Abstract

Three-dimensional (3D) localization of magneto-surgical devices is essential for safe and efficient navigation. However, existing magnetic localization methods either limit device miniaturization due to internal sensors or require additional excitation fields and external sensor arrays. Herein, we formulate a localization method based on the special properties of rotating magnetic dipoles, which allow reconstruction of position and rotation axis from a single external tri-axial magnetometer. The rotating dipole is realized through a permanent magnet synchronous motor (PMSM) that can reversibly (un)lock using the heat-induced phase transition of a low melting point alloy. Sequential localization and manipulation is performed by an external mobile electromagnet equipped with a single eye-in-hand Hall effect sensor. We describe the PMSM's thermal and magnetic properties, formulate the governing localization equations, quantify and validate 3D tracking of PMSM pose trajectory, and demonstrate sequential localization and manipulation in a benchtop experiment.

锁定同步电机的磁定位与操作。

磁外科设备的三维定位对于安全、高效的导航至关重要。然而，现有的磁定位方法要么由于内部传感器限制了设备的小型化，要么需要额外的激励场和外部传感器阵列。本文提出了一种基于旋转磁偶极子的特殊性质的定位方法，该方法可以从单个外三轴磁强计中重建位置和旋转轴。旋转偶极子是通过永磁同步电机（PMSM）实现的，该电机可以利用低熔点合金的热致相变可逆锁定。顺序定位和操作是由一个外部移动电磁铁配备一个单一的眼在手霍尔效应传感器。我们描述了永磁同步电机的热学和磁性，制定了控制定位方程，量化和验证了永磁同步电机位姿轨迹的三维跟踪，并在台式实验中演示了顺序定位和操作。
