Patent ID: 8617180

Claim:
System for stereotaxy of several different patients, comprising at least three anchors intended to be attached to a patient being treated and equipped with markers, wherein each of said markers is directly attached to a top portion of each of said anchors, which thereby results in an anchors and markers combination, wherein each anchors and markers combination is individually positionable on the patient; an insertion guide device with an insertion guide removably attached to the anchors and markers combination, an external calibration device with at least three calibration markers corresponding to said markers attached to the patient, wherein the at least three calibration markers are directly attached to at least a portion of the external calibration device, and a planning and imaging software; wherein the insertion guide is removably attached directly to said markers of the calibration device; and wherein the calibration device is adaptable to the patient being treated for orienting the insertion guide to reach the target point in the patient by orienting said guide on the calibration device reproducing a calibration target corresponding to the patient target point, wherein once the position of said target point in the patient with respect to the markers attached to the patient has been determined by said planning and imaging software, the insertion guide of the insertion guide device mounted on said calibration markers is calibrated and oriented using the determination of said software before the insertion guide device is mounted on said markers attached to the patient such that the insertion guide is thereby oriented towards the target point in the patient.
