The invention relates to a cryotherapy system and a control method thereof, relates to the technical field of cryoablation, and aims to solve the technical problem of nonadjustable cooling rate. The cryotherapy system of the present invention comprises a low-temperature working medium supply unit comprising a first low-temperature working medium storage unit storing in which a first low-temperature working medium is stored and a second low-temperature working medium supply device with a second low-temperature working medium. Since the first low-temperature working medium and the second low-temperature working medium has different heat exchange rates on the inner wall of the treatment instrument, the purpose of adjusting the cooling rate of the target area can be achieved by controlling the low-temperature working media in different phases input into the treatment device, thereby implementing different cooling strategies to different tumor lesions. Therefore, the cryotherapy system of the present invention provides support for formulating more accurate treatment schemes.
Description
technical field [0001] The invention relates to the technical field of cryoablation, in particular to a low-temperature cryotherapy system and a control method thereof. Background technique [0002] In recent years, cryogenic treatment of malignant tumors has become a new treatment modality. The low-temperature cryotherapy equipment used generally uses liquid nitrogen cooling, argon / nitrogen throttling, etc. to cool the frozen end, and then cool the lesion to achieve the purpose of treatment. However, when the low-temperature working medium in the current low-temperature cryoablation equipment reaches the ablation needle through the pipeline and ablates the lesion, under the condition that the heat source around the lesion remains unchanged and the low-temperature working medium is supplied in sufficient quantities, its cooling effect on the tumor site The rate is relatively fixed and cannot be adjusted, which has limitations in the clinical treatment of tumor cryotherapy. ...
