Three key technological innovations provide SwissLeg with a significant competitive advantage over competitors: the materials used, the casting and alignment process, and the thermo? molding technique.
1. The Materials:
SwissLeg is a structurally robust artificial leg made of a patentable co?polymer mix. When heated the co?polymer is pliable and can be easily molded to proper shape. When cooled, the co?polymer is highly resistant to warping and is still flexible to be comfortable. The proper specification of the co?polymer composition ensures strength, flexibility and lightness of the final product. An additional consequence of the co?polymer used is the structural attributes of the SwissLeg technology, in sharp contrast to other prosthetic legs that traditionally use polymers for cosmetic purposes only.
2. The Casting and the alignment process:
SwissLeg integrates the prosthetic leg’s alignment in its design from the start. The prosthetic alignment of an artificial leg significantly influences the functional qualities of the prosthesis and the final quality of the fitting. Conventional technologies (traditional pre?cast prosthetic legs) usually conduct the prosthetic alignment as a last step of the fitting process. Most pre?cast technologies either use (1) a three?dimensional alignment bench that fixes the knee joint, while aligning the prosthetic foot, other prosthetic components and the socket, or (2) a laser projector that identifies the body ?s center of gravity line. A last step alignment often requires a significant amount of time, and can be very difficult to achieve with a pre?cast technology composed of multiple moving parts (socket and prosthetic components). The integrated alignment into design leads not only to a better final alignment but also more comfort to amputees than traditional alignment techniques.
3. The Thermo molding technique
SwissLeg uses a thermo?molding technique to mold components together reducing the number of prosthetic components, making the leg lighter, more robust, and less prone to the traditional alignment problems. While thermo?molding has been used in the past with other prosthetic legs, this has only been done for prosthetic legs that have a cosmetic (instead of a structural) purpose.
