Abstract
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.
Claims23
A method comprising:
- 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;
- 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;
- and
- while a mechanical hand tool is being used to prepare the anatomy for attachment of the prosthetic:
- determining a current depth of the mechanical hand tool;
- determining a relationship between the current depth of the mechanical hand tool and a target depth obtained from the virtual surgical plan;
- and
- outputting a representation of the relationship, wherein outputting the representation comprises either:
- outputting, via the visualization device, an audible representation of the relationship;
- or
- outputting a haptic representation of the relationship.
A mixed reality system comprising:
- a memory that stores at least a portion of a virtual surgical plan;
- and
- one or more processors configured to:
- display, 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;
- display, 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;
- and
- while a mechanical hand tool is being used to prepare the anatomy for attachment of the prosthetic:
- determine a current depth of the mechanical hand tool;
- determine a relationship between the current depth of the mechanical hand tool and a target depth obtained from the virtual surgical plan;
- and
- output a representation of the relationship, wherein, to output the representation, the one or more processors are configured to either:
- output, via the visualization device, an audible representation of the relationship;
- or
- output a haptic representation of the relationship.
A computer-readable storage medium storing instructions that, when executed, cause one or more processors of a mixed reality system to:
- display, 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;
- display, 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;
- while a mechanical hand tool is being used to prepare the anatomy for attachment of the prosthetic:
- determine a current depth of the mechanical hand tool;
- determine a relationship between the current depth of the mechanical hand tool and a target depth obtained from the virtual surgical plan;
- and
- output a representation of the relationship, wherein the instructions that cause the one or more processors to output the representation comprise instructions that cause the one or more processors to either:
- output, via the visualization device, an audible representation of the relationship;
- or
- output a haptic representation of the relationship.
