Abstract
The utility model belongs to the technical field of medical instruments, and particularly relates to a microwave ablation needle. The utility model provides a microwave ablation needle, which aims to solve the problems of skin scald and carbonization of a central area of an ablation focus caused by heat accumulation of a needle point after an ablation needle in the prior art is used for a long time, and comprises an outer shell with an installation space inside, a needle rod is fixedly connected onto the outer shell, and an ablation needle head is arranged at one end of the needle rod. One end of the ablation needle head extends into the ablation needle, the other end of the ablation needle head extends into the mounting space, a cooling system is arranged in the mounting space, a conveying pipeline for conveying a cooling medium is arranged in the needle rod, and an internal temperature measuring ring is arranged between the conveying pipeline and the ablation needle head. The cooling medium can be sent to the ablation needle head through the needle head cooling cavity, so that the heat accumulation condition of the ablation needle head is effectively reduced, the phenomena of skin scald and carbonization of a central area of an ablation focus are reduced, and the shape of a solidification necrosis area of microwave ablation is improved.
