医疗设备行业通过集成微芯片和现场可编程门阵列（FPGAs）等复杂电子元件，显著提升了救命设备的安全性和可用性。然而，这些机电系统引入了难以用传统方法检测的复杂故障模式。随着对电子元件依赖度增加，有效的故障检测与缓解变得至关重要。本文研究了三种基于生成式机器学习的故障检测方法，使用手术吻合器（一类2类医疗设备）的传感器数据进行评估。尽管此类设备过去被认为风险较低，但近年来却与越来越多的伤害和死亡事件相关。研究对比了这些机器学习方法的性能与数据需求，突显其在提升设备安全性方面的潜力。
原文摘要 · Abstract (English)
The medical device industry has significantly advanced by integrating sophisticated electronics like microchips and field-programmable gate arrays (FPGAs) to enhance the safety and usability of life-saving devices. These complex electro-mechanical systems, however, introduce challenging failure modes that are not easily detectable with conventional methods. Effective fault detection and mitigation become vital as reliance on such electronics grows. This paper explores three generative machine learning-based approaches for fault detection in medical devices, leveraging sensor data from surgical staplers,a class 2 medical device. Historically considered low-risk, these devices have recently been linked to an increasing number of injuries and fatalities. The study evaluates the performance and data requirements of these machine-learning approaches, highlighting their potential to enhance device safety.
