Problems solved by technology
[0003] To sum up, the problems existing in the existing technology are: the temperature detection during the ablation process of the existing cryoablation needle is inaccurate; at the same time, due to the patient’s respiratory displacement, body position change, and the doctor’s own operating experience, the actual needle insertion position during the operation Deviating from the preoperatively planned needle insertion position, if ablation is still performed according to the originally planned ablation conditions at this time, it may lead to incomplete ablation

Description
technical field [0001] The invention belongs to the technical field of cryoablation, and in particular relates to a cryoablation needle and an ablation system thereof. Background technique [0002] The existing cryoablation needle has two working modes of freezing and ablation. First of all, in the freezing mode, liquid nitrogen is delivered to the working part of the needle tip through the input pipeline. The extremely low temperature liquid nitrogen forms an ice ball at the needle tip, which exchanges heat with the surrounding human tissue, and freezes and kills the tumor tissue in the area. After the heat exchange is completed The liquid nitrogen is sent out through the return pipeline, and the freezing mode is completed; then the melting mode is turned on, and the alcohol vapor is delivered from the input pipeline. When it reaches the working part of the needle tip, it liquefies and releases heat to melt the ice ball, and the liquefied alcohol also flows through the retu...
