Surgical instrument segmentation in robot-assisted surgery (RAS) - especially that using learning-based models - relies on the assumption that training and testing videos are sampled from the same domain. However, it is impractical and expensive to collect and annotate sufficient data from every new domain. To greatly increase the label efficiency, we explore a new problem, i.e., adaptive instrument segmentation, which is to effectively adapt one source model to new robotic surgical videos from multiple target domains, only given the annotated instruments in the first frame. We propose MDAL, a meta-learning based dynamic online adaptive learning scheme with a two-stage framework to fast adapt the model parameters on the first frame and partial subsequent frames while predicting the results. MDAL learns the general knowledge of instruments and the fast adaptation ability through the video-specific meta-learning paradigm. The added gradient gate excludes the noisy supervision from pseudo masks for dynamic online adaptation on target videos. We demonstrate empirically that MDAL outperforms other state-of-the-art methods on two datasets (including a real-world RAS dataset). The promising performance on ex-vivo scenes also benefits the downstream tasks such as robot-assisted suturing and camera control.

手术器械的自动定位是了解手术过程并对其进行分析从而为外科医生提供有意义的术中指导或术后手术指标的重要技术。我们引入了一个新的数据集,反映了手术器械的运动学特征,用于手术视频的自动手术器械定位。hSDB(hutom Surgery DataBase)-仪器数据集由24例腹腔镜胆囊切除术和24例机器人胃切除术的仪器定位信息组成。所有仪器的定位信息以用于目标检测的限界框的形式提供。为了处理仪器之间的类别不平衡问题,在Unity中为3D模型建模的合成仪器被包括作为训练数据。此外,对于3D仪器数据,提供了多边形注释以实现工具的实例分割。为了反映所有器械的运动学特征,腹腔镜器械用头部和身体部位注释,机器人器械分别用头部、手腕和身体部位注释。辅助工具(标本袋、针头等)标注数据经常用于外科手术的也包括在内。此外,我们提供了统计信息的hSDB仪器数据集和基线定位性能的目标检测网络训练的MMDetection库和分析结果。

传统的治疗方法由于有限的视野而限制了外科医生的灵活性控制。随着机器人辅助手术的出现,微创手术的医疗技术发生了范式转变。然而,在手术场景中跟踪手术器械的位置是非常具有挑战性的,并且手术工具的准确检测和识别是至关重要的。手术视频帧中基于深度学习的语义分割有可能促进这一任务。在这项工作中,我们修改了名为U-NetPlus的U-Net架构,通过引入预训练的编码器并重新设计解码器部分,通过使用基于最近邻(NN)插值的上采样操作替换转置卷积操作。为了进一步提高性能,我们还采用了非常快速和灵活的数据增强技术。我们在8 x 225帧机器人手术视频序列上训练了框架,这些视频可通过MICCAI 2017 EndoVis Challenge数据集获得,并在8 x 75帧和2 x 300帧视频上进行了测试。使用我们的U-NetPlus架构,我们报告了90.20%的DICE用于二进制分割,76.26%的DICE用于仪器部件分割,46.07%用于仪器类型(即,所有仪器)分割,优于在这些数据上实施和测试的先前技术的结果。
