Today’s Patent – Robotic systems with vibration compensation, and related methods

The said invention (US20240366325A1) was invented by Gerardo Angel Gonzalez ChapaScott Hudson, patented by USPTO on 23-01-2022. Currently, it stands assigned to Monogram Technologies Inc.

Traditional orthopedic surgical robots and powered cutting tools have improved the precision and efficiency of surgical procedures compared to manual methods. However, a critical limitation of these robots is the generation of vibratory forces during the operation of cutting tools, such as oscillating saws or rotary burrs. These vibrations compromise the accuracy of the toolpath, increase the risk of unintended cuts, and can cause wear or acute failure of robotic components. Current systems often require manual intervention for tool movement and lack sufficient mechanisms to mitigate or prevent vibration, reducing their reliability and safety in surgical environments.

The disclosed invention introduces advanced surgical robots and robotic system components designed to prevent and mitigate vibratory forces during surgical cutting operations. By integrating vibration mitigation features, such as optimized tool motion, vibration-dampening mounts, and tuned mass dampers, the system enhances the safety, accuracy, and reliability of cutting procedures. These innovations enable fully autonomous surgical robots to execute pre-planned cuts while maintaining precise control over the toolpath. Additionally, the reduced vibration improves the longevity of robotic components and allows surgeons to focus on other tasks, enhancing efficiency and creating a more open operating room environment.
