Enhanced Differential Compression Bone Screw System

An advanced bone compression screw system with improved features, including torque limiting mechanisms, self-tightening mechanisms, and real-time compression force feedback, enhancing the efficiency, safety, and effectiveness of bone compression procedures.

The original differential compression bone screw patent (USPTO Patent No. [insert patent number]) addressed the need for efficient bone compression, but had limitations in terms of over-tightening risks, manual tightening efforts, and lack of real-time compression feedback. The present inventive concept solves these limitations by introducing a system with torque limiting, self-tightening, and compression force sensing capabilities.

The enhanced bone compression screw system comprises a bone compression screw with a shank and a head portion, and a driver tool configured to engage with the head portion. The driver tool includes a torque limiting mechanism to prevent over-tightening of the bone compression screw. Additionally, the bone compression screw may feature a self-tightening mechanism, such as a ratcheting mechanism, to tighten the screw as the bone portions compress. Furthermore, the system may include a sensor configured to detect the compression force applied to the bone compression screw, providing real-time feedback to the user. This allows for optimized compression and reduced risk of over-tightening.

The new claims introduce the concepts of torque limiting, self-tightening, and real-time compression force feedback, which are not present in the original patent. These features address the limitations of the original patent and provide a significant improvement in the efficiency, safety, and effectiveness of bone compression procedures.

Alternative embodiments may include different torque limiting mechanisms, such as friction-based or electronic torque limiters. The self-tightening mechanism could be replaced with a motorized or hydraulic tightening system. The compression force sensor could be integrated into the bone compression screw or the driver tool. These variations would allow for a broader range of applications and customization options.

The enhanced bone compression screw system has significant commercial potential in the orthopedic and spinal implant markets, where efficient and safe bone compression is crucial. The system could be marketed to hospitals, surgical centers, and orthopedic clinics, offering a competitive advantage in terms of safety, efficiency, and patient outcomes.
