Problems solved by technology
[0005] The technical problem to be solved in the present invention is: during the use of the existing ablation electrodes, some tumors, especially superficial lung tumors and subcapsular liver tumors, are not easy to fix after the ablation electrodes are punctured, which may easily cause the ablation electrodes to collapse. The depth and angle of the puncture will change

The invention relates to a fixator of an ablation electrode puncture appliance. The fixator of the ablation electrode puncture appliance is characterized by comprising an ablation electrode fixing sleeve (3) made of flexible and resilient materials; the ablation electrode fixing sleeve (3) wraps and fixes the ablation electrode puncture appliance (2); the ablation electrode fixing sleeve (3) is provided with a tightness degree adjusting mechanism used for adjusting the tightness degree for wrapping the ablation electrode puncture appliance (2); the ablation electrode fixing sleeve (3) is provided with at least two cotton ropes in a penetrating mode; one ends of the cotton ropes are connected with a human skin adhesion fixing device (4), and the other ends of the cotton ropes are free ends. The fixator can effectively fix the ablation electrode puncture appliance, it is avoided that as an ablation electrode collapses, the puncture depth and angle change, safety and stability are improved greatly, the structure is simple, materials of relevant components are obtained conveniently, and the fixator has very high clinical application value.
Description
Technical field [0001] The invention relates to a fixer and a fixation method of an ablation electrode puncture device and belongs to the technical field of medical devices. Background technique [0002] As a new effective and minimally invasive treatment technique for the treatment of primary and secondary malignant tumors, thermal ablation is receiving more and more attention from clinicians. Clinically, thermal ablation has been applied to the treatment of a variety of tumors, including liver cancer, kidney cancer, toxic thyroid, adenoma, and various metastatic cancers of the lung, brain, and retroperitoneum. However, CT-guided thermal ablation is used to treat liver and lung primary tumors. And secondary tumors are particularly noticeable. Foreign scholars have affirmed the effect of thermal ablation through a large number of experiments and clinical studies. [0003] During the CT-guided treatment of lung tumors and liver tumors, we found that because CT-guided ablation trea...
