Abstract
A robotic prosthesis alignment device is disclosed that may automatically move the alignment of a prosthesis socket in relation to a prosthesis shank. The robotic prosthesis alignment device provides automatic translation in two axes. The robotic prosthesis alignment device includes angulation mechanics that automatically provide for plantarflexion, dorsiflexion, inversion, and eversion of the foot and shank with respect to the prosthesis socket. A surrogate device is also disclosed that can replicate the alignment achieved with the robotic prosthesis alignment device.
Claims20
A combination including a robotic prosthesis alignment device and a surrogate device, comprising:
- a robotic prosthesis alignment device, comprising:
- an angulation assembly comprising a first wedge and a second wedge, each wedge being separately capable of rotation;
- and
- a first and second driver motor to rotate the first and second wedges, wherein the device provides an indication of the positional relationships of the first and second wedges with respect to each other that represents an angle of tilting;
- and
- a surrogate device separate from the robotic prosthesis alignment device, comprising:
- a third wedge comprising marks, wherein the marks are determinative of a position on the third wedge;
- and
- a fourth wedge comprising marks, wherein the marks are determinative of a position on the fourth wedge, wherein the third and fourth wedges are rotationally positionable with respect to each other, wherein when a mark of the third wedge is in alignment with a mark on the fourth wedge in accordance with the indication provided by the robotic prosthetic alignment device, the same angle of tilting results as is in the robotic prosthesis alignment device.
