ABSTRACT:
A surgical smoke evacuator includes a housing and means defining an air flow channel through the housing. At least one filter having a longitudinal axis is disposed in the air flow channel with portions of the housing defining an inlet for receiving the filter and a filter cavity for receiving the filter in the air flow channel. Tabs on the filter and associated guide slots on the housing, guide the filter along a circuitous path between the inlet and filter cavity during loading and unloading of the filter. This path includes axial portions which facilitate axial filter movement and angular portions which facilitate angular filter movement relative to the housing.
