Abstract

The invention discloses a novel atrial fibrillation cryoablation device beneficial to pulmonary vein occlusion, and relates to the technical field of atrial fibrillation treatment. The device comprises a cryoballoon catheter and a handle, a pressure pump connecting port is formed in the right end of the cryoballoon catheter, a pressure pump is adaptively assembled at an end of the pressure pump connecting port, an annular mapping catheter, a pressure balloon and a cryoballoon are sequentially installed at the left end of the cryoballoon catheter, and an LED display screen and an emergency brake button are sequentially arranged on the outer wall of the middle of the handle; a guide sheath and a circuit connecting passage are arranged on the cryoballoon catheter, the annular mapping catheter is provided with a near end and a far end, a pushing sheath is arranged at the near end of the annular mapping catheter, and the farthest end of the annular mapping catheter is annular in a free state and can retract into the pushing sheath to be linear. The device has a good occlusion effect on pulmonary veins with complex branches, and has a function of emergently stopping cryoablation; and the operation efficiency and safety are improved.

Description

technical field [0001] The invention relates to the technical field of atrial fibrillation treatment, in particular to a novel atrial fibrillation cryoablation device which is beneficial to pulmonary vein occlusion. Background technique [0002] Atrial fibrillation is one of the most common clinical tachyarrhythmias. Epidemiological data show that the total prevalence of atrial fibrillation in my country is about 0.7%, and the incidence and prevalence gradually increase with age. Atrial fibrillation can lead to stroke and deterioration of heart function. It is an important cause of death and disability of patients, greatly reduces the quality of life of the population, and increases the social burden. Therefore, the treatment of atrial fibrillation is particularly important. For the treatment of atrial fibrillation, catheter ablation has been widely used in clinical treatment of atrial fibrillation, and its efficacy has been recognized by everyone. Among them, pulmonary ve...
