  • Patent number: 9936989
    Abstract: A bone support fixating device with a longitudinally slotted hip screw which permits operative compression of the fracture and holds this compression yet allows sliding as further compression of the fracture occurs under forces of weight bearing; comprising a hollow cylindrical shaft with a screw portion at its upper proximal end and four equally spaced longitudinal grooves at its lower distal end, having three equally distant angled holes between the ends, through which three wires can be inserted, the three ‘elastic’ proximally curved wires, welded, glued or crimped distally, can be inserted into the hip screw collectively called the ‘tri-wire’; The proximal end has the wires curved outward, with all three wires equally spaced; upon pushing the tri-wire into the hip screw, the wires goes through the angle holes in the hip screw and provides three projections equally spaced; which improves the rotational stability of the proximal fracture fragment.

  • Patent number: 5489178
    Abstract: An anchor bolt is provided having a shank which is retained within a recess via peak to peak reaction forces rather than a plurality of peak to base arrangements. This is accomplished through the use of one or more continuous "S" bends or undulations intermediate the shank ends. The "S" bends each create two peaks which extend outwardly from the shank surface with a continuous curve therebetween. That curve includes an inflection point, preferably on the longitudinal axis of the shank, but the slope of the curve at the inflection point is not parallel to that longitudinal axis. Thus, when the shank is inserted within the recess compressive pressure applied to one such peak is directly opposed by such forces applied to the other peak. These peaks can be disposed on opposite sides of the shank or, for example, disposed in a helical or other such pattern about three or more sides of the shank. Serration and/or an abrasive surface can also be provided on the shank to increase retention.

    Abstract: A method for treating a nail in order to increase the withdrawal load required to withdraw the nail from a piece of timber into which it has been driven. In accordance with the invention the nail is coated with a suspension containing a chelating agent so selected that, upon contact with lignin present in the timber the nail is bonded to the lignin via a chelate bond. The chelating agent comprises a modified polysaccharide in aqueous solution and is provided with a protective colloid to which the chelating agent has a lower affinity than to the lignin present in the timber. The suspension also includes a suspended polymeric thermoplastic resin to which the chelating agent has a lower affinity than to the protective colloid.
