  • Patent number: 11109914
    Abstract: A bone fracture fixation system including reference pins inserted into bone fragments of a patient in a first configuration and an image capture device configured to capture an image of the reference pins, and the bone fragments. The system includes a processor configured to receive and pre-process the captured image data. The processor pre-processes the image data by virtually re-positioning the reference pins in the first configuration into a second configuration, wherein the re-positioning virtually re-positions the bone fragments into normal alignment; and virtually generating a support device. The system includes a point-of-care production apparatus that produces a three-dimensional model of the virtually generated support device in a form that can be applied to the patient.

A suture passes through the flexible fixation member at various points along a length of the body such that portions of the fixation member are slidable relative to the suture and configurable to form a cluster within a surgical site. The delivery device includes a tubular member, an elongated inserter, and a trigger. The elongated inserter is slidably disposed within the tubular member. The inserter has a forked distal end configured to receive a portion of the flexible fixation member and the suture. The trigger is finger-engagable and fixedly coupled to the proximal end of the inserter. It is configured to advance and retract the inserter relative to the tubular member. The trigger includes a retention member for retaining a proximal end portion of the suture.

  • Patent number: 10470809
    Abstract: A tray includes a plurality of rows, each of which includes a plurality of slots. Each row contains a plurality of screws. Different rows may contain screws of different types, e.g., lengths. Each of one or more rows contains a machine-readable object (e.g., peg) containing data representing properties of the objects in the corresponding rows. Removal of an object from a row is performed by reading data from the machine-readable object in the row and using that data to modify (e.g., decrement or increment) a count of the type of object contained in that row.

  • Patent number: 10441435
    Abstract: A method and system for determining the orientation of a surgical tool with respect to a bone of a patient are disclosed. The method includes defining a bone reference plane using a processor; receiving first information at the processor from a first active sensor attached to the bone at a location having a predetermined relationship with the plane, the first information relating to a movement of the first sensor and wherein changes in orientation to the plane are trackable through changes in orientation of the first sensor; receiving second information from a second active sensor attached to the surgical tool, the second information relating to a movement of the second sensor; and determining a three-dimensional orientation of the surgical tool with respect to the plane based on the first and second information. The reference plane may be defined from distances between at least three predetermined reference locations on the bone.
