Abstract

Introduction: A training system for ultrasound-guided thoracic interventions was developed. The system was designed for a core needle biopsy (CNB) procedure in combination to a custom, pseudo-anthropomorphic lung phantom. Methods: A dedicated phantom was fabricated (Arteaga-Marrero et al. Gels 2023;9:74) to accurately replicate the healthy lung parenchyma as well as pathologies, like abscesses and neoplasms, as solid inclusions. 3D printed ribs were included to provide realism and a higher level of difficulty. The ultrasound (US) training system employed an optical tracking system (OptiTrack V120), a portable US device (Telemed MicrUs EXT-1H L12 Probe),a biopsy needle (Bard 22mm), and other tools required for calibration. The fixtures to allocate the optical trackers were 3D printed. In addition to the 3D models of the system’s components, a virtual and reconstructed model of each phantom was generated. The integration of the system was carried out using Plus Toolkit and the image computing platform 3D Slicer. The training system was complemented with a custom extension implemented in Python. Results: The capabilities of the system were tested by an experienced pulmonologist and medical students training in US-guided interventions. In-plane and out-of-plane needle insertions were performed simulating CNB procedures which are often employed in a clinical setting. Subsequently, the system provided a quantitative report that indicated the level of success of the procedure carried out. Conclusion: Technical considerations and acquired expertise are required to ensure patient safety. Thus, the presented system is dedicated to aid clinical practitioners to be trained in US-guided interventional thoracic procedures.
超声引导胸椎介入治疗的美国培训系统
前言:建立了超声引导胸腔镜介入治疗培训系统。该系统设计用于核心针活检(CNB)程序,并结合定制的伪拟人化肺假体。方法:制作专用假体(Arteaga-Marrero等)。凝胶2023;9:74)准确地复制健康的肺实质以及病理,如脓肿和肿瘤,作为实体包裹体。3D打印肋骨包括提供现实主义和更高的难度。超声(美国)培训系统采用光学跟踪系统(OptiTrack V120)、便携式美国设备(Telemed MicrUs EXT-1H L12探头)、活检针(Bard 22mm)和其他校准所需的工具。分配光学跟踪器的夹具是3D打印的。除了系统部件的3D模型外,还生成了每个幻影的虚拟和重建模型。利用Plus Toolkit和图像计算平台3D Slicer对系统进行集成。培训系统由一个用Python实现的自定义扩展补充。结果:该系统的功能由一位经验丰富的肺科医生和接受过美国指导干预训练的医学生进行了测试。在平面内和平面外的针头插入进行模拟CNB程序,通常用于临床设置。随后,该系统提供了一份数量报告,表明所执行程序的成功程度。结论:需要技术考虑和获得的专业知识来确保患者的安全。因此,本系统致力于帮助临床医生在美国指导下进行胸椎介入手术的培训。
