从“盲操”到精准力触感知！中国团队光纤力感知技术突破，让手术机器人“手感”媲美外科医生！

Core Viewpoint - The article emphasizes the importance of in-situ force sensing and feedback technology in minimally invasive surgical robots, highlighting its critical role in enhancing surgical safety, precision, and efficiency [1][3]. Group 1: Technological Advancements - The Da Vinci 5th generation laparoscopic surgical robot, integrating a force feedback system in 2024, reduced peak interaction forces in the surgical area by 43%, significantly improving safety thresholds [1]. - The research team developed a novel Bragg grating (FBG) sensor technology that addresses existing challenges in multi-dimensional force measurement, achieving a 50% reduction in force-temperature coupling errors compared to traditional sensors [3][8]. - The FBG sensor can withstand 180°C sterilization and is designed for repeated use, reducing costs by over 80% compared to traditional adhesive packaging methods [4][11]. Group 2: Clinical Applications and Testing - The research team successfully integrated the FBG sensor into spinal endoscopic and orthopedic surgical robots, demonstrating its effectiveness through rigorous testing on pig spine models and human cadaver skulls [6][17]. - In laparoscopic simulations, the force feedback system maintained average tissue lifting forces below 3N, compared to 5.6N without feedback, indicating a significant improvement in safety [20]. - In live animal experiments, the FBG sensor effectively monitored interaction forces, ensuring that maximum operational forces remained below 2N, showcasing its advantages in minimally invasive procedures [22]. Group 3: Research Publications - Two significant research papers were published, detailing the advancements in FBG technology for surgical robots, with Zhao Chen as the first author and Professor Li Tianliang as the corresponding author [7].
