Abstract: This invention is a system for use during a medical or surgical procedure on a body. The system generates an image representing the position of one or more body elements (10, 20, 30) using scans generated by a scanner prior or during the procedure. The image data set has reference points (10A)-(30C) for each of the body elements, the reference points of a body element having a fixed spatial relation to the body element. The system includes an apparatus (108) for identifying the relative position of each of the reference points of each of the body elements to be displayed. The system also includes a processor (104) for modifying the image data set according to the identified relative position of each of the reference points during the procedure. Also disclosed are devices for use with a surgical navigation system having a sensor array (110, 112) in communication with the device to identify its position.

Abstract: A surgical distractor for distracting tissue of a patient to access structure underlying the tissue of the patient. The distractor includes a tube having a distal end adapted for insertion in tissue, a proximal end opposite the distal end, an exterior surface adapted for contacting the tissue, and an interior surface opposite the exterior surface defining a hollow interior extending between the distal end and the proximal end for accessing structure underlying the tissue when the distal end is inserted in the tissue. The distractor is adjustable from a reduced configuration, in which the tube has a reduced width sized for inserting the distal end in the tissue, and an expanded configuration, in which the tube has an expanded width greater than the reduced width sized to provide the hollow interior with a size sufficient for accessing the structure underlying the tissue.

Abstract: This is a system for determining a position of a probe (302) relative to an object such as a head of a body of a patient. The head includes a surface such as a forehead having a contour. Cross-sectional images of the head are scanned and stored as a function of the forehead contour. If the forehead contour does not appear in the scan images, then the position of the forehead contour relative to the scan images is determined with an optical scanner (380) and ring (590). During surgery, the optical scanner (380) also determines the position of the tip of the forehead relative to the ring (590). An array (300) for receiving radiation emitted from the probe and from the ring generates signals indicating the position of the tip (301) of the probe (302) relative to the ring (590). A stereo-tactic imaging system (324) generates and displays an image of the head corresponding to the measured position of the tip (301) of the probe (302).

Abstract: A system for determining a position of a probe (302) relative to an object such as a head (390) of a body of a patient. The head includes a surface such as a forehead (394) having a contour. The head is placed in a cradle (392) equipped with an arc (393). The cross-sectional images of the head are determined relative to the arc. A hand-held unit (380) optically scans the forehead and the arc. During scanning to generate the cross-sectional images, the optical scanner (380) is used to determine the position of the forehead (394) relative to the cradle (392). During surgery, the optical scanner (380) also determines the position of the forehead (394) relative to a base ring (306). An array (300) for receiving radiation emitted from the probe (302) and from the base ring (306) generates signals indicating the position of the tip of the probe (302) relative to the base ring (306). A stereotactic imaging system selects and displays the image of the head closest to the measured position of the tip of the probe (302).

Abstract: Un système de détermination d'une position d'une sonde (302) par rapport à un objet tel que la tête (390) du corps d'un patient est décrit. La tête comprend une surface telle que le front (394) présentant un contour. La tête est placée dans un berceau (392) équipé d'un arc (393). Les images en coupe transversale de la tête sont déterminées par rapport à l'arc. Une unité portable (380) explore optiquement le front et l'arc. Pendant l'exploration en vue de produire les images en coupe transversale, le scanner optique (380) est utilisé pour déterminer la position du front (394) par rapport au berceau (392). Pendant l'opération chirurgicale, le scanner optique (380) détermine également la position du front (394) par rapport à l'anneau de base (306). Un réseau (300) recevant la radiation émise par la sonde (302) et par l'anneau de base (306) génère des signaux indiquant la position de la pointe de la sonde (302) par rapport à l'anneau de base (306). Un système d'imagerie stéréotactique sélectionne et affiche l'image de la tête la plus proche de la position mesurée de la pointe de la sonde (302).
