Percutaneous vertebroplasty is an effective treatment for many focal vertebral lesions. Methyl methacrylate is too viscous to be handled without difficulty in the conventional way because injection time is short. The operator is left with little time and must fumble with multiple syringes. We describe a special screw-system syringe that decreases the effort needed to inject the cement. In addition, it can standardize the injection pressures and control the injected volume because the threaded plunger affords greater control of injection pressure and volume delivered than does the conventional method.
经皮椎体成形术是治疗多种椎体局灶性病变的有效方法。甲基丙烯酸甲酯黏性过大，采用传统方法操作时很难顺利进行，因为注射时间很短。术者几乎没有时间，必须笨拙地操作多个注射器。我们介绍一种特殊的螺旋系统注射器，它可减少注射骨水泥所需的力气。此外，它能使注射压力标准化并控制注射量，因为与传统方法相比，带螺纹的柱塞能更好地控制注射压力和输送的体积。
