A suction device for aspiration of intra-abdominal fluid and debris comprising a negative pressure source (not shown), a suction tube 13, a chamber 10 containing a rotating loop shaped blade 9 which is rotated by an engine (not shown), and an outlet tube 12, wherein in use aspirated viscous fluid is sucked through the suction tube 13 into the chamber 10 and the fluid is broken down by the rotating blade 9, before exiting the outlet 12. A lever 8 is used to adjust the suction pressure by compressing spring 6 which covers or uncovers slot 7. The device allows the aspiration to be liquefied proximal from the distal end without the risk of damaging tissue. |
