BIO-MECHANICAL PROSTHETIC FINGER WITH H-SHAPED ROCKER

摘要

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.

主权项

1. A biomechanically driven prosthetic finger assembly, comprising:
a distal ring rotatively coupled between a coupling tip and a proximal ring via respective first and second hinged connections; and a rocker rotatively coupled between the coupling tip and the proximal ring via respective third and fourth hinged connections, wherein: the first and second hinged connections define a midline relative to a z-axis; the third hinged connection is located below the midline; and the fourth hinged connection is located above the midline, such that a relative rotational motion between the proximal ring and the distal ring causes a relative rotational motion between the distal ring and the coupling tip to emulate a finger's natural closing motion.
