Researchers at the University of Texas at Austin developed a modular mechatronic framework to robotize and enhance the control of existing commercial endoscopes, featuring a novel gripping mechanism, a feeder mechanism, and an intuitive user interface. The framework's analytical model accurately predicted collet jaw displacement with a worst-case error of 0.72mm, enabling a 67% increase in grip range and demonstrating successful navigation in a phantom.
Key insights
- A mathematical modeling approach for the collet mechanism accurately predicts jaw deflection and establishes a design space for optimal mechanical parameters, reducing the need for extensive FEA.
- The modular design allows for versatile compatibility and easy installation on various existing commercial endoscopes, eliminating the need for custom-fabricated scopes and simplifying adoption.
- The intuitive joystick interface and simultaneous DoF control aim to reduce clinician cognitive load and learning curve, potentially improving procedural focus and reducing fatigue.
