  • Rigidly guided implant placement with control assist
    Publication number: 20070055291
    Abstract: A system for guiding an implant to an optimal placement within a patient includes a trajectory guide for guiding instruments along a selected trajectory and a trajectory fixation device for fixing the trajectory guide in a selected position. The trajectory guide defines a path configured to align with the selected trajectory. A movable support mounts the trajectory guide and selectively moves the trajectory guide to align the trajectory guide with the selected trajectory prior to fixing the trajectory guide in the selected position. The trajectory is aligned coarsely by hand, then the trajectory is aligned using a fine adjustment system. After fixing the trajectory guide, instruments can be inserted along the trajectory through the path defined by the trajectory guide.
