美国发明修复烧伤“喷射”设备,可快速植皮

据国外媒体报道,近日一名美国医生发明了一种治疗烧伤的新医疗设备—具有“科幻风格”的喷枪,这种设备可以将皮肤的健康细胞“喷射”到烧伤者的受伤皮肤上,以使烧伤部位重新长出皮肤。虽然对皮肤用“枪”已经不再是“科学幻想”,但是过去的“标准”植皮方法往往需要数周的时间,不过现在“科幻风格”喷枪完成植皮工作仅需要不到两小时的时间,并且还可以使烧伤部位在在数天之内愈合。

 

近日匹兹堡大学麦克哥尔恩(McGowan)再生医学研究院的格尔拉彻(J?rg Gerlach)医生发明了一种治疗烧伤的新方法,这种方法通过从患者身上提取出健康的皮肤干细胞,并用喷枪将这些干细胞“喷射”到烧伤者的皮肤上来治疗烧伤的皮肤。据悉,虽然科学家能够使皮肤“再生”的时间已经长达几十年,但是过去的方法要经过漫长的过程并且再生出来的皮肤非常脆弱。即使给烧伤者提供了正确的护理和着装,但在长期的治疗过程中烧伤者都会暴露在各种危险的感染中,有的烧伤者甚至会死去。而格尔拉彻的干细胞喷枪治疗法能在90分钟内治疗烧伤皮肤,并将烧伤皮肤的愈合时间缩减至数天。

“科幻风格”喷枪治疗烧伤的第三个阶段,烧伤部位逐渐愈合

据悉,干细胞因其较强的自我更新能力而著名,它们扮演着身体的一个“修复系统”的角色。“科幻风格”喷枪通过从烧伤者身上的健康皮肤部位分离出干细胞,并将这些干细胞“加入”到一种将被用来喷射到烧伤皮肤上的溶液中。据悉,来自宾夕法尼亚州的马修•尤瑞(Matthew Uram)警官是首批接受“科幻风格”喷枪治疗的患者之一,他因参加一个朋友的聚会而受到了严重的二度烧伤,其脸部、耳朵、肩膀、手臂等多个部位烧伤严重。不过他在接受了干细胞喷射治疗4天之后,他的皮肤已经完全愈合,现在已经看不出明显的烧伤痕迹。
