Problems solved by technology

[0010] In order to overcome the current situation that the radiation generated by various tumor hyperthermia due to improper heating methods leads to inaccurate temperature measurement of hyperthermia equipment and the estimation of poor treatment results caused by heating, the present invention provides a minimally invasive electrothermal probe for tumors with precise measurement and control. Needle medical devices, this brand-new hyperthermia method, can provide precise, real-time, controllable, and constant temperature to tumors, and inactivate tumors of any shape and 100% of tumor cells at one time without Damage adjacent normal tissue cells

Embodiment Construction

[0037] Each probe heating needle works independently and supplies power independently. The power supply is an independent regulated voltage and current DC power supply. The power supply voltage can be selected within the safe range of 36V.

[0038] In order to reduce the wire diameter and reduce the current as much as possible, the current limit of the power supply is limited to 200mA. When the temperature is heated to 45°C, the balance current will not exceed 100mA. The power does not exceed 7.2W.

[0039] When the probe heating needle is powered, the heater starts to heat up. The initial body temperature is 36.5°C, the voltage is lower than 36V, and the saturation current is 200mA. When the temperature rises to 45°C, the temperature sensor in the probe heating needle corresponds to a resistor, and the resistance value at this time represents 45°C, the system enters a steady flow state, the current will be lower than 200mA, and the temperature will remain at 45°C.

Abstract

The invention provides combined probe type tumor thermal-therapeutic apparatus capable of accurately measuring and controlling temperature. The combined probe type tumor thermal-therapeutic apparatus mainly adopts a reverse temperature control inactivation tumor therapeutic method which controls and determines the heating action in the tumor according to the induced temperature on the tumor margins. The apparatus has a function of performing selective thermal damage to biological tissues, so that by using the apparatus, any length of heating time for clinical treatment of tumors of any irregular shape can be obtained, and the probability that 100 percent of tumor tissues are completely inactivated for one time, but normal tissues around the tumors are not harmed, which is an important medical aim in clinical biomedicine, is realized.

Description

1. Technical field: [0001] The invention relates to the fields of electrothermal sensing technology and automatic control technology. This program can be directly applied to the clinical practice of tumor hyperthermia. 2. Background technology: [0002] Tumor hyperthermia, as a treatment method for tumors, has gone through a long process from formal proposal to popularization. At the beginning, some new hyperthermia technologies reported many encouraging clinical results, but most of them belonged to Phase II clinical trials, and there was still a certain gap from the generally accepted Phase III clinical trials ("Tumor Hyperthermia Technology and Clinical Practice". P107. Liu Jia. Director of Thermotherapy Department, Department of Radiation Therapy, Hunan Cancer Hospital. 2009.8). For example: 1. Microwave hyperthermia technology, because of the successful development of the needle-type monopole microwave antenna, the microwave energy can be concentrated on the needle ti...
