3A1-G03 Development of the cell sheet transplantation-assist device which can manipulate the hydrogel with air pressure, and evaluation on transportation in the operating theater(Medical Robotics and Mechatronics (1))

Abstract

Purpose of this study was development of the new devices that could manipulate a hydrogel as a support for the cell sheet with air pressure. With reference to the stamp-type device to be used for the cell sheet stacking, the convex-type device for limiting the contact area with the support of the cell sheet was developed. The device was evaluated by measuring suction force to hold the hydrogel and by transport experiment considering clinical usage. It was confirmed that the developed device had enough suction force to hold the hydrogel. The hydrogel using the convex-type device failed to transport in the case of vacuum break. The reason why vacuum break occurred was that surface of the device could not follow the deformation of the hydrogel due to hardness of the device.
