Abstract: The disclosure provides apparatus and methods of use pertaining to a bidirectional biomechanical prosthetic finger assembly. One embodiment includes a metacarpophalangeal (MCP) pivot configured for swivelable attachment to a hand of a user, a distal coupler, and an articulation assembly rotatively coupled therebetween. A multiple-finger ring configured to receive a user's residual finger and at least one adjacent finger is disposed upon the articulation assembly, and may be adjusted to a target location based on a length of the residual finger. The articulation assembly is configured to utilize vertical movements of the residual and/or adjacent finger(s) within the multiple-finger ring to articulate the distal coupler within a plane parallel to an x-z plane, and the MCP pivot is configured to utilize lateral movements of the residual finger within the ring to articulate the distal coupler within a plane parallel to an x-y plane. Other embodiments are also disclosed.

Abstract: The disclosure provides apparatus and methods of use pertaining to a biomechanical finger brace assembly. In one embodiment, the assembly includes a coupling tip, a proximal ring configured to concentrically receive a user's finger, a distal ring configured to concentrically receive the finger, and a rocker formed in an H-shape. The distal ring and the rocker are pivotally suspended between a proximal coordinated pivot point anchored on the proximal ring and a distal coordinated pivot point anchored on the coupling tip, such that movements of the finger within the proximal ring articulate the distal ring together with the rocker to articulate the coupling tip. The coupling tip may include an open end or an enclosed recess to accept a minimally-amputated or non-amputated finger. Other embodiments are also disclosed.
