Abstract
A high and low temperature composite ablation surgery system, relating to the technical field of cryotherapy, used to improve the safety and effectiveness of therapy, and comprising a main unit (100) and a cryogenic-thermal ablation probe (200) connected to the main unit (100). The main unit (100) comprises a cold working medium supply system (300), a hot working medium supply system (400), and a working medium distribution system (500). The working medium distribution system (500) can respectively control the cold working medium supply system (300) to deliver a cold working medium to the cryogenic-thermal ablation probe (200) and control the hot working medium supply system (400) to deliver a hot working medium to the cryogenic-thermal ablation probe (200). Therefore, after low-temperature therapy is completed, a therapy area can be quickly rewarmed, thereby providing a basis for improving the safety, economy and convenience of the surgery.
