Patent ID: 6902559

Claim:
A liposuction device for removing subcutaneous fat ( 12 ) comprising a cannula ( 16 ) having a suction opening ( 22 ) for sucking therethrough subcutaneous fat ( 12 ), an injection line ( 18 ) for delivering a working fluid to an injection opening ( 20 ) of the cannula ( 16 ), the injection opening ( 20 ) being constructed and arranged at a front end of the injection line ( 18 ) and having a slit-shaped configuration whereby the working fluid exits the injection opening ( 20 ) forwardly of the front end in the shape of a working fluid fan ( 21 ), the width of the slit-shaped injection opening ( 20 ) being smaller than 1.0 mm, the slit-shaped injection opening ( 20 ) being inclined to a longitudinal axis ( 23 ) of the injection line ( 18 ) at an angle (α) thereto ranging substantially between 3 to 45° so that the working fluid fan ( 21 ) exits at said angle (α) with respect to the longitudinal axis ( 23 ), and the slit-shaped injection opening ( 20 ) being the only opening located at the front end of the injection line.
