  • Patent number: 11864838
    Abstract: A system and device (110) for determining bone laxity. For example, the system includes a tracked probe (300) comprising at least one probe marker (310) and a computer assisted surgical (CAS) system (100). The CAS system includes a navigation system (130) and a processing device (110) operably connected to the navigation system and a computer readable medium configured to store one or more instructions that, when executed, cause the processing device to receive location information from the navigation system, generate (820) a surgical plan comprising a post-operative laxity assumption (720), collect (850) first motion information related to movement of the joint through a first range of motion, collect (860) second motion information related to movement of the joint through a second range of motion, determine (870) a post-operative laxity (710), and compare the post-operative laxity and the post-operative laxity assumption to determine laxity results.

  • Publication number: 20240000514
    Abstract: The present disclosure provides a machine learning model to model a normal version of a bone from an abnormal version of the bone. The machine learning model can be trained with a training set including abnormal bone images and corresponding normalized, or post-operative, bone images. The abnormal bone image and the inferred normal bone image can be used to plan a surgery to correct the abnormal bone with a surgical navigation system.

  • Publication number: 20240000513
    Abstract: Systems for fusing arthroscopic video data are described. A system comprises an arthroscopic assembly, an inertial measurement unit (IMU) mounted on the arthroscopic assembly, a processor, and a processor-readable storage medium. An arthroscopic surgical plan, images from the arthroscopic assembly, and measurements from the IMU may be obtained. The images and the measurements may be combined to form a data combination. The data combination may be filtered to form a fused data set. The fused data set may control a device. A map of an arthroscopic surgical site may be created based on the fused data set, and a position of the arthroscopic assembly with respect to the arthroscopic surgical site may be calculated. The arthroscopic surgical plan may be updated based on at least one of the map of the arthroscopic surgical site and the position of the arthroscopic assembly.

  • Patent number: 11850348
    Abstract: A negative pressure wound therapy apparatus can include a wound dressing, a fluid collection container, a vacuum pump comprising a pump motor, and tubing. Additionally, the apparatus can include a pressure sensor that measures a pressure in the tubing. One or more tubes can channel a fluid between the wound dressing, the fluid collection canister, and the pump. In addition, first and second control circuits can be provided for controlling the pump motor without using a processor. The first control circuit can generate a difference signal between a desired pressure input and a pressure sensor input, and can further generate a motor control signal responsive to the difference signal. Moreover, a second control circuit can provide an override signal based at least in part on the difference signal and at least one reference signal. The override signal beneficially overrides the motor control signal to prevent the pump motor from stalling.

  • Publication number: 20230404566
    Abstract: Methods of joint repair employing sutures and attached fixation devices are discussed. For example, a bone block graft procedure (e.g., Latarjet) is discussed which employs fixation devices to secure contact between graft surfaces of two bones. A suture construct, including a continuous suture loop routed through a first fastener, is secured to a first bone. Looped ends of the suture loop are passed through passageways formed in the two bones. The looped suture ends are further routed through a second fastener. The second fastener is mounted to the second bone and a sliding knot, formed in the looped suture ends, is advanced into contact with the second fastener. The suture is further tensioned using a tensioner device to secure the two bones together.

  • Patent number: 11832893
    Abstract: A method of establishing access to a hip joint is disclosed. Pre-operative images of the hip joint are processed to produce a first three-dimensional model (pelvis) and a second three-dimensional model (femur). Data from the first probe and data from the second probe are collected and processed to produce a third three-dimensional model (pelvis) and a fourth three-dimensional model (femur), respectively. The first and third three-dimensional models are aligned to produce a first aligned model (pelvis), and the second and fourth three-dimensional models are aligned to produce a second aligned model (femur). A target location is determined between the first and second aligned models, and an entry vector cone is determined from the target location. A navigated guide wire is inserted along the entry vector cone to the target location.

  • Publication number: 20230371964
    Abstract: A system for preparing a bone for implantation of a component of an orthopedic implant device. The system includes a forming tool having a sleeve member that is selectively received within a handle member. The sleeve member has a guide slot that is sized to receive axial passage of at least a portion of a guide. The guide slot and/or sleeve member may be positioned and/or configured to facilitate at least linear and/or rotational displacement of the forming tool about, or relative to, the guide, and thereby provide a degree of freedom in the location at which the forming tool may form a shape or opening in the bone relative to one or more reference axes. The handle member may include a connection member that is structured to be operably coupled to a bone preparation device that is structured to facilitate the displacement of bone material.
