Medical cooling device and cooling method using the same

A cooling module comprising:

• a cooling medium extending from a proximal end to a distal end in a longitudinal direction, the cooling medium configured to directly contact a target area or directly contact a cooling tip contacting the target area;
• a first cooling generator including a first surface and a second surface,
• the first cooling generator disposed on a first side of the cooling medium, and
• the first cooling generator configured to decrease a temperature of the first surface and increase a temperature of the second surface to cause cooling energy provided from the first surface to one side of the cooling medium when cooling the target area;
• and
• a second cooling generator including a third surface and a fourth surface,
• the second cooling generator disposed a second side of the cooling medium, and
• the second cooling generator configured to decrease a temperature of the third surface and increase a temperature of the fourth surface to cause a cooling energy provided from the third surface to the second side of the cooling medium when cooling the target area,
• wherein the cooling medium has a cooling center located on an extension line,
• wherein the extension line is a virtual line extending in the longitudinal direction of the cooling medium and passing through a center of mass of the cooling medium and the cooling center is a center of thermal conductivity of the cooling medium, and
• wherein a distance from the cooling center to the distal end of the cooling medium is 30 mm or less.
