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. 11,857,235.

Summary of the Inventive Concept

A next-generation compression bone screw system that dynamically adjusts to individual patient needs, incorporating advanced sensors, micro-actuators, machine learning, and self-healing coatings to revolutionize bone compression and fusion.

Background and Problem Solved

The original differential compression bone screw patent (original_patent) has limitations in terms of fixed thread pitch and lack of real-time feedback. The new inventive concept addresses these limitations by introducing advanced technologies to create a more personalized, adaptive, and efficient bone compression system.

Detailed Description of the Inventive Concept

The Smart Compression Bone Screw System comprises a compression bone screw with a head portion and a distally extending shank. The shank includes a sensor for detecting bone density and a micro-actuator for adjusting thread pitch in response to the detected bone density. Additionally, the system features a machine learning module that analyzes patient-specific data and adapts thread pitch and compression force accordingly. The system also includes a self-healing coating that releases bioactive molecules to promote bone growth and regeneration. Furthermore, the system allows for real-time feedback to a surgeon's console, enabling more accurate and efficient bone compression.

Novelty and Inventive Step

The new claims introduce a paradigm shift in bone compression technology by incorporating advanced sensors, micro-actuators, machine learning, and self-healing coatings. These features enable real-time adaptation to individual patient needs, overcoming the limitations of fixed thread pitch and lack of real-time feedback in the original patent.

Alternative Embodiments and Variations

Alternative embodiments of the Smart Compression Bone Screw System could include interchangeable shank modules with varying thread pitches, universal head portions, or modular designs that allow for customization and flexibility. Variations could also include different sensor types, machine learning algorithms, or coating materials to further enhance the system's capabilities.

Potential Commercial Applications and Market

The Smart Compression Bone Screw System has significant commercial potential in the orthopedic and medical device industries, targeting applications in spinal fusion, joint replacement, and bone fracture treatment. The system's advanced features and adaptability make it an attractive solution for surgeons and patients seeking more efficient and effective bone compression and fusion.
