Bone cement and a system for mixing and delivery thereof |
摘要 |
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.
