Mixed Reality Overlay for Shoulder Implant Positioning

The patent performs all necessary imaging, 3D modeling, and surgical planning actions in advance before the surgery. The preoperative CT scans are processed to create accurate 3D models of the glenoid anatomy and bone defects, and virtual surgical simulations are conducted beforehand. This preliminary preparation allows the actual surgery to proceed more quickly since the surgical path and implant positioning are already optimized in the virtual model.

The patent creates a virtual 3D copy of the patient's glenoid anatomy and bone defects from preoperative CT scans. This digital replica allows surgeons to rehearse the surgery, test different implant positions, and optimize the surgical approach without time-consuming intraoperative adjustments. The virtual model serves as a template that guides the actual surgical procedure, eliminating the need for complex real-time navigation systems.

The patent performs comprehensive preoperative evaluation including CT scans, 3D modeling, and virtual surgical planning before the surgery. This preliminary analysis allows the surgeon to assess the glenoid bone defects and design the optimal surgical approach in advance, enabling confident single-stage revision surgery with improved reliability while avoiding the time loss and morbidity associated with 2-stage procedures.

The patent uses virtual surgical simulations and 3D visualization to provide feedback on different surgical approaches and implant positioning options before the actual surgery. This feedback mechanism allows the surgeon to optimize the surgical plan based on the virtual results, ensuring that the single-stage procedure achieves reliable outcomes that would traditionally require multiple stages.

The patent creates a virtual 3D copy of the scapular anatomy and glenoid defects from preoperative CT scans, eliminating the need for physical 3D printing. This digital replica provides the same manufacturing precision for implant positioning while significantly reducing device complexity and costs by avoiding the need for 3D printing equipment, physical models, and associated laboratory attempts.

The patent replaces the mechanical 3D printing process with a digital virtual modeling system. Instead of physically printing 3D models that require handling, storage, and alignment during surgery, the system uses computer-generated 3D visualizations that can be displayed and manipulated digitally, simplifying the entire surgical preparation process while maintaining positioning accuracy.

The patent uses preoperative CT scan data to create accurate 3D virtual copies of the patient's anatomy and glenoid defects. These digital models serve as the basis for surgical planning and guidance, providing implant positioning accuracy without requiring complex intraoperative navigation hardware, sensors, or real-time computational systems.

The patent performs all imaging, modeling, and surgical planning actions in advance before the surgery. The virtual 3D models are created and optimized beforehand, allowing the actual surgery to proceed with simpler equipment and fewer intraoperative complexities, while still achieving high manufacturing precision through the pre-planned virtual surgical guide.
