Enhanced Circular Fixator System with Advanced Rotational Control
Legal Citation
Summary of the Inventive Concept
An improved circular fixator system for orthopedic implants, featuring advanced rotational control mechanisms, enhanced stabilization, and modular design for total ankle replacement and joint stabilization procedures.
Background and Problem Solved
The original circular fixator system patent had limitations in terms of rotational control, stabilization, and component customization. The new inventive concept addresses these limitations by introducing adjustable stop mechanisms, built-in sensors, dynamic stabilization components, and modular designs to provide more efficient, accurate, and adaptable ankle joint stabilization and total ankle replacement procedures.
Detailed Description of the Inventive Concept
The enhanced circular fixator system comprises a foot holder with a rotation base plate having a retaining body defining a groove. The retaining body includes an adjustable stop mechanism to limit rotation of the foot holder relative to the retaining body. Additionally, the system features a built-in sensor to detect and adjust the rotational movement of the foot holder. The foot holder also includes a dynamic stabilization component that provides continuous adjustment of the rotational movement of the foot holder relative to the retaining body. Furthermore, the system incorporates a modular design, allowing for easy replacement or upgrading of components, thereby reducing the overall cost and complexity of the system.
Novelty and Inventive Step
The new inventive concept introduces several novel features, including the adjustable stop mechanism, built-in sensor, dynamic stabilization component, and modular design. These features provide a non-obvious improvement over the original patent, enabling more precise and adaptable ankle joint stabilization and total ankle replacement procedures.
Alternative Embodiments and Variations
Alternative embodiments of the enhanced circular fixator system could include variations in the adjustable stop mechanism, such as using different materials or geometries. Additionally, the system could be adapted for use in other orthopedic procedures, such as knee or hip joint stabilization. The modular design could also be applied to other medical devices, allowing for greater customization and flexibility.
Potential Commercial Applications and Market
The enhanced circular fixator system has significant commercial potential in the orthopedic implant market, particularly in the areas of total ankle replacement and joint stabilization. The system's advanced features and modular design could provide a competitive advantage in the market, appealing to surgeons and medical professionals seeking more efficient and effective procedures.
