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 cryoprobe with a guide wire guiding device and a method of use. Background technique [0002] At present, the existing cryo-knife uses a cryo-knife head to extend into the body, especially when it passes through a curved channel in the human body, such as the biliary tract or intestine. Difficult, the operation is very laborious. Summary 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 with reasonable design, compact structure and convenient use and a method of use. [0004] In order to solve the above problems, the technical solution adopted by the present invention is: [0005] A hose cryoprobe with a guide wire guide device, comprising a refrigerant return air and a guide wire channel tube extending into the human body at the right part, and a cold head arranged at the right end of the refrigerant return air and guide wire cha...
