Claims30
A method of preparing a physical joint in a patient comprising:
- generating, by at least one computer, a virtual surgical guide, wherein the virtual surgical guide is a virtual plane, wherein the virtual plane is a three-dimensional digital representation indicating at least one of a predetermined resection level, a predetermined resection angle, a predetermined varus or valgus angle, a predetermined flexion, or a predetermined slope, for superimposing one or more physical surgical tools or physical surgical instruments;
- and
- displaying, at the at least one of the predetermined resection level, predetermined resection angle, predetermined varus or valgus angle, predetermined flexion, or predetermined slope, using a see through optical head mounted display, the virtual plane onto a surface of the physical joint visible directly through the see through optical head mounted display, wherein the virtual plane is configured to allow superimposition of the one or more physical surgical tools or physical surgical instruments with the virtual plane,
- wherein the display of the virtual plane at the at least one of the predetermined resection level, predetermined resection angle, predetermined varus or valgus angle, predetermined flexion, or predetermined slope is configured to be maintained by the at least one computer in relationship to one or more anatomic structures, wherein the one or more anatomic structures are registered in a coordinate system,
- wherein the physical joint of the patient, and the one or more physical surgical tools or physical surgical instruments are visible directly through the see through optical head mounted display,
- wherein the one or more physical surgical tools or physical surgical instruments are configured to perform one or more bone cuts or a bone removal of the joint,
- wherein the virtual plane is registered in the coordinate system, and
- wherein the see through optical head mounted display is registered in the coordinate system.
