Patent number: 12290270Abstract: Aspects of present disclosures involve systems, methods, and apparatus for a bone mounted robotic-assisted orthopedic surgery system for precise implant position, soft tissue balancing, and guidance of tools during a surgical procedure, particularly partial or total knee replacement procedure. The system features a bone-mounted robotic arm with an end-effector for precise positioning of a surgical tool, positioning of implants, and balancing of soft tissues. The reconfigurable robotic system requires minimal training by surgeons, is intuitive to use similar to conventional instrumented surgery, and has a small footprint. The system works with existing, conventional instruments, patient-specific instruments, sensor-assisted systems, and computer-assisted systems and does not require increased surgical time and safely provides the enhanced precision achievable by robotic-assisted systems and computer-assisted technologies.Type: GrantFiled: December 20, 2023Date of Patent: May 6, 2025Assignee: Unik Orthopedics, Inc.Inventor: Charlie Wen-Ren Chi

Publication number: 20250041078Abstract: The present invention relates to a system and method for load and gap balancing in knee replacement surgery. The system incorporates sensor devices, such as load cells, pressure, ultrasound or optical, to accurately measure gaps and ligament tensions within the knee joint during surgery. Additionally, a tensioner device, which can be a manual spreader, a spring-loaded mechanism, or a motorized linear actuator, is employed to tension the medial and lateral collateral ligaments, as well as patella tendon, based on the measured data. These real-time measurements are transmitted to a computer or robotic surgery system, which provides real-time visualization of the data and assists the surgeon in determining the appropriate gap and ligament tension for each individual patient. Using soft tissue analysis, the real-time sensor data can be displayed on a computer recommending appropriate gap and ligament tension, implant size and shape, and individualized knee alignment based on optimal outcome.Type: ApplicationFiled: July 30, 2024Publication date: February 6, 2025Inventor: Charlie Wen-Ren CHI
