New patent application published for: Alert System Behavior Based On Localization Awareness

A hand-held surgical system includes an instrument configured to be held in a hand of a user and including a drive motor. The instrument is coupled to a tracking device. The hand-held surgical system also includes a tracking unit, an alert module, and a control system in communication with the tracking unit, the alert module, and the instrument. The control system is configured to track a pose of the instrument in a known coordinate system with the tracking unit, determine a boundary associated with a region of interest in a surgical procedure in the known coordinate system, control the alert module based on the boundary and the tracked pose of the instrument, determine that an occlusion event has occurred for the tracking device, and control the drive motor based on the occlusion event, the boundary, and the tracked pose of the instrument.
