Abstract

A puncture perfusion needle, a perfusion part, and an electrode head for tumor radiofrequency ablation. The puncture perfusion needle includes a puncture needle body, which is flat, and a plurality of first outer arcs are arranged on both sides of the needle body along its length direction. The needle head In the direction of the needle tail, the distance between the arc top of the outer arc and the axis of the needle gradually increases; the puncture and perfusion part includes at least two above-mentioned puncture perfusion needles arranged side by side. The radiofrequency ablation electrode head includes an electrode needle, an outer sleeve, and a puncture perfusion part or (isolating the perfusion component and the puncture perfusion part). The radiofrequency ablation electrode head of the present invention can effectively block the heat damage effect of radiofrequency ablation during the treatment process, eliminate the pain caused by the nerve stimulation of adjacent organs, perforate adjacent organs, reduce the pain of patients during operation, and improve the success rate of radiofrequency ablation treatment, thereby Reduce the number of operations for patients and reduce the local recurrence rate.

Description

technical field

[0001] The invention relates to the technical field of medical auxiliary devices, in particular to a puncture perfusion needle, an infusion piece and an electrode tip for radiofrequency ablation of tumors. Background technique

[0002] Recently, local thermal ablation techniques for many solid tumors have developed rapidly, and new minimally invasive ablation techniques have received extensive attention as an effective treatment option. Among the common physical ablation techniques, radiofrequency ablation is a kind of physical thermal ablation, which has been rapidly developed because of its safety and effectiveness. The radio frequency system also develops from the monopole system to the multipole system. Image-guided percutaneous radiofrequency ablation has gradually matured, its indications have been broadened, postoperative complications have been gradually reduced, and the efficacy has been further improved. It has become an indispensable method for th...
