ABSTRACT:
A seal assembly for permitting hand assisted laparoscopic procedures is disclosed. The seal assembly includes a seal cap having a seal positioned within a housing. The housing includes a lower seal ring having a track which supports an upper seal ring for relative rotational motion. The seal is supported between the upper seal ring and the lower seal ring for rotation between an open orientation and a closed orientation. A ratchet mechanism is provided for controlling motion of the upper seal ring relative to the lower seal ring. The ratchet mechanism includes a deflection feature and a series of gear teeth, wherein the series of gear teeth are oriented to engage the deflection feature.
