Abstract: An artificial finger assembly includes a residual finger socket adapted to receive a residual finger of the wearer, and a hinge arranged rearwardly of the residual finger socket. The assembly further includes a pair of controlling arms pivotally coupled to the hinge and including a first controlling arm and a second controlling arm coupled to the residual finger socket. A middle finger portion extends forwardly of the socket and is configured to pivot relative to the residual finger socket. The first controlling arm is pivotally coupled to the middle finger portion. A fingertip portion is pivotally coupled to the middle finger portion. A lock assembly is configured to lock the pair of controlling arms together to prevent the pivoting of the controlling arms, the middle finger portion, and the fingertip portion.

Abstract: A digit prosthesis assembly is described. Embodiments of the digit prosthesis assembly include, but are not limited to, an attachment assembly, a thumb assembly, one or more finger assemblies, a pinky finger assembly, a palm engagement assembly, and combinations thereof.

Abstract: Disclosed is an articulated artificial finger assembly, which can be controlled by the remaining portion of an amputated finger. An adjacent finger is used to manipulate the device when no finger is present. When the stump or adjacent finger begins to bend at the first knuckle, the rest of the device will react to the movements and articulate in the natural manner of a human finger. There are two embodiments shown which, can accommodate a variety of cases. The first embodiment relates to an amputated finger with a portion of the finger remaining. The second is used when a total finger is absent. In either case, the first embodiment uses a ring that is placed over the remaining stub of the finger and the second embodiment a ring is placed over an adjacent finger. The ring, in either embodiment, actuates upper and or lower actuation drives, which are reciprocally and transversely attached to a pivoting block. The pivoting block is fastened to an adjustable middle phalangeal section.
