Microfabrication of Components for a Novel Biomimetic Neurological Endoscope
2020Co-Authors: Andreas Schneider, L. Frasson, T. Parittotokkaporn, F. M. Rodriguez, Y Baena, Brian L. DaviesAbstract:The development of a novel biomimetic neurosurgical probe is inspired by nature. Some insects have spines with a unique surface texture which enables them to penetrate tissue more easily. This surface texture consists of cutting teeth and fin-like pockets on the spine. Instead of drilling, the insect slides its spine into the fibre through the reciprocating motion of independent segments. Applying the same or similar microtexture to a miniaturized neurosurgical Endoscope could improve existing tools for brain surgery and brain biopsy. The development of such Endoscope could minimize the damage caused by inserting the probe whilst avoiding the risk of buckling, which is a common occurrence when thin flexible probes are axially loaded. To replicate the surface microtexture, teeth and fin-like high-aspect-ratio microstructures were fabricated. Different geometries of these fins and teeth were studied for insertion into tissue so that the texture could be characterized for friction and tribological interaction with tissue. For these tests, free-standing long and narrow strips with microstructures in up to 525 µm thick SU-8 were designed, fabricated, and mounted onto prototypes made by stereolithography. This paper focuses on the fabrication of the microtextured strips. The required geometry of these strips can cause considerable bending. The structures were investigated regarding fabrication and stress conditions.
