the present invention is accumulated in the body using a vacuum pressure generated by a vacuum suction relates to a vacuum suction device to remove by suction of fat, the outer tube and the inlet hole formed in the longitudinal direction on the upper outer circumference, is inserted into the inside of the outer tube is reciprocated forward and backward together with the movement of the mobile piston and the suction in the top peripheral The ball is formed that includes a cannula to suction the fat inner tube Is connected to the lower end of the outer pipe, the connection pipe moving space formed therein Is connected to the lower end of the inner tube, a piston moving in reciprocating motion inside the connector Said mobile bottom and being connected to the piston, the suction of the inner tube and communicating with the inside is formed, and out to the withdrawal mouth is the operation rod of the operating member Is connected to the lower end of the connection pipe, the reciprocating movement of the operating member to the operation rod And is connected to the lower end of the operating rod, and formed to communicate with the suction, the bottom of the discharge pipe for discharging the sucked fat is connected to the suction hose of the vacuum sucker provides automated liposuction device containing <. br /> According to the present invention, the cannula can be made of a double tube to automatically reciprocate around an inner tube of the cannula by the operation member, and a manual shake or vibration than a vibration-type write underwent liposuction for the correct treatment area, surrounding body tissue damage and cell death caused by skin friction does not occur, the operation is easier and the procedure is significantly reduced fatigue of the operator, and also reduce operation time, it is possible to always draw a predetermined treatment result reduces the deviation, It maintained smooth without jagged the treated area after the operation, the surgical side ef
