独特植入式智能芯片问世 可以缓解慢性疼痛

有不少人经常性地头痛、手腕痛、腰背痛、关节痛,这就是慢性疼痛。目前,不少慢性疼痛还缺乏有效的根治方法,科学家只好从缓解慢性疼痛入手来进行研究。最近,澳大利亚的研究人员开发出一种独特的植入式智能芯片,据说可以缓解慢性疼痛。
  这种智能芯片的全称是“植入式神经刺激传感器”,可以植入到患者的脊椎旁边,对神经信号进行监测。这种芯片一旦监测到来自躯干各处的疼痛信号,就可以发射出高达10伏的电子脉冲来干扰传递疼痛感觉的神经信号,阻止疼痛信号的传递,让大脑不能感知疼痛,从而起到缓解疼痛的作用。
  由于智能芯片是靠手术植入到患者的脊椎旁,不可能没电了再用动手术的方法取出来换个新的。为了避免患者多次植入的痛苦,这种智能芯片采用无线充电的方式,其中内置的一小块充电电池可用电磁波进行无线充电。智能芯片不仅在治疗慢性躯干疼痛方面有着多种用途,而且还能用来阻止由神经损伤而引起的疼痛和偏头痛,甚至有可能来帮助控制癫痫病以及帕金森病的发作。
  虽然智能芯片不能清除引发慢性疼痛的病源,但是它并非治标不治本的权宜之计,因为不少病源本身对身体危害较小,它们的最大危害就是慢性疼痛。如果利用智能芯片缓解甚至消除了慢性疼痛,它就可以算是一种有效的治疗方法。研究人员表示,从2011年1月开始,这种智能芯片将进入临床试验,获得成功后再全面推广。
