Summary of the Inventive Concept
The inventive concept presents a set screw assembly designed for specific, high-demand environments, such as high-altitude, disaster relief, extreme weather, high-security, and limited medical resource situations, ensuring reliable and effective femoral fracture treatment.
Background and Problem Solved
The original patent disclosed a set screw assembly for intramedullary intertrochanteric devices, but it did not address the unique challenges posed by specialized environments. This inventive concept adapts the original design to cater to these specific needs, providing a more reliable and effective solution for femoral fracture treatment in diverse operational environments.
Detailed Description of the Inventive Concept
The set screw assembly comprises a first member with a proximal and distal portion, and a third member insertable into the proximal portion. The new claims introduce specialized features, such as temperature-resistant coatings, waterproof coatings, tamper-evident features, and sterilizable designs, to enable the set screw assembly to function effectively in high-altitude, extreme weather, high-security, and disaster relief environments. The inventive concept also includes a method for treating femoral fractures in areas with limited medical resources, ensuring that the set screw assembly can be successfully implanted and utilized in these settings.
Novelty and Inventive Step
The new claims introduce novel features that adapt the original set screw assembly to specific, high-demand environments, providing a non-obvious solution to the challenges posed by these environments. The inventive concept's unique combination of specialized features and designs enables reliable and effective femoral fracture treatment in a broader range of operational environments.
Alternative Embodiments and Variations
Alternative embodiments of the inventive concept could include additional specialized features, such as shock-absorbing materials, enhanced biocompatibility, or integrated sensors for real-time monitoring. These variations could further expand the range of operational environments in which the set screw assembly can be effectively utilized.
Potential Commercial Applications and Market
The inventive concept has significant commercial potential in the orthopedic industry, particularly in niche markets catering to high-altitude, disaster relief, extreme weather, high-security, and limited medical resource environments. The set screw assembly's adaptability to diverse operational environments makes it an attractive solution for medical professionals and organizations operating in these areas.

Section 103 Obviousness Analysis (PHOSITA)
Field of Art
Orthopedic surgical devices, specifically intramedullary nail fixation systems for femoral fracture treatment, requiring expertise in medical device design, materials engineering, and surgical implant technologies
Person of Ordinary Skill (PHOSITA) Profile
A biomedical engineer or orthopedic surgical device designer with advanced degree, working knowledge of medical device materials, sterilization techniques, and environmental adaptation strategies for surgical implants
Obviousness Rationale
A PHOSITA would recognize that adapting the set screw assembly for specialized environments represents predictable variations using known engineering techniques. The core mechanical functionality of the original set screw assembly remains unchanged, with modifications focused on expanding operational contexts through standard material and coating technologies. These adaptations represent routine design optimization within the medical device engineering domain.
