PROBLEM TO BE SOLVED: To solve the problems that there is no design specialized in NOTES of an edged tool itself since it is a novel and revolutionary surgery method even in the case of NOTES to be executed by two persons using together a single-hole type laparoscopic surgery in which an incision to an abdominal wall is narrowed to one part, a long diameter of a closed part to be a problem after a surgery increases, a digestive tract itself is narrowed or deformed causing a digestive tract movement closure, and that there is no device having a function of efficiently stopping a bleeding part of a digestive tract incision wound as a cause of major bleeding during incision, further.SOLUTION: A double inversion round cutter mechanism is provided for opening a precise circle with a round cutter with a circular blade tip with which cutter surface processing at a nano level is executed to guarantee sharpness so as to be safe and prevent tearing of an intestinal tract during NOTES executed by two persons during a NOTES surgery, and aiming at traction control for improving cutting efficiency of the round cutter. Further, a blood stopping and coagulating function to the round cutter for instantaneously stopping bleeding in an incision wound is provided. |
