Device to be coupled to at least one holder, in particular surgical implant to be coupled to a bone

摘要

The implant has a fixing unit (3) with a head (3A) and a shaft, and an assembly unit (4) with an opening hole. A ring (6) has a passage to allow the passage of the shaft and to create a stopping unit for the head. The ring is expandable along its axial direction between an initial configuration in which it is adjusted relative to the hole and an expanded configuration in which it is blocked relative to the hole.
