ABSTRACT:
An endoscopic surgical apparatus is provided for enabling the surgeon to access directly the surgical site during an endoscopic procedure. The apparatus includes an opening extending longitudinally through the apparatus and being configured and dimensioned to receive a hand therethrough. A first plate engages against the outer surface of the abdominal wall. A second plate is spaced from the first plate and is movable between a first position and a second position wherein the second plate is in close cooperative alignment with the inner surface of the abdominal wall. An adjustment member is mounted to the second plate and actuates movement of the second plate between its first position and its second position. A first sealing member inhibits the flow of gas through said opening and is formed by a pair of overlapping seals. A flexible sleeve extends between the first and second plates and adjusts in length to accommodate various thicknesses of the abdominal wall. The sleeve also creates an access port for the passage of objects through the abdominal wall.
