| description | Disclosed is a multichannel cryoablation system, which employs a high-pressure nitrogen as a gas source. The system includes a main gas pipeline, a rewarming pipeline, a refrigeration high-pressure pipeline, a refrigeration low-pressure pipeline, and N channel pipelines. The main gas pipeline is provided with a gas source input port, the rewarming pipeline is communicated with the main gas pipeline, and the rewarming pipeline is divided into N rewarming branch channels. The refrigeration high-pressure pipeline is communicated with the main gas pipeline, and the refrigeration low-pressure pipeline is communicated with the main gas pipeline, and the refrigeration low-pressure pipeline shares a section of gas supply path with a rear section of the refrigeration high-pressure pipeline, the gas supply path being communicated with N refrigeration branch channels. Each of N channel pipelines has one end used to be connected with an ablation needle, and the other end used to be connected with one of the refrigeration branch channels and/or one of the rewarming branch channels, wherein N is a positive integer greater than or equal to 2. |
