  • Publication number: 20250169807
    Abstract: A joint balancing insert with sensors and an actuated mechanism is disclosed. The joint balancing insert is used to balance a joint during arthroplasty surgery, as the sensors provide force, position and angular data relating to the movement of the joint, while the actuated mechanism allows for highly accurate and dynamic adjustments of the joint based on the data from the sensors. Various configurations of actuated mechanisms and sensors may be implemented in the insert to provide for manual or real time control of the insert, and customized interfaces are provided for visualized feedback of adjustments. Sensor data may also be collected and compared with expected or preferred data sets to provide adjustment recommendations and achieve better outcomes based on historical data.

  • Publication number: 20250120784
    Abstract: A joint replacement balancing system which provides real-time feedback to a surgeon during a joint replacement surgery to assist the surgeon to balance a joint replacement. The joint replacement balancing system includes a non-transitory processor-readable medium storing code representing instructions to cause a processor to receive a signal from a joint balancing apparatus, determine if the joint replacement is out of balance, determine a corrective course of action to bring the joint into balance and generate and display to the surgeon during the joint replacement surgery a recommended corrective course of action to complete the joint replacement surgery.

  • Patent number: 12245740
    Abstract: Methods of bioprinting a bio-ink construct on an internal tissue defect or a chondral defect during a minimally invasive surgery on an individual in need thereof are provided, comprising: visualizing the defect; positioning a bioprinter comprising a printhead within proximity of or in contact with the defect; and ejecting a bio-ink from the printhead onto the defect to form a bio-ink layer, thereby generating a bio-ink construct. Further provided are systems for bioprinting a bio-ink construct on an internal tissue defect during a minimally invasive surgery on an individual in need thereof, comprising a control system, an endoscope, and a bioprinter comprising a printhead.
