Surgical navigation trackers with guards are described that can aid in protecting tracking elements from accumulating liquids thereon, which can negatively impact surgical navigation performance. The surgical navigation trackers described herein can be utilized with a variety of systems and procedures. For example, in one embodiment a system is described that includes a surgical device having an end effector configured for manipulating tissue and a surgical navigation tracker configured to be coupled to any of a surgical instrument and an anatomical structure. The surgical navigation tracker can include a tracking element and a guard configured to be positioned between the tracking element and the cutting tool, as well as a tracking unit configured to determine a position of the surgical navigation tracker.

The invention relates to a surgical system for cutting an anatomical structure (F, T) of a patient according to at least one target plane defined in a coordinate system of the anatomical structure, comprising: (i) a robotic device () comprising: &#x2014;an end effector (), &#x2014;an actuation unit () having at least three motorized degrees of freedom, configured for adjusting a position and orientation of the end effector () relative to each target plane, &#x2014;a passive planar mechanism () connecting the terminal part () of the actuation unit () to the end effector (); (ii) a tracker () rigidly attached to the end effector (), (iii) a tracking unit () configured to determine in real time the pose of the end effector () with respect to the coordinate system of the anatomical structure, a control unit () configured to determine the pose of the end effector with respect to the target plane and to control the actuation unit so as to bring the cutting plane into alignment with the target plane.
