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.

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.

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 an H-shape with a first end forming a first split prong and a second end forming a second split prong may extend between the coupling tip and the proximal ring. The coupling tip, distal ring, proximal ring, and H-shaped rocker may all be hingedly connected such that movements of the residual finger within the proximal ring articulate the distal ring together with the rocker to articulate the coupling tip. Other embodiments are also disclosed.

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.
