摘要： To provide a cooling needle probe and cooling system which can accurately cool a minute region. A cooling needle probe 10 includes a first cylindrical body 14 and second cylindrical body 12 which are made of thin-walled dissimilar metals and run longitudinally by being electrically insulated from each other. The first cylindrical body 14 and second cylindrical body 12 serve both as a flow path for a refrigerant and compensating leads of a thermocouple. The first cylindrical body 14 and second cylindrical body 12 are closed and joined at one end, forming a distal part 18, which also serves as a measuring junction of a thermocouple of a thermocouple. A minute communicating section 20 is formed near the distal part 18 to communicate between interior and exterior of the first cylindrical body 14. The refrigerant is introduced into the first cylindrical body 14 and lead out into the second cylindrical body 12 through the minute communicating section 20 so as to evaporate or adiabatically expand upon entry into the second cylindrical body 12, producing cold and thereby cooling the distal part 18. The distal part 18 is applied to a surgical region to cool the surgical region.
