Control system and cryoablation system

The invention provides a control system and a cryoablation system, and the system comprises a pressure control module which is used for obtaining the pressure value of the inner cavity pressure of a balloon of a balloon catheter in real time, comparing the pressure value obtained in real time with the target pressure, and adjusting the cryogenic dose in the balloon according to the comparison result, the pressure of the inner cavity of the balloon is consistent with the target pressure. Therefore, the internal pressure of the balloon in the ablation process can be kept stable through the pressure control logic, balloon size fluctuation caused by balloon internal pressure fluctuation is avoided, the shape of the balloon is stable in the treatment process, and the balloon is prevented from deviating from a target site. 本发明提供一种控制系统及冷冻消融系统，包括：压力控制模块，用于实时获取球囊导管的球囊的内腔压力的压力值，并比较实时获取的所述压力值与目标压力的大小，以及根据比较结果调整所述球囊内的冷冻剂量的大小，以使得所述球囊的内腔压力与所述目标压力一致。如此，便可通过压力控制逻辑使得球囊在消融过程中内压保持稳定，避免球囊内压波动引起球囊大小波动，使治疗过程中球囊形态稳定，防止球囊偏离目标位点。
