Abstract
A surgical guidance system includes a magnetic field generator carried by a support frame, a guidance system controller, at least one magnetic field sensor located at a surgical instrument, and a feedback display device. The guidance system indicates the position of the surgical instrument relative to a trajectory as the surgical instrument approaches a surgical target within a body. The magnetic field generator establishes a magnetic field having geometric characteristics that indicate the trajectory from an initial point to the target. The sensors detect the distinguishable orientation of the magnetic field along the trajectory, and the feedback display device indicates whether the surgical instrument is aligned or misaligned with the trajectory. The magnetic field generator is adjustable upon the support frame such that the approach angle and position of the trajectory may be selected.
