  • Patent number: 6261097
    Abstract: The proposal is for a holding element (100) which can be screwed into the internally threaded bore (14) of the implant (1) even during production of the latter and can thus be used to grip or hold the implant for the following production phases. Furthermore, the holding element (100) serves to fix an implant (1), which is screwed thereto, inside an ampoule (200) and for the application of a screwing-in tool for implantation. The particular feature of the ampoule (200) lies in the fact that it has a large-area, lateral cutout (231) in the casing and also a fixing part (210) for accommodating the holding element (100) in a clamped manner. The implant (1) can thus be pulled laterally out of the ampoule (200). The devices facilitate handling of the implant (1) during production and insertion into the bone.
