Claim 7:
8. A surgical insertion device comprising:
(a) a base ring defining a base ring opening, the base ring coupled to a standard sealable sleeve device positioned through an incision of a patient to fluidically seal an insufflated body cavity of the patient;
(b) a first top ring defining a first top ring opening, the first top ring configured to be operably coupled to the base ring;

(ii) a second seal element positioned adjacent to the first seal element, the second seal element comprising a third slit defining a second portion of the first seal opening, and a fourth slit defining a second portion of the second seal opening, wherein the third slit is substantially perpendicular to the first slit, and wherein the fourth slit is substantially perpendicular to the second slit; and
(iii) a third seal element positioned between the second seal element and the first top ring, the third seal element comprising a first opening defining a third portion of the first seal opening, and a second opening defining a third portion of the second seal opening;

(d) a second top ring defining a second top ring opening, the second top ring configured to be operably coupled to the first top ring; and
(e) at least one second seal disposed between the first top ring and the second top ring, the at least one second seal further defining the at least first and second seal openings, wherein the at least one second seal comprises:
(i) a fourth seal element positioned adjacent to the first top ring, the fourth seal element comprising a fifth slit defining a fourth portion of the first seal opening, and a sixth slit defining a fourth portion of the second seal opening;
(ii) a fifth seal element positioned adjacent to the fourth seal element, the fifth seal element comprising a seventh slit defining a fifth portion of the first seal opening, and an eighth slit defining a fifth portion of the second seal opening, wherein the seventh slit is substantially perpendicular to the fifth slit, and wherein the eighth slit is substantially perpendicular to the sixth slit; and
(iii) a sixth seal element positioned between the fifth seal element and the second top ring, the sixth seal element comprising a third opening defining a sixth portion of the first seal opening, and a fourth opening defining a sixth portion of the second seal opening;

wherein the second top ring opening, the first top ring opening, the base ring opening and the first seal opening are configured to receive a surgical device positioned therethrough, and
wherein the base ring, the first top ring, the second top ring, and the at least one first and second seals are configured to maintain a fluidic seal at the incision providing access to the insufflated body cavity in the patient when the surgical device is positioned therethrough.
