  • 切割成功率提升3倍,峰值切割力降低至一半。
  • 适合需要高精度与安全性的自动化手术系统研究者。

电外科通过降低切割力和出血量来改善组织切割效果,但会增加周围组织热损伤风险。经验丰富的外科医生依靠经验判断理想切割速度,却缺乏量化参考。以往自主电外科多采用恒定工具速度,对组织特性、功率设置或工具类型变化不鲁棒。热成像反馈可提供信息,用于在控制工具速度的同时减少热损伤并平衡切割力。本文提出热成像驱动的电外科速率调制优化方法(ThERMO),通过智能调节工具速度实现自主减少热损伤并平衡切割力。在组织模拟物上验证了ThERMO性能,并与恒定速度方法对比。结果表明,ThERMO将切割成功率提升3倍,峰值切割力降低2倍。该方法能响应环境扰动,减少组织损伤,完成恒定速度方法会导致灾难性失败的任务。

原文摘要 · Abstract (English)

Electrosurgery is a surgical technique that can improve tissue cutting by reducing cutting force and bleeding. However, electrosurgery adds a risk of thermal injury to surrounding tissue. Expert surgeons estimate desirable cutting velocities based on experience but have no quantifiable reference to indicate if a particular velocity is optimal. Furthermore, prior demonstrations of autonomous electrosurgery have primarily used constant tool velocity, which is not robust to changes in electrosurgical tissue characteristics, power settings, or tool type. Thermal imaging feedback provides information that can be used to reduce thermal injury while balancing cutting force by controlling tool velocity. We introduce Thermography for Electrosurgical Rate Modulation via Optimization (ThERMO) to autonomously reduce thermal injury while balancing cutting force by intelligently controlling tool velocity. We demonstrate ThERMO in tissue phantoms and compare its performance to the constant velocity approach. Overall, ThERMO improves cut success rate by a factor of three and can reduce peak cutting force by a factor of two. ThERMO responds to varying environmental disturbances, reduces damage to tissue, and completes cutting tasks that would otherwise result in catastrophic failure for the constant velocity approach.
