  • Patent number: 11974762
    Abstract: Jigs for guiding femur and tibia resectioning in knee surgery contain bone-jig contact surfaces and a cutting guide as a single unitary piece. Contact surfaces are curvilinear surfaces formed into ends of projections from a jig base. Each jig has three pairs of contact surfaces selected to abut low-wear, lateral and medial, articular surface features, such that only one self-locking position against the bone (or cartilage) is possible and the integral cutting guide will define only one cut plane for the resectioning. An improved rotational transformation that converts scan views into desired proper axes is based on projections of rotated coordinates onto the plane of rotation to produce parameters that closely correspond to the joint surfaces in the desired jig coordinates.

  • Patent number: 11957364
    Abstract: Provided is a guide assembly for guiding a bone cutting tool through a small incision in the skin near the bone that allows movement of the cutting tool in the bone in a wide angle while the cutting tool is rotated about a pivot point that is located at the small incision. The guide assembly includes a 2-piece construction that includes a guide component that holds the cutting tool and a track component having a semicircular arc shape on which the guide component is slidably engaged whereby sliding the guide component along the track component guides the movement of the cutting tool to rotate about a pivot point that is the center of curvature of the semicircular arc shape of the track component.

  • Patent number: 11929040
    Abstract: A user interface display may have a display and may have a backlight that lights the display. The display may implement pixels to generate colors and images. The display may be backlit. The backlight may use pixels having emitters to generate different color backlighting. In various instances, the display or the backlight or both may include a deep blue emitter. The blue emitter may be used in combination with red and green pixels elements to generate different colors. By implementing deep blue emitters rather than conventional blue (e.g., cyan) emitters, the effects of cyan light on a viewer's circadian rhythm may be limited or eliminated. Moreover, by implementing deep blue emitters, the effects of cyan light on a viewer's circadian rhythm may be varied, while the colors and images are reproduced for viewing without introducing significant color distortion.

  • Patent number: 11918491
    Abstract: A force and rotation sensing device can be suitable for measuring a force within a knee joint. A force sensor can measure a force exerted between opposing surfaces of a housing. A force display positioned on the housing can visually represent a value of the measured force, such as with a dual-sided light-emitting diode display that is visible from opposing sides of the housing. A first rotation sensor can measure a flexion/extension position of the housing. A flexion/extension display can visually represent a value of the measured flexion/extension position. In some examples, a zero button can set a reference orientation of the housing, so that the first rotation sensor can measure the flexion/extension position as a relative rotation with respect to the reference orientation. In some examples, circuitry can wirelessly transmit data corresponding to the value of the measured flexion/extension position.

  • Patent number: 11918490
    Abstract: A workstation having a pair of posts on either side of a clamping plate where a donor bone may be placed on sequentially cut in three separate cutting paths. Cutting gates are attached to the posts and used to provide cutting paths that can be precisely oriented with respect to the meniscus of the donor bone part using visual alignment without any manual measurements. The graft is affixed to a machining clamp and shaved to appropriately shape the sides and form a radius on the bottom of the graft. A tibia is then prepared by using a drill guide to form a pilot hole and then to drill out a large hole for the graft. The drilled hole is expanded and shaped using a rod guide and chisel and then a rasp. The shaped graft may then be implanted into the shaped hole and sutured in place.
