Front Neurorobot:植入脑机接口操控机械臂,让瘫患者实现独立进食

2022-07-01 王聪 “Brain”公众号

究团队对一名因脊髓损伤导致上半身几乎瘫痪的男性的大脑植入了脑机接口,让他能够通过脑机接口操纵机械臂使用刀叉独立完成进食,整个过程用时不到90秒。

吃饭,对于普通人来说是个再简单不过的事情,但对于脊髓损伤导致双手运动能力丧失的人或瘫患者来说,这件简单的事却成为奢望,不得不依赖别人照顾。

2022年6月28日,美国约翰·霍普金斯大学的研究人员在 Frontiers in Neurobotics 期刊发表了题为:Shared Control of Bimanual Robotic Limbs With a Brain-Machine Interface for Self-Feeding 的研究论文。

研究团队对一名因脊髓损伤导致上半身几乎瘫痪的男性的大脑植入了脑机接口(Brain Computer Interface,BCI),让他能够通过脑机接口操纵机械臂使用刀叉独立完成进食,整个过程用时不到90秒。

这名49岁的男性已经长达30年双手无法运动,而现在,他在脑机接口的帮助下,能够操纵机械臂完成精细动作,这对于帮助那些患有感觉运动障碍的人恢复复杂运动行为具有重要意义。

该研究所植入的脑机接口由 Blackrock Neurotech 公司开发,Blackrock 公司成立于2008年,是一家全球领先的脑机接口(BCI)技术平台公司,致力于开发可改善人类生活的植入式脑机接口解决方案。

脑机接口(BCI)系统可提供大脑与计算机之间的直接通信链接,通过解码大脑神经信号并“翻译”这些信号以执行各种外部功能,在这项研究中,患者大脑的运动和体感皮层中植入了六个 NeuroPort 电极阵列(由 Blackrock 公司开发)。

这名上半身几乎瘫痪的患者的左右手做出微小的动作,通过脑机接口控制两只机械手臂使用刀叉切下甜点中的一小块,并用叉子送到嘴边进食。完成整个过程耗时不到90秒,实验成功率为85%(20次实验成功了17次)。

该论文的通讯作者 Francesco V. Tenore 博士表示,尽管这项结果是初步的,但依然很高兴能够为运动能力受限的患者提供帮助,真正操控日益智能的辅助机器。

该论文的第一作者 David Handelman 博士表示,这项研究展现的机器人技术的最大进步之一是将机器人的自主性和人类有限的输入信息相结合,由机器人完成大部分工作,同时用户还能够根据自己的情况或喜好自定义机器人的行为。

研究团队还表示,接下来将整合之前研究成果,帮助截肢患者通过大脑来控制假肢的运动并通过假肢执行任务。
