The present invention relates to an ultrasonic stent coating system. The purpose of the present invention is to provide an ultrasonic stent coating system which is capable of constantly coating the coating solution on a stent by accurately spraying a coating solution comprising chemicals in a predetermined direction using ultrasonic waves and air. An ultrasonic stent coating system according to the present invention includes a stent transfer unit which transfers a position of the stent in a state that a stent is fixed, a stent coating unit which sprays a coating solution and generates ultrasonic waves to coat the surface of the stent with the coating solution, and a case part. The stent transfer unit includes a stent fixing part to one end of which the stent is fixed, a rotation power generating part which generates a rotation power, a power transmission part which transmits a rotation power to the stent fixing part to rotate the stent by connecting the rotation power generating part to the other end of the stent fixing part, a joint part which is disposed under the rotation power generating part to maintain a position of the rotation power generating part, and an LM (Linear Motion) driving part on which the joint part is mounted to linearly move the position of the rotation power generating part. The stent fixing part, the rotation power generating part, and the power transmission part are housed in the case part, and an opening part is formed in one side the case part such that the stent fixing part having the stent fixed thereto is protruded to the outside through the opening part by linear movements of the LM driving part.COPYRIGHT KIPO 2016본 발명은 초음파 스텐트 코팅 시스템에 관한 것으로, 스텐트를 고정하여 위치를 이동시키는 스텐트 이송장치와, 코팅액을 분사하고 초음파를 발생하여 상기 스텐트의 표면을 코팅하는 스텐트 코팅장치 및 케이스부를 포함하고, 상기 스텐트 이송장치는, 일단에 상기 스텐트를 고정하는 스텐트 고정부와, 회전 동력을 발생하는 회전 동력 발생부와, 상기 스텐트 고정부의 타단과 상기 회전 동력 발생부를 연결하여, 상기 스텐트를 회전시키도록 회전 동력을 상기 스텐트 고정부에 전달하는 동력 전달부와, 상기 회전 동력 발생부의 하부에 배치되어, 상기 회전 동력 발생부의 위치를 유지하는 조인트부 및 상기
