“慧思考”来主刀医术堪比医生高

2017-08-26 08:05:57   中国青年网

□本报记者王平本报通讯员崔冰心

提高假体安放的精确性、延长假体的使用寿命,一直是骨科医生实施关节置换手术追求的目标。如今,一台名叫“慧思考”的机器人不但能为患者“私人定制”手术方案,还能保证术中切割的精确度以及骨头和假体较高的吻合度,大大解放了外科医生的双手。

8月24日,记者从河南省人民医院获悉,该院引进的中原首台骨科手术机器人,近日成功为一名股骨头坏死的病人实施髋关节置换,顺利完成了它在我省开展的首例骨科手术。

10天前,45岁的祖先生因左下肢跛行和疼痛加重,来到省人民医院就医。经检查,他的左侧股骨头已严重坏死,需要手术治疗。该院骨科主任郑稼带领团队与省医特聘德国教授Boern-er一起,将患者的CT扫描输入了智能系统,通过3D模拟影像还原出祖先生的骨骼情况,为其定制一套严谨周全的手术方案,并同步将方案输入机器人的“大脑”。

术中,医生将两个骨圆针固定在祖先生的股骨头上,并用金属探针再将病人的实际位置和骨骼情况同步传输给机器人。根据点位数据,机器人再次将方案与实际相结合,通过系统计算,精准定位、成像,一系列操作平稳有序,手术进展十分顺利。

“手术中如何看到骨头深层内部病灶结构并准确操作,同时还要不损伤到其他组织,一直是骨科手术面临的最大难题。”郑稼告诉记者,这台“慧思考”机器人拥有目前世界上最新一代关节手术机器人系统,相较于以往人工截骨操作,它的“聪明”之处在于,能够根据植入物的形状调整磨钻速度和进度,精确地自动切割,还会选择不同阶段所用的磨钻尺寸。

除此之外,医生在手术中还可以随时调整机器人的操作,在任何时间暂停程序;当骨有移动时,机器人还会立刻停止磨钻,大大提高了关节置换手术的精准性。“毫不夸张,有了它的‘加盟’,关节置换的误差仅有0.1毫米,与植入物吻合度96%以上。同时,它还能降低术中骨折风险、精确恢复肢体长度、节约手术时间、减少出血及感染风险、提高关节手术治疗结果,也减少了影响医生术中稳定发挥的因素。”郑稼说。

据了解,今年4月1日,“慧思考”手术机器人正式落户河南省人民医院,这是继北京协和医院、解放军总医院之后,全国引入的第三台骨科手术机器人。②8
