Modular Acetabular Cup System with Customizable Liners and Advanced Features
Legal Citation
Summary of the Inventive Concept
A modular acetabular cup system with interchangeable liners of varied geometries, a locking mechanism, and advanced features such as sensors and self-lubricating surfaces to improve the efficiency, safety, and customization of hip replacement surgeries.
Background and Problem Solved
The original acetabular cup system patent has limitations in terms of accommodating different anatomical features and providing real-time monitoring of liner wear and tear. The new inventive concept addresses these limitations by introducing a modular design with customizable liners, sensors, and advanced materials to enhance the overall performance and longevity of the hip replacement system.
Detailed Description of the Inventive Concept
The modular acetabular cup system comprises a cup assembly with interchangeable liners of varied geometries, designed to accommodate different anatomical features. The liners are secured in place using a locking mechanism, ensuring a precise fit and reducing the risk of misalignment. The system also incorporates a sensor to monitor the wear and tear of the liner, providing real-time data to the surgeon. Additionally, the system features a self-lubricating surface and a textured liner surface to reduce friction and enhance joint mobility. The liners can be customized using 3D scanning and additive manufacturing techniques to create a personalized fit for each patient.
Novelty and Inventive Step
The new claims introduce a modular design with interchangeable liners, a locking mechanism, and advanced features such as sensors and self-lubricating surfaces, which are not present in the original patent. The inventive step lies in the combination of these features to create a more efficient, safe, and customizable hip replacement system.
Alternative Embodiments and Variations
Alternative embodiments of the inventive concept could include different locking mechanisms, such as snap-fit or screw-based designs. The system could also be adapted for use in other joint replacement surgeries, such as knee or shoulder replacements. Additionally, the use of different materials, such as ceramic or polyethylene, could provide alternative embodiments with distinct advantages.
Potential Commercial Applications and Market
The modular acetabular cup system has significant commercial potential in the hip replacement market, which is projected to grow significantly in the coming years. The system's advanced features and customizable design make it an attractive option for surgeons and patients seeking improved outcomes and reduced recovery times. The target market includes orthopedic device manufacturers, hospitals, and surgical centers.
