Abstract
One of the clinical treatment of heart disorders has myoblast cell sheet transplantation. Because the myoblast cell sheet is weak, it is difficult to transplant it without the damage. There a device of the scooping mechanism which can be moved without breaking the cell sheet was developed. However, it is difficult to transplant the cell sheet to beating heart with it. We have developed the surgical robot with a heart-surface-motion synchronization mechanism for myoblast cell sheet transplantation. The purpose of this study is to develop a new robot having the bent for clinical application, which applied scooping mechanism to its transplant mechanism. A success rate and an average damage score in transplant with the robot system under experimental environment became 60% and 99.5±4.2%, respectively. The results of transplant simulation with an imitation cell sheet show that our robot system is better than manual operation using the device of the scooping mechanism.
