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. |
