Zusammenfassung:A cannula for providing a pathway for surgical instruments in a minimally invasive procedure having a flexible body portion having a flexible flange extending radially outwardly from the distal region of the flexible body portion. A first seal is positioned within the body portion to prevent egress of fluids from the body of the patient. A rigid ring is positioned at the distal region of the body portion, the ring having an opening dimensioned to receive at least a distal portion of an obturator tip therethrough and a surface surrounding the opening in the ring onto which at least a portion of the obturator contacts to prevent further passage of the obturator.
