摘要： The medical apparatus of this invention includes a therapeutic section at least having a blade for treating a living tissue thermally, a heat insulating part for insulating heat conduction from the blade to the main body of the medical apparatus. The therapeutic section and the heat insulating part are preferably provided on a grasping section (for example, a pair of jaws) for grasping the living tissue. It is preferable that the therapeutic section has a shape such that the living tissue and the side surface of the therapeutic section do not contact with each other. It is also preferable that the heat insulating portion has a shape such that the living tissue and the heat insulating portion do not contact with each other.

摘要： A surgical treatment device includes a shaft, a treatment portion which is provided at the tip of the shaft to effect heat treatment to living tissues, heater elements which are disposed in the treatment portion, a cable member which is inserted through the shaft to supply power to the heater elements, and a heat insulating member for inhibiting heat transfer from the treatment portion to the shaft. As the heater elements are disposed in the treatment portion consisting of a member having high heat conductivity, the heat generated by the heater elements can be efficiently utilized. In addition, as the heat transfer to the shaft is inhibited by a heat insulating member, heat loss is small. According to the surgical treatment device, coagulation treatment and blunt separation treatment can be efficiently carried out.
