This technical disclosure describes improvements that would be readily apparent to a Person Having Ordinary Skill In The Art (PHOSITA) when considered in combination with the foundational architecture disclosed in U.S. Patent No. 11,857,419.

Summary of the Inventive Concept

An improved graft collar system for facilitating grafting in surgical procedures, offering adjustable diameter, reinforcement structures, and self-locking mechanisms to enhance mechanical strength, ease of use, and secure engagement with load-bearing bone fasteners.

Background and Problem Solved

The original patent disclosed a graft collar for facilitating grafting in surgical procedures, but it had limitations in terms of accommodating various bone fastener sizes, mechanical strength, and secure engagement. The new inventive concept addresses these limitations by introducing adjustable diameter, reinforcement structures, and self-locking mechanisms, providing a more efficient, safe, and reliable graft collar system.

Detailed Description of the Inventive Concept

The enhanced graft collar system comprises a graft collar with an adjustable diameter to accommodate various sizes of bone fasteners, a reinforcement structure integrated into the body to enhance mechanical strength, and a self-locking mechanism to prevent disengagement of the graft collar from the bone fastener. The system also includes a load-bearing bone fastener with a convexly shaped lower surface, and a method for securely engaging the graft collar with the bone fastener. The adjustable diameter feature allows for a more universal fit, while the reinforcement structure and self-locking mechanism ensure a more secure and reliable engagement.

Novelty and Inventive Step

The new claims introduce novel features such as adjustable diameter, reinforcement structures, and self-locking mechanisms, which are not present in the original patent. These features provide a non-obvious solution to the limitations of the original patent, offering improved mechanical strength, ease of use, and secure engagement.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include varying the design of the reinforcement structure, using different materials for the graft collar and bone fastener, or incorporating additional features such as sensors or actuators to enhance the system's functionality. Variations could also include adapting the system for use in different surgical procedures or anatomical regions.

Potential Commercial Applications and Market

The enhanced graft collar system has significant commercial potential in the medical device industry, particularly in the areas of orthopedic, neurosurgical, and cardiovascular surgery. The system's improved features and functionality could attract a wide range of customers, including hospitals, surgical centers, and medical device manufacturers.
