This treatment system includes a support portion having a longitudinal axis, a distal end of the support section a first holding member and second holding member disposed on a side, with the first being connected to the said two gripping members grip member, the supporting part movable operating member along the longitudinal axis of the , wherein by moving the operating member, the operating part for causing the approach and away from each other said first gripping member and the second gripping members, the said second said first holding member toward the gripping member a first piercing member formed so as to protrude, and a contact portion provided at the distal end of the first piercing member, provided at a position opposite to said first piercing member, said first gripping member in towards the second piercing member formed to protrude from said second holding member, a blade portion provided at the distal end of the second piercing member, said first holding member and the second and thereby close the gripping member from a position apart from each other, and a closing mechanism for the contact state in which the cutting face and said abutment portion is polymerized in contact.この処置システムは、長手軸を有する支持部と、前記支持部の先端側に設けられた第一の把持部材および第二の把持部材と、前記第一の把持部材と前記二の把持部材とに連結され、前記支持部の長手軸に沿って移動自在な操作部材と、前記操作部材を移動させて、前記第一の把持部材と前記第二の把持部材を互いに接近および離間させるための操作部と、前記第二の把持部材に向かって前記第一の把持部材から突出して形成された第一の穿刺部材と、前記第一の穿刺部材の先端部に設けられた当接部と、前記第一の穿刺部材に対向した位置に設けられ、前記第一の把持部材に向かって前記第二の把持部材から突出して形成された第二の穿刺部材と、前記第二の穿刺部材の先端部に設けられた刃部と、前記第一の把持部材と前記第二の把持部材とを互いに離間した位置から接近させて、前記刃面と前記当接部とが当接して重合した当接状態にする開閉機構とを有する。
