ABSTRACT:
The present invention relates to a device for storing and/or mixing and/or injecting cements, especially bone cements. The device includes a tube having a longitudinal axis, a front end with an outlet opening, a rear end; and an internal cylindrical cavity having a first end and a second end; a locking mechanism detachably connected to the front end of the tube so that the outlet opening can be sealed; and a lid detachably connected to the rear end of the tube; the lid having a borehole extending therethrough. The device also includes: a mixer having a mixing shaft sized and configured to extend through the borehole formed in the lid and a mixing tool at one end thereof, the mixer being axially and rotationally moveable inside of the cavity; a driving mechanism connected to the mixer shaft so that the mixer can be axially and rotationally moved with respect to the tube; and a first restraining mechanism for limiting the axial movement of the mixer with respect to the tube so that the a minimum distance A remains between the front face of the mixing tool and the front wall of the cavity; wherein the cylindrical cavity has a diameter D and the mixing tool has a maximum dimension X such that X is less than D.
