摘要:
A seal assembly for permitting hand assisted laparoscopic procedures 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 and wherein the seal is supported between the upper seal ring and the lower seal ring for rotation between an open orientation and a closed orientation. The track includes an inner upstanding annular wall and an outer upstanding annular wall connected by a base member. A ratchet mechanism controls motion of the upper seal ring relative to the lower seal ring. The ratchet mechanism includes a ratchet arm oriented to engage a ratchet surface and the ratchet surface is positioned between the inner upstanding annular wall and the outer upstanding annular wall.
