    • The invention relates to an adaptor for tracking an instrument location during image guided surgery. The adaptor has a drive shaft, a proximal handle and a distal instrument tip. The drive shaft has a linear proximal portion, a curved mid-portion and a linear distal portion that is co-linear with the linear proximal portion. Three tracking elements (such as reflective balls) are placed on the sinusoidal portion. When the handle is rotated, the two linear portions remain fixed on the longitudinal axis, but the tracking elements on the sinusoidal portion travel in orbits about the longitudinal axis, thereby allowing a computer to track the location of the instrument tip.
    • 本发明涉及用于在图像引导手术期间跟踪仪器位置的适配器。 适配器具有驱动轴,近侧手柄和远端仪器尖端。 驱动轴具有线性近端部分,弯曲中部部分和与线性近端部分共线的直线远端部分。 三个跟踪元件(如反射球)被放置在正弦部分上。 当手柄旋转时,两个线性部分保持固定在纵向轴线上,但是正弦部分上的跟踪元件围绕纵向轴线行进,从而允许计算机跟踪仪器尖端的位置。
