Abstract
In this study we focus on the microsurgery that is surgical operation using operative microscope. Only a special trained microsurgeon can perform the microvessel anastomosis operation. As for the microvessel anastomosis operation, a maneuver is mainstream. However, the operation by the maneuver is easy to come to have a long time, and the burden to depend on a patient is big. In addition, bad points such as the fear of a leak and the secession by the roughness of the sewing width exist. Therefore, is this study; for the purpose of shortening of the blood vessel anastomosis time in the operation, the reduction of the burden on patient by it, the reduction of the degree of difficulty of the microvessel anastomosis operation, I develop a thread and the new anastomosis device for the maneuver using the needle.
