  • Lattice impaction pad
    Patent number: 11534257
    Abstract: In some embodiments, the present disclosure relates to a method of securing an implant into a body of a patient. Initially, the implant is placed into the body of the patient. Then, an impactor tool is used to apply a force to the implant. Subsequent to the application of force to the implant, a portion of an impaction pad on an end of the impactor tool is monitored. When the portion is observed to be deformed, the application of force onto the implant is discontinued.

  • Device for in-situ fabrication process monitoring and feedback control of an electron beam additive manufacturing process
    Patent number: 11532760
    Abstract: A High Energy Beam Processing (HEBP) system provides feedback signal monitoring and feedback control for the improvement of process repeatability and three-dimensional (3D) printed part quality. Signals reflecting process parameters and the quality of the fabricated parts are analyzed by monitoring feedback signals from artifact sources with a process controller which adjusts process parameters. In this manner, fabricated parts are produced more accurately and consistently from powder feedstock by compensating for process variation in response to feedback signals.

  • Implant Selection And Surgical Planning Based On Patient Specific Kinematics
    Publication number: 20220387187
    Abstract: In one embodiment, a method of planning implantation of a knee prosthesis is performed. Data is collected that is representative of a position of a tibia relative to a femur at a plurality of positions of the tibia relative to the femur through a range of motion of the knee. The data at each position of the plurality of positions includes: a medial maximum convergence of a low point on a medial femoral condyle and a medial tibial articular surface of the tibia and a lateral maximum convergence of a low point on a lateral femoral condyle and a lateral tibial articular surface of the tibia. The medial and lateral convergence locations from the plurality of positions are analyzed to determine a kinematic pattern that is then used to determine an implant position and an implant orientation for a tibial implant to be placed on a resected tibial surface.

  • ROBOTIC SYSTEM FOR SHOULDER ARTHROPLASTY USING STEMLESS IMPLANT COMPONENTS
    Publication number: 20220354668
    Abstract: Robotic system and methods for preparing a bone of a joint to receive an implant. Virtual object(s) are used to define a volume of material to be removed from the bone for receipt of the implant. A robotic manipulator controls a cutting tool based on the virtual object(s) to form a first cavity and a second cavity in the bone. The second cavity is formed beneath the first cavity and is rotated relative to the first cavity to define an undercut in the bone. The first and second cavities receive a body and a locking member of the implant in an unlocked position. The locking member is rotated within the second cavity to a locked position whereby the undercut engages the locking member to limit withdrawal of the implant from the bone.

  • Virtual ligament balancing
    Patent number: 11484251
    Abstract: A method of generating a correction plan for a knee of a patient includes obtaining a ratio of reference bone density to reference ligament tension in a reference population. A bone of the knee of the patient may be imaged. From the image of the bone, a first dataset may be determined including at least one site of ligament attachment and existing dwell points of a medial femoral condyle and lateral femoral condyle of the patient on a tibia of the patient. Desired positions of contact in three dimensions of the femoral condyles of the patient with the tibia of the patient may be obtained by determining a relationship in which a ratio of bone density to ligament tension of the patient is substantially equal to the ratio of reference bone density to reference ligament tension.

  • Anterior cervical plate
    Patent number: 11478283
    Abstract: An anterior cervical plate system is provided. The cervical plate includes a retention ring with a deflectable flange that is upwardly spaced from the top surface of the ring and configured to prevent an inserted bone fastener from backing out of the plate. The plate includes a locking pin having a camming surface and a blocking surface. When the camming surface is moved into position adjacent to the flange, the flange is free to flex out of the way of a bone screw being inserted into or removed from the plate. When the blocking surface is positioned adjacent to the flange, outward deflection of the flange is prevented to retain the bone screw inside the plate. The locking pin is rotated through a camming surface to bring a blocking surface against the flange deflecting the flange onto the head of the bone screw.
