West China Hospital Develops MicroSpine: A 2mm Robotic Arm System for Minimally Invasive Spinal Surgery
Researchers at West China Hospital of Sichuan University have developed MicroSpine, an ultra-minimally invasive robotic arm system designed for spinal surgery, marking a significant leap forward in surgical robotics. The breakthrough was published in Science Robotics, demonstrating a novel approach to accessing and operating within the confined anatomy of the spinal column. The MicroSpine system features three independently controllable robotic arms, each measuring just 2mm i
Researchers at Sichuan University's West China Hospital have introduced MicroSpine, a compact robotic system designed to revolutionize spinal surgery. The device utilizes three 2mm robotic arms housed within an 8mm sheath, allowing surgeons to navigate complex anatomical structures with high precision. By employing a unique concentric push-pull mechanism, the system can bend up to 120 degrees to reach targets that were previously difficult to access. The platform integrates essential tools, including an endoscope, grasping forceps, and a thulium laser for simultaneous cutting and blood clotting. During initial testing, the robot successfully performed spinal decompression procedures through a small 3cm incision in just 15 minutes. This innovation promises to minimize surgical trauma, decrease recovery times, and improve overall patient outcomes in spinal care.
This technology represents a major advancement in surgical robotics by enabling complex spinal procedures through significantly smaller incisions, potentially reducing patient trauma and hospital recovery times.
