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). Drag forces, that are often a limiting cause for targeted micro- and nanorobot delivery, may not need to be considered in the epidural space, as little flow is present. Turner J. Recent developments in magnetically driven micro- and nanorobots. Superparamagnetic nanoparticles are widely used to construct magnetic micro/nanorobots and can be used as T2 contrast agents. fish-like nanoswimmer under an oscillating magnetic field. The Apart from H 2 O 2, hydrazine (N 2 H 4) was also used as fuel to propel micro-/nanorobots chemically (Ibele et al. Even with the lowest reported incidence of 2% (Gazelka et al., 2015), when considering the high volume of SCS procedures worldwide, this percentage still corresponds to a considerably high number of patients. After initial lead placement, the clinical effect of SCS is tested. (B) Delivery and patterning of POS Terminal Word Template 15357 | PoweredTemplate.com. (2013).

Many researchers have selected magnetic fields as the active external actuation source based on the advantageous features of this actuation strategy such as remote and spatiotemporal control, fuel-free, high degree of reconfigurability, programmability, recyclability, and versatility. Reproduced When the lead has been successfully navigated to the target location, surgeons can proceed as usual and connect an IPG manually. Electrode migration occurs in 1322% of SCS patients (Taccola et al., 2020), is more common with the less invasive percutaneous technique, and has been reported as the most frequent reason for repeat surgery (Turner et al., 2004), resulting in increased risk for the patient and additional operative time and cost.
