SURGICAL PORTAL APPARATUS WITH WAFFLE SEAL A surgical portal apparatus (100) includes a portal housing (202), an elongated portal member (204) connected to the portal housing (202) and depending therefrom, and 5 a seal member (306) comprising a resilient material and being mounted to the portal housing (202). The portal housing (202) and the portal member (204) have an axial bore for reception and passage of a surgical object. The seal member (306) includes leading and trailing faces (318, 320) and has inner portions defining a passage (324) to permit passage (324) of a surgical object. One of the leading and trailing faces (318, 320) io defines a plurality of recessed cells (330) formed within interconnected struts (328). The interconnected struts (328) are relatively flexible to flex upon radial offset manipulation of the object to permit corresponding movement of the passage (324) while substantially maintaining a seal about the surgical object. At least some of the recessed cells (330) define a generally rectangular arrangement. Preferably, the leading end face (318) of the is seal member (306) has the recessed cells (330). |
