Abstract

A surgical instrument navigation system is disclosed that allows a surgeon to invert the three-dimensional perspective of the instrument to match their perspective of the actual instrument. A data processor is operable to generate a three-dimensional representation of a surgical instrument as it would visually appear from either of at least two different perspectives and to overlay the representation of the surgical instrument onto an image data of the patient. The image data and the representations can be displayed on a display.

Claims13

Dependent claims

A method for displaying a representation of a surgical instrument using a surgical instrument navigation system, comprising:

providing image data representative of a patient;
rendering a first three-dimensional representation of the surgical instrument as it would visually appear from a first perspective;
displaying the rendering of the surgical instrument superimposed onto the image data of the patient;
rendering a second three-dimensional representation of the surgical instrument as it would visually appear from a second perspective;
and
displaying the rendering of the surgical instrument as it would visually appear from at least one of said first perspective or said second perspective that is selectable by an operator of the surgical instrument navigation system.
