A spatulated cannula generally comprises a planar spatula tip disposed at a distal end of a cannular body. The spatulated cannulae are particularly useful with power assisted liposuction (PAL) instruments, especially rotational poser assisted liposuction equipment. ## Claims ### Claim 1 In a handheld liposuction device having a single cannula, a means for holding and maneuvering the cannula, and a means for driving the cannula in a rotating motion, the improvement comprising: a planar spatulated tip extending outwardly from a body of the cannula. ### Claim 2 (depends on 1) The improvement of claim 1, wherein said spatulated tip comprises a rounded point. ### Claim 3 (depends on 1) The improvement of claim 1, wherein said spatulated tip comprises a width greater than a diameter of the cannular body. ### Claim 4 (depends on 1) The improvement of claim 1, wherein said spatulated tip comprises a width less than a diameter of the cannular body. ### Claim 5 (depends on 1) The improvement of claim 1, comprising a tapered volume extending between the cannular body and the spatulated tip. ### Claim 6 (depends on 1) The improvement of claim 1, wherein said spatulated tip comprises a first spatula portion and a second spatula portion, the first spatula portion having a first planar volume being disposed in a first plane and the second spatula portion having a second planar volume being disposed in a second plane. ### Claim 7 (depends on 6) The improvement of claim 6, wherein the first plane is distinct form the second plane. ### Claim 8 (depends on 6) The improvement of claim 6, wherein the first plane is orthogonal with the second plane. ### Claim 9 (depends on 6) The improvement of claim 6, comprising three or more spatula portions. ### Claim 10 (depends on 1) The improvement of claim 1, wherein the spatulated tip comprises tapered sides leading to a rounded point. ### Claim 11 (depends on 1) The improvement of claim 1 having a coupler disposed at a proximal end of the cannular body, the coupler being configured to engage with a rotational power assisted liposuction device. ### Claim 12 (depends on 1) The improvement of claim 1, comprising one or more apertures disposed about a surface of the cannular body. ### Claim 13 (depends on 12) The improvement of claim 12, wherein said apertures are configured in a pre-determined pattern for optimizing communication of fluids and body materials through an inner cavity of the cannula. ### Claim 14 (depends on 13) The improvement of claim 13, wherein said pre-determined pattern is one of: a Mercedes pattern, or a Christmas tree pattern. ### Claim 15 A spatulated cannula for use with a liposuction device, comprising: a cannular body extending from a proximal end to a distal end; a coupler disposed at the proximal end and configured to engage with a power assisted liposuction device; one or more apertures disposed about a surface of the cannular body; and a planar spatula tip extending outwardly from the cannular body at the distal end thereof; the planar spatula tip being one of: a regular spatula tip; a widened spatula tip; a narrowed spatula tip; an elongated spatula tip; or a multi-portion spatula tip. ### Claim 16 (depends on 15) The spatulated cannula of claim 15, wherein said spatulated tip comprises a first spatula portion and a second spatula portion, the first spatula portion having a first planar volume being disposed in a first plane and the second spatula portion having a second planar volume being disposed in a second plane, wherein the first plane is distinct from the second plane. ### Claim 17 A method for using a handheld liposuction device comprising rotational power assisted motion, comprising: combining a spatulated cannula with the liposuction device; and performing a liposuction procedure. ### Claim 18 (depends on 17) The method of claim 17, wherein said spatulated tip comprises a first spatula portion and a second spatula portion, the first spatula portion having a first planar volume being disposed in a first plane and the second spatula portion having a second planar volume being disposed in a second plane, wherein the first plane is distinct from the second plane.
