1results about How to "High microwave power" patented technology

This invention discloses a microwave ablation electrode, relating to the field of medical device technology. It mainly includes a main needle body, whose working end can release microwave energy to achieve microwave ablation. The main needle body is equipped with a non-working end circulating cooling structure and a working end liquid injection structure. The non-working end circulating cooling structure allows a cooling medium to reach the non-working end of the main needle body to cool the non-working end and surrounding tissue, and also allows for the return flow of the cooling medium. The working end liquid injection structure allows a cooling medium to reach the working end of the main needle body to cool the working end and surrounding tissue, and also allows the cooling medium to be injected into the lesion tissue, absorbing microwave energy to form steam, achieving steam thermal ablation. This invention achieves dual ablation through steam thermal ablation and microwave ablation, improving the ablation effect, reducing the temperature of the working end of the microwave ablation electrode, and increasing the moisture content of the tissue surrounding the working end, thus reducing carbonization of the lesion tissue.
