• a surgical visualization system is configured to leverage “digital surgery” to obtain additional information about a patient’s anatomy and/or a surgical procedure.
• the surgical visualization system is further configured to convey data to one or more medical practitioners in a helpful manner.
• Various aspects of the present disclosure provide improved visualization of the patient’s anatomy and/or the surgical procedure, and/or use visualization to provide improved control of a surgical tool (also referred to herein as a “surgical device” or a “surgical instrument”).
• Digital surgery can embrace robotic systems, advanced imaging, advanced instrumentation, artificial intelligence, machine learning, data analytics for performance tracking and benchmarking, connectivity both inside and outside of the operating room (OR), and more.

• digital surgery can occur without robotics and/or with limited and/or optional robotic assistance.
• a surgical system that incorporates a surgical visualization system may enable smart dissection in order to identify and avoid critical structures.
• Critical structures include anatomical structures such as a ureter, an artery such as a superior mesenteric artery, a vein such as a portal vein, a nerve such as a phrenic nerve, and/or a tumor, among other anatomical structures.
• a critical structure can be a foreign structure in the anatomical field, such as a surgical device, a surgical fastener, a clip, a tack, a bougie, a band, a plate, and other foreign structures.
• Critical structures can be determined on a patient-by-patient and/or a procedure-by-procedure basis.

• a surgical visualization system may provide improved tissue characterization and/or lymph node diagnostics and mapping.
• tissue characterization technologies may characterize tissue type and health without the need for physical haptics, especially when dissecting and/or placing stapling devices within the tissue.
