Cutting tool for cleaning out the femur medullary space and artificial hip to be inserted into this space

Abstract

Milling tool for emptying the femoral medullary space, while creating a space for the shaft of a hip prosthesis, which comprises a flexible core (10) and a plurality of conical, rotationally symmetrical milling segments (12), mounted in superimposed manner on the core (10) and provided with a central through-bore, the milling segments (12) being so connected to the core (10) and/or the milling segments (12) adjacent thereto, that a rotational force applied to the core (10) and/or the upper segment (12) is transferred to the individual milling segments (12), as well as a hip prosthesis with a conically directed shaft and a ball (16) mounted on the proximal end of the shaft and which comprises a flexible core (10), a plurality of conical, rotationally symmetrical segments (12), mounted in superimposed manner on the core (10) and provided with a central through-bore and a device (14) for tensioning the core (10) to bring about a stiffening of the shaft formed from the individual segments (12).
