Extracorporeal circulation heart cooling device

The utility model provides an extracorporeal circulation heart cooling device, and relates to the technical field of cardiac surgery extracorporeal refrigeration. Comprising a hollow wrapping body and a refrigeration part, a circulating heat conduction assembly is embedded in the wrapping body, a part of the circulating heat conduction assembly is arranged in the refrigeration part, and the device further comprises a detection assembly used for detecting the temperature of the circulating heat conduction assembly. The circulating heat conduction assembly is embedded in the wrapping body, heat transmitted to the wrapping body by the heart can be guided, and part of the circulating heat conduction assembly is arranged in the refrigeration component to achieve circulating refrigeration, so that the wrapping body is kept at a relatively constant low temperature, and the cooling effect at the heart is guaranteed; the arranged detection assembly can ensure that the equipment can effectively monitor the heart refrig
