Abstract:
A liposuction device, comprising:a) sucking cannula means for sucking subcutaneous fat through an entry aperture, the sucking cannula means having defined therein said entry aperture and having a longitudinal axis; b) mechanical drive means for producing and transmitting a movement to the sucking cannula means and on which the sucking cannula means is mounted, the mechanical drive means having an entry for connecting an energy source thereto, and the movement of the sucking cannula means being a nutational movement which has a frequency ranging from 10 to 500 Hz and which comprises a vibrational component and a translational component, the vibrational component being perpendicular to the longitudinal axis of the sucking cannula means and the translational component being in line with the longitudinal axis of the sucking cannula means and having an amplitude ranging from 2 mm up to but less than 1 cm; c) a housing for housing the mechanical drive means; and d) a free space provided between the sucking cannula means and the housing, the free space being dimensioned in such a manner to allow the vibrational component of the nutational movement to dislocate subcutaneous fat in use.
