Chirurgische navigationsreferenz mit spritzschutz

Abstract

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.
