Enhanced Thigh Prosthetic Component with Dynamic Flexion Adjustment

An improved thigh prosthetic component that enables dynamic adjustment of the maximum flexion of the knee joint, enhancing user comfort and mobility.

The original patent described a thigh prosthetic component with a knee joint that could be pivoted between a stance position and a swing position. However, it lacked a mechanism to adjust the maximum flexion of the knee joint, limiting its versatility and user comfort. The new inventive concept addresses this limitation by introducing a flexion adjustment mechanism, enabling users to customize their knee joint movement.

The enhanced thigh prosthetic component comprises a knee joint upper part and a knee joint lower part operatively connected by a ventral articulated arm and a dorsal articulated arm. The knee joint upper part includes a flexion adjustment mechanism, allowing users to adjust the maximum flexion of the knee joint. This mechanism can be integrated with the dorsal articulated arm, which includes a flexion limiting mechanism. Additionally, the ventral articulated arm and the dorsal articulated arm can be designed to be adjustable in length, enabling dynamic adjustment of the pivot point of the polycentric knee joint.

The new claims introduce a flexion adjustment mechanism, which is not present in the original patent. This mechanism enables dynamic adjustment of the maximum flexion of the knee joint, providing a non-obvious solution to the limitations of the original patent.

Alternative embodiments of the inventive concept could include different types of flexion adjustment mechanisms, such as hydraulic or pneumatic systems. Additionally, the inventive concept could be adapted for use in other types of prosthetic components, such as elbow or ankle joints.

The enhanced thigh prosthetic component has significant commercial potential in the prosthetics industry, particularly in the market for advanced prosthetic limbs. It could be marketed as a premium product, offering users enhanced comfort and mobility.
