Title:
ANASTOMOTIC BUTTING MATERIAL
Document Type and Number:
Japanese Patent JP3531000
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To prevent anastomotic failure, bleeding, etc., and to execute sure anastomose by once operation by forming a staple prosthesis part with an opening at a center part as an anastomotic prosthesis material.
SOLUTION: A anastomotic prosthesis material 1 is formed by providing the doughnut-shaped staple prosthesis part 3 and a cylindrical fitting part 4 with a coaxial opening 2 in a center. At the time of using it, in the case of anastomosing a cut-off bowel e.g. an anvil part 9 to which the material is fitted is inserted to one of the cut-off parts of the bowel and an automatic anastomosing device main body 7 mounting the material 1 to a staple housing part 5 is inserted to the other of the cut-off parts. Then, a trocar is put out by penetrating a parietal from the opening of the material 1 and after connecting an anvil shaft 8, both of 6 and 8 are housed in the main body 7 to be stapled and at the same time, the inner surface of the staple is cut off to pull out the main body 7 from an enteric canal and the cut-off part of the bowel is sewn to anastomose the enteric canal.
