Semi-automatic percutaneous reduction of intra-articular joint fractures - An initial analysis

摘要: Robot-assisted orthopaedic surgery has proved to provide better outcomes over conventional in terms of improved spatial accuracy and more reliable repeatable results. We present a novel use robots - precise anatomic reduction joints' fractures. The joints the body are frequently involved bone breaks, typically classified as intra-articular If joint is function properly again, that pain-free stability movement, broken pieces must be subjected an being put back together perfectly possible. Having minimally invasive, closed starting point, our method involves rigorous surgical workflow analysis create general framework for robotic techniques. Small lightweight parallel manipulators utilized this pilot study move fragments through pre-calculated trajectories. In paper, initial clinical functional requirements robot-assisted presented, followed by description developed physical system invasive surgery. Experimental results show simple graphical user interface sufficient obtain transformation parameters position space. fragment manipulating devices can align with ±1mm ±5degress.
