A surgical cannula assembly includes a cannula, an adapter ring, and a housing. The adapter ring is defined at the proximal end portion of the cannula and includes a first sealing surface. The housing includes a port structure for engagement with the adapter ring. The port has a lip with a second sealing surface adapted to engage the first sealing surface. The first and second sealing surfaces are preferably annular surfaces which are non-parallel with respect to each other.

[ What is claimed is:] [1.] A surgical cannula assembly which comprises:a) a cannula defining a longitudinal axis and having a free distal end and a proximal end portion;b) an adapter ring defined at the proximal end portion of the cannula, the adapter ring having a first sealing surface oriented at a first angle relative to the longitudinal axis; andc) a housing having a port structure for sealing engagement with the adapter ring, the port structure including a second sealing surface for sealing contact with the first sealing surface, the second sealing surface being oriented at a second angle from the longitudinal axis, the second angle differing from the first angle by from about 3.degree. to about 10.degree..
