Implant, in particular a spinal implant

Abstract

A spinal implant, in the form of a multi-part connection device that couples a fastening element to a connection element, including a first part formed as a bracket, which has a receptacle for a part of the fastening element, and a second part in the form of a tulip, which has, in an axially upper region, a receptacle for the connection element and surrounds the bracket receptacle in an axially lower region. When the bracket is assembled in a predefined orientation in the tulip, the bracket can be axially moved in the tulip such that, when moved towards the upper region, in a receiving position the bracket can receive the part of the fastening element, and such that, when moved towards the lower region, in a holding position the bracket is no longer able to release the received part of the fastening element. An axial guide, for providing the axial movability, includes a projection region on the face of the bracket that is outside when viewed radially, which projection region engages in a cut-out region in the face of the tulip that is inside when viewed radially. The end regions, viewed azimuthally, of which projection region are spaced apart by at least 18°. An axial lock prevents the projection region from axially exiting the cut-out region towards the upper region, and a rotary lock prevents the projection region from rotationally entering the cut-out region and, when assembled, prevents the projection region from rotationally exiting the cut-out region.
