ABSTRACT:
A filter for a laser surgery smoke evacuation system including a generally cylindrical hollow housing with endcaps on either end to hold a plurality of filter elements in place within the housing. The inlet end of the housing includes a hollow cone with a cylindrical inlet projecting from the apex of the cone and a base ring projecting from the base of the cone. The endcaps are held in place by adhesive tape strips with a high friction backing. The high friction backing helps hold the filter lightly in place during use. The filter is disposable and easily removable from the system and includes no mechanical apparatus to hold the filter in the system.
