Flexible and Expandable Robot for Tissue Therapies - Modeling and Design. | LitMetric

AI Article Synopsis

  • - The study introduces a flexible and expandable implantable robotic (FEIR) device designed to enhance tissue quality and minimize inflammation during tissue reconstruction by applying controlled tension to tubular tissues.
  • - A theoretical framework using iterative beam theory was developed to balance the stiffness and tension capabilities of the robot, which was validated through experiments with biological tissue.
  • - The findings highlight the robot's ability to deliver therapeutic forces effectively while reducing damage to surrounding tissues, showing promise for medical applications like treating Long-Gap Esophageal Atresia and Short Bowel Syndrome.

Article Abstract

Objective: Implantable technologies should be mechanically compliant with the tissue in order to maximize tissue quality and reduce inflammation during tissue reconstruction. We introduce the development of a flexible and expandable implantable robotic (FEIR) device for the regenerative elongation of tubular tissue by applying controlled and precise tension to the target tissue while minimizing the forces produced on the surrounding tissue.

Methods: We introduce a theoretical framework based on iterative beam theory static analysis for the design of an expandable robot with a flexible rack. The model takes into account the geometry and mechanics of the rack to determine a trade-off between its stiffness and capability to deliver the required tissue tension force. We empirically validate this theory on the benchtop and with biological tissue.

Results: We show that FEIR can apply the required therapeutical forces on the tissue while reducing the amount of force it applies to the surrounding tissues as well as reducing self-damage.

Conclusion: The study demonstrates a method to develop robots that can change size and shape to fit their dynamic environment while maintaining the precision and delicacy necessary to manipulate tissue by traction.

Significance: The method is relevant to designers of implantable technologies. The robot is a precursor medical device for the treatment of Long-Gap Esophageal Atresia and Short Bowel Syndrome.
