Soft Robotics for Minimally Invasive Surgery
Research Guide
What is Soft Robotics for Minimally Invasive Surgery?
Soft robotics for minimally invasive surgery uses compliant materials and bioinspired designs to create steerable needles, soft endoscopes, and colonoscopes that enhance dexterity in confined anatomies.
This subtopic integrates soft actuation, sensing, and continuum mechanisms for tissue manipulation under imaging guidance (Runciman et al., 2019, 486 citations). Key advances include fluid-driven soft muscles (Li et al., 2017, 701 citations) and perceptive soft robots (Wang et al., 2018, 699 citations). Over 20 papers since 2016 review designs like pneumatic actuators (Xavier et al., 2022, 313 citations) and magnetic microrobots (Jeon et al., 2018, 279 citations).
Why It Matters
Soft surgical robots reduce tissue trauma in procedures like endoscopy and needle steering, enabling access to anatomies unreachable by rigid tools (Runciman et al., 2019). Continuum manipulators improve navigation in vascular networks (Walker, 2013; Jeon et al., 2018). Perceptive soft grippers enhance safe tissue interaction (Hughes et al., 2016; Wang et al., 2018), with applications in cardiac and laparoscopic surgery (Mohr et al., 2001; Beasley, 2012).
Key Research Challenges
Actuation in Confined Spaces
Soft actuators must generate sufficient force in small anatomies without damaging tissue (Runciman et al., 2019). Fluid-driven designs like origami muscles face scaling issues (Li et al., 2017). Pneumatic systems require precise control models (Xavier et al., 2022).
Integrated Sensing Reliability
Embedding sensors in soft materials for real-time feedback remains challenging amid deformation (Wang et al., 2018). Triboelectric nanogenerators enable self-powered perception but need biocompatibility validation (Jin et al., 2020). Verification under surgical imaging is inconsistent (Jeon et al., 2018).
Control Under Uncertainty
Continuum robots exhibit hyper-redundancy, complicating kinematic modeling (Walker, 2013). Hybrid rigid-soft systems demand adaptive algorithms for MIS (Hughes et al., 2016). Clinical translation faces regulatory hurdles (Beasley, 2012).
