湘雅三医院:3D打印技术用于脊柱截骨手术

2016-03-31 成舸 吴勇 中国科学报

湖南湘雅三医院脊柱外科主任医师詹瑞森团队采用3D打印截骨导板,成功为一名患者实施脊柱截骨手术,让患者重见天日。据了解,这是全国范围内首次将3D打印技术应用于脊柱截骨手术。 邓先生患有强直性脊柱炎,随着年龄增长,脊柱僵硬、后凸日趋严重,弯曲达到110度,导致严重驼背,1.7米的个头被压到只有1.3米,体重也降至不到80斤。经诊断,医疗团队决定在邓先生的脊柱上截去两节骨头,帮患者基本恢复直立状

湖南湘雅三医院脊柱外科主任医师詹瑞森团队采用3D打印截骨导板,成功为一名患者实施脊柱截骨手术,让患者重见天日。据了解,这是全国范围内首次将3D打印技术应用于脊柱截骨手术。

邓先生患有强直性脊柱炎,随着年龄增长,脊柱僵硬、后凸日趋严重,弯曲达到110度,导致严重驼背,1.7米的个头被压到只有1.3米,体重也降至不到80斤。经诊断,医疗团队决定在邓先生的脊柱上截去两节骨头,帮患者基本恢复直立状态。

由湖南华曙高科制备的该3D打印导板是一个尼龙材质的辅助器具,将该器具卡在要截去的脊椎骨上,骨刀从施刀口进入,严格控制了施刀的角度和深度,确保手术精准、微创,其精细程度堪称“私人定制”。

“脊柱是人的中枢系统,神经分布密集,对施刀的精准度要求极高,稍有不慎便可能造成患者失血过多甚至瘫痪。”詹瑞森介绍,以前做该手术,施刀定位全凭医生经验和肉眼判断,风险很高。此外,以传统方式做该手术,手术时间约10小时,患者出血量约为6000毫升,术后需进入重症监护室1周,而邓先生的手术时间约5小时,出血量仅2000毫升,术后直接进入普通病房,1周内可下地走动,费用也省了几万元。
