Abstract
An assembly structured to selectively orient a seal between an open position and a closed position. The assembly includes an expander structure disposable into a seal open or a seal closed orientation by being rotated or otherwise movable into and out of forced engagement with predetermined portions of the seal structure. The seal open orientation disposes the seal structure out of engagement with an instrument passing there through and may also facilitate a rapid venting of insufflation gas from an inflated body cavity, such as when the seal positioning assembly is used with a trocar assembly involved in the performance of laprascopic or like surgery. A biasing assembly may be connected to the seal structure to bias it in a normally closed position in the absence of an instrument disposed within the seal structure.
