    Publication number: 20240024007
    Abstract: A bone cement mixing and dispensing system and method for mixing and delivering bone cement therefrom. The system has 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 downstream from the mixing container; a mixing element movably disposed within the mixing container; and a plunger comprising a piston movably disposed within the mixing container. In this system. with a first coupling, the mixing element moves by assistance of a motor along the axial length of the mixing container without translation of the plunger to mix the bone cement. In this system. with a second coupling, the mixing element and plunger are driven together along the axial length of the mixing container.
