Each movable sealing port can be rotatable relative to the housing and each sealing element can be rotatable relative to the housing along a predetermined orbital path.

主权项

1. A surgical access device, comprising:
a housing having a working channel extending therethrough; and a base coupled to the housing and having first and second sealing elements, the base being configured to rotate about a central axis thereof relative to the housing, and the first and second sealing elements each being configured to receive an instrument inserted therethrough and into the working channel, and each of the first and second sealing elements being movable relative to one another in a predetermined orbital path, the predetermined orbital path of the first sealing element having a first central axis offset from a second central axis of the predetermined orbital path of the second sealing element, the first and second central axes being offset from the central axis of the base, the first sealing element having a central axis that does not intersect the first central axis, and the second sealing element having a central axis does not intersect the second central axis.
