矫正脊柱不能调高低?3D打印植入物来帮忙

2017-06-27 石 岩 环球医学

自1986年美国科学家开发了第一台商业3D印刷机以来,人们便致力于完善3D打印技术并不断尝试在各个领域应用。特别是在医学领域,3D打印技术因为其个性化、快速的特点,可以帮助制作各种医疗辅助用具,譬如打印手术导板。

自1986年美国科学家开发了第一台商业3D印刷机以来,人们便致力于完善3D打印技术并不断尝试在各个领域应用。特别是在医学领域,3D打印技术因为其个性化、快速的特点,可以帮助制作各种医疗辅助用具,譬如打印手术导板。

近日,继美国食品和药物管理局(FDA)批准骶髂关节的钛3D打印植入物以治疗慢性腰痛之后,美国一家医疗器械公司宣布其3D打印脊柱支撑植入物获得了FDA的批准。有了这一认证,该公司的3D打印植入物现在可以用在人体内,以帮助纠正脊柱畸形。

据了解,上述3D打印植入物是开发公司利用他们之前的技术制成。颠覆传统制造技术的模式,该技术是一种基于粉末的激光熔融方法,可3D打印金属。使用该技术能引入有助于骨生长的材料特征,包括3-5μm的表面粗糙度和约70%的内部孔隙率。

这项打印植入物被设计用于脊柱靠下的后路腰椎部分。如果有需要,植入物的部件可以扩展或缩回,从而实现前后高度在扩展范围内无限调整。马里兰大学医学中心的脊柱外科医生Steven Ludwig博士说,植入物可以被锁定在任何想要的高度,以帮助恢复矢状平衡。这种独立调整的能力是现有装置不具有的。

除了3D打印植入物外,该公司还发布了一款软件,一个应用三维解决方案的平台,在整个对脊柱患者的临床护理中帮助连续推动质量结果。该软件通过向轴、冠和矢状面对每一个解剖椎体进行360度的评估,以达到平衡脊柱的目的,为手术成功提供基础。

去年,FDA已经批准了多项用于骨科矫正的3D打印物进入市场,如3D打印钛脊椎腰椎护架。未来,会有越来越多的材料或植入物被批准用于临床手术或者手术虚拟训练中。毋庸置疑的是3D打印技术正逐渐影响着骨科手术的方式,使更多人从中获益。
