  • Publication number: 20230012095
    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.
