Flexible and Expandable Robot for Tissue Therapies – Modeling and Design

Objective: Implantable technologies should be mechanically compliant with the tissue in order to maximize quality and reduce inflammation during reconstruction. We introduce development of a flexible expandable implantable robotic (FEIR) device for regenerative elongation tubular by applying controlled precise tension target while minimizing forces produced on surrounding tissue. Methods: theoretical framework based iterative beam theory static analysis design an robot rack. The model takes into account geometry mechanics rack determine trade-off between its stiffness capability deliver required force. empirically validate this benchtop biological Results: show that FEIR can apply therapeutical reducing amount force it applies tissues as well self-damage. Conclusion: study demonstrates method develop robots change size shape fit their dynamic environment maintaining precision delicacy necessary manipulate traction. Significance: is relevant designers technologies. precursor medical treatment Long-Gap Esophageal Atresia Short Bowel Syndrome.
