Abstract

The invention provides a cryoablation system. The cryoablation system comprises a first purging part, a second purging part, a first one-way valve, drying equipment, an ablation needle connecting part and a heat exchange part, the first end of the first one-way valve is used for being connected with an air source, the second end of the first one-way valve is connected with the second end of the drying equipment, the second end of the drying equipment is connected with the first end of the heat exchange part, the second end of the heat exchange part is connected with the ablation needle connecting part, and the ablation needle connecting part is used for being externally connected with an ablation needle; the first end of the first purging part is connected between the drying equipment and the heat exchange part, and the second end of the first purging part is connected with the ablation needle connecting part; the first end of the second purging part is connected between the heat exchange part and the ablation needle connecting part, and the second end of the second purging part is connected to a recovery device or the atmosphere; furthermore, the problem of ice blockage of a system pipeline in the using process is solved.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a cryoablation system. Background technique [0002] Cryosurgery, also known as cryotherapy, refers to a clinical medicine that uses low-temperature machinery to control the lesion group to experience cooling, freezing and rewarming to cause irreversible damage and even necrosis. It can be used to remove lesions or repair defects in the body to restore and improve body functions. Therefore, low temperature surgery is a very effective method for treating tumors. It has the advantages of minimal trauma, anesthesia and analgesia, reduced hemostasis, mild reaction, and prevention of tumor spread. The cryotherapy of tumor is to insert several cryoprobes equipped with thermocouples that can be individually controlled into the tumor site, and apply low temperature to the head of the cryoprobe to kill the tumor. The basic principle of cryotherapy for tumors is to form ice crystals insid...
