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

This invention relates to novel patient-specific surgical tools and systems designed to improve the accuracy, efficiency, and safety of orthopedic surgical procedures, such as high tibial osteotomies, by introducing modular, customizable, and sterilizable components.

Background and Problem Solved

The original patent disclosed patient-specific opening validating tools for knee osteotomy procedures. However, these tools had limitations, including being non-modular, non-sterilizable, and lacking customization options. The new inventive concept addresses these limitations by introducing advanced patient-specific surgical tools and systems that provide improved flexibility, precision, and hygiene.

Detailed Description of the Inventive Concept

The inventive concept comprises a system of patient-specific surgical tools, including modular surgical guides with interchangeable modules, customizable surgical guides designed using 3D models of a patient's anatomy, and removable and sterilizable operative sides. These components work together to provide surgeons with precise, efficient, and safe tools for performing orthopedic procedures. The system also includes a method for validating the accuracy of patient-specific surgical tools through virtual modeling and simulation.

Novelty and Inventive Step

The new inventive concept introduces novel features, such as modularity, customizability, and sterilizability, which are not present in the original patent. These features provide significant improvements in terms of flexibility, precision, and hygiene, and are not obvious from the original patent.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include using different materials or manufacturing methods for the surgical guides, or integrating sensors or other technologies to provide real-time feedback during procedures. Variations could also include adapting the system for use in other types of surgical procedures or developing specialized modules for specific procedures.

Potential Commercial Applications and Market

The advanced patient-specific surgical tools and systems have significant commercial potential in the orthopedic surgical market, particularly in the area of knee osteotomy procedures. The market for these tools is expected to grow as the demand for precise, efficient, and safe surgical procedures increases.
