Ablation needle tube, microwave ablation needle and microwave ablation therapeutic instrument

Abstract

The embodiments of the invention provide an ablation needle tube, a microwave ablation needle and a microwave ablation therapeutic instrument, and relates to the field of medical instruments. The ablation needle tube is provided with at least two channels which are isolated from each other, wherein at least two channels comprise a first channel and a second channel; the far end and the near end ofthe first channel respectively penetrate through the far end and the near end of the ablation needle tube, so a radio frequency cable passing through the first channel can be electrically connected with a radiation antenna arranged at the far end of the ablation needle tube; the first channel is used for containing a cooling liquid for cooling the ablation needle tube; and the far end and the near end of the second channel penetrate through the far end and the near end of the ablation needle tube respectively, so a connecting cable passing through the second channel can be electrically connected with an auxiliary element arranged at the far end of the ablation needle tube. The ablation needle tube provided by the invention can enable the radiation antenna to work normally, can enable an auxiliary element to work normally, has diversified functions, and can assist a minimally invasive surgery to be carried out better.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an ablation needle tube, a microwave ablation needle and a microwave ablation treatment instrument. Background technique [0002] Lung cancer ranks first among malignant tumors in terms of morbidity and mortality in my country and even in the world. At present, lung cancer or lung lobes are resected through thoracotomy or thoracoscopic surgery, or combined with traditional drug chemotherapy. With the rapid development of the medical industry, minimally invasive treatment is increasingly becoming the first choice of patients. [0003] As a minimally invasive surgery, microwave ablation is more and more widely used. Microwave ablation uses the thermal effect of microwave biological tissue. The microwave energy is transmitted to the distal end of the flexible ablation needle through the ablation line and radiates to the tumor lesion tissue to stop bleeding and coagulate the lesion tis...
