  • Above and below knee prosthesis—leg coupler
    Patent number: 6893468
    Abstract: A device to couple a prosthesis to a human leg stump above-the-knee in a first embodiment, and below the knee in the second embodiment. The device has an upper and a lower plate, the connecting mechanism being disposed in the lower plate. The upper plate is round and the same in both embodiments, but for above-the-knee junctions, the lower plate is elliptical while for below-the-knee junctions, the lower plate is round and of the same diameter as the upper plate. The operative connection is achieved by use of a guillotine, whose horizontally disposed blade engages one of a plurality of grooves on a locking stud. The movement of the spring-loaded guillotine is controlled by a retractable release pin to permit the guillotine to engage in or disengage the groove to which is disposed.
