The Mechatronics in Medicine Laboratory develops robotic and mechatronics surgical systems for a variety of procedures including neuro, cardiovascular, orthopaedic surgeries, and colonoscopies. Examples include bio-inspired catheters that can navigate along complex paths within the brain (such as EDEN2020), soft robots to explore endoluminal anatomies (such as the colon), and virtual reality solutions to support surgeons during knee replacement surgeries.

AB - Steerable needles have the potential for accurateneedle tip placement even when the optimal path to a target tissueis curvilinear, thanks to their ability to steer, which is an essen-tial function to avoid piercing through vital anatomical features.Autonomous path-following controllers for steerable needles havealready been studied, however they remain challenging, especiallybecause of the complexities associated to needle localization. Inthis context, the advent of fiber Bragg Grating (FBG)-inscribedmulti-core fibers (MCFs) holds promise to overcome these diffi-culties. Objective: In this study, a closed-loop, 3-D path-followingcontroller for steerable needles is presented. Methods: The controlloop is closed via the feedback from FBG-inscribed MCFs embed-ded within the needle. The nonlinear guidance law, which is a well-known approach for path-following control of aerial vehicles, isused as the basis for the guidance method. To handle needle-tissueinteractions, we propose using Active Disturbance Rejection Con-trol (ADRC) because of its robustness within hard-to-model en-vironments. We investigate both linear and nonlinear ADRC, andvalidate the approach with a Programmable Bevel-tip SteerableNeedle (PBN) in both phantom tissue and ex vivo brain, with someof the experiments involving moving targets. Results: The mean,standard deviation, and maximum absolute position errors areobserved to be 1.79 mm, 1.04 mm, and 5.84 mm, respectively, for3-D, 120 mm deep, path-following experiments. Conclusion: MCFswith FBGs are a promising technology for autonomous steerableneedle navigation, as demonstrated here on PBNs. Significance:FBGs in MCFs can be used to provide effective feedback in path-following controllers for steerable needles
