Patent ID: 7780624

Claim:
An apparatus for treating tumors using liquid stored in an outside storage tank, comprising: a main body coupled to the storage tank and having a supply tube and a discharge tube, through which the liquid circulates; a therapeutic member coupled to an extension pipe, which is coupled to the main body and surrounds the supply tube and the discharge tube, with a cavity defined in the therapeutic member and connected to the supply tube and the discharge tube, the cavity being supplied with the liquid; and a temperature sensing unit including a temperature sensor and a sensor pipe containing the temperature sensor, an end portion of the temperature sensing unit protruding from the therapeutic member through a temperature sensor guide hole formed in the therapeutic member to measure a temperature of a treatment area of a patient, wherein a distal end of the temperature sensor is exposed to the treatment area through a cutting hole formed in the sensor pipe, and a thermal insulator is provided in the cutting hole to surround the temperature sensor to prevent the temperature sensor from being affected by heat of the liquid that circulates in the therapeutic member.
