陶瓷电机帮助手术机器人实现精确移动

人类的手、眼限制是神经外科医生多年来一直面临的难题。即便是最精湛、最有经验的医生也只能达到一定的精确度,他们进行外科手术操作时通常受到视觉的限制。虽然技术进步使外科医生能探视到人体内部,但在MRI环境下进行显微手术仍存在一定挑战。电机及其金属元件的磁性导致手术机器人难以在MRI环境下工作,因此无法进行显微操作。

加拿大卡尔加里大学(www.ucalgary.ca)的国际专家小组和高级信息产品与系统供应商MacDonald, Dettwiler, and Associates有限公司(MDA;加拿大不列颠哥伦比亚省,Richmond;www.mdacorporation.com)最近计划制造一种能在MRI系统的强磁场环境中安全地进行显微手术的机器,以解决上述难题。他们开发出的neuroArm据称是全世界第一款兼容MRI环境的图像导向手术机器人,能够进行显微手术和立体定向。

为克服磁性障碍,该小组还向JohnsonMedtech网络的成员,Nanomotion公司(纽约州Ronkonkoma;www.nanomotion.com)寻求服务。Nanomotion公司的专家联合设计并开发出一种非磁性传动器,能进行精确移动以保证neuroArm完成显微手术操作。

neuroArm共采用16枚Nanomotion公司的HR2-1-N-3压电超声非磁性电机,以及AB5驱动模块。这些电机包括6个旋转接头。通过MRI对人体进行实时检测获得体内视图,neuroArm中的Nanomotion传动器令外科医生能对工具进行微操作,完成以前很难或无法安全完成的手术。

卡尔加里大学神经外科教授Garnette Sutherland说:“我们的设计团队在开发neuroArm的过程中克服了许多难题。其中之一就是neuroArm需要在MRI的强磁场环境中进行操作且精度要求极高。”

陶瓷电机除具有非磁性优势外,Nanomotion的精确移动控制产品可提高外科医生进行手术的精度。人手的操作精度为1/8英寸,而neuroArm的精度可达人类发丝的宽度。

JohnsonElectric公司高级副总裁JimDick说:“我们与neuroArm国际设计团队密切合作,克服了在MRI系统的无菌手术室中,医生使用手术操作器械时面临的众多难题。neuroArm改善了手术操作,从而提高全世界患者进行手术时的安全性和成功率。
