摘　　要：目的研究机械臂辅助下脑深部电刺激(DBS)术的精确性。方法回顾性分析应用机械臂(华科精准)辅助下脑深部电刺激术治疗的10例运动障碍患者的临床资料。患者术后进行CT复查确认电极位置坐标、入路角度,与术前设计靶点坐标、入路角度比较;并计算每根(共20根)电极设计靶点与实际靶点的距离。结果电极实际与设计入路角度的差异无统计学意义(均P>0.05);实际与设计位置坐标中的右侧X、Y和左侧Y值的差异有统计学意义(P<0.05~0.01),其他坐标值间的差异无统计学意义。两者的三维直线距离为(1.81±0.81)mm,去除深度因素的平面距离为(1.41±0.82)mm。结论机械臂辅助下脑深部电刺激术是安全、精确的,完全可以满足治疗的需要精度。Objective To define the accuracy of robotic assistance in deep brain stimulation surgery and to compare the results in the literature.Methods The data of 10 patients with dyskinesia treated by deep brain electrical stimulation assisted by mechanical arm(Huake precision)were reviewed retrospectively.Postoperative CT review confirmed the comparison between electrode position coordinates,approach angle and preoperative designed target coordinates and approach angle data.The accuracy was analyzed between the intended location of the target and actual location of leads.Results There is no statistically significance between the actual and intended entry angle.Right side X,Y and left side Y coordinates of actual distal contacts were significantly different between the actual and intended entry angle(P<0.05-0.01).Others had no statistically significance.The euclidian 3 D distances between the intended and actual location of the contact were(1.81±0.81)mm.Mean radial error was(1.41±0.82)mm.Conclusion Robot-assisted technology for stereotactic surgery is safe and accurate.
