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 () and a cryogenic-thermal ablation probe () connected to the main unit (). The main unit () comprises a cold working medium supply system (), a hot working medium supply system (), and a working medium distribution system (). The working medium distribution system () can respectively control the cold working medium supply system () to deliver a cold working medium to the cryogenic-thermal ablation probe () and control the hot working medium supply system () to deliver a hot working medium to the cryogenic-thermal ablation probe (). 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.
