Abstract:
1. A coupler device for connecting a residual limb socket to a lower limb prosthesis comprising: a coupler body having a top mounting surface and a bottom mounting surface and having an anterior area and a posterior area; said top mounting surface connecting said top mounting surface to a residual limb socket at a defined location on said top mounting surface; said bottom mounting surface being adapted to connect said bottom mounting surface to said lower limb prosthesis at a defined location on said bottom mounting surface; said top and bottom mounting surfaces being horizontally offset such that a longitudinal centerline of said residual limb socket is located from about 0.5 to about 4.0 inches anterior of a longitudinal centerline of the lower limb prosthesis when said residual limb socket and said lower limb prosthesis are attached to the top and bottom mounting surfaces, respectively, of the coupler device; said top mounting surface being inclined in the posterior to anterior direction at an angle from about 5° to about 20° relative to said bottom mounting surface; said residual limb socket having a distal end and a proximal end, and said residual limb socket being attached to a sleeve having a proximal end and a distal end housing a receptacle; wherein said coupler body further comprises an aperture on said top mounting surface receiving both an alignment bushing and a pin, said pin comprising a shaft and a series of elevated rings along said shaft and said alignment bushing includes a notch that is sized to fit a dowel pin, and a transverse aperture at the top mounting surface which intersects said aperture of said top mounting surface when said pin is inserted.
