  • Patent number: 12121233
    Abstract: Systems and methods for tibial plateau leveling osteotomy (TPLO) are disclosed. According to some embodiments, an osteotomy method may include cutting a tibia with an arcuate cut to separate a tibial plateau of the tibia from a tibial base of the tibia, rotating the tibial plateau relative to the tibial base from a first orientation to a second orientation, and, with the tibial plateau in the second orientation relative to the tibial base, securing an implant to the tibia to secure the tibial plateau to the tibial base. Securing the implant to the tibia may include embedding a first leg of the implant into the tibial base, and embedding a second leg of the implant into the tibial plateau such that the first and second legs apply compression urging the tibial plateau toward the tibial base.

  • Publication number: 20240164814
    Abstract: Various multiaxial receivers for receiving at least one tether are disclosed. A multiaxial receiver may include a body having a U-shaped cavity configured to receive a longitudinal rod therein and a lower cavity configured to couple to a pedicle screw. The body may include a first aperture extending through a side surface of the body and defining a first passageway configured to permit a tether to pass therethrough in the horizontal direction. In some embodiments, the body may include a second aperture extending through the side surface of the body and defining a second passageway configured to permit the tether to pass therethrough in the horizontal direction. A set screw may be configured to be rotated from an open position in which the tether is permitted to pass through the first passageway and optionally through the second passageway to a closed position in which the tether is immobilized.

  • Patent number: 11877775
    Abstract: A multiaxial receiver may include a body having a U-shaped cavity configured to receive a longitudinal rod therein and a lower cavity configured to couple to a pedicle screw. The multiaxial receiver may include a first passageway configured to permit a tether to pass therethrough in the vertical direction. In some embodiments, the multiaxial receiver may also include a second passageway configured to permit a tether to pass therethrough in the horizontal direction. An immobilization assembly including a set screw and a wedge may immobilize the tether. The immobilization assembly may be configured to be rotated from an open position in which the tether is permitted to pass through the first passageway to a closed position in which the tether is immobilized within the first passageway or second passageway by pining the tether against a bearing surface of the first passageway.

  • Publication number: 20220409289
    Abstract: An intraoperative ultrasound imaging system and method capable of using ultrasound imaging to safely place a surgical access instrument (e.g. guide wire, dilator, cannula, etc.) through a tissue (e.g., muscle, fat, brain, liver, lung, etc.) without damaging nearby neurovascular structure is described herein. The intraoperative ultrasound system includes an ultrasound probe assembly configured for emitting and receiving ultrasound waves and a computer system including a processor and a display unit. Once the probe is in position, ultrasound imaging is performed wherein the computer receives RF data from the probe and causes a B-mode image of the visible anatomical structures (e.g. muscle, bone, etc.) to be displayed on the display unit.

  • Patent number: 10278741
    Abstract: A translating polyaxial bone anchor for anchoring a connecting rod to a spinal vertebra comprises a fastener having a bone engaging portion and a head, the head defining a socket. An insert is captively retained in the socket and configured for swiveling polyaxial movement therein. The insert includes an elongate connecting element defining an axis, the connecting element projecting outwardly from and through the socket. A yoke having at one end a rod receiving channel for receiving a connecting rod is coupled to the fastener by a coupling member. The coupling member couples the yoke to the insert connecting element for joint polyaxial movement relative to the fastener and for translational movement of the yoke in a direction transverse to the axis of the connecting member. A fastening element is supported by the yoke for securing the connecting rod between the fastening element and the coupling member.
