Extending being present in suture direction, in order the 1st grip gearwheel board component and, the 2nd grip gearwheel board component and the housing and the aforementioned 1st grip gearwheel board component and the aforementioned 2nd grip gearwheel board component in each case to be jointed by the fork which was formed, at least, on the one hand to possess the aforementioned 1st grip gearwheel board component and the aforementioned 2nd grip gearwheel board component 1 pitches with the grip gearwheel Drive section which it makes face makes move in the longitudinal direction, to grip the suture section vicinity of organ system the organ grip feature which is formed (3) and aforementioned organ grip feature 3 outside counterIn order to make the moving range move, outside is formed limiting to when to the position where coincide with the Tip counter feature (5) and the aforementioned sudden thorn gearwheel and the Tip of the aforementioned scooping gearwheel it is, counter feature outside aforementioned the aforementioned organ grip feature due to (5) outside (3) makes the outside reaction work possible the anastomosis vessel which features that it has the counter management tools (1) is. According to the anastomosis vessel which relates to this invention, it can lighten the burden to organ system.縫合方向に延在して形成されたフォークに、第1の把持歯板部材と、第2の把持歯板部材と、ハウジングと、前記第1の把持歯板部材と前記第2の把持歯板部材の少なくともいずれか一方に接続され、前記第1の把持歯板部材と前記第2の把持歯板部材とを長手方向に1ピッチ分相対移動させる把持歯駆動部とを有し、器官組織の縫合部近傍を把持するように構成された器官把持機構(3)と、前記器官把持機構3を外反移動範囲を移動させるように構成された外反機構(5)と、前記突刺歯の先端部と前記すくい歯の先端部とが合致する位置にある場合に限定して、前記外反機構(5)による前記器官把持機構(3)の外反動作を可能とする外反管理手段を備えることを特徴とする吻合器(1)である。この発明に係る吻合器によれば、器官組織への負担を軽減することができる。
