Abstract: Described herein are methods and systems for selecting surgical approaches. One example method involves (1) receiving data indicating (a) one or more surgical target regions and (b) one or more surgical portals; (2) determining a plurality of surgical pathways; (3) determining a plurality of surgical approaches; (4) for each surgical approach in the plurality of surgical approaches, determining at least one approach characteristic, for each determined surgical pathway in the respective surgical approach, determining at least one pathway characteristic, and determining a surgical-approach ranking based on the determined at least one approach characteristic and the determined at least one pathway characteristic; (5) selecting a subset of the plurality of surgical approaches based on the determined surgical approach rankings; and (6) causing an output device to provide a representation of the selected subset of the plurality of surgical approaches.

Abstract: Described herein are methods and systems for defining surgical boundaries. One example method involves receiving data indicating a representation of a patient; receiving data indicating (i) a surgical target region within the representation of the patient; and (ii) a surgical entry portal within the representation of the patient; providing a graphical display of (i) the representation of the patient, and (ii) a surgical pathway from the surgical entry portal to the surgical target region; defining one or more surgical boundaries within the representation; receiving data indicating a position of a surgical instrument with respect to the representation; based on the received data indicating the position of the surgical instrument, determining that the surgical instrument is within a threshold distance from the one or more surgical boundaries; and providing feedback indicating that the surgical instrument is within the predetermined threshold distance from the one or more surgical boundaries.
