科学领域:

  • 机器人技术 机器人技术 机器人技术
  • 外科教育的外科教育
  • 机器学习 机器学习

背景情况:

  • 评估外科技能对于提高培训和确保患者护理质量至关重要.
  • 机器人辅助手术 (RAS) 需要客观的方法来评估外科医生的专业知识.
  • 视觉指标在复杂的外科手术过程中为技能评估提供了一个有希望的途径.

研究的目的:

  • 开发一个梯度增强分类模型 (GBM) 用于在RAS.中分类外科专业知识.
  • 用视觉指标从眼睛的目光数据来分类技能水平.
  • 评估视觉指标与已建立的外科技能评估工具 (GEARS) 之间的关联.

主要方法:

  • 记录了11名参与者从四个不同的RAS子任务中获得的目光数据.
  • 从目光数据中提取视觉指标,以表示外科手术的性能.
  • 使用梯度提升分类模型 (GBM) 和ANOVA进行技能分类和分析.

主要成果:

  • 通过使用视觉指标,实现了各种外科手术子任务的高分类准确率 (95-96%).
  • 在所有子任务 (p<0.01) 中,在技能水平之间表现有显著差异.
  • 在提取的视觉指标和全球机器人技能评估 (GEARS) 指标之间发现了强烈的关联 (R2 > 0.7).

结论:

  • 在视觉指标上训练的机器学习模型有效地将手术技能水平分类到RAS中.
  • 可视化指标可用于评估全球机器人技能评估 (GEARS) 措施.
  • 单独完成任务的时间不足以进行全面的外科技能评估.
