1. A thermotherapy apparatus which is inserted in a body cavity through a medical tool in order to perform thermotherapy of a diseased part of a tumor in a living body, comprising;
- a probe sized for insertion in a body cavity through an endoscope, said probe having a distal end portion adapted to project into the body cavity through an endoscope;
a heating portion provided in said distal end portion, and having a far-infrared radiation ceramic member and a heater for heating said far-infrared radiation ceramic member;
wherein said probe has an elongated guide tube adapted to be inserted in an endoscope, and a mounting member, one end of which is fixed to a body cavity side of said guide tube, said far-infrared radiation ceramic member of said heating portion being mounted on the other end of said mounting member;
wherein said far-infrared radiation ceramic member is formed to have a cap-like shape having a closed end portion at the side of a body cavity, said heater being arranged therein.

Abstract
Thermotherapy apparatus used for performing a thermotherapy for a diseased part of a tumor such as a cancer of a living body. A heating portion is arranged in a distal end portion at the body cavity side of a probe which can be inserted in the body cavity through an endoscope or the like or a distal end portion at the body cavity side of an insertion portion of the endoscope. The heating portion has a far-infrared radiation ceramic member, and a heater for heating the far-infrared radiation ceramic member.
