ABSTRACT:
Flexible button cannulas for arthroscopic surgery made from silicone, or a similar flexible material. Exemplary embodiments of the button cannula have large inner and outer flanges for improved stability when installed into the body. Exemplary embodiments of the button cannula include two fluid dams. A first dam is located within the cannula elongated portal between the inner and outer flanges and prevents fluid from squirting out of the body when instruments are being inserted through the cannula. A second dam is located at the outer, or top, flange (i.e., the flange that remains outside of the body) to prevent fluid from squirting when the cannula itself is being inserted within the body. Exemplary embodiments of the button cannula also include an outer, or top, flange that is thicker than the inner, or bottom, flange, to prevent the over insertion of the cannula into the body.
