Claim 11:
12. A surgical system comprising:
(a) a robotic surgical device comprising:
(i) an elongate body; and
(ii) first and second arms operably coupled to the elongate body;

(b) a surgical insertion device comprising:
(i) 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;
(ii) a first top ring defining a first top ring opening, the first top ring configured to be operably coupled to the base ring;
(iii) at least one first seal disposed between the base ring and the first top ring, the at least one first seal defining at least first and second seal openings, wherein the at least one first seal comprises:
(A) a first seal positioned adjacent to the base ring, wherein the first seal comprises:
(1) a first slit defining a first portion of the first seal opening; and
(2) a second slit defining a first portion of the second seal opening;

(B) a second seal positioned adjacent to the first seal, wherein the second seal comprises:
(1) a third slit defining a second portion of the first seal opening, wherein the third slit is substantially perpendicular to the first slit; and
(2) a fourth slit defining a second portion of the second seal opening, wherein the fourth slit is substantially perpendicular to the second slit; and

(C) a third seal positioned between the second seal and the first top ring, wherein the third seal comprises:
(1) a first opening defining a third portion of the first seal opening; and
(2) a second opening defining a third portion of the second seal opening;

(iv) 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
(v) 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:
(A) a fourth seal positioned adjacent to the first top ring, wherein the fourth seal comprises:
(1) a fifth slit defining a fourth portion of the first seal opening; and;
(2) a sixth slit defining a fourth portion of the second seal opening;

(B) a fifth seal positioned adjacent to the fourth seal, wherein the fifth seal comprises:
(1) a seventh slit defining a fifth portion of the first seal opening, wherein the seventh slit is substantially perpendicular to the fifth slit; and
(2) an eighth slit defining a fifth portion of the second seal opening, wherein the eighth slit is substantially perpendicular to the sixth slit;

(C) a sixth seal positioned between the fifth seal and the second top ring, wherein the sixth seal comprises:
(1) a third opening defining a sixth portion of the first seal opening; and
(2) 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 the robotic 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 robotic surgical device is positioned therethrough.
