Abstract

A surgical robot positions an end effector that guides movement of a surgical tool during a surgical procedure on a patient anatomical structure. A tracking system determines a pose of the anatomical structure and a pose of the end effector and/or the surgical tool. A navigation controller determines a target pose for the surgical tool based on a surgical plan and based on the pose of the anatomical structure, and generates steering information based on the target pose for the surgical tool, the pose of the anatomical structure, and the pose of the surgical tool and/or the end effector. The steering information indicates where the surgical tool and/or the end effector need to be moved. An AR headset controller receives the steering information from the navigation controller and displays a graphical representation of the steering information and/or the target pose for the surgical tool on a see-through display screen.
