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. 11,857,264.

Summary of the Inventive Concept

The present disclosure describes advanced surgical assistance systems that improve the accuracy, efficiency, and safety of physician-designed surgical procedures, particularly for spinal deformity correction.

Background and Problem Solved

The original patent addressed the need for surgical assistance in assessing spinal deformity. However, it had limitations in terms of implant selection, surgical planning, and real-time navigation. The new inventive concept solves these limitations by introducing advanced virtual anatomical modeling, implant configuration optimization, and real-time feedback generation.

Detailed Description of the Inventive Concept

The new system comprises a virtual anatomical model generator, an implant configuration optimizer, a virtual implantation simulator, and a real-time feedback generator. These components work together to provide a more accurate and efficient surgical planning process. The system receives virtual anatomical model data, analyzes it to identify potential implantation sites, and generates a ranked list of implant options. It also simulates the implantation procedure, providing real-time feedback to the surgeon. Additionally, the system can transmit criteria associated with a patient's spine to a cloud-based surgical planning platform, receiving a customized surgical plan based on the transmitted criteria and a virtual anatomical model of the patient's spine.

Novelty and Inventive Step

The new claims introduce novel features such as implant configuration optimization, real-time feedback generation, and cloud-based surgical planning. These advancements provide a non-obvious improvement over the original patent, enabling more accurate and efficient surgical procedures.

Alternative Embodiments and Variations

Alternative embodiments may include using machine learning algorithms to improve implant selection, integrating the system with robotic-assisted surgical systems, or developing specialized software for specific types of spinal deformities. Variations may also include using different types of sensors or tracking devices for real-time navigation.

Potential Commercial Applications and Market

The enhanced surgical assistance system has significant commercial potential in the orthopedic and spine surgery markets, with potential applications in hospitals, clinics, and surgical centers. The system can improve patient outcomes, reduce surgical complications, and increase the efficiency of surgical procedures, leading to cost savings and improved healthcare outcomes.
