    Abstract: Provided are a method for adjusting an in-tank pressure of a working medium storage tank and an apparatus for the same. The method includes: acquiring a backflow temperature collected by each of first thermocouples; counting the number of target backflow paths whose backflow temperature reaches a preset temperature; and adjusting an in-tank pressure of the working medium storage tank to a target in-tank pressure corresponding to the number of the target backflow paths according to the number of the target backflow paths and a corresponding relationship between a preset number of backflow paths and the in-tank pressure. The control box determines the target in-tank pressure corresponding to the number of the target backflow paths to realize automatic adjustment of the in-tank pressure of the working medium storage tank.

    Abstract: Disclosed is an electrical control system for minimally invasive tumor therapies. The electrical control system for minimally invasive tumor therapies includes a control module, a perfusion module and a power box. The perfusion module includes a working medium storage tank, a tank liquid level meter, a tank pressure sensor, a tank deflation valve, a liquid charging valve and an external working medium container. The power box is configured to supply power to the control module and the perfusion module. The control module is configured to receive working medium parameters sent by the tank liquid level meter and the tank pressure sensor, and to control, when the work medium parameters meet a perfusion condition, the tank deflation valve and the liquid charging valve to open or close respectively so as to input working medium from the external working medium container into the working medium storage tank.

    Abstract: The present disclosure relates to an ablation device, which relates to the technical field of cryoablation treatments, and is used for solving the technical problem of an excessive burden on an operator caused by the volume of a delivery device being too large. The ablation device of the disclosure comprises an ablation needle and a working medium transmission device connected to the ablation needle. The working medium transmission device comprises a first delivery tube and a second delivery tube. The first delivery tube and the second delivery tube are configured to be of split structures that are independent of each other, such that the structure of the working medium delivery device at the rear end of the ablation needle is smaller and lighter, and thus the burden on the operator's operation can be reduced, making the operation to be more flexible and convenient.

    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.
