LapSurgie: Humanoid Robots Performing Surgery via Teleoperated Handheld Laparoscopy
- 通过逆映射策略实现手持腹腔镜器械的精准控制
- 无需额外设备即可在普通手术室使用现成器械
- 适合医疗资源匮乏地区推广,降低手术机器人使用门槛
近年来,机器人腹腔镜手术因其有望实现更高效、更精确的微创手术而受到广泛关注。然而,手术机器人平台的应用仍主要局限于高资源医疗中心,加剧了城乡及低资源地区之间的医疗不平等。为缩小这一差距,已有远程指导和完全远程手术等方案被探索,但将手术机器人系统实际部署到欠发达社区仍是未解难题。类人机器人提供了一条可行路径,因其可直接在为人类设计的环境中运行,无需对手术室等基础设施进行大规模改造。本文提出LapSurgie,首个基于类人机器人的腹腔镜远程操作框架。该系统采用逆映射策略,适配带有人工腕部的腹腔镜器械,并满足远程运动中心约束,实现对市售手术器械的精确手控,且无需额外设置。控制台配备立体视觉系统,提供实时视觉反馈。跨平台用户研究证明了该框架的有效性,并初步验证了类人机器人在腹腔镜手术中应用的可行性。
原文摘要 · Abstract (English)
Robotic laparoscopic surgery has gained increasing attention in recent years for its potential to deliver more efficient and precise minimally invasive procedures. However, adoption of surgical robotic platforms remains largely confined to high-resource medical centers, exacerbating healthcare disparities in rural and low-resource regions. To close this gap, a range of solutions has been explored, from remote mentorship to fully remote telesurgery. Yet, the practical deployment of surgical robotic systems to underserved communities remains an unsolved challenge. Humanoid systems offer a promising path toward deployability, as they can directly operate in environments designed for humans without extensive infrastructure modifications -- including operating rooms. In this work, we introduce LapSurgie, the first humanoid-robot-based laparoscopic teleoperation framework. The system leverages an inverse-mapping strategy for manual-wristed laparoscopic instruments that abides to remote center-of-motion constraints, enabling precise hand-to-tool control of off-the-shelf surgical laparoscopic tools without additional setup requirements. A control console equipped with a stereo vision system provides real-time visual feedback. Finally, a comprehensive user study across platforms demonstrates the effectiveness of the proposed framework and provides initial evidence for the feasibility of deploying humanoid robots in laparoscopic procedures.
