Bone cement mixer

A bone cement mixing and dispensing system for mixing and delivering bone cement therefrom, the system comprising:

• a mixing container for holding a bone cement mixture, the mixing container extending along an axial length and having opposed first and second ends, the first end comprising a downstream opening for dispensing the bone cement from the mixing container;
• a mixing element movably disposed within the mixing container;
• a motor for driving the mixing element along the axial length of the mixing container;
• a plunger comprising a piston movably disposed within the mixing container;
• and
• a handle configured to manually drive the mixing element and the plunger along the axial length of the mixing container for dispensing the bone cement, after detachment of the mixing container from the stand
• wherein
• with a first coupling, the mixing element moves, by assistance of a motor, along the axial length of the mixing container to mix the bone cement without translation of the plunger, and
• with a second coupling, the mixing element and plunger are driven together along the axial length of the mixing container.
