Orthopedic Cutting Instrument Patents (Class 606/79)
  • Patent number: 11534180
    Abstract: This invention is directed to devices and methods for surgical access to the body, and particularly to surgical drills for accessing a body cavity and methods therefor. In general, a surgical drill is utilized to gain access to a body cavity or part, such as where bone and/or other hard tissues need to be pierced. For example, the skull and other bones with internal cavities may require surgical access to treat body portions contained within the bone. Further in general, it may be generally desirable to create access holes or openings which may be as small as possible and at a particular direction and/or trajectory. In this manner the access hole or opening may be utilized to guide another device, such as a treatment device, to a particular target along the established trajectory of the access hole or opening.

  • Patent number: 10945744
    Abstract: Drill guides and related methods are disclosed herein, e.g., for use in surgical procedures. In some embodiments, a drill guide can include an adjustment mechanism that permits one-handed adjustment of the guide depth and does not require that the drill guide be removed from the patient or that the drill be removed from the drill guide when making an adjustment. The adjustment mechanism can include a trigger that moves first and second detents into and out of engagement with a guide stem to allow step-wise adjustment of the guide depth.

  • Patent number: 10888340
    Abstract: A wedge osteotomy method inserts a first wire into a first bone of the foot, distal from tissue to be removed. A second wire is inserted into a second bone, so the tissue to be removed is distal from the second wire. A cut guide is pivoted about the first wire, until a first axis of the cut guide is parallel with a longitudinal axis of the first metatarsal. The cut guide has a slot perpendicular to the first axis for guiding a cutter to cut bone, while the first axis is aligned with the longitudinal axis of the first metatarsal. The cut guide is then pivoted about the second wire, until the first axis is aligned with the longitudinal axis of the talus, and bone is cut through the slot, to form a second planar cut into or through bone material.

  • Patent number: 10849631
    Abstract: Instruments and surgical techniques may be used to correct a bone deformity, such as a bunion in which a metatarsal is misaligned with respect to a medial cuneiform. In some examples, a bone cutting guide is utilized to cut an end of the metatarsal and/or an end of the medial cuneiform to facilitate realignment of the bones. The cutting guide can have a pivotable cut guide surface along which a cutting instrument is translated to provide a precise bone cut. In some applications, after suitably preparing and aligning the bones, the bones are compressed together using a fixation pin. The fixation pin can be driven through one of the bones, into the second bone, and then further driven to compress the bones together.
