Cranial insertion placement verification

Abstract:

A system and method for verifying the accurate insertion positioning of a robotically guided surgical tool or probe, at its cranial target region, such as for Deep Brain Stimulation. A head mounted robot aligns a probe or tool guiding sleeve, together with an aiming rod attached at a predefined position and angle to the guiding sleeve. The aiming rod incorporates apertures through which an X-ray system can view the patient's skull. The aiming rod is attached to the tool guiding sleeve at an angle and position calculated such that the line of sight through the apertures falls exactly on the target region when the tool or probe is inserted to its predetermined depth. If the tip of the tool or probe is seen located at the center of the apertures in the X-ray image, verification is obtained that the insertion procedure has been performed accurately.
