Abstract

A seal assembly (10) for permitting hand (38) assisted laparoscopic procedures includes a seal cap (14) having an iris seal (12) positioned within a housing (16). The housing includes a lower seal ring (28) having a track (40) which supports an upper seal ring (42) for relative rotational motion, wherein the iris seal is supported between the upper seal ring and the lower seal ring for rotation between an open orientation and a closed orientation. The seal assembly also includes a retractor (18) extending from the seal cap, a spring (72) biasing the upper seal ring relative to the lower seal ring, and a ratchet mechanism (74) controlling motion of the upper seal ring relative to the lower seal ring.
