  • Bone cement mixer with two paddles, the paddles arranged to limit longitudinal movement
    Patent number: 7967499
    Abstract: A mixing assembly for mixing bone cement includes a housing, a lid, a handle, and two mixing paddles, a first and a second mixing paddle. The lid is removably attachable to the housing. The handle has a portion that extends through the lid and that is rotatable in a first rotational direction. The first mixing paddle is operatively coupled to the portion of the handle. As a result, the first mixing paddle rotates with the portion of the handle in the first rotational direction. The second mixing paddle is operatively coupled to the first mixing paddle for rotating opposite the portion. As such, when the portion of the handle and the first mixing paddle rotate in the first rotational direction, the second mixing paddle rotates in a second rotational direction that is opposite the first rotational direction.
