    • A Gigli saw used by a surgeon to cut bones is constructed of a plurality of round wires which have been deformed in a coining stand so that they form one polygonal shape which in the preferred embodiment is square. This square strand is then twisted along its own axis in a given direction of lay. It is then heat-treated for stress relief and a plurality, such as three, of such strands are twisted together to form a cable. This results in a Gigli saw blade with many cutting edges formed at the edges of the polygon as each such edge is presented at the periphery of the cable. Preferably, the strands have a different number of twists from that of the cable, and are twisted in the opposite direction so that the cutting edges lie at about 5 to 15 degrees relative to the longitudinal axis of the cable. The foregoing abstract is merely a resume of one general application, is not a complete discussion of all principles of operation or applications, and is not to be construed as a limitation on the scope of the claimed subject matter.
    • 由外科医生切割骨头使用的Gigli眼镜由多个圆形线构成,这些圆形线已经在压花架中变形,使得它们形成一个多边形形状,在优选实施例中是圆形的。 然后将该方形股沿其自身的轴线在给定的铺设方向上扭曲。 然后对其进行热处理以消除应力,并且将诸如三个这样的股线的多个扭绞在一起以形成电缆。 这导致了一个Gigli锯片,其中形成有多个切割边缘,因为每个这样的边缘呈现在电缆的外围。 优选地,股线具有不同于电缆的扭曲数量,并且在相反方向上扭转,使得切割边缘相对于电缆的纵向轴线处于约5至15度。 上述摘要仅仅是一般应用的简历,不是所有操作原理或应用的完整讨论,并不被解释为对所要求保护的主题的范围的限制。
