Vortex body replacement implant and a tool for handling of the vortex body replacement implant

摘要

Vortex body replacement implant with a lower base part comes to bear against a lower vertebral body and with an upper part of an installation for abutment against an upper vertebral body, whereby both parts of the plant according to the manner of a piston - cylinder - unit can be displaced telescopically relative to one another, with one of the parts of the plant formed, which is sealed hydraulic chamber, with a filling opening leading into the hydraulic chamber for a hydraulic medium, which in the entry into the hydraulic chamber pushes apart the two parts, and with a locking device, which can be activated by means of a tool, which the two components of the installation, in the case of activation fixed so as to be non-displaceable relative to one another, characterized in that the locking device (16, 27) in such a manner in the region of the filling opening (22) on the vortex body replacement implant (1) is arranged, that the locking device (16, 27) on the one hand and the filling opening (22) on the other hand are spatially combined.
