Method and apparatus for performing liposuction
First Claim
1. Apparatus for use in liposuction treatment, which comprises:
- a hand-holdable housing having a first cavity;
a cannula having a distal end and a proximal end, and at least one suction aperture about said distal end and a base operably associated with said proximal end, said cannula being insertable within said first cavity so that said cannula is free to reciprocate relative to said housing; and
reciprocation means disposed within said housing and operable associated with said cannula so that said cannula can be selectively caused to reciprocate relative to said hand-holdable housing within said first cavity.

Abstract
A method and apparatus is disclosed for mechanically-assisted liposuction treatment. The apparatus includes a hand-holdable housing, a cannula, and a reciprocation mechanism. The hand-holdable housing has a cavity adaptable for receipt of a portion of the cannula. The cannula has a distal end and a proximal end and at least one suction aperture about the distal end. The cannula also has a base portion which is operably associated with the proximal end and insertable within the cavity so that the cannula is free to reciprocate relative to the housing. The reciprocation mechanism is disposed within the housing and is operably associated with the cannula so that the cannula can be selectively caused to reciprocate relative to the housing. The cannula is releasably detachable from the hand-holdable housing to facilitate cleaning and sterilization of the cannula and the housing.

34. A cannula for releasable insertion into a cannula cavity formed in a hand-holdable housing of a powered liposuction device having reciprocation means for reciprocating said cannula relative to said hand-holdable housing, said cannula comprising:
-
an elongated tube having a distal end and a proximal end, and at least one suction aperture about said distal end; a base operably associated with said proximal end of said elongated tube and facilitating sliding movement of said cannula within said cannula cavity, said base further including an outlet port and a continuous passageway extending from said suction aperture to said outlet port; and at least one notch means formed in said base for operably associating said reciprocation means with said base when said cannula is inserted into said cannula cavity. - View Dependent Claims (35, 36, 37)
