Abstract

The invention relates to a hose cryoprobe with a guide wire guiding device and a usage method. The hose cryoprobe comprises a refrigerant return air and guide wire channel tube with the right portion extending into a human body and a cold head arranged at the right end of the refrigerant return air and guide wire channel tube, wherein a guide wire for guiding the cold head to pass through an inner bent channel of the human body, an in-channel blocking tumor and / or an in-channel blocking lesion tissue to reach a diseased part. The hose cryoprobe has the advantages of being capable of achieving repeated treatment, making a patient have no pain, being low in cost, simple in operation and same in treatment effect and bringing few complications.

Description

technical field [0001] The invention relates to a hose freezing probe with a guide wire guiding device and a method for using it. Background technique [0002] At present, the existing cryo-knife all use a cryo-knife head to extend into the body, especially when it passes through the curved passages in the human body such as the biliary tract or intestinal tract, blocking the tumor and / or blocking the diseased tissue in the passage to reach the lesion. Difficult, the operation is very laborious. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a hose cryoprobe with a guide wire guiding device and a use method with reasonable design, compact structure and convenient use. [0004] In order to solve the problems referred to above, the technical scheme that the present invention takes is: [0005] A hose freezing probe with a guide wire guiding device, comprising a refrigerant return air and guide wire passage pipe ...
