Abstract

The invention relates to a high-performance water-cooled microwave ablation antenna with anti-microwave interference temperature measurement and ablation integrated. The antenna comprises a radiation head, a medium pipe, a semi-rigid coaxial cable, a needle bar and a thermocouple. A metal shield casing is arranged on the outer portion of the needle bar, and the temperature measuring end of the thermocouple is fixed on the inner surface of a metal shield. The high-performance water-cooled microwave ablation antenna with anti-microwave interference temperature and ablation adopts a precise antenna structure, and can reliably shield the microwave energy and microwave electromagnetic field from strong influence on the temperature measuring end, and solves the problems of microwave ablation antenna directly involved in the treatment of microwave ablation of the tumor while implementing the key technologies of real-time measurement of the temperature of its tissue, which may control temperature changes of tumor cell tissues in the process of microwave ablation surgical treatment in order to achieve the perfect therapeutic effect and purpose of microwave ablation of the tumor.

Description

technical field [0001] The invention relates to a water-cooled medical device with anti-microwave electromagnetic field interference, which integrates microwave ablation therapy while measuring the temperature of microwave ablation tumor tissue in real time, and is suitable for various medical devices such as chest, abdomen, pelvis, orthopedics, etc. The clinical operation of malignant tumor belongs to the application field of medical microwave technology. Background technique [0002] With the rapid development of modern high-tech and bioengineering, since the beginning of the 21st century, medical microwave technology has been widely used, especially microwave ablation of tumors has rapidly developed into a major means of clinical tumor treatment, due to its fast tumor heating speed, The outstanding advantages of high intratumoral temperature, large ablation range, and little influence from carbonization and blood flow are playing an increasingly important role in the trea...
