Description

Technical Field

[0001] The utility model relates to the technical field of arrhythmia ablation, in particular to an ablation device for arrhythmia. Background Art

[0002] Arrhythmia is a general term for the symptoms of irregular, fast or slow heartbeat caused by abnormalities in the heart's electrical conduction system. It can be treated with oral antiarrhythmic drugs or radiofrequency ablation surgery. Radiofrequency ablation surgery is to use an ablation device to puncture the femoral vein, femoral artery or subclavian vein and insert the electrode catheter into the heart under the monitoring of an X-ray angiography machine. The location of the arrhythmia is first determined and then high-frequency current is released locally. A higher temperature is generated within the range of the heart. Through thermal efficiency, the water in the local tissue is evaporated, and the local myocardial cells in specific areas are ablated to block the reentrant circuit or eliminate the lesions to treat rapid arrhythmias.

[0003] During cardiac radiofrequency ablation, the heart is ablated by inserting an ablation tube into the patient's body. In the existing ablation device, the medical staff fixes the ablation tube by hand during ablation. The ablation time is long and the heart beats up and down, which easily causes the ablation point at the front end of the ablation tube to be unable to fit the inner wall, reducing the ablation efficiency of the ablation device and increasing the operation time.

[0004] Therefore, those skilled in the art provide an ablation device for arrhythmia to solve the problems raised in the above background technology. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings existing in the prior art, and an ablation device for arrhythmia is proposed. The ultrasonic probe on the other side of the detection mechanism can quickly detect the location of the patient's arrhythmia, and the ablation device on the other side can locally release high-frequency current for ablation. The display screen can facilitate medical staff to watch and record the things that the ultrasonic probe has dropped dust on. The protective shell cooperates with the air bag and the groove inside to inflate the inside of the air bag when the medical staff inserts the detection mechanism into the patient's body. The detection mechanism and the protective shell can be fixed to the place where ablation is required, which can avoid the patient's heartbeat fluctuating differently during the ablation process, reducing the ablation efficiency of the ablation machine and increasing the operation time. The folding tube on one side of the ablation tube cooperates with the limit block set by the outer surface clamping and the linear motor at the lower end to adjust the length of the ablation tube according to the ablation position, which can facilitate ablation at different depths and increase the practicality of the ablation machine. The detection mechanism and the ablation machine can be connected by the connecting block and the connecting line, and the protective shell can be fixed to the outer surface of the detection mechanism by the fixing sleeve and the connecting block.
