  • Publication number: 20200289168
    Abstract: A polyaxial screwdriver for inserting a bone screw in a vertebra. A polyaxial bone screw assembly includes a coupling element. When a screw engaging end of the polyaxial screwdriver is lowered on the head of the bone screw, the complimentary surfaces of the screw engaging end of the screwdriver and the head of the screw self-align. A ratchet mechanism formed in the screwdriver provides progressive and automatic locking of the polyaxial screwdriver to the coupling element and prevents the accidental unthreading from the coupling element. In another embodiment of the polyaxial screwdriver, a collet slides over the outside surface of the upper end of the coupling element and locks on to the coupling element. In yet another embodiment of a polyaxial screwdriver, the outer sleeve of the polyaxial screwdriver has a split end that securely engages the coupling element.

  • Publication number: 20200178947
    Abstract: An insertion instrument is configured to eject at least one anchor body into respective target locations, and subsequently apply a predetermined tensile force at least one actuation member of the at least one anchor member so as to actuate the at least one anchor body from a first configuration to a second expanded configuration. The insertion instrument can include a tension assembly that applies the predetermined tensile force to the at least one actuation member. The predetermined tensile force can be defined by a distance of travel, a predetermined failure force of a fuse, or a combination of distance of travel and a predetermined failure force of a fuse.

  • Patent number: 8372118
    Abstract: An implantable spinous process fixation device includes an elongated component, top and bottom pivoting wing components, arranged opposite and parallel to the elongated component and separated from it by a spacer. First and second spinous processes of first and second adjacent vertebras are clamped between a top portion of the elongated component and the top pivoting wing and between a bottom portion of the elongated component and the bottom pivoting wing, respectively, by pivoting the top and bottom pivoting wings toward the top and bottom portions of the elongated component. The clamping of the spinous processes stabilizes the positions of the adjacent vertebras and prevents them from moving relative to each other.

  • Patent number: 8235995
    Abstract: A bone staple (10) for securing a first bone region (12A) to a second bone region (12B) includes a staple body (16) having a first leg section (18), a second leg section (20), and a connector section (22). The first leg section (18) is insertable into the first bone region (12A). The second leg section (20) is insertable into the second bone region (12B). The connector section (22) connects the first leg section (18) to the second leg section (20). The connector section (22) includes a deformable region (22A) that is movable from a first configuration (14A) in which the leg sections (18) (20) are spaced apart a first distance (24) and a second configuration (14B) in which the leg sections (18) (20) are spaced apart a second distance (26) that is less than the first distance (24). In one embodiment, compression of the deformable region (22A) causes the deformable region (22A) to move from the first configuration (14A) to the second configuration (14B).

  • Patent number: 8231660
    Abstract: A spinal fixation element includes a screw and a washer. The screw comprises an elongated body of a first diameter and the body includes a threaded portion at a distal end and a semispherical head of a second diameter at a proximal end. The second diameter is larger than the first diameter. The washer comprises a semispherical through opening of a third diameter at the top, of a fourth diameter in the middle and of a fifth diameter at the bottom. The third diameter is slightly smaller than the second diameter, the fourth diameter is slightly larger than the second diameter and the fifth diameter is smaller than the second diameter. The washer surrounds the semispherical head, is non-removably attached to the semispherical head and is rotatable and positionable at an angle relative to the elongated body.

  • Patent number: 8147531
    Abstract: A compression pin for urging two bone regions together includes a pin body having a distal end, an opposed proximal end, a first threaded region, and a second threaded region. The first threaded region is positioned near the distal end, and the second threaded region is positioned near the first threaded region. The first threaded region includes a first thread having a FT leading surface that is at a FT leading angle, and the second threaded region includes a second thread having a ST leading surface that is at a ST leading angle that is different than the FT leading angle. During insertion of the compression pin, the first threaded region and the second threaded region cooperate to aggressively compress the bone regions together.

  • Patent number: 8048124
    Abstract: A bone screw assembly includes a tulip-shaped seat, a bone fixation device, a ring-shaped washer, a rod and a cap. The tulip-shaped seat comprises a through opening dimensioned to receive the bone fixation device and a horizontal channel dimensioned to receive the rod. The washer is placed into the seat on top of the bone fixation device head and comprises first and second side tabs and a first pair of upward extending projections separated by a first gap and a second pair of upward extending projections separated by a second gap. The side tabs interface with a groove formed in the bottom portion of the seat. The rod is placed within the channel and positioned within a groove formed on the top surface of the washer. The cap includes first and second projections extending downward from its bottom surface and each of the first and second downward projections comprises first and second sidewise extending ridges.

  • Patent number: 8016836
    Abstract: A bone screw driver (12) for inserting a bone screw (14) into a bone region (218A) includes a driver shaft (12B) that selectively engages the bone screw (14). The bone screw (14) includes a screw threaded region (14A) and a screw engagement region (14B). The screw engagement region (14B) includes a screw shaft (14D) and an engager ring (14E). The driver shaft (12B) includes a shaft aperture (322), a first resilient member (324A), and a first shaft projection (326A). The shaft aperture (322) receives at least a portion of the screw shaft (14D), the first resilient member (324A) engages the screw shaft (14D) to inhibit movement of the screw shaft (14D), and the first shaft projection (326A) engages the engager ring (14E) so that rotation of the driver shaft (12B) results in rotation of the bone screw (14).
