The present invention relates to a medical skin wrinkle improving device using an RRSS irradiating method of a laser, which is capable of improving skin wrinkles and minimizing tissue damage. The medical skin wrinkle improving device comprises a main body, a handpiece, and a tablet computer. The main body includes: a mounting groove, from which the tablet computer is detached, in an upper part； a signal transmitting and receiving unit which is connected to the tablet computer and transmits and receives signals； and a MICOM which controls laser output. The handpiece includes: a laser oscillating unit which generates the laser irradiated for skin treatment； an optical unit which irradiates the laser generated in the laser oscillating unit with balanced light； a laser scanner which controls irradiating positions of the laser received in the optical unit； and a laser pattern unit in which a movement coordinate value is set so that a moving direction of the laser, which is transmitted in a surgery area outer boundary line called through a surgery area display, is performed in a regular pattern type. The tablet computer includes functions of data input and screen display by a touch screen method and remotely controls the main body through transmitting and receiving of bidirectional signals. The MICOM reduces PIH and D.T. by securing cooling time for a position to which a laser beam is transmitted in a skin surgery step of irradiating the laser beam to skins through time & maximum space cooling by using a peak value of a laser pulse when an amplitude of the generated laser pulse reaches a peak value and then reaches a predetermined normal state value. The MICOM prevents a local burn by not repeatedly irradiating the laser beam to a specific position.COPYRIGHT KIPO 2020본 발명은 피부주름 개선 및 조직 손상을 최소화 하기 위한 레이저의 RRSS 조사방식을 활용한 의료용 피부주름 개선장치에 관한 것으로서,상부에는 태블릿 컴퓨터가 탈부착되는 거치홈이 형성되고, 태블릿 컴퓨터와 연계되어 신호를 주고 받는 신호송수신부와 레이저 출력을 제어하는 마이컴가 내장된 본체； 피부 치료를 위해 조사할 레이저를 생성하는 레이저 발진부와, 상기 레이저
