Augmented reality guidance for spinal surgery with stereoscopic displays

A system comprising:

• a stereoscopic optical see-through head mounted display;
• at least one computing system;
• and
• at least one camera, at least one 3D scanner, or a combination thereof,
• wherein the at least one computing system is configured to track at least a portion of a physical instrument, at least a portion of a physical spinal implant, at least a portion of a physical spine of a patient or a combination thereof using the at least one camera, the at least one 3D scanner, or the combination thereof,
• wherein the at least one computing system is configured to generate a three-dimensional (3D) surface representation of:
• at least a portion of a surgical guide, at least a portion of the tracked physical instrument, at least a portion of the tracked physical spinal implant, at least a portion of the tracked physical spine, at least a portion of an anatomical model, at least one image of the tracked physical spine, or a combination thereof,
• wherein the at least one computing system is configured to generate a two-dimensional (2D) display of:
• the at least portion of the surgical guide, the at least portion of the tracked physical instrument, the at least portion of the tracked physical spinal implant, the at least portion of the tracked physical spine, the at least portion of the anatomical model, the at least one image of the tracked physical spine, or a combination thereof,
• wherein the at least one computing system is configured to generate a stereoscopic view, displayed by the stereoscopic optical see-through head mounted display, the stereoscopic view comprising the 3D surface representation and the 2D display,
• wherein the at least one computing system is configured to superimpose the stereoscopic view of the 3D surface representation on a target portion of the physical spine,
• wherein the at least one computing system is configured to adjust in real time the stereoscopic view responsive to movement of the stereoscopic optical see-through head mounted display,
• wherein the at least one computing system is configured to adjust in real time the stereoscopic view responsive to movement of the physical spine from a first position to a second position, and
• wherein the first and second positions of the physical spine of the patient are different,
• wherein the system is configured to guide placement of the physical spinal implant.
