Claims68
A smoke removal apparatus comprising:
- a housing;
- inlet means for defining an inlet pathway for impure gas from a surgical cavity to said housing, wherein said inlet means comprise Luer locks for connecting said surgical cavity to said inlet pathway;
- filter means for filtering impurities from impure gas to form filtered gas;
- outlet means for defining an outlet pathway for said filtered gas from said housing to said surgical cavity;
- and
- a fan, for drawing impure gas from said surgical cavity, through said inlet means, and through said filter means to form said filtered gas and for driving said filtered gas through said outlet means into said surgical cavity, wherein said outlet means are adapted to laparoscopic surgical instrument assembly, wherein said filter means comprises a pre-filter and a primary filter with said pre-filter being positioned between said fan and said primary filter.
