Abstract
A surgical seal assembly includes a sleeve housing adapted to be operatively connected to a surgical sleeve, a seal housing adapted for releasable mounting to the sleeve housing and having a seal member with inner portions adapted to permit passage of a surgical object in substantial sealed relation therewith, and a manual lock member associated with the sleeve housing. The manual lock member is adapted for movement relative to the seal housing between a first position corresponding to a release position of the seal housing to permit removal of the seal housing from mounting to the sleeve housing and a second position corresponding to a lock position of the seal housing to secure the seal housing to the sleeve housing. The manual lock member is preferably adapted for rotational movement relative to a longitudinal axis of the seal housing to move between the first and second positions thereof.
