  • Patent number: 10751241
    Abstract: A surgical leg positioner capable of bending the knee in varus or valgus while simultaneously distracting the tibia from the femur, the leg positioner having a thigh clamp module, a swing arm module connected to the thigh clamp module in a manner that offsets a joint axis laterally to the side of the knee of the patient so as not to damage the opposite compartment of the knee when bent in varus or valgus. The swing arm module also distracts the knee simultaneously when the knee is bent in varus or valgus. The swing arm module also permits flexion and extension of the knee at the knee's natural flexion-extension axis. The surgical leg positioner also utilizes a thigh brace that properly aligns the leg on the surgical leg positioner.

    Abstract: A fixation clamp for use in an external fixation clamp has a clamping assembly having a reception to accommodate a fixation element. The clamp has a locking element extending through the clamping assembly for blocking the position in a defined angular position. A washer is arranged between the locking element and a central opening of the clamping assembly having a cutout extending radially from the through opening such that the washer is mountable and demountable in a radial direction to a locking element longitudinal axis. The cutout has a smaller distance between its sidewalls then the diameter of the through opening. The locking element has circular cross-section below its head portion adapted to fit through the through opening of the washer but larger than the opening of the cutout and has at least one pair of parallel beveled surfaces spaced closer than the distance between sidewalls of the washer cutout.

The coupling includes a plurality of spaced apart flexures located adjacent the coupling aperture. Each flexure includes an axially extending arm portion for engaging a respective part of an inner sidewall portion of the bracket aperture. Upon rotation of the coupling about the central axis, the bracket sidewall portion engages or releases the arms of the coupling to effect radial movement of the arms. In particular, rotation of the coupling in one direction about the central axis relative to the bracket urges the arms radially inward and rotation of the coupling in the other direction permits a radially outward movement thereof.

  • Patent number: 6416268
    Abstract: A taper nut retention device mechanically fastens a plurality of pressure reduction disks. A cage end member at one end of the stacked disks has a series of counterbores, each aligned with respective mounting holes in each disk. A second cage end member at the other end of the stack has a series of inwardly converging, tapered bores with shallow taper angles, each aligned with respective mounting holes and a counterbore. A taper nut with a threaded interior and an outer tapered surface with a shallow taper angle matching the tapered bore is inserted into and engageably contacts the tapered bore. A threaded bolt is inserted into the counterbore and through the disk mounting holes to threadably engage the taper nut. Tightening of the bolt and nut mechanically secures the stacked disk assembly. A process for making the stacked disk assembly wherein each disk and the cage end members are plated with nickel and the components are fused together in a brazing oven.

  • Patent number: 6273646
    Abstract: A tendon 10 is installed in a hole 34 in a mine hanging wall 36 by making use of a barrel 14 and a wedge arrangement 16. One end of the tendon is anchored in the hole 34 such that the other end protrudes therefrom. The barrel 14 is positioned over the protruding end of the tendon 10. A tensioning jack applies a tensile load to the tendon 10 and an oppositely disposed load to a shear ring 20 of the barrel. When the desired preload is reached the shear ring 20 fails permitting the tensioning jack 40 to displace wedge elements 30 of the wedge arrangement 16 inwardly thereby locking the barrel on the tendon and maintaining the desired preload in the tendon.

  • Patent number: 6244806
    Abstract: A locking apparatus includes an inner ring having a tapered outer shape and permitting a bolt of a fastener, with which construction elements are fastened, to pass therethrough, an outer plate formed with a tapered bore which receives the inner ring, a coil spring which urges the inner ring toward the outer plate, and a nut threadedly engaged with the bolt on the side close to an outer end of the coil spring. When an external force is applied to a construction so that the outer plate is displaced toward the nut, together with the construction element associated therewith, the outer plate applies a force, exerting in the direction axially of the bolt, to the inner ring. When receiving the force which has a component directed radially inwardly of the bolt, the inner ring is reduced in diameter to tighten the bolt, thereby preventing a further displacement of the outer plate and the construction element.

  • Patent number: 6234705
    Abstract: The present invention is directed to a transconnector for coupling first and second spinal fixation rods or other elongate fixation elements. The transconnector includes a male member, a female member, and a locking member. The male member has a body with a linking element (such as a hook) associated with the lateral end for receiving one of the fixation elements, and a projection extending from the medial end. The female member has a body with a linking element associated with the lateral end for receiving the other fixation element, and a cavity with an opening on the medial end for receiving a portion of the male member projection. The locking member adjustably and rotatably secures the male member projection portion in the cavity in order to accommodate different orientations and separation distances between the first and second fixation elements.

  • Patent number: 6203051
    Abstract: A base plate is secured to any existing snowboard with screws or bolts through holes in the base plate mating with the standard holes in the snowboard. A rotatable plate has a wide groove to receive a standard existing boot binding and the two have circular openings which fit rotatably over a protruding circular guide post on the base plate. A cap plate with mating holes and a protruding bottom circular plate extends through the boot binding and rotatable plate openings to contact the guide post on the base plate with the screws or bolts passing through all the mating holes to the snowboard. An elevated rim around the cap plate fits within a circular groove of the boot binding to allow the boot binding and rotatable plate to rotate relative to the cap plate. A low-friction ring has bottom teeth to fit within the teeth of the boot binding and a top low-friction top surface to contact the cap plate.

  • Patent number: 6200081
    Abstract: An expansion fastener for hardware elements for furniture comprises an externally ribbed anchor (11) in which an insert (13) is fitted, which insert has a cam surface (14) sliding on a corresponding cam surface (15) in the anchor body for causing a radial expansion of the anchor when the insert is moved by pulling means (16). The insert (13) comprises a fitting end (17) extending radially in a region free from the anchor body and is secured to the pulling means to be susceptible of inclination in the extension direction of said end (17). On axial movement towards the expansion position, the insert slides on the cam surface to receive a thrust for inclination and move said end outwardly of the anchor and towards the pulling direction.

  • Patent number: 6146055
    Abstract: An anchor for a mine roof bolt incorporates a single large rib at the top of a segmented shell. This single large rib is forced into the wall of the bore hole by the downward movement of an associated threaded camming nut during the first few revolutions of the roof bolt. The remainder of the outer surface is generally smooth or unserrated and provides a large bearing surface which is urged against the bore hole wall upon further rotation of the bolt. The camming nut has a specific shape flaring substantially near its upper end such that a relative large area of the bore hole wall below the rib is forced into compression. When fully engaged, the camming nut compresses a tightening washer of a metal alloy softer that the camming nut or the shell. The washer is forced into the threads of the nut thereby preventing loosening of the bolt.
