Abstract
An interface for use in conjunction with a prosthetic device is formed of a pliable material which is configured to support the necessary connection to a residual limb when used. The interface further has an internal surface structure that includes several stepped indentations which provide a more efficient and effective product. The stepped indentations have a dimension which decreases as the distance from the interior surface increases. In some embodiments, the indentations are shaped as an octagon, with each step also being octagonal. Other shapes are also contemplated. Also, the steps of the indentations could be uniform or irregular.
Claims14
An interface for use in a prosthetic limb, comprising:
- a layer of interface material custom formed to fit a residual limb of a patient, the interface material having a plurality of perforations therein designed to accommodate a vacuum seal between the residual limb and a socket of a prosthetic limb, the perforations extending inwardly from an outer surface of the interface material to an inner surface;
- wherein each perforation has a stepped profile with a plurality of steps, with the cross sectional width of each perforation getting smaller moving away from the inner surface of the interface material toward the outer surface.
An interface for use with a custom designed prosthetic limb to provide attachment to a residual limb of a user, the interface comprising:
- a custom fit layer of interface material configured to surround and capture the residual limb, the interface material having a plurality of perforations therein designed to accommodate a vacuum seal between the residual limb and a socket of the prosthetic limb, the perforations extending inwardly from an outer surface of the interface material to an inner surface;
- wherein each perforation is octagonal in shape with a stepped profile having a plurality of steps, with the cross sectional width of each perforation getting smaller moving away from the inner surface of the interface material toward the outer surface, thus causing an opening in the outer surface being smaller than the opening in the inner surface, the perforations helping to accommodate the vacuum seal by increasing surface area.
