Preliminary experience with the ISG wand for frameless stereotaxy is presented. The wand is a multijointed mechanical arm with a range of 25 inch radius sphere. The arm has a analog/digital hybrid transducers to locate the spatial position of the probe tip. The real time displays of triplanar 2D images with an optional 2D/3D image helps in surgical planning and interactive surgery. Seventeen patients underwent neurosurgical procedures with the help of wand. The wand was used to place minimal craniotomies, localise the brain-tumour interface and excise the lesions. The wand had an accuracy of 1.8 mm (SEM +/- 0.36 mm) in localising the lesions. Thus, the use of frameless stereotaxy has made easier and more precise surgical planning in several applications.
介绍了ISG棒用于无框架立体定向的初步经验。该棒是一个多关节机械臂，作用范围为半径25英寸的球体。该臂具有模拟/数字混合传感器，用于定位探头尖端的空间位置。三平面二维图像的实时显示以及可选的二维/三维图像有助于手术规划和交互式手术。17名患者在该棒的帮助下接受了神经外科手术。该棒用于进行最小开颅手术、定位脑肿瘤界面并切除病变。该棒在定位病变方面的精度为1.8毫米（标准误±0.36毫米）。因此，在多种应用中，无框架立体定向的使用使手术规划更加轻松和精确。
