Abstract: A suture body includes: a suture thread having a first end and a second end and fixed to a living tissue; a suture needle connected to the first end; and a thread fixing member connected to the second end. The thread fixing member includes: a rod-shaped protruding portion; and an elastic member having an outer circumferential surface and arranged so that the thread fixing member is in contact with the outer circumferential surface at a predetermined contact pressure. The suture body is configured so that the suture thread can enter between the protruding portion and the elastic member by elastically deforming the elastic member. The suture body further includes a base body to which the protruding portion and the elastic member are fixed. The protruding portion and the elastic member are arranged in an area surrounded by an outer diameter of the base body.

Abstract: A tissue removal system is provided which enables optimally performing a full-thickness resection of a hollow organ while minimizing invasiveness. In this tissue removal system, a tissue pressing tool which has a tissue contacting part and which is guided into the abdominal cavity, and a resection and anastomosis device work together. The resection and anastomosis device resects and performs anastomosis of tissue positioned between a main body and an anvil part, and, when pressing the tissue to be cut to the cutting position of the resection and anastomosis device by means of the tissue contacting part, the tissue contacting part is pressed against two abutment parts of the resection and anastomosis device.
