Embodiment Construction

[0067] Embodiments of the present invention will be described below with reference to the drawings.

[0068] refer to figure 1 and figure 2 The needle probe for cooling operation described in the first example of this embodiment will be described.

[0069] exist figure 1 The needle probe 10 for cooling operation described in the first example of the present embodiment, whose schematic structure is illustrated in FIG. 2 , has a first cylindrical body 14 and a second cylindrical body 12 .

[0070] The first cylindrical body 14 and the second cylindrical body 12 are made of different kinds of thin metals, and are extended while being electrically insulated from each other.

[0071] The first cylindrical body 14 and the second cylindrical body 12 have the basic function of the detector that can make the refrigerant circulate, and also have the function of the compensating wire (core wire) of the thermocouple. As long as this function is played, it can be used. metal material....

Abstract

Provided are a needle probe for cooling operation and a cooling operation system, in which a very small area can be precisely cooled. A needle probe (10) for cooling operation includes a first cylindrical body (14) and a second cylindrical body (12) made of thin metals of different kinds and extending in a state of being electrically insulated from each other. The first cylindrical body (14) and second cylindrical body (12) serve as channels for refrigerant as well as compensation conduction wires for a thermocouple. One end of each of the first cylindrical body (14) and second cylindrical body (12) is closed and bonded to form a tip end portion (18). The tip end portion (18) serves as a temperature measurement contact of a thermocouple. A very small interconnection portion (20) for interconnecting the inside and outside of the first cylindrical body (14) is formed near the tip end portion (18). Refrigerant is introduced into the first cylindrical body (14), and when the refrigerant is passed through the very small interconnection portion (20) and introduced to the second tubular body (12), the refrigerant evaporates or adiabatically expands, whereby cold heat usable for cooling the tip end portion (18) is generated. The tip end portion (18) is applied to a target area to be treated, thereby cooling the target area.

Description

technical field [0001] The present invention relates to a needle probe for cooling operation and a cooling operation system. Background technique [0002] Cryosurgery (cryogenic operation) in which an affected part is frozen is widely performed. [0003] Cryosurgery is a surgery that destroys the organelles in the cells and necrosis in the process of thawing the cells after freezing them. Since there are fewer pains and postoperative scars (denaturation) during the operation, and there are fewer postoperative complications, Furthermore, the operation cost can be reduced, so it is considered to be suitable. Cryosurgery can be broadly classified into two types depending on the affected area to be operated on. [0004] One of them is used to treat an affected part such as a cancer or a tumor in the stomach. In this case, for example, a probe for freezing is inserted into the affected part in the body through an opening to freeze the affected part. [0005] Cryosurgery, which...
