  • Patent number: 10758277
    Abstract: An anchor assembly for use in spinal fixation to interconnect a longitudinal spinal rod with a patient's vertebra. The anchor assembly preferably includes a bone anchor, a body with a rod-receiving channel, an insert member (preferably a bushing), and a locking cap. The anchor assembly enables in-situ assembly where the bone anchor may be secured to the patient's vertebra prior to being received within the body of the bone anchor assembly. Accordingly, the anchor assembly enables a surgeon to implant the bone anchor without the body to maximize visibility and access around the anchoring site. Once the bone anchor has been secured to the patient's vertebra, the body may be snapped onto the bone anchor and a spinal rod may be inserted into the rod-receiving channel.

  • Patent number: 9011450
    Abstract: A surgical instrument for positioning a rod includes a rod holder, a sleeve, and a pusher rod. The rod holder is configured to releasably grip a first end of a rod therebetween. The sleeve is disposed about the rod holder and slideable between an extended position to hold the tines in a rod gripping position and a retracted position to permit release of the rod from the tines. The pusher rod is slidably disposed within the rod holder and has a plurality of rod receiving notches configured to engage the rod such that the rod is held at a selected angle with respect to the pusher rod.

  • Patent number: 8808296
    Abstract: A method for performing spinal fixation and instrumentation. A first incision may be made through the skin and a passageway may be created to the spine. A screw may be inserted through the passageway and into a vertebrae. The screw may have a head portion including a channel. An insertion guide may be operable connected to the screw. The insertion guide may have first and second longitudinal slots. Additional screws may each be inserted through separate incisions or through the first incision. Insertion guides may be operably connected to a head portion of each screw. A sleeve may be positioned into one insertion guide in a first position to guide a rod through at least one other insertion guide. The sleeve may be rotated to a second position to allow the rod to move down the slots of the insertion guide(s) and into the head portion of the screw.
