Techniques facilitating augmented reality-assisted surgery are provided. In one example, a method is provided that includes receiving, by a first device including a processor, image data associated with an external portion of a tool located within a body of a patient, wherein the image data includes first information indicative of a first fiducial marker on the external portion of the tool. The method also includes determining one or more relative positions of an internal portion of the tool within the body relative to one or more anatomical structures of the body based on the image data and a defined configuration of the tool. The method also includes generating one or more representations of the tool within the body relative to the one or more anatomical structures based on the one or more relative positions and the defined configuration of the tool.
