|発明の名称||BODY INSERTION TUBE SELF-ADHERING TO TISSUE, AND METHOD FOR ADHERING THE BODY INSERTION TUBE TO BODY ORGAN TISSUE|
PROBLEM TO BE SOLVED: To provide a body insertion tube capable of self-adhering to a tissue that is applicable to a combined low-energy adhesion method, and a method for adhering the body insertion tube to a body organ tissue in order to perform adhesion to the body organ tissue more quickly and easily than before and establish high adhesion strength without forming a gap that allows the invasion of bacteria.
SOLUTION: A body insertion tube is to be contacted with a body organ tissue and adhered thereto in a state of being coated with the body organ tissue. At the body insertion tube, on the side to be in contact with the body organ tissue, at least a groove, hole or depressed part having such a size that an anchoring effect can be obtained by the entry of the body organ tissue through deformation or displacement is formed, and a passage for applying a negative pressure to the groove, hole or depressed part, upon the adhesion of the body insertion tube to the body organ tissue, is formed.
