This technical disclosure describes improvements that would be readily apparent to a Person Having Ordinary Skill In The Art (PHOSITA) when considered in combination with the foundational architecture disclosed in U.S. Patent No. 11,857,206.

Summary of the Inventive Concept

A next-generation osteotomy system that leverages machine learning, 3D printing, and real-time surgical navigation to provide personalized surgical plans, tools, and guidance for optimal patient outcomes.

Background and Problem Solved

The original patent disclosed patient-specific surgical tools for high tibial osteotomies. However, these tools were limited to validating wedge openings and did not provide a comprehensive solution for personalized osteotomy planning and execution. The new inventive concept addresses this limitation by introducing a system that integrates data-driven planning, customized tool fabrication, and real-time navigation to ensure accurate and effective osteotomy procedures.

Detailed Description of the Inventive Concept

The inventive concept comprises a database of patient-specific anatomical data, a machine learning module trained to predict optimal surgical parameters, and a 3D printing module for fabricating customized surgical tools based on the predicted parameters. The system also includes a real-time surgical navigation module that tracks the patient's bone movement during the procedure and generates a 3D model of the patient's bone in real-time, providing visual feedback to the surgeon to ensure accurate alignment of surgical tools. Additionally, the system can be used to simulate osteotomy procedures, identify optimal scenarios, and provide personalized osteotomy planning.

Novelty and Inventive Step

The new claims introduce a paradigm shift in osteotomy procedures by integrating machine learning, 3D printing, and real-time navigation. The inventive concept's novelty lies in its ability to provide personalized surgical plans, tools, and guidance, which is a significant departure from the original patent's focus on validating wedge openings.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include the use of different machine learning algorithms, 3D printing materials, or navigation systems. Variations could also include the application of the system to other types of osteotomy procedures or orthopedic surgeries.

Potential Commercial Applications and Market

The inventive concept has significant commercial potential in the orthopedic surgery market, particularly in the area of personalized medicine. The system could be marketed to hospitals, clinics, and surgeons, offering a competitive advantage in terms of accuracy, efficiency, and patient outcomes.
