Research Abstract |
Recently, transplantation surgery based on tissue engineering is strongly expected to cure inextirpable disease or congenital failure effectively. Transplantation surgery in an eye is one of the most challenging medical technologies because an eye has only tiny surgical field and is very fragile. Therefore, it is expected to develop the minimally inversion medical technology for transplantation surgery in an eye. We have interested in the Retinal Pigment Epithelium(RPE) sheet transplantation and developed a transplantation surgical tool using pneumatic balloon actuator(PBA). Toward design optimization of pneumatic balloon actuators(PBAs), we have performed FEM simulation and demonstrated its applicability to compute and characterize the bending motion of PBAs fabricated from PDMS(polydimethylsiloxane)-based materials. It is shown that typical PBA motions could be successfully captured in the present simulation through the comparison of the computational results obtained in the linearly-elastic region with the actual motions of fabricated devices. Successive ex-vivo and in-vivo experiments through collaborations will verify the practical usability of the improved tool.
