The present invention relates to a device for producing a hardenable mass, preferably bone substitute and/or bone reinforcing material or bone cement or similar material. A mixing container may include a mixing space in which at least one powder and at least one liquid component are mixed to provide the hardenable mass. A piston may be provided in the mixing space of the mixing container. A screw device may be connectable to the mixing container such that the screw device may be configured to impart by screw movements a discharge movement to the piston to discharge the hardenable mass from the mixing space.

Device for producing a hardenable mass

The present invention relates to a device for producing a hardenable mass, preferably bone substitute and/or bone reinforcing material or bone cement or similar material. A mixing container () has a mixing space () in which at least one powder and at least one liquid component () are mixed to provide the hardenable mass (). A piston means () is provided in the mixing space () of the mixing container (). At least one means () which is rotatable relative to the mixing container () cooperates with the piston means () for, in a retaining position (P), retaining said piston means () relative to the mixing container () and, by rotation to a release position (P), releasing the piston means () such that said piston means can move in a direction (U) towards at least one opening () through which said mass () can pass out of the mixing space (). The rotatable means () is provided such that it in its release position (P) can follow the piston means () in the mixing space () in the direction (U) towards said opening ().

The present invention relates to a device for providing spongy bone with bone substitute and/or bone reinforcing material, wherein at least one perforating device () is provided for making at least one hole () in the spongy bone () and wherein at least one flushing or rinsing device () is provided for flushing or rinsing the hole () with a rinsing agent (). At least one vacuum source () is provided for generating a vacuum in the hole () in the spongy bone () for sucking and/or facilitating insertion or feeding of the bone substitute and/or bone reinforcing material () into said spongy bone (). The invention also relates to bone substitute and/or bone reinforcing material and methods in connection with the invention.
