Enhanced Internal Bone Fixation System with Customizable Layers
Legal Citation
Summary of the Inventive Concept
An improved internal bone fixation system featuring adjustable layers for customized bone region fit, enhanced bone growth, and tissue integration.
Background and Problem Solved
The original internal bone fixation device had limitations in terms of adaptability to varying bone geometries and promoting bone growth. The new inventive concept addresses these limitations by introducing a support frame with customizable layers, allowing for a precise fit in specific bone regions, and incorporating a porous architecture infused with bone growth-promoting materials.
Detailed Description of the Inventive Concept
The enhanced internal bone fixation system consists of a support frame comprising adjustable layers, each layer having an inner rim and an outer rim connected by rim struts. The layers can be customized to fit specific bone regions, ensuring a precise and secure fit. The system also features a porous architecture within the support frame, which is infused with a bone growth-promoting material to enhance bone fusion. Additionally, the outer surface of the device can be coated with a biocompatible material that promotes tissue integration. The system can be used in conjunction with a kit comprising the internal bone fixation device and a set of tools for customizing the layers of the support frame.
Novelty and Inventive Step
The new inventive concept's novelty lies in the introduction of customizable layers, allowing for a precise fit in specific bone regions, and the incorporation of a porous architecture infused with bone growth-promoting materials. These features provide a significant improvement over the original patent, offering enhanced bone growth and tissue integration.
Alternative Embodiments and Variations
Alternative embodiments of the inventive concept could include varying the material composition of the support frame, modifying the porous architecture to accommodate different bone growth-promoting materials, or incorporating sensors to monitor bone growth and device performance.
Potential Commercial Applications and Market
The enhanced internal bone fixation system has significant commercial potential in the orthopedic and spinal implant markets, offering a more effective and efficient solution for bone fusion and tissue integration. The system's customizable nature and ability to promote bone growth make it an attractive option for surgeons and medical professionals seeking to improve patient outcomes.
