TumorMap用激光与AI实现肿瘤3D建模与自动切除,精度达亚毫米级。
TumorMap: A Laser-based Surgical Platform for 3D Tumor Mapping and Fully-Automated Tumor Resection
- 融合三种激光与深度学习,实现术中肿瘤边界实时三维建模。
- 在小鼠骨肉瘤和软组织肉瘤模型中实现亚毫米级精准切除。
- 无需人工干预的全自动手术系统,适合微创精准外科研究。
恶性实体肿瘤的手术切除高度依赖医生对病灶组织的准确定位及肿瘤切除同时保留周围健康组织的能力。然而,由于缺乏高保真肿瘤重建技术、难以建立能应对肿瘤诊断固有复杂性的通用组织模型,以及双手操作的自然物理限制、生理性震颤和疲劳累积等因素,术中构建三维肿瘤模型并实施切除面临重大挑战。为此,我们提出“TumorMap”——一种基于多激光功能的手术机器人平台,通过整合光学相干断层扫描、激光诱导内源性荧光与切割激光刀三重机制,并结合深度学习模型,实现完全自动化、非接触式的肿瘤切除。我们在小鼠骨肉瘤和软组织肉瘤模型中验证了TumorMap性能,并建立了一种新型组织病理学流程以评估传感器表现。结果表明,该系统实现了亚毫米级激光切除精度,成功完成多模态传感器引导下的全自动肿瘤手术,全程无需人工介入。
原文摘要 · Abstract (English)
Surgical resection of malignant solid tumors is critically dependent on the surgeon's ability to accurately identify pathological tissue and remove the tumor while preserving surrounding healthy structures. However, building an intraoperative 3D tumor model for subsequent removal faces major challenges due to the lack of high-fidelity tumor reconstruction, difficulties in developing generalized tissue models to handle the inherent complexities of tumor diagnosis, and the natural physical limitations of bimanual operation, physiologic tremor, and fatigue creep during surgery. To overcome these challenges, we introduce "TumorMap", a surgical robotic platform to formulate intraoperative 3D tumor boundaries and achieve autonomous tissue resection using a set of multifunctional lasers. TumorMap integrates a three-laser mechanism (optical coherence tomography, laser-induced endogenous fluorescence, and cutting laser scalpel) combined with deep learning models to achieve fully-automated and noncontact tumor resection. We validated TumorMap in murine osteoscarcoma and soft-tissue sarcoma tumor models, and established a novel histopathological workflow to estimate sensor performance. With submillimeter laser resection accuracy, we demonstrated multimodal sensor-guided autonomous tumor surgery without any human intervention.
