Abstract
<p>Stable and less-invasive manipulation of soft organ is a key issue in endoscopic surgeries. In previous surgeries, slipping the organ would lead some damage or the risk of rapture. It would be required especially in tissue resection. We have been developing a device for assisting the organ stably by introducing pneumatic tuning of device stiffness. In this study, we investigated shape parameters of the device structure by numerical simulation using finite elemental method. The result showed that the width of pillars and the thickness of flat part affected the rigidity gain of device and the gain reached to 11.8 in maximum. The optimized shape parameters could contribute to safe and stable operation during the surgeries. </p>
