    • A coagulating cutter according to the present invention comprises: a transmitting member for transmitting energy, for treating living body tissue, to the living body tissue; an outer sheath through which the transmitting member is passed; and a grasping section supported at the tip end portion of the outer sheath so as to be capable of turning with respect to the transmitting member, which allows the living body tissue to be grasped against the transmitting member. With such an arrangement, upon turning the grasping section toward the transmitting member to be in a closed state, the faces of the transmitting member and the grasping section, which face each other, provide a contact portion, where the transmitting member and the grasping section are in contact with each other over a predetermined length, for incising the living body tissue grasped between the transmitting member and the grasping section, and a non-contact portion, where the transmitting member and the grasping section are provided with a predetermined interval on both sides of the axis extending in the direction of the predetermined length of the contact portion so as not to be in contact with each other, for coagulating the living body tissue.
    • 根据本发明的凝结切割机包括:传送部件,用于将生物体组织的能量传递给生物体组织; 传递构件通过的外护套; 以及抓握部,其支撑在所述外护套的前端部,以能够相对于所述传递部件转动,所述抓持部使得所述生物体组织能够抵靠所述传递部件。 通过这样的布置,当将把持部朝向传递部件转动到关闭状态时,传递部件和把持部分彼此面对的面设置有接触部分,在该接触部分处,传递部件和把持部分 彼此接触预定长度,用于切割夹持在传递部件和把持部之间的生物体组织和非接触部分,其中传递部件和把持部分在两者上设置有预定间隔 所述轴线沿着所述接触部分的预定长度的方向延伸以不彼此接触,以使所述生物体组织凝结。
