PURPOSE: A fat disassembly apparatus with a superior disassembly effect of fat tissue is provided to make active blood purification and circulation by performing fat tissue dissembling operation using vacuum suction and thermoelectric method, thereby smoothly emitting waste and toxin in blood to the outside of a human body. CONSTITUTION: A probe has a socket shape including an empty space in inside. An RF thermoelectric electrode(140) is respectively installed in inner walls of both sides facing with the probe and generates an RF high frequency wave responding to an RF signal. The RF thermoelectric electrode includes a cooling means. A vacuum suction part(160) is communicated with a ceiling inside of a probe and absorbs a target area in order to contact to the RF thermoelectric electrode using vacuum pressure. The RF high frequency is applied to the target area absorbed to inside of the probe by the vacuum suction part in order to dissemble fat tissue(30) in the target area and perform cooling of the same area.
