Abstract: The disclosure provides apparatus and methods of use pertaining to a prosthetic finger assembly. In one embodiment, the assembly includes a coupling tip and a distal ring coupled with the coupling tip. The assembly further includes a proximal ring coupled with the distal ring. A rocker formed in a Y-shape with a first end forming a single prong and a second end forming a split prong may extend between the coupling tip and the proximal ring. The coupling tip, distal ring, proximal ring, and Y-shaped rocker may all be hingedly connected such that movements of the residual finger within the proximal ring and the distal articulate the distal ring together with the rocker to curl and bend the coupling tip. Other embodiments are also disclosed.

Abstract: The disclosure provides apparatus and methods of use pertaining to a bidirectional biomechanical prosthetic finger assembly. In one embodiment, the assembly includes an eccentric metacarpophalangeal (MCP) pivot configured for swivelable attachment to a hand of a user, a distal coupler, and an articulation assembly rotatively coupled therebetween. A ring configured to receive a user's residual 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 finger within the 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 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: There is disclosed a prosthetic thumb assembly. In an embodiment, the assembly includes a distal phalanges. The assembly includes a proximal phalanges having an operable connection with the distal phalanges. The assembly includes a thumb strap ring having an operable connection with the distal phalanges. The assembly includes a proximal phalanges yoke having an operable connection with the thumb strap ring. The assembly includes an anchoring portion having an operable connection with the thumb strap ring. Other embodiments are also disclosed.

Abstract: There is disclosed a prosthetic full finger assembly. In an embodiment, the assembly includes a distal phalanges. The assembly further includes a middle phalanges having an operable connection with the distal phalanges. The assembly includes a proximal phalanges ring having an operable connection with the middle phalanges. The assembly includes a proximal phalanges yoke having an operable connection with the proximal phalanges ring. The assembly includes a metacarpal back plate having an operable connection with the proximal phalanges yoke and an operable connection with the proximal phalanges ring. The assembly includes an anchoring portion having an operable connection with the metacarpal back plate at a location proximal of the operable connection of the proximal phalanges ring. Other embodiments are also disclosed.

Abstract: A prosthetic finger that is able to provide independent natural movement to mimic a real finger. The present invention utilizes unique connections to provide users with natural movement and restore their ability to perform activities that require the full dexterity of their hands. Additionally, the present invention also allows users to interact with touch screens that normally would not work due to the insulating properties of other traditional prosthetic fingers.
