Abstract
An elongated arthroscopic cannula having proximal and distal elastomeric sealing means through which elongated surgical instruments may be inserted. The cannula seals maintain their effectiveness with and without instruments present within the cannula. The distal sealing means is a transverse linear slit supported around its perimeter by a racetrack-shaped reinforcing member to engage instruments inserted therethrough and to seal the proximal side of the linear slit from the distal side when no instrument is used. The proximal sealing means is a floating, circular aperture capable of being laterally moved and tilted in order to provide a sealing function around an instrument shaft whether or not the shaft is aligned with the axis of the cannula.
