Bidirectional biomechanical prosthetic finger assembly
The patent US12070397B2 describes a bidirectional biomechanical finger assembly designed for users with a residual finger. The assembly features an articulation mechanism that includes a multiple-finger ring, which can accommodate both the residual finger and at least one adjacent finger. This ring is selectively positioned on an adjustable ring tendon, which allows for vertical movements of the fingers to facilitate articulation of a distal coupler within a plane parallel to the x-z plane. The design incorporates a proximal coupler and a distal rocker, both of which are rotatively suspended between pivot points, enabling natural finger-like movements. The assembly also includes a hand strap for secure attachment to the user's hand, ensuring stability during use.
Further claims detail the structural components of the assembly, including the presence of multiple abutting rings within the multiple-finger ring and a longitudinal adjustment mechanism that allows for precise positioning of the fingers. The articulation assembly is engineered to emulate the natural articulation of a finger through a series of hinged connections that define a midline relative to the z-axis. This configuration allows for coordinated rotational motion between the components, enhancing the functionality of the prosthetic finger. The design aims to provide a biomechanically driven solution that mimics the natural movement of fingers, thereby improving the user experience for individuals with finger amputations or other residual finger conditions.
