Advanced Materials Technologies:超逼真器官!3D打印更上一层楼

2017-12-11 佚名 中国生物技术网

现如今,3D打印已经风靡全球,医疗领域从此项技术中获益尤其多。到目前为止,研究人员使用该技术已打印出了人类软骨、皮肤,甚至是假肢,而我们对于3D打印潜在能力的理解才刚刚开始。现在,明尼苏达大学的研究人员已经开发出了令人难以置信超级逼真的人造器官模型。这项研究成果刚刚发表在《Advanced Materials Technologies》期刊上。

现如今,3D打印已经风靡全球,医疗领域从此项技术中获益尤其多。到目前为止,研究人员使用该技术已打印出了人类软骨、皮肤,甚至是假肢,而我们对于3D打印潜在能力的理解才刚刚开始。现在,明尼苏达大学的研究人员已经开发出了令人难以置信超级逼真的人造器官模型。这项研究成果刚刚发表在《Advanced Materials Technologies》期刊上。

明尼苏达大学科学与工程学院机械工程副教授Michael McAlpine是该研究论文的主要作者,他说:“我们正在开发用于术前实践的下一代器官模型。利用定制的3D打印机,我们打印出的这种器官模型无论是从外观还是感觉上就是人类器官的完美复制品。”

这些打印出来的3D器官结构不但模拟了真实器官的外表,还模拟了器官的机械特性,无论看上去还是感觉上都和真的器官一样。这些器官可以根据需求包含柔软的传感器。传感器提供实时的反馈信息,告诉医生多大力度时会损伤器官。

该技术可以帮助学生更好地感知真实器官,学习如何提升手术技巧。对于医生来说,这些器官可以帮助他们为复杂的手术做好准备。这相对于过去的人造器官模型是非常大的进步,过去的模型通常是由坚硬的、不真实的塑料制造而成的。

McAlpine补充说:“我们认为这些器官模型改变了“游戏规则”,可以帮助医生们更好地计划和实践手术。我们希望它可以通过减少手术过程中的医疗事故来拯救更多的生命。”

在未来,研究人员想要开发出更复杂的器官,并开始考虑引入缺陷和畸形的问题。比如,他们能够基于过去的筛查结果向器官模型中加入患者特有的炎症或肿瘤,使得医生们可以更好地观察到干预措施的效果并进行准备。

最后,该成果为打印出真正的有功能的器官铺平了道路。我们并没有理由不去这么做,只是我们现在还做不到,该发明使我们向着目标迈进了一大步。

McAlpine说:“如果能够复现这些组织和器官的功能,我们或许在未来某天就能够制造出用于移植的仿生器官。我将其称为‘人类X’计划。这听起来有点像科幻小说,但是如果这些人造器官无论是外观、感觉还是行为都和真正的器官一样,我们没有理由不使用3D打印技术来替换掉受损的器官。”
