Advanced Bone Screw System with Enhanced Anchoring and Mechanical Properties

The present disclosure relates to an improved bone screw system featuring novel designs and materials to enhance anchoring and mechanical properties, addressing the limitations of existing spinal implant systems.

The original patent disclosed a spinal implant system with a bone screw having a shaft with uniform cross-sectional area, which may not provide optimal anchoring and mechanical properties. The present inventive concept solves this problem by introducing non-uniform cross-sectional areas, variable pitch threads, and porous/trabecular material structures to improve bone screw function.

The advanced bone screw system comprises a shaft with a non-uniform cross-sectional area, proximal and distal portions, and a first thread made from a first material with a variable pitch to enhance anchoring. The system also includes a method for manufacturing the bone screw, involving the creation of a solid core with varied configuration and the application of a layer of material with a specific pattern to enhance mechanical properties. Additionally, the system features internal features configured to optimize bone screw function by increasing rigidity and/or strength, and a tool for inserting the bone screws into a patient's bone. Furthermore, the bone screw may have a porous and/or trabecular material structure to enhance anchoring, and a coating may be applied to increase strength and/or rigidity.

The present inventive concept introduces novel features such as non-uniform cross-sectional areas, variable pitch threads, and porous/trabecular material structures, which are not present in the original patent. These features provide improved anchoring and mechanical properties, making the inventive concept non-obvious and novel compared to the prior art.

Alternative embodiments of the inventive concept may include varying the material composition, thread pattern, and surface roughness to further enhance anchoring and mechanical properties. Additionally, the system may be adapted for use in other orthopedic applications, such as joint replacement or fracture fixation.

The advanced bone screw system has significant commercial potential in the spinal implant market, addressing the need for improved anchoring and mechanical properties. The system may also be adapted for use in other orthopedic markets, providing a broad range of commercial opportunities.
