Patent number: 11819222Abstract: A disc preparation instrument for use in fusing spinal vertebrae comprises a modular scoring trial and a depth stop releasably attached to the scoring trial. The trial includes an elongate stem supporting a trial device at its distal tip. The trial device is insertable into a disc space and includes a rotatable rasp for scoring opposing vertebral endplates at a scored location. A stop, sized to engage an exterior surface of the vertebrae, is movable on the depth stop stem by rotation of an adjustment knob to a plurality of selectable distances between the proximal end of the trial device and the movable stop. An actuator releasably attached to the trial is operable to rotate the rasp. A plurality of modular trials, each having a trial device of different heights may be provided in a kit. Each scoring trial is selectively releasably attachable to a single depth stop.Type: GrantFiled: December 11, 2020Date of Patent: November 21, 2023Assignee: SPINE WAVE, INC.Inventors: Benoit Adamo, David Boisvert, Scott McLean
