“…If the intracavitary device is large, a driveshaft with greater stiffness should be selected in order to allow the driveshaft to pass smoothly through the distal lesion path. When performing complex endovascular procedures, such as complex multi-stent vascular recanalization or the release of transplanted vessels, the high stiffness of the driveshaft ensures the integrity of the coating material and the corrosion and damage resistance of the driveshaft metal material [13]. Meanwhile, the influence of the operating frequency of the guide wire and other cooperating devices should be considered to avoid damage to blood vessels due to resonance.…”

A driveshaft is a small spring coil less than 1mm in diameter, composed of several stainless-steel wire filaments. In intervention, the driveshaft is used to transmit force and motion to the inside body through the existing micro channels (such as arteries, veins, and gastrointestinal tract). The performance of the driveshaft determines the efficiency, stability, and accuracy of force and motion transitions, the ability to pass through tortuous microchannels, and the damage to healthy tissues. To determine the influence of fabrication parameters (filament, wire diameter, and outer diameter) on the mechanical properties (such as bending stiffness and natural frequency) of the driveshaft, a simulation was established in ABAQUS to calculate the deformation displacement under 0.0098N and first-order natural frequency. Then, the bending stiffness is calculated. The results show that the bending stiffness and the first-order natural frequency of the driveshaft increase with the increase of the filament number and wire diameter, and with the outer diameter of the driveshaft increases, the bending stiffness increases, while the first-order natural frequency decreases. Finally, the simulation model is verified by measuring the deformation displacement in the experiment. This study provides a methodology for designing and selecting the driveshaft in Interventional therapy.
