    摘要: In a cryotherapy apparatus 1, an FPSC2 (free piston type Stirling cooling machine) is used that is driven by a normal power supply, and that is comparatively small and inexpensive. In addition, to a heat absorbing portion 2a of the FPSC2 connected is a base end 6a of an inner pipe 6 in which a refrigerant that operates at a low temperature is encapsulated. As a result of this, when the FPSC2 is driven in a state where a heat exchanging portion 8 provided at a tip 6b of the inner pipe 6 is located on a predetermined site inside a body, heat moves from the heat exchanging portion 8 to the heat absorbing portion 2a of the FPSC2 through the refrigerant. At this time, the refrigerant encapsulated in the inner pipe 6 is insulated from the outside since a vacuumed gap S is formed by the inner pipe 6 being covered with an outer pipe 7. As a result of this, an ice ball is formed on the predetermined site where the heat exchanging portion 8 has been located.
