A tracker, a surgical navigation system with the tracker, and a method of operating the tracker are described. The tracker comprises a first switch configured to be operated between a first switch configuration and a second switch configuration. The tracker also comprises one or more sources of electromagnetic radiation configured to selectively emit electromagnetic radiation with a first radiation characteristic or a second radiation characteristic. The tracker further comprises electrical circuitry configured to selectively control the one or more sources of electromagnetic radiation to emit electromagnetic radiation having the first radiation characteristic in the first switch configuration and to emit electromagnetic radiation having the second radiation characteristic in the second switch configuration, wherein the second radiation characteristic is different from the first radiation characteristic.

The present disclosure relates to a housing assembly for accommodating printed circuit boards (PCBs). The housing assembly comprises a first housing portion configured to accommodate a first PCB, a second housing portion configured to accommodate a second PCB, and a separating portion for separating the first housing portion from the second housing portion. The separating portion comprises a first separating region in which the first housing portion and the second housing portion overlap and a second separating region that extends beyond the second housing portion and covers the first housing portion. The second separating region comprises one or more convection openings.

An optical tracking device, a surgical navigation system and a surgical navigation method are disclosed. The optical tracking device comprises a body having at least two optically distinguishable lines, wherein at least one of the lines is an edge of the body. The lines are configured to be detected by an optical detection system simultaneously. They have a fixed spatial relationship between each other. The method comprises providing the optical tracking device, acquiring data describing the fixed spatial relationship, detecting the lines and determining the spatial position and/or orientation of the optical tracking device based on the detected lines and the fixed spatial relationship.

A tracker, a surgical tool system, a surgical navigation system, and a method for operating a surgical navigation system are provided. The tracker is configured to be associated with a patient or a surgical tool that is to be tracked by the surgical navigation system. The tracker comprises an optical fibre having a longitudinal extension and configured to be optically coupled to a light source such that the optical fibre transmits light emitted by the light source. The optical fibre has a lateral surface along its longitudinal extension and is configured to emit light via at least a portion of the lateral surface.

A method, a controller, and a surgical hybrid navigation system for transferring a registration of three dimensional image data of a surgical object from a first to a second surgical navigation system are described. A first tracker that is detectable by a first detector of the first surgical navigation system is arranged in a fixed spatial relationship with the surgical object and a second tracker that is detectable by a second detector of the second surgical navigation system is arranged in a fixed spatial relationship with the surgical object. The method includes registering the three dimensional image data of the surgical object in a first coordinate system of the first surgical navigation system and determining a first position and orientation of the first tracker in the first coordinate system and a second position and orientation of the second tracker in a second coordinate system of the second surgical navigation system.
