  • Patent number: 10980577
    Abstract: A surgical instrument for correcting spinal deformities includes a tubular body adapted to receive a second instrument through the tubular body. The tubular body forms a transverse passage adapted to receive a longitudinal fixation element through the tubular body. The tubular body further includes first and second arms for connecting the surgical instrument to a vertebral anchor. The first and second arms include one or more anti-splaying features adapted to mate with anti-splaying features on the second instrument to prevent the first and second arms from splaying as the second instrument is inserted into the tubular body.

  • Patent number: 10893894
    Abstract: A transverse coupling for connecting multiple implant extensions includes at least a first sleeve and a second sleeve. The first sleeve defines a first aperture adapted to axially receive a first implant extension through the first aperture. The second sleeve defines a second aperture adapted to axially receive a second implant extension through the second aperture. The transverse coupling also includes a central housing. A first shaft connects the first sleeve to the central housing, and a second shaft connects the second sleeve to the central housing. The central housing includes at least one joint for connecting the central housing to at least one of the first and second shafts in a movable arrangement that allows the shaft(s) to move through one or more degrees of freedom relative to the central housing.

  • Patent number: 10201432
    Abstract: A vertebral body replacement device includes a body member and a central rod member having two threaded portions and configured to be operatively associated with the body member. The device also includes a first end member and a second end member with the end members configured to threadingly engage the threaded portions of the central rod member. The body member and the two end members are further constructed to inhibit rotational movement of the two end members when the device is positioned within a space within a spine as the two end members will engage the adjacent respective vertebral bodies following rotational actuation of the central rod member causing the end members to move in an axial direction relative to the body member, thereby allowing the two end members to apply a force to the two vertebral bodies. A surgical instrument and method for using the device are also disclosed.

  • Patent number: 9775654
    Abstract: A surgical ratchet tool and system along with associated methods are disclosed. The surgical ratchet tool can include a relatively simple encompassing member that included a pawl extending into the opening for directly contacting a nut during surgery. The ratchet tool and system can be used for various types of surgery in which easy sterilization and a reduced profile for a ratchet tool is desired. For example, the ratchet tool can be used during surgery for adjustment of a spinal implant, where manipulation of a nut located on a downtube connected to a screw and/or spinal rod is desired. The encompassing member and pawl can be constructed/molded as a single piece unitary structure. A first handle and possibly a second handle can extend from an outer periphery of the encompassing member.

  • Patent number: 9265533
    Abstract: A spinal rod persuader, system and method can include an outer tube, an inner tube, and a locking element. A first actuation mechanism can be movable in a linear fashion along a longitudinal axis direction to cause the locking element to move in a linear fashion over the inner tube and to lock the inner tube onto a pedicle screw. A second actuation mechanism can be rotated to cause the outer tube to move in a longitudinal axis direction with respect to the inner tube to push the spinal rod into a final position with respect to the pedicle screw while the pedicle screw is locked to the inner tube. A slot and/or tab structure can be provided in the outer tube such that actuation of the slot/tab will allow disassembly of the inner tube, outer tube and locking element with respect to each other.

  • Patent number: 9220600
    Abstract: A knee prosthesis having a femoral component with two condyles, an opening disposed between the two condyles, and a tibial component having bearing surfaces to engage and support each of the femoral component condyles. Moving the femoral and tibial components in flexion from about 0° to about 165° causes medial pivot rotation of the femoral component upon the tibial component. Rotation may be caused by interaction between an asymmetrical cam extending between the femoral condyles and a post disposed between the bearing surfaces and extending superior from the tibial component. Rotation may alternatively be caused by asymmetrical medial and lateral condyles which translate posteriorly upon respective medial and lateral bearing surfaces at disparate rates, without a femoral cam, a tibial post, or a post/cam contact surface. Embodiments of the knee prosthesis may be used in cruciate-substituting or cruciate-retaining procedures. Embodiments of the knee prosthesis may also prevent roll forward.
