Patent ID: 7527590

Claim:
An endoscopic system comprising: a flexible endoscope which is insertable into a first tubular organ from a natural opening of a human body; an opening member which is inserted into the first tubular organ via the endoscope and forms on a wall part of the first tubular organ an opening used to insert the endoscope into an abdominal cavity from the first tubular organ in the body; a damage preventing member which prevents an organ outside the first tubular organ from being damaged by the opening member, before the opening member forms the opening on the wall part of the first tubular organ; an anastomosing device that includes a flexible tube having a distal end and portion which is inserted into an interior of the first tubular organ through the natural opening through which the endoscope is inserted and having a proximal end portion located outside the human body, and that includes an anastomosing member which is provided at a distal end portion of the flexible tube and operated from outside of the human body to anastomose a periphery of the opening formed on the wall part of the first tubular organ with a second tubular organ in the abdominal cavity, the anastomosing member having a suture thread having at least one end to suture organs and a curved needle, and the anastomosing member being adapted to achieve anastomosis by sewing the first tubular organ and the second tubular organ with the suture thread inserted therethrough in a loop, thereby substantially coupling the first tubular organ and the second tubular organ; and a second tubular organ cutting member that is inserted into the first tubular organ via the endoscope after the first tubular organ and the second tubular organ are coupled, and that cuts the second tubular organ, thereby communicating the interior of the first tubular organ with an interior of the second tubular organ.
