2A1-Q07 Construction of Hybrid Circulatory system for Bionic Simulator(Medical Robotics and Mechatronics(2))

Abstract

In this paper, we propose the hybrid circulatory system for the realization of a bionic simulator using isolated organ tissue. To achieve the hybrid circulatory system, we use a heart isolated from chick embryo, and perform the concurrent microvascular anastomosis by using suction-induced vascular fixation (SVF) method. SVF method is a technique to fix the position and orientation of the vessels by sucking them through the pattered sheet, which can decrease the DOF of the vessels and make it easy to anastomose. Through the experiments, we confirm that the positioned attitude of 4 simulated cardiovascular can be controlled at one time by using developed micromanipulator. Finally, we have succeeded in connecting the Alg tubes with the blood vessels led to the heart of chick embryo.
