Abstract:
Devices and methods mix a bone cement and comprise at least one cartridge, wherein the cartridge comprises in its interior a cylindrical mixing chamber, a discharge piston movable in the cylindrical mixing chamber in the longitudinal direction and sealable against the walls of the mixing chamber, a mixing device for thoroughly mixing the content of the mixing chamber, which is arranged in the interior of the mixing chamber. The mixing device is operable externally via a mixing rod and the mixing rod is guided through a passage in the discharge piston such that it can be rotated and displaced in the longitudinal direction by the discharge piston. The cartridge comprises a discharge opening opposite the discharge piston, wherein, in the mixing chamber, a first component is contained between the discharge piston and the discharge opening, wherein a monomer fluid as a second component is introducable through the discharge opening into the mixing chamber. The device further comprises a locking element with which the mixing rod is affixable to the discharge piston such that the discharge piston is movable by means of the mixing rod in the mixing chamber in the longitudinal direction.
