顶刊重磅!失明患者新希望!机器人自主视网膜静脉插管系统来了
机器人大讲堂· 2025-12-30 14:00
视网膜静脉阻塞( RVO)作为 全球第二大致盲性视网膜血管疾病 , 给全球数千万患者带来困扰 。想象一 下,要在 平均 直径仅 151微米 的血管上做手术 ——这比头发丝还细,而医生的手部震颤幅度却 可 达 182 微米。 传统治疗方法如 抗血管内皮生长因子治疗 只能缓解症状,无法根除病因,患者需要反复治疗,费用高昂且有 感染风险。而 视网膜静脉插管 ( RVC) 手术 虽然能直接清除血栓,但因为操作难度太大,很少有医生能够 掌握。 近日 ,约翰斯 ·霍普金斯大学的研究团队在 国际顶刊 《 Science Robotics》 上发表了一项突破性成果。 他们开发出 基于深度学习的自主视网膜静脉插管系统 ,在离体猪眼实验中实现了 90%的成功率 。即便模拟 呼吸导致的眼部运动,成功率仍高达 83% 。 ▍ 失明患者 新希望,在比发丝更细的血管上 操作手术 这套系统的核心亮点在于 机器人即可自主完成导航、接触、穿刺等一系列超越人类生理极限的微米级操作 , 为 RVO治疗开辟了精准、高效的新路径。 在固定猪眼实验中,系统将 针体导航时间从 57.45秒缩短至30.56秒 , 穿刺及回撤时间从 43.55秒压缩至 9. ...
