Level, number of the infected account for about the 21.8% of the whole world.With China human mortality aging aggravation and socio-economic development, industrialization, city
City's progress faster, environmental factor, life style constantly change, and the situation is tense for China's tumour prevention and control.
Traditional treating malignant tumor mode mainly has surgical resection, anticancer drug therapy (chemotherapy), radiotherapy
(radiotherapy), Chinese medical and herbal therapy etc..But surgical resection is often traumatic larger, some position operating difficulties it is big and for
Subclinical transfer stove is invalid；It is secondary often to there is different degrees of poison while obtaining therapeutic effect for the poor selectivity of chemotherapeutics
Effect；Radiotherapy also has toxic reaction at a specified future date；Chinese medical and herbal therapy mitigates frequently as the adjunctive therapy of operation, chemotherapy, radiotherapy
Complication for patients.The Microwave Coagulation Therapy tumour gradually risen in recent years is small with its operation wound, heating rate is fast, temperature in tumor
High, postoperative easy the features such as restoring, precisely treating, plays more and more important in the treatment that entity tumor is especially larger tumour
Effect, the popularity rate of clinical application is also higher and higher.
Microwave Coagulation Therapy tumour is that microwave ablation antenna percutaneous puncture is entered tumor group under image technology guidance
It knits, under microwave electromagnetic field action, the polar molecule vibration at high speed in tumor tissues generates high temperature, keeps oncoprotein matter molecule high
Temperature denaturation achievees the purpose that inactivate tumour.Currently, the neoplasm necrosis tissue of patient's body will continue to after microwave ablation is performed the operation
It in Remained mass, is swallowed and absorbs by own cells by the repair function of human body itself after the several months, dissipate, partially will form fiber scar
Trace, but the process is slowly (few then several months, more then several years), and has fever, secondary infection, Tumoral survival easy to recur etc. scarce
Point.
