A method for easily calibrating both the position of the tip of a surgical
tool and the orientation of that tool includes attaching a tracking
device capable of communication with the surgical navigation system to
the surgical tool using an adapter, where the adapter has a known
relation between the tracking device and the axis of the surgical tool.
The method then performs a calibration process to calculate the position
of the tip of the surgical tool and the position of the tracking device
and orientation data for the surgical tool from the known relation
between the tracking device and the axis of the surgical tool and from
the tool tip position. Lastly, the method stores the position of the tool
tip for the surgical tool and the orientation data within memory of the
surgical navigation system so the position and the orientation of the
surgical tool can be tracked by the surgical navigation system.The
adapter has a body with an interior surface that defines an opening
through which a surgical tool can be inserted, the opening having an
axis. The adapter also has a docking structure for a tracking device such
that there is a known relation between the tracking device and the axis
of the opening and the axis of a tool that is inserted in the opening.
