Abstract

A system for utilizing and registering at least two surgical navigation systems during stereotactic surgery. The system comprises a first surgical navigation system defining a first patient space, a second surgical navigation system defining a second patient space, and a translation device to register the coordinates of the first patient space to the coordinates of the second patient space. The translation device comprises a rigid body, at least one component for a first navigation system placed in or on the rigid body, and at least one component for a second navigation system placed in or on the rigid body, in known relation to the at least one component for the first navigation system. The translation device is positioned in a working volume of each of the at least two navigation systems.

Claims
