that it has a tip 4 port 6 and an internal pressure relief tube 12 connected to tube 18 the same tube 2 used in device 10 can be used in device 30 resulting in a slightly longer overall length for the device fig3 shows a cross section of the handle motor unit 2 of device 10 the handle of handle motor unit 28 is part of the outer housing of motor 38 moving parts 40 of motor 38 are joined to flexible grippers 8 which grip tube body 2 and impart the motion of motor 38 to said tube body 2 in this case the motor is controlled to impart a clockwise and counter clockwise motion of approximately 30 degrees to the tube body 2 also seen in this figure is a terminal end 34 of a tube body 2 with projections 36 to secure tube 22 see fig3 to the tube body 2 fig4 is an enlarged cross sectional view of the distal or tip end of the liposuction cannula here is shown how the pressure relief tube 12 terminates near the tip 4 of tube body 2 fig5 is also an enlarged view of the tip end 4 of tube body 2 of device 10 in this view the tube 2 has been rotated 90 degrees so that the unique shape of the opening 6 can be shown the opening or port is herein described as cusped and is given the reference numeral.
