Abstract

The invention relates to a cryoablation system capable of preventing fluid leakage. The system is composed of cryoablation equipment and a cryoablation catheter. The cryoablation equipment comprises ahuman-computer interaction module, a control module and a gas path module. A human-computer interaction module is electrically connected with the control module. The control module is electrically connected with the gas path module. The gas path module is connected with the cryoablation catheter. The cryoablation catheter includes a catheter slender shaft. A catheter handle is arranged at the proximal end of the catheter slender shaft, a freezing unit is arranged at the distal end of the catheter slender shaft, and an intake pipe and a return pipe are arranged in the cavity of the catheter slender shaft. The intake pipe and the return pipe are communicated with a fluid in the inner cavity of the freezing unit. A water vapor sensor is arranged in the cryoablation system, is communicated with a fluid in the catheter slender shaft, and is electrically connected with the control module. The system can effectively detect and prevent the safety risks of catheter liquid leakage and greatly reduce the risks in the application process of the cryoablation system.

Description

technical field

[0001] The application belongs to the field of minimally invasive interventional therapy, and in particular relates to a cryoablation system capable of preventing fluid leakage. Background technique

[0002] Cryoablation is a new technology in the treatment of cardiac arrhythmias. The principle is to take away the tissue heat through the heat absorption and evaporation of the liquid refrigerant, lower the temperature of the target ablation site, and destroy the abnormal cells and tissues, so as to achieve the purpose of treatment. The catheters used in cryoablation need to go inside the human body and go deep into the lesion. The interventional catheter of any cryoablation system generally has the risk of being damaged, causing blood to enter the catheter and causing partial blood loss to the patient. In addition, if the air pressure at the damaged catheter is greater than or equal to the blood pressure at the location of the catheter in the human body, the ...
