<P>PROBLEM TO BE SOLVED: To provide a vascular anastomosing instrument with which blood vessels can be accurately anastomosed through an easy operation. <P>SOLUTION: This vascular anastomosing instrument 1 includes a pair of rings 2 and 3 to be respectively inserted to the inner side of incisions formed in two blood vessels, and threads 4 and 5 spanningly laid between the rings 2 and 3 to connect them. The vascular anastomosing instrument 1 is so configured that, by pulling the threads 4 and 5 from the exterior of the blood vessels, the rings 2 and 3 are drawn closer to each other, and edge portions of the incisions in the two blood vessels are clamped between the rings 2 and 3. Also, the vascular anastomosing instrument 1 further includes fastening members 6 and 7. The fastening members 6 and 7 function as a holding means for holding the condition where the rings 2 and 3 are drawn close to each other, by fastening outer circumferential portions of the rings 2 and 3 through the vessel walls of the blood vessels. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
