Problems solved by technology

[0004] However, the current Symplicity ablation catheter still has certain defects, for example: 1. The operator needs to retract the catheter by himself, and it cannot be positioned accurately; 2. The degree of apposition cannot be accurately judged; 3. The distance between each ablation point cannot be accurately measured distance

Abstract

The invention relates to an electrical ablation balloon radiofrequency catheter in the percutaneous renal artery. The electrical ablation balloon radiofrequency catheter comprises a catheter, an electrical ablation balloon and an ablation electrode plate, wherein the tail part of the catheter is provided with a connector, the head end of the catheter is provided with the electrical ablation balloon, the electrical ablation balloon is communicated with a contrast agent filling pipeline through the catheter, the contrast agent filling pipeline is arranged in the catheter and passes through the connector to be connected with a pressure pump with contrast agents, the outer surface of the electrical ablation balloon is provided with the ablation electrode plate in spiral arrangement, the ablation electrode plate is connected with a radiofrequency ablation instrument through a conducting wire, and the conducting wire is embedded in the catheter, enters the connector from the tail part of the catheter and extends out from a port of the connector. The electrical ablation balloon radiofrequency catheter has the advantages that the operation is simple and convenient, the positioning is precise, the leaning is reliable, and the manual error and the operative complications possibly generated in the operation process are reduced to the greatest degree.

Description

Technical field [0001] The present invention belongs to the field of radio frequency discharge pipe device through the skin renal artery, especially involving a radio frequency pipe tube of the electroelectric melting ball cylinder in intramuscular renal arteries. Background technique [0002] In recent years, a new technique for the treatment of refractory hypertension for the treatment of refractory hypertension for the treatment of neurotated neurotated neurotated neurotated neurotoscopy in the world.This method cuts the kidney sympathetic nerves through radio frequency discharge, and does not affect other abdominal, pelvis or lower limbs nerve dominance, and achieves the purpose of avoiding severe complications while lowering blood pressure. [0003] Nephrine sensation nerve ablation is widely developed worldwide, applied in the treatment of refractory hypertension, and achieved significant curative effects.At present, the commonly used melted tools are Sympling catheters dev...
