摘要

This paper explores the design, physical prototyping, and mechanical characterization of a haptic feedback system to be implemented in the simulation of Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA) surgery. This technique is performed in extreme emergency situations, whereby it is hard to organize training on the patient under risk-free and controlled conditions. This constitutes the strong motivation for the realization of a simulator. The haptic feedback system consists of two different devices, each developed from an original concept and equipped with specific functions: a “push” device to simulate the axial force exerted on the catheter and perceived through haptic feedback by the surgeon; and a “torque” device to tighten or release the catheter when necessary, transferring torque resistance to the surgeon. After an in-depth analysis of the state of the art, the design is carried out with the aid of CAD and CAE software. The main components are manufactured through rapid prototyping techniques. The prototypes are tested qualitatively and quantitatively, proving their correct functionality in exerting sufficient force feedback.
