  • Patent number: 11045226
    Abstract: A screw element includes a screw axis, a shank for inserting in a bone, and a drive portion for engaging a screw driver. The drive portion includes a first wall defining a first recess and a second wall defining a second recess. Drive grooves are formed in the first wall and extend parallel to the screw axis. The second wall extends axially from a free end portion of the screw element to the first wall and has an inner diameter that continuously increases from the first wall towards the free end portion. A plurality of guide grooves are formed in the second wall at circumferential positions corresponding respectively to circumferential positions of the drive grooves. The guide grooves extend further radially from the screw axis than the drive grooves and guide the screw driver from the free end portion of the screw element to the drive grooves.

    Abstract: Spinal plates with additional features to improve the stability of the interface between the plate and the underlying bone. A bone plate may include one or more sharp ridges along the periphery of its underside. When attached to bone, the ridge digs into the bone and increases stability. A bone plate may alternatively or additionally include one or more holes for optional spikes, which may be inserted once the plate is attached to the bone. By separating the spikes and including them as an optional component, the plate may enhance stability while reducing or eliminating the chance of the spike injuring the patient. Furthermore, bone screws may incorporate alternating notches and ridges into the head of the screw. The notches and ridges may interface with a set screw, thereby preventing rotation and loosening of the screw.

  • Patent number: 9962759
    Abstract: A screw includes a head having a top surface where a drive socket and drive regions are recessedly formed. Each drive region has two non-parallel side walls and two different drive walls. One drive wall is connected to the side walls to form a groove communicating with the drive socket. The other drive wall is connected between two adjacent side walls of two adjacent grooves. At least one of the drive walls slopes downwards from the top surface at a slope of at least 1 degree. Each side wall connecting between the drive walls deviates inwards by an angle difference of at least 1 degree. The slope and the inward deviation of the walls receive a driving tool firmly to prevent a swinging problem and enhance the torque transmission.

  • Patent number: 9261127
    Abstract: A fastener comprising a fastener body and a fastener head is disclosed. The fastener body has a threaded portion and defines a longitudinal axis. The fastener head is arranged at one end of the fastener body, and comprises a tool engaging portion. The tool engaging portion comprises a plurality of alternating lobes and flutes forming a multilobular surface pattern, each lobe having a driven surface arranged to engage with a driving surface of a tool, and a trailing surface arranged opposite to the driven surface. The driven surface and the trailing surface extend substantially parallel to the longitudinal axis defined by the fastener body. The trailing surface of at least one lobe is provided with a modified zone in which a diameter of the lobe is increased, said modified zone providing a wedging effect between the tool engaging portion and a tool. In the fastener of the invention wobble between the fastener and a tool is significantly reduced.

  • Patent number: 8992151
    Abstract: A tamper-resistant fastener includes a non-circular drive recess optionally with a non-circular center post. Preferably the recess and center post are at least partially ellipsoidal cylinders that are concentric and aligned (i.e. they share a common major axis direction). This configuration forms a slot having preferably a substantially uniform width into which an authorized driver is inserted. The length of the major maximum dimension of the post is selected so that a circular arc tangent to the maximum radius of the post will pass closely to or intersect the minimum radial dimension of the recess.

  • Patent number: 8955417
    Abstract: A design for a rotary drive both for a tool and for a workpiece to be rotationally driven is proposed. This rotary drive design contains a cylindrical basic shape which deviates from a circular cylindrical shape. The contour or the cross section through this basic shape has a plurality of rounded projections and rounded recesses arranged between said projections. The projections tangentially touch a circle having a maximum radius, while the recesses, for their part, tangentially touch a circle having a minimum radius. Deviating from this cylindrical basic shape, in the regions between the projections are configured conical surfaces, which are not instrumental in the transmission of torques, but take care of centering and alignment between the tool and the workpiece.

  • Publication number: 20140360123
    Abstract: A fastener assembly for connecting a non-load bearing wall to a truss comprises a fastener with a sleeve retained on the fastener and axially displaceable along the fastener. The fastener has unthreaded shank portion and the sleeve is disposed about the unthreaded shank portion. The sleeve has a length less than the axial length of the unthreaded shank portion. The fastener assembly is employed to form a truss/non-load bearing wall connection system, wherein the non-load bearing wall is disposed below the truss and has a top plate with at least one bore. A fastener assembly is disposed in each bore and threaded into the truss so that a gap is formed between the truss and its top plate. Upon deflection of the truss, one or more fasteners vertically slide axially relative to its associated sleeve.
