  • Patent number: 11980398
    Abstract: A crosslink mechanism features a locking clip with interlocking teeth. When being deployed, the surgeon will compress the spring loaded clips, freeing rotation on both sides of the mechanism. Once clipped onto the sequential reducers, the surgeon releases the clips allowing the spring to lock the teeth and therefore lock rotational freedom out of the mechanism.

  • Patent number: 11937857
    Abstract: Bone anchors and surgical instruments (e.g., bone taps, drivers, etc.) are disclosed herein that include integrated guide tips. Use of these anchors or instruments can eliminate one or more of the steps in a conventional bone anchor installation procedure, improving surgical efficiency and safety. For example, a surgical instrument can include a guide projection configured for insertion through a cannulation formed in a bone anchor when the surgical instrument is coupled to the bone anchor. The surgical instrument can also include various mechanisms for adjusting the position of the guide projection relative to the bone anchor. The guide projection can replace the needle, stylet, and guidewire used in typical insertion procedures. The bone anchor can also include integrated tapping features to eliminate the need for a separate bone tap instrument. Thus, in some embodiments, targeting, tapping, and driving the bone anchor can be performed in a single step.

  • Patent number: 11871909
    Abstract: An orthotic device for treating microstomia is described that includes a U-shaped rod, a pair of conformers, and a spring coiled around the rod, positioned between the conformers. The rod includes a curved portion between two straight arms and is sized to accommodate the subject's head. The pair of conformers each include a labial hook and a pair of through holes for receiving the U-shaped rod. The U-shaped rod is smooth through holes of each conformer positioned at the curved portion proximate to a corresponding one of the straight arms. The labial hooks each curve away from the curved portion towards one of the straight arms of the U-shaped rod. During use the labial hooks are inserted in the subject's mouth to engage one of the opposing labial commissures of the mouth. A compression of the spring applies a force to the labial commissures via the conformers.
