In performing a surgical operation with the aid of a microscope or endoscope, stapling surgery is often applied to anatomosis or suture of a fine blood vessel by means of an autosuture device. As the first step leading to the development of stapling srugery, the measurements were made with stretching and bending characteristics of fine titanium wire together with fundamental dynamic properties of tensile and pressurized strength of pig's artery. Electrolytically polished titanium wire was employed as the stapling material, whereas the blood vessels of the pig and the cow were used as the biological tissue. Meanwhile with a view to making evaluation of the sutured part, by using an X-ray CT unit, it was examined in what a manner the artifact which tends to prevent from reliable diagnosis, would be generated.
