Abstract: Systems, methods, and devices are disclosed for high accuracy molded navigation arrays. In example embodiments, a navigation array may be formed by molding, as a single component, an array having a plurality of marker regions that may include a reflective layer disposed thereon. In other embodiments, a navigation array may be formed by molding over a frame having a plurality of marker elements. In still other embodiments, a navigation array may be formed by molding over individual marker elements. In certain embodiments, a navigation array may be formed by molding a frame with a plurality of voids and subsequently molding marker elements into each void where the marker elements may include a reflective layer disposed thereon. In some embodiments, a navigation array may be formed by molding a plurality of marker elements on a frame and disposing a reflective layer on the marker elements.

Abstract: The disclosure relates to a robotic surgical system for treating an anatomical structure (B1), comprising: - a base (10) configured to be handheld by a user, - an end effector (13) holding a surgical tool (2), - an actuation unit (12) coupled to the end effector, configured to move the end effector relative to the base, - a tracking unit (3) configured to determine in real time a position of the surgical tool with respect to a coordinate system of the anatomical structure, - a control unit (6) coupled to the tracking unit and to the actuation unit, the control unit being configured to:  compute a path of the tool (2) to remove a planned volume of the anatomical structure, and  control the actuation unit to move the surgical tool according to the computed path to burr the planned volume, wherein the control unit is configured to determine an external surface (S) of the anatomical structure (B1) to be treated and to compute the tool path such that the surgical tool remains under said external surface (S) during treatment of the planned volume so as to avoid any contact of the surgical tool with another anatomical structure (B2).
