Abstract
A device to be used in combination with a surgical navigation system for defining the position of a straight line determined by an operating surgeon within a three-dimensional coordinate system in an operating theater. The devices includes a body () with a surface () and at least three markers () which emit waves () and the position of which can be determined within a three-dimensional coordinate system by a position detector belonging to the surgical navigation system. A laser () mounted on the body () emits a laser beam (), directed away from the body (), which has a geometrical central beam () and a wavelength in the visible range. The laser beam () is emitted in a geometrically defined position relative to the markers () so that the position of the central beam () relative to the three-dimensional coordinate system can be calculated from the previously measured positions of the markers () by a computer, which is also part of the surgical navigation system.
