Knee Or Knee Joint Patents (Class 606/88)
  • 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.

    Abstract: The disclosed technology relates to robotic surgical systems for improving surgical procedures. In certain embodiments, the disclosed technology relates to robotic surgical systems for use in osteotomy procedures in which bone is cut to shorten, lengthen, or change alignment of a bone structure. The osteotome, an instrument for removing parts of the vertebra, is guided by the surgical instrument guide which is held by the robot. In certain embodiments, the robot moves only in the “locked” plane (one of the two which create the wedge—i.e., the portion of the bone resected during the osteotomy). In certain embodiments, the robot shall prevent the osteotome (or other surgical instrument) from getting too deep/beyond the tip of the wedge. In certain embodiments, the robotic surgical system is integrated with neuromonitoring to prevent damage to the nervous system.

  • Patent number: 11642138
    Abstract: Disclosed herein is a patella clamp configured to grip a patient's patella. The patella clamp includes a clamping assembly, a ratchet arm assembly, and a handle assembly. The clamping assembly includes first and second patella grip portions mounted in opposing relationship. In use, actuation of the handle assembly moves the second patella grip portion towards the first patella grip portion to clamp the patient's patella. The handle assembly is configured to be moveably adjustable (e.g., rotatable) relative to the clamping assembly. For example, each of the first and second patella grip portions are coupled to mating features mounted on the ratchet arm assembly. Decoupling of the mating features allows the first and second patella grip portions to rotate about the longitudinal axis of the ratchet arm assembly. Thus arranged, the patella clamp is configured to enable the surgeon to reposition the handle assembly to provide increased visibility, etc.
