When the adipose tissue is fibrotic and too dense, the catheter can be deflected, and the surgeon must adjust the tip to redirect the catheter to the desired path. This setting would enhance the comfort for the patient and the surgeon. Reproduced with Magnetic navigation systems (MNS) are an emerging technology permitting precise and dynamic steering of surgical probes (Zemmar et al., 2020). Notably, increased operating time is a known risk factor for infection and revision surgeries trend toward longer operating times and thus higher infection rates.

Tolerance to SCS usually develops after 1 year in around 1029% of patients and often requires repeat surgery with alteration of the tip location (Taccola et al., 2020). An advantage of MNS would be that SCS leads could be placed outside an operating room (similar to a lumbar puncture, which can be done in a physician's office) through a Touhy needle into the epidural space. of a driller working in a 3D vascular network and experiment result However, SCS implantation can be associated with a relatively high injury rate, ranking spinal cord stimulator placement as the third-highest leading cause of injury among all medical devices after metal hip prostheses and insulin pumps (Taccola et al., 2020). combining active flagella-containing cells such as (G) bacterium, Based on these physical principles, researchers Huaijuan Zhou, Carmen Mayorga-Martinez, Salvador Pan, Li Zhang and Martin Pumera explain in their article Magnetically Driven Micro and Nanorobots published by ACS Publication how it is possible to control these small devices by means of magnetic fields to carry out targeted therapies at the . a single cell by peanut-like hematite microrobots.

On the other hand, increased steering freedom, would grant access to locations that are difficult to reach, such as dorsal root ganglia (Jonathan and Groen, 2005; Swaney et al., 2013; Caylor et al., 2019). Appl. MNS can reduce radiation exposure of healthcare workers (Yuan et al., 2017) as the procedure can be performed remotely, i.e., the surgeon is located outside the surgical suite behind a radiation barrier (Figure 2A).

Rotation of the external magnetic field will result in a rolling motion of the microrobot on the dura mater. 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).

Magnetically actuated micro/nanorobots are typical micro- and nanoscale artificial devices with favorable attributes of quick response, remote and contactless control, harmless human-machine interaction and high economic efficiency. Micro- or nanorobots are small-scale devices designed to perform minimally-invasive interventions and are powered by external power sources (Colberg et al., 2014; Zeeshan et al., 2014; Rao et al., 2015; Chen et al., 2017a; Soto et al., 2021).

MNS also allow for steering control at longer distances, e.g., the lead could be inserted at the thoraco-lumbar level (which is safer than more cranial insertion points) and guided to the cervical level, or a combined cervical and thoracic lead could be guided through a single entry and navigated to both targets. Micro/nanorobots are classified as magnetically driven, chemically driven, ultrasound-driven, light-driven, or electrically driven, depending on the power source used. the Advancement of Science. kidney cells when in targeted contact with helical microrobots loaded Schematic image and However, commonly used physical hybridization approaches can lead to blockages and damage to biological interfaces, impeding the optimal exploitation of natural abilities.
