Abstract
Systems and methods for performing computer-aided surgical navigation using augmented reality are disclosed. An augmented reality marker assembly including a tracking marker configured for use with an augmented reality system is configured to be attached to a tracking device at a fixed orientation. The tracking marker includes a contrasting three-dimensional surface. The system can sense and determine a three-dimensional orientation of the augmented reality marker and the tracking device in their respective reference frames.
Claims20
A surgical system comprising:
- a tracking device comprising a first tracking marker configured for use with a surgical navigation tracking system, the tracking device configured to be mounted to a patient;
- an augmented reality marker assembly comprising a second tracking marker configured for use with an augmented reality system, the augmented reality marker assembly configured to be attached to the tracking device at a fixed orientation, wherein the second tracking marker comprises a contrasting three-dimensional surface;
- a sensor assembly configured to identify locations of each of the first tracking marker and the second tracking marker;
- and
- a control system communicably connected to the sensor assembly, the control system configured to:
- determine a first three-dimensional orientation of the patient in a first reference frame by locating the first tracking marker via the sensor assembly, and
- determine a second three-dimensional orientation of the augmented reality marker assembly in a second reference frame by locating the second tracking marker via the sensor assembly.
A tracking device attachment for correlating a tracking system coordinate frame with an augmented reality system coordinate frame, the tracking device attachment comprising:
- a tracking marker comprising a contrasting three-dimensional surface configured to be identified by an augmented reality system;
- and
- a plurality of fastening mechanisms configured to attach the tracking device attachment to a tracking device at a fixed orientation, wherein the tracking device comprises a marker configured to be identified by a surgical navigation system and configured to be mounted to a patient.
A surgical system comprising:
- a sensor assembly configured to:
- identify a first location of a first tracking marker associated with a tracking device, the tracking device configured to be mounted to a patient, wherein the first tracking marker is configured for use with a surgical navigation system, and
- identify a second location of a second tracking marker associated with an augmented reality marker assembly, the augmented reality marker assembly configured to be attached to the tracking device at a fixed orientation, wherein the second tracking marker comprises a contrasting three-dimensional surface configured for use with an augmented reality system;
- and
- a control system communicably connected to the sensor assembly, the control system configured to:
- determine a first three-dimensional orientation, in a first reference frame of the patient by locating the first tracking marker via the sensor assembly, and
- determine a second three-dimensional orientation, in a second reference frame, of the augmented reality marker assembly by locating the second tracking marker via the sensor assembly.
