There is disclosed a skin seal (10) and anchoring cannula (12) for use in surgery. The skin seal (10) generally includes a distally extending flexible or compressable member (22) and a latch assembly (20) to secure the skin seal (10) about a shaft (26) of the cannula. Preferably the latch assembly (20) is of an over the center clamp or lock design. The disclosed cannula is preferably a balloon tip cannula having an inflation port (34) and a lumen (66) communicating within the interior of the balloon (32) so as to inflate the balloon (32). There is also a method of securing a cannula to tissue, preferably an abdominal wall, utilizing the disclosed balloon tip cannula and skin seal.
