Abstract:
1. A closed loop fat transplantation system comprising: a fat transplantation receptacle (hereinafter referred as FT receptacle), wherein the FT receptacle includes a vertical hem portion which can join an individual syringe needle or a cannula selectively, a cylinder-shaped receptacle to aspirate and store a predetermined amount of fat, a piston head that is inserted to divide the cylinder-shaped receptacle into a front fat storing space and a rear pressurization and decompression space; and an exterior mechanical pressurization and decompression means, wherein the pressurization and decompression means can apply positive/negative pressure to the rear pressurization and decompression space and has a structure separable from the FT receptacle, and wherein the mechanical pressurization and decompression means is a rear stopple to keep airtight the rear pressurization and decompression space of the FT receptacle, wherein a connecting jack is formed on the rear stopple to connect an external tube and then to connect an external suction unit or an air pressure unit, whereby applying positive/negative pressure to the rear pressurization and decompression space by replacing the external suction unit or the air pressure unit, whereby fat transplantation can be performed without receptacle exchange using the same FT receptacle by extracting fat from a portion of a patient's body by applying negative pressure to the rear pressurization and decompression space, and transplanting fat to the other portion of the patient's body by applying positive pressure to the rear pressurization and decompression space, wherein the closed loop fat transplantation system further comprises a front stopple; and a locking pin; and two penetration pipes, wherein the front stopple is joined with the vertical hem portion of the FT receptacle to replace the syringe or the cannula, wherein the locking pin fixes the piston head on a rear tip of the FT receptacle, wherein the two penetration pipes have a pressure interception valve individually, which are formed on the piston head, wherein one of the penetration pipe is connected to the cannula, wherein the other one of the penetration pipe is connected to the external suction unit; wherein when the locking pin is fixed and negative pressure is applied, fat is extracted; wherein when the cannula and the suction unit are separated from the FT receptacle and the locking pin is removed, the pressure interception valves close the penetration pipes to keep the fat storing space airtight; wherein when the locking pin is removed and the valves close the penetration pipes, the rear stopple is attached to the FT receptacle to keep the rear pressurization and decompression space of the FT receptacle airtight, wherein the connecting jack is formed on the rear stopple to connect an external tube so that the connecting jack is connected to an external air pressure unit; wherein when the syringe needle is attached to the vertical hem portion of the FT receptacle, fat transplantation is performed through the syringe needle by applying air pressure to the rear space of the piston head.
