ABSTRACT:
The trajectory of a surgical instrument or tool used for a stereotactic medical procedure is controlled by a passive apparatus having two pivots into which the tool may be inserted. The pivots, which serve as end effectors, are placed at points along a selected trajectory. The pivots are mounted to members attached to carriages. The carriages allow movement in a plane, whereas the members may move perpendicular to the plane. Indicia allow the pivots to be moved to a desired point and fasteners then secure the pivots in place, while allowing the pivots free rotation relative to two perpendicular axes.
