Adaptive Spinal Fusion System
Legal Citation
Summary of the Inventive Concept
A next-generation spinal fusion system that incorporates adaptive locking mechanisms, bio-absorbable materials, and integrated sensors to provide optimal fixation and minimize complications.
Background and Problem Solved
The original patent's locking screws may not account for changes in the bone plate's mechanical properties over time, leading to potential screw backout or fixation failure. The new inventive concept addresses this limitation by introducing adaptive locking mechanisms that adjust to the degradation of the bone plate, ensuring secure fixation of the vertebral bones.
Detailed Description of the Inventive Concept
The adaptive spinal fusion system comprises a bio-absorbable bone plate designed to degrade over time, and a locking mechanism that adapts to the degradation of the bone plate. The locking mechanism may include sensors that monitor the implant's mechanical properties and adjust the locking force accordingly. Additionally, the system may incorporate artificial intelligence to predict and adapt to changes in the implant's mechanical properties, ensuring optimal fixation and minimizing the risk of complications. The system may also include interchangeable bone plates with varying geometries and material properties, allowing for customized vertebral fusion procedures.
Novelty and Inventive Step
The new claims introduce a paradigm shift in spinal fusion technology by incorporating adaptive locking mechanisms, bio-absorbable materials, and integrated sensors. These features provide a significant improvement over the original patent's locking screws, which may not account for changes in the bone plate's mechanical properties over time.
Alternative Embodiments and Variations
Alternative embodiments of the adaptive spinal fusion system may include using different types of sensors, such as strain gauges or accelerometers, to monitor the implant's mechanical properties. Additionally, the system may incorporate machine learning algorithms to predict and adapt to changes in the implant's mechanical properties. Other variations may include using different materials for the bone plate, such as titanium or ceramic, or incorporating additional features, such as antibiotic coatings or growth factors, to promote bone growth and fusion.
Potential Commercial Applications and Market
The adaptive spinal fusion system has significant commercial potential in the orthopedic and spinal implant industries, with potential applications in cervical and lumbar spinal fusion procedures. The system's ability to provide optimal fixation and minimize complications may reduce healthcare costs and improve patient outcomes, making it an attractive solution for hospitals and healthcare providers.
