    • A bone cement formulation stored as a solid component pack having 0.3 to 20 solid component pack weight percent of an elastomer and a polymer bead core having a polyacrylate terminated surface. The second component pack is a liquid component pack including an acrylate monomer. An alternate solid component pack includes 3 to 25 solid component pack weight percent of a polyacrylate and a rubber toughened polymethyl methacrylate. A cement mixing and delivering system according to the present invention includes a tube having an exit nozzle and an aperture. An end plate is adapted to seal against the interior of the tube aperture and the end plate has a plurality of needles protruding therefrom into the tube. A rotatable and slidable divider is received within the tube intermediate between the end plate and the exit nozzle. The divider includes at least two plates. Each of the plates has a plurality of apertures that upon alignment the needles of the first plate are urged through the apertures of the at least two divider plates.
    • 一种作为固体组分包装储存的骨水泥配方,其具有0.3至20个固体组分包装重量百分比的弹性体和具有聚丙烯酸酯封端表面的聚合物珠芯。 第二组分包是包含丙烯酸酯单体的液体组分。 一种替代的固体组分包装包括3至25个固体组分包装重量百分比的聚丙烯酸酯和橡胶增韧的聚甲基丙烯酸甲酯。 根据本发明的水泥混合和输送系统包括具有出口喷嘴和孔的管。 端板适于密封管孔的内部,并且端板具有从其中突出到管中的多个针。 可旋转和可滑动的分隔件容纳在管板中间在端板和出口喷嘴之间。 分隔器包括至少两个板。 每个板具有多个孔,在对准时,第一板的针被推动通过至少两个分隔板的孔。
