Abstract
A surgical suction wand comprising a generally tubular body with a hollow tip at one end thereof, a cap releasably closing the other end of the tubular body, and a filter member within the body and joinable to the under surface of the cap. The hollow tip communicates with the interior of the body. A tubular connector is mounted externally on the cap and communicates with the interior of the cap and the body. The filter member within the body defines a first chamber between the filter member and the body and a second chamber within the filter member which communicates with the tubular connector through the cap. One or more apertures through the filter member permit limited communication between the first and second chambers. The cap has positioning means therein for locating and securing one end of the filter member within the cap and body. The other end of the filter member is closed and disposed in the body adjacent to the hollow tip. In operation, waste material flows through the tip into the hollow interior of the body wherein particulate waste is trapped in the first chamber by the filter member while fluids pass through the apertures in the filter member and out of the suction wand via the tubular connector at the cap. The filter member is easily removed (along with the cap), cleaned and returned to the interior of the tubular body as required.
