For improved detection of these obstacles, surgeon and control algorithms would require 3-dimensional visual feedback using biplanar fluoroscopic imaging during electrode guiding and placement, or in combination with other imaging techniques, such as pre-operative MRI and trajectory modeling (Jonathan and Groen, 2005; Hong et al., 2015, 2019; Hu et al., 2018). Journal Papers goto. With these advantages, magnetically driven micro-/nanorobots address most disadvantages of the aforementioned propulsion mechanisms [42]. These concepts are discussed to describe the interactions between micro/nanorobots and magnetic fields. The most common complications of SCS implantation include electrode migration, hardware malfunction and fracture of electrodes, tolerance to SCS, infection, cerebrospinal fluid (CSF) leakage and pain or hematoma/seroma at the pulse generator site (Bendersky and Yampolsky, 2014). strategies (S1S6) to break the Scallop Theorem to produce biotinstreptavidin interaction under a magnetic field.
