The present invention relates to a hand piece for an obesity treatment apparatus in which a cooling plate and a housing are integrated with each other, subcutaneous fat suctioned into a treatment space is omnidirectionally cooled, and thus obesity treatment efficiency can be improved to a significant extent. The device according to the present invention includes: a suction and cooling cup having an open surface, having the inner treatment space for treatment part suctioning, connected to a suction conduit, and omnidirectionally cooling the treatment space once cold air is transferred a hand piece body coupled with the suction and cooling cup and a cooling device built into the hand piece body and cooling the entire suction and cooling cup. When the cold air is transferred from the cooling device to the suction and cooling cup, the treatment part suctioned into the treatment space is omnidirectionally cooled and treated. The hand piece for an obesity treatment apparatus using cooling according to the present invention has a structure in which cooling and suction functions are integrated with each other, and thus requires no additional suction housing. In addition, the hand piece for an obesity treatment apparatus using cooling according to the present invention has a removable structure, and thus various types of suction and cooling cups prepared in advance can be selectively used depending on patient states and treatment parts and treatment effects can be improved to a significant extent.COPYRIGHT KIPO 2016본 발명은 냉각판과 하우징을 일체형으로 하여 치료공간으로 흡인(吸引)된 피하지방을 전방향에서 냉각시켜 비만 치료효율을 크게 향상시킨 비만치료 장치용 핸드피스에 관한 것이다. 본 발명의 장치는 개방면이 형성되어 있고 내부에 치료부위를 흡인하기 위한 치료공간이 형성되며, 석션 관로와 연결됨과 아울러 냉기가 전달되면 상기 치료공간을 전방향에서 냉각시키는 석션 및 냉각 컵 상기 석션 및 냉각 컵과 결합되는 핸드피스 몸체 및 상기 핸드피스 몸체에 내장되며 상기 석션 및 냉각 컵을 전체적으로 냉각시키는 냉각장치를 포함하여, 상기 냉각장치로부터 상기 석션 및 냉각 컵의 전체로 냉기가 전달되어 치료공간에 흡인된 치료부위를 전방향에서 냉각 치료하도록 된 것이다. 본 발명의 냉각을 이용한 비만치료장치의 핸드피스는 냉각 기능과 석션 기능이 통합된 일체형 구조로서 별도의 흡입 하우징이 필요없고, 핸드피스와 착탈 구조이므로 치료부위나 환자의 상태에
