Patent ID: 7056315

Claim:
A liposuction apparatus having a tubular cannula, an injection source for injecting liquid, a suction source, and a hand piece, wherein: the hand piece ( 2 ) is sterile, disposable and delivers at least one jet ( 4 ) of working liquid under pressure; the tubular cannula ( 3 ) being removable from the hand piece ( 2 ) to facilitate resterilization and reuse thereof, the tubular cannula has a first distal extremity ( 18 ) with at least one suction orifice ( 24 ) and at least one ejection orifice ( 23 ) spaced from the at least one suction orifice ( 24 ) for ejecting sterile working liquid under pressure and a second proximate extremity ( 19 ) which facilitates releasable attachment of the tubular cannula ( 3 ) to the hand piece ( 2 ), a side surface of the tubular cannula ( 3 ) comprises an area ( 27 ), extending on an angular sector of about 90°, without any suction orifice; the suction source ( 14 ) communicates via a sterile disposable tube of the hand piece ( 2 ) with the suction orifice ( 24 ) at the first distal extremity ( 18 ); the injection source has a generator which generates pressurized sterile working liquid connected via a sterile disposable tube of the sterile disposable hand piece ( 2 ) with the ejection orifice ( 23 ) of the first distal extremity ( 18 ); a disposable reserve of the sterile working liquid supplies the generator with the working liquid; a device for measuring a quantity of the pressurized sterile working liquid injected and a quantity suctioned; and regulating means for regulating the temperature of the pressurized sterile working liquid so that the temperature of the pressurized sterile working liquid is approximately equal to that of the human body.
