Optical control system of the geometric model constructed in 3D space for magnetic stereotaxis

Abstract

This paper studies the feasibility of reciprocating motion of non-contact control implants (small permanent magnets) by simulating a magnetic stereotaxic system using COMSOL software. The experimental results are consistent with the simulation results. When the large permanent magnet (LPM) on one side is approached, it will attract the small permanent magnet (SPM) to move towards the barrel wall, and when it leaves, the small permanent magnet stays at the barrel wall. At this time, the large permanent magnet on the other side begins to approach. When a certain distance is reached, the small permanent magnet is attracted by it, moves from one side of the barrel wall to the other side, and stays on the barrel wall after arrival.
