Virtual guidance for orthopedic surgical procedures
An example method includes displaying, via a visualization device and overlaid on a portion of an anatomy of a patient viewable via the visualization device, a virtual model of the portion of the anatomy obtained from a virtual surgical plan for an orthopedic joint repair surgical procedure to attach a prosthetic to the anatomy; and displaying, via the visualization device and overlaid on the portion of the anatomy, a virtual guide that guides at least one of preparation of the anatomy for attachment of the prosthetic or attachment of the prosthetic to the anatomy.
1. A method comprising:
obtaining, by one or more processors, a virtual model of a portion of an anatomy of a patient;
displaying, via a visualization device, one or more virtual guides that guide at least one of preparation of the anatomy for attachment of a prosthetic to the anatomy or attachment of the prosthetic to the anatomy; and
displaying, via the visualization device and overlaid on the portion of the anatomy, at least a portion of the virtual model such that the portion of the virtual model at least partially obscures the portion of the anatomy with an exception of a virtual hole surrounding a location on the portion of the anatomy indicated by the one or more virtual guides, wherein the location on the portion of the anatomy within the virtual hole is entirely unobscured by the portion of the virtual model due to the virtual hole in the portion of the virtual model.
2. The method of claim 1 , wherein the displaying the portion of the virtual model comprises:
displaying the portion of the virtual model as fading between a perimeter of the portion of the virtual model and the location on the portion of the anatomy indicated by the one or more virtual guides.
3. The method of claim 1 , wherein the displaying the one or more virtual guides comprises projecting the one or more virtual guides via one or more see-through lenses through which a user is able to view at least the portion of the anatomy of the patient.
4. The method of claim 3 , wherein the displaying the portion of the virtual model comprises displaying the portion of the virtual model via the see-through lenses.
5. The method of claim 1 , wherein the displaying the one or more virtual guides comprises displaying one or more of:
a virtual axis; or
a virtual cutting surface.
6. The method of claim 1 , wherein the anatomy comprises a glenoid of a scapula of the patient.
7. The method of claim 6 , wherein the displaying the one or more virtual guides comprises:
displaying a virtual reaming axis having parameters obtained from a virtual surgical plan, the virtual reaming axis configured to guide reaming of the glenoid.
8. The method of claim 7 , wherein the virtual reaming axis is configured to guide attachment of a guide pin to the scapula.
9. The method of claim 1 , wherein the displaying the one or more virtual guides comprises displaying the one or more virtual guides in a green color.
10. A mixed reality system comprising:
a memory;
a visualization device; and
one or more processors configured to:
obtain, from the memory, a virtual model of a portion of an anatomy of a patient;
display, via the visualization device, one or more virtual guides that guide at least one of preparation of the anatomy for attachment of a prosthetic to the anatomy or
attachment of the prosthetic to the anatomy; and
display, via the visualization device and overlaid on the portion of the anatomy, at least a portion of the virtual model such that the portion of the virtual model at least partially obscures the portion of the anatomy with an exception of a virtual hole surrounding a location on the portion of the anatomy indicated by the one or more virtual guides, wherein the location on the portion of the anatomy within the virtual hole is entirely unobscured by the portion of the virtual model due to the virtual hole in the portion of the virtual model.
11. The mixed reality system of claim 10 , wherein the one or more processors are configured to display the portion of the virtual model as fading between a perimeter of the portion of the virtual model and the location on the portion of the anatomy indicated by the one or more virtual guides.
12. The mixed reality system of claim 10 , wherein:
the visualization device comprises one or more see-through lenses through which a user is able to view the anatomy of the patient, and
to display the one or more virtual guides, the one or more processors are configured to project the one or more virtual guides via the one or more see-through lenses.
13. The mixed reality system of claim 12 , wherein the one or more processors are configured to display the portion of the virtual model via the see-through lenses.
14. The mixed reality system of claim 10 , wherein, to display the one or more virtual guides, the one or more processors are configured to display one or more of:
a virtual axis; or
a virtual cutting surface.
15. The mixed reality system of claim 10 , wherein the anatomy comprises a glenoid of a scapula of the patient.
16. The mixed reality system of claim 15 , wherein, to display the one or more virtual guides, the one or more processors are configured to:
display a virtual reaming axis having parameters obtained from a virtual surgical plan, the virtual reaming axis configured to guide reaming of the glenoid.
17. The mixed reality system of claim 16 , wherein the virtual reaming axis is configured to guide attachment of a guide pin to the scapula.
18. One or more non-transitory computer-readable storage media storing instructions that, when executed, cause one or more processors of a mixed reality system to:
obtain a virtual model of a portion of an anatomy of a patient;
display, via a visualization device, one or more virtual guides that guide at least one of preparation of the anatomy for attachment of a prosthetic to the anatomy or attachment of the prosthetic to the anatomy; and
display, via the visualization device and overlaid on the portion of the anatomy, at least a portion of the virtual model such that the portion of the virtual model at least partially obscures the portion of the anatomy with an exception of a virtual hole surrounding a location on the portion of the anatomy indicated by the one or more virtual guides, wherein the location on the portion of the anatomy within the virtual hole is entirely unobscured by the portion of the virtual model due to the virtual hole in the portion of the virtual model.
