3D technologies, developed by Materialise, played a crucial role in the world’s first simultaneous double hand and face transplant that was successfully performed at NYU Langone Health in Manhattan, NY. Materialise’s innovative 3D planning and printing tools enable the speed and accuracy required for such a complex medical procedure. 3D printed personalized tools such as those used in the double hand and face transplant, are also increasingly common for use in routine surgery, providing surgeons with an additional level of confidence which results in improved patient outcome.
这位22岁的患者因车祸而遭受烧伤，使他的脸和双臂严重受伤。他对软组织遭受了重大破坏，这严重限制了他过正常生活的能力。在14个月的准备期间，实质性临床工程师与NYU Langone外科医生一起组成了一个有凝聚力的团队，在实验室环境中进行了练习，以制定和调整外科手术计划。一旦找到合适的捐助者，由Helen L. Kimmel重建整形手术教授Eduardo D. Rodriguez博士和HansjörgWyssnyu Langone的HansjörgWyss部门主席领导的团队，只有24小时开始procedure that would improve the patient’s function, appearance and quality of life.
In the months leading up to the surgery Materialise engineers coordinated the development of a surgical plan and created an on-screen 3D model based on CT-scans. This allowed the surgeons and clinical engineers to virtually plan the procedure and visualize different scenarios in three dimensions, creating an in-depth understanding of the anatomical bone structure and determining the optimal surgical flow. Pre-surgical planning also made it possible for surgeons to virtually select and position various medical implants to predict the optimal anatomical fit. Once the surgical plan was finalized, Materialise 3D printed the personalized surgical guides, anatomical models and tools for use during the transplant surgery.
During this momentous procedure, Rodriguez and his surgical team of sixteen used Materialise’s 3D printed cutting and drilling guides. This fully guided system for bone fragment repositioning and fixation was unique to the patient’s anatomy and helped position the medical tools with great precision, reducing the overall surgery time. Additionally, Materialise created 3D printed sterilizable identification tags for nerves and blood vessels, 3D printed models that were used during donor transport, and 3D printed splints, enabling optimal donor hand position during soft tissue reconstruction.
Rodriguez博士说：“像这样的复杂移植手术汇集了一大批专家团队，并提出了新的独特挑战。”“这需要仔细计划，并使时间，效率和准确性绝对至关重要。实际上，实际上计划了3D手术，并创建3D印刷的患者特定工具提供了在术前阶段提供的其他见解，并在关键时期手术中的速度和准确性提高了。”
“基于图像的计划和医疗3D打印已经通过为外科医生提供详细的见解和额外的信心，在进入操作室之前就完全彻底改变了个性化的患者护理，”北美总经理Bryan Crutchfield说。“因此，领先的医院正在采用3D规划和印刷服务作为其医疗实践的一部分，因为它们创造了一定程度的可预测性，如果不使用3D技术，就无法实现。”
Motialize开创了3D印刷的许多领先医疗应用，并使研究人员，工程师和临床医生能够开发创新的个性化治疗方法，以改善和挽救生命。软件和服务的物质平台构成了在临床和研究环境中认证的医疗3D打印的基础，提供虚拟计划软件工具，3D打印的解剖模型以及个性化的手术指南和植入物。
