Technical field
The present invention relates to medical nursing equipment technical field, in particular to a kind of tumor insertion thermotherapy instrument.
Background technique
For a long time, how effectively tumors destroyed, be academia and the High-Interest Object that clinical medicine circle is competitively pursued.It is swollen
For tumor thermotherapy compared with the cancer therapies such as operation excision, chemotherapy and radiation, brought side effect and nocuity are smaller, thus
It is known as " green remedy ".Tumor thermotherapy is that the temperature of tumor tissues and its surrounding tissue is promoted by various heating meanss, when
When tumor tissues are heated to certain temperature, so that it may tumour cell is killed, simultaneously because normal cell is heat-resist in swollen
Oncocyte so being not easy to be burnt under same heating condition, thus can protect normal tissue to a certain extent.
Both at home and abroad to body cavity digested road malignant tumour, such as the cancer of the esophagus, cholangiocarcinoma tumour, there are many treatment methods, remove
It is outer using operation excision, radiotherapy and chemical therapeutic method are mainly used, it is thin to tumour using various rays and chemicals
Born of the same parents play a part of to destroy or it are inhibited to grow, and reach therapeutic purposes.It is primarily present following problems: 1, radiotherapy is using big
From extracorporeal irradiation, large dosage of radioactive ray and chemicals while killing cancer cell, human normal tissue also has type equipment
It damages to a certain degree, toxic reaction such as bone marrow suppression, digestive tract reaction etc.；2, therapeutic effect is low, and patient can not obtain enough
Nutrition and make that sb.'s illness took a turn for the worse.Microwave is another important tumor therapeuticing method after radiotherapy, chemotherapy.Go out at present
Existing kinds of tumors thermal therapeutic apparatus, but also all structure is complicated for existing thermotherapy, heat insulation effect is bad.
