding radially outward in its cross-section beyond the cross-section of the receiving recess (10) on the proximal end (4) of the implant (1) across the entire surface against an allocated contact surface (5) of the implant (1) on its proximal end (4). In order to accomplish this the medical device can be easily assembled while simultaneously ensuring a high torsional safety as well as even force transmission between the implant and the medical device it is suggested that extending from the proximal end (4) of the implant (1) the receiving recess (10) contain a cylindrical section (10Z), which is followed by a section (10V) that is tapered in its cross-section, and that extending from the top (16) of the medical device the connecting bridge (17, 17′, 17″) also contain a cylindrical section (17Z), which is followed by a section (17V) that is tapered in its cross-section.
Implant (1) for receiving a connecting bridge (17, 17′, 17″) of a medical device, comprising a longitudinal axis (9), a distal end (3) and a proximal end (4), whereby a receiving recess (10) for the connecting bridge (17, 17′, 17″) extends therefrom into implant (1), wherein the implant (1) can be connected by its outer surface area to the inner surface area of a receiving bore hole in the bone of a human or animal body by force or adaptation, whereby the connecting bridge (17, 17′, 17″), which is adapted to the receiving recess (10), can be anchored through clamping, shrinkage, adhesion or cementing, wherein in the anchored medical device rests in contact with the contact surface (18) of the top portion (16) protruding radially outward in its cross-section beyond the cross-section of the receiving recess (10) on the proximal end (4) of the implant (1) across the entire surface against an allocated contact surface (5) of the implant (1) on its proximal end (4) and the outer contour of the cross-section of the receiving recess (10) at least in one section is not circular, characterized by the fact that extending from the proximal end (4) of the implant (1) the receiving recess (10) contains a cylindrical section (10Z), which is followed by a section (10V) that is tapered in its cross-section, and that extending from the head portion (16) of the medical device the connecting bridge (17, 17′, 17″) also contains a cylindrical section (17Z), which is followed by a section (17V) that is tapered in its cross-section.
Medical device, characterized by the fact that it rests on the contact surface (18) of a head portion (16) protruding radially outward in its cross-section beyond the cross-section of the receiving recess (10) on the proximal end (4) of the implant (1) across the entire surface against an allocated contact surface (5) of the implant (1) on its proximal end (4), that the outer contour of the cross-section of the connecting bridge (17, 17′, 17″) at least in one section is not circular, and that extending from a head portion (16) the connecting bridge (17, 17′, 17″) has a cylindrical section (17Z), which is followed by a section (17V) that is tapered in its cross-section.
