  • Patent number: 11154359
    Abstract: A method of cutting a bone (2) comprises the steps of: preparing the bone (2) in order to be accessible to an osteotomic instrument; predefining an osteotomic geometry on the bone (2); and applying the osteotomic instrument to the bone (2) thereby cutting the bone (2) along the osteotomic geometry and generating a cut surface (21) to the bone (2). The method further comprises delivering a laser beam to the cut surface (21) of the bone (2) such that the cut surface (21) of the bone (2) is ablated. The method according to the invention allows to improve healing of a bone at its cut surface after being cut by the osteotomic instrument.

  • Patent number: 11147684
    Abstract: A cage device for harvesting bone graft material for use in bone fusion surgery, e.g., a spinal fusion. The device has a chamber configured to contain a slurry of morselized bone and blood that effuses from adjacent bones when the device is placed in a space between the bones, and a bone cutter assembly is inserted into the chamber and operated. In one embodiment, the cutter assembly includes an elongated cannula having a bend at a distal end, and a wire arranged to slide inside the cannula so that a cutting tip of the wire can be set to project a desired distance from the distal end. When the cannula is driven to rotate about its long axis, the wire cutting tip strikes and cuts grooves in the facing surfaces of the bones to produce the mentioned slurry which remains inside the chamber to promote a solid and healthy fusion.

  • Patent number: 10603177
    Abstract: Systems and methods for joint preparation and fusion are disclosed. The system includes a cutting device having a handle, and rigid blade member. The blade member may include cutting edges on first and second sides, and may be curved in one or more planes. The blade member may be deployed to project outside of an outer tube, and the cutting device may be rotated to create a circular cavity. In a method of use, a cannula provides access to a procedure site such as a joint. A pathway to the joint is created, and the cutting device is inserted and deployed to undercut a cavity in the joint. A fusion device may be implanted across the joint to provide compression and fuse the joint. The system may also include instrumentation for creating access to a joint, bone graft insertion and implant insertion.

  • Patent number: 10575781
    Abstract: Within examples, a surgical device with an embedded sensor system for performing hip replacements is described. This device mitigates fracturing of the mid metaphyseal/diaphyseal region of the femur, and ensures adequate press-fit of the component into the bone. The device relays information regarding forces experienced by the patient's bone to a separate data acquisition device and displays it on an interface. This information is used by the surgeon to determine the force present inside of the patient's bone during broaching, and can then be used to provide better care, and mitigate fractures due to overloading in the bone.

  • Patent number: 10568644
    Abstract: An orthopaedic surgical instrument assembly includes a system handle configured to clamp a broach and femoral stem trial assembly. The system handle includes a clamp lever and a release lever both pivotally coupled to the system handle, and a leaf spring connecting the clamp lever and the release lever. When the release lever is moved from an unclamped position to a clamped position, the leaf spring is put in tension, and the clamp lever engages a flange of the broach, securing the broach to the system handle. Methods of assembling the system handle are described and claimed.

  • Patent number: 10456262
    Abstract: An implant includes a base, a flange, and ridge. The flange extends from the base. The ridge extends from the flange. A hole extends through the flange and the ridge. A system with the implant includes a fastener extending through the ridge of the implant. The implant is placed into bone by securing a base of the implant to a main complementary contact surface of bone and by securing a ridge extending outwardly from a flange of the implant to a secondary complementary contact surface of bone spaced from the main complementary contact surface.

  • Patent number: 10441365
    Abstract: Methods and devices to track patient anatomy during a surgical operation. A patient reference device is attached to an anatomical feature of a patient and it includes an attachment base and an optically-trackable array detectable by an optical navigation system and having a longitudinally-extending arm to space apart the fixed geometric pattern from the anatomical feature. The arm includes a connector to be detachably secured to the attachment base. An inertial measurement unit within the attachment base enables determining, based on comparing a threshold level to a motion signal, that the attachment base has changed position, wherein the motion signal represents the change in position and its magnitude. Based on determining that the attachment base has changed position an alarm signal is generated an and an output device in the attachment base outputs an alarm in response to the alarm signal.
