an ablation electrode

Abstract

The invention relates to the field of pain ablation, in particular to an ablation electrode. The ablation electrode comprises a flexible tube body, a support component and an electrode, wherein the flexible tube body is a hose made of biocompatible materials; the two ends of the flexible tube body are provided with open holes; the flexible tube body can bend, and comprises a free end; the support component is arranged in the flexible tube body in a penetrating way, and can be extracted out from the non-free end of the flexible tube body; one end of the support component can penetrate out of the free end of the flexible tube body; and the electrode is arranged at the free end of the flexible tube body, and can release the radio frequency energy. The invention aims at providing the soft and flexible ablation electrode with the advantages that the attaching effect is good; the operation difficulty is reduced; a contrast agent is uniformly distributed; and the puncture effect is good.

Description

technical field [0001] The invention relates to the field of pain ablation, in particular to an ablation electrode. Background technique [0002] Radiofrequency ablation technology is used for nerve therapy, soft tissue injury and reducing intervertebral soft tissue pressure, such as trigeminal neuralgia, lumbar disc herniation and other diseases. Radiofrequency ablation is to insert a puncture needle into the diseased tissue, release radiofrequency energy through the electrode needle, and form a The loop, through the Joule heat generated by the ion conduction current in the biological tissue and the heat generated by the dielectric loss of the biological tissue in the high-frequency electromagnetic field, causes the temperature of the diseased tissue to rise, so as to achieve the purpose of treatment, and the scope and effect of the treatment are the same as those of the tissue. The temperature is related to the temperature received, and the temperature is determined by the...

Problems solved by technology

[0003]Traditional puncture point needle or blunt needle, because the needle is fixed and curved, cannot reach the treatment site well, such as: the curved shape should not be too large, and the curved shape is too big Affect the puncture effect, otherwise it will lead to unsatisfactory adhesion and affect the treatment effect; traditional puncture needles can only be used for monopolar or bipolar ablation, and the conventional electrode length is fixed at 5mm, 10mm or 15mm, and the ablation length and range cannot be controlled during ablation; For multi-point ablation or pulsed radiofrequency treatment, it is necessary to insert multiple puncture needles for treatment, which increases the pain of the patient and increases the difficulty of the operation process; when the nerve root is observed through the contrast medium, the contrast medium distribution of the traditional puncture needle is uneven
