controllable bend helical perfusion catheter

Abstract

The invention discloses a medical catheter device, and provides a controllable bent and spiral irrigation catheter which comprises a handle, a control component arranged in the handle, a guide tube and a spiral ablation catheter body. The guide tube and the spiral ablation catheter body are connected with the control component, the spiral ablation catheter body is movably arranged in a cavity of the guide tube, a first traction fiber is arranged in the guide tube, a second traction fiber is fixedly arranged in the spiral ablation catheter body, and an electrode is arranged in the spiral ablation catheter body. The control component comprises a first control button, a second control button and a third control button, the far end of the spiral ablation catheter body is spiral, and one or more electrodes are arranged on the spiral section of the spiral ablation catheter body. The tail of the spiral far end of the spiral ablation catheter body is a straight section, and one or more electrodes are arranged on the straight section. The electrode or the catheter body is provided with one or more holes for spraying fluid. The controllable bent and spiral irrigation catheter can control the ablation catheter body at the far end to quickly reach an assigned tissue part for diagnosis and treatment, fluid is sprayed in the treating process, complications are prevented, and after treatment, if the treatment is complete is judged through the catheter, and the curing effect is effectively improved.

Description

technical field [0001] The invention relates to a medical catheter device, in particular to a medical controllable bending ablation catheter. Background technique [0002] Electrophysiological catheters have been widely used in medical practice. They are mainly sent to different lesions by subcutaneous puncture, and electrophysiological examinations and radiofrequency ablation are performed on pathological parts, so as to achieve the purpose of diagnosis and treatment of lesions. Electrophysiological catheters generally use single-stage ablation. If the lesion tissue area is large or the distance is too long, multiple ablation treatments are required, which will take a lot of time, and even a good therapeutic effect cannot be achieved because of incomplete ablation. [0003] During ablation treatment, in order to achieve a deeper ablation depth, higher ablation energy will be used clinically, which will often cause local overheating of the lesion tissue, cause various compli...
