Abstract

A method for enhanced surgical navigation, and a system performing the method and displaying graphical user interfaces associated with the method. A 3D spatial map of a surgical site is generated using a 3D endoscope including a camera source and an IR scan source. The method includes detecting a needle tip protruding from an anatomy and determining a needle protrusion distance corresponding to a distance between the needle tip and a surface of the anatomy using the 3D spatial map. A position of a surgical tool in the 3D spatial map is detected and a determination is made by the system indicative of whether the needle protrusion distance is sufficient for grasping by the surgical tool. A warning is generated when it is determined that the needle protrusion distance is not sufficient for grasping by the surgical tool.
