Abstract:
A computer based system for positioning an article relative to a surgical target path using audio feedback, comprising:a memory storing a surgical target path expressed in terms of two or more spatial coordinates along a three dimensional surface representing a model of an anatomical object, the values of said spatial coordinates being indicative of a desired trajectory of said article along the surgical target path;one or more sensors tracking the actual trajectory of the article during surgical execution;a comparator providing on output differences between the desired trajectory and the actual trajectory of the article along said two or more spatial coordinates;a processor translating the provided differences along said two or more spatial coordinates into corresponding two or more coordinates of an audio space; andaudio means for playback of said two or more coordinates of the audio space to assist in positioning the article relative to the surgical target path.
