Cannula assembly for providing enhanced navigation in a surgical site

A surgical system for performing a surgical procedure on a patient using a surgical tool, comprising:

• a cannula assembly including a cannula tube having a longitudinal axis, a proximal end portion and a distal end portion configured for insertion into a patient, the cannula tube having an internal lumen extending from the proximal end portion to the distal end portion, the cannula tube having a housing coupled to the cannula tube between the proximal and distal ends of the cannula tube so as to be positioned within the patient when the distal end of the cannula tube is inserted into the patient, the housing movable relative to the cannula tube between a closed position and an open position, the housing including a light source and an image sensor configured to provide a first image data stream of a patient's anatomy and the surgical tool when the housing is in the open position within the patient;
• a second imaging device configured for insertion into a patient and to provide a second image data stream of the patient's anatomy and the surgical tool;
• an image processor configured to receive the first and second image data streams and to process the first and second image data streams into a combined image data stream of the patient's anatomy and the surgical tool;
• a display device to display the combined image data stream to a user;
• a spatial processor configured to determine, based upon the combined image data stream of the patient's anatomy and the surgical tool, real-time positional data relative to the patient's anatomy and the surgical tool;
• and
• a navigation processor configured to generate and provide, based upon the real-time positional relationship data between the patient's anatomy and the surgical tool, navigation data to the user on the display device.
