Cryotherapy system

The invention discloses a cryotherapy system, and belongs to the technical field of medical equipment. Comprising a low-temperature cryotherapy machine and a low-temperature cryotherapy probe, the low-temperature cryotherapy machine is provided with a visual recognition module, an artificial intelligence processing unit, a control unit and a human-computer interaction interface, judges diseases based on visual recognition and artificial intelligence, is used in cooperation with the low-temperature cryotherapy probe, and can achieve accurate temperature control and improve the treatment efficiency. The low-temperature cryotherapy probe comprises a handle, a heating device, a temperature measuring device and a freezing probe, the Joule-Thomson principle is utilized, namely when high-pressure gas passes through a section with a suddenly-reduced section, due to the phenomena that the pressure of the gas can be reduced and the temperature can be changed, cold source gas is cooled, and diseases are treated through
