TF-I, interface, suction socket, combined with liner


Interface as addition to a trans-femoral amputation prosthesis which is a suction socket design to be combined with a liner. The suspension is based on suction. The socket is made to extremely close tolerances and is suspended by suction. A special one way valve is placed into a distal area of the socket. The valve controls the pressure as well as the vacuum and keeps that within values that oedema does not occur.
The fitting can be based on two principles or be hybrid type:
* a narrow medial/lateral (NML) principle. It encapsulates the ischium in its design supported by a rigid structural frame.
* a quadrilateral shape of the socket
* a hybrid shape between quadrilateral and NML.
The final fitting depends on the:
* the length of the stump
* the shape of the stump
* the skeletal structure of the pelvic area.
The socket may be made from wooden, acrylic resin or thermoplastic.
The socket has to be combined with a liner. See elsewhere in the Nomenclature for liner details.
