Abstract: A surgical access apparatus adaptable to permit the sealed insertion of either the surgeon's hand and/or surgical instruments during laparoscopic and endoscopic surgical procedures includes an access housing defining a longitudinal axis and having a first internal passageway configured and dimensioned to permit passage of at least one of a hand and an arm of a surgeon, and a base mountable to the access housing. The base may include a liner member positionable within an incision of a patient to at least partially line the incision. A displacement member may be operatively connected to the access housing and to the liner member. The displacement member is adapted for movement to cause corresponding displacement of the liner member relative to the access housing whereby the liner member engages tissue forming the incision to at least partially retract the incision.

Abstract: A surgical seal assembly for use with a surgical access device includes a seal housing defining a central longitudinal axis and having a longitudinal passage dimensioned to permit passage of a surgical instrument through the seal housing, a gimbal mount disposed within the seal housing and having a gimbal seal member defining an aperture for substantial sealed reception of the surgical instrument, and an interface seal disposed within the seal housing. The gimbal mount is adapted for angular movement relative to the central longitudinal axis upon angulation of the surgical instrument whereby the gimbal seal member substantially maintains the sealed reception of the surgical instrument. The interface seal includes an interface seal member extending at least along the longitudinal axis and being in substantial contacting sealing relation with the gimbal mount. The interface seal member is adapted to maintain the sealing relation with the gimbal mount upon angular movement thereof.

Abstract: An optical obturator apparatus includes an obturator sleeve defining a longitudinal axis and having a longitudinal bore for receiving surgical instrumentation and a transparent window mounted to the obturator sleeve and being dimensioned and configured to pass through tissue. The transparent window is mounted for movement between a first position in general alignment with the longitudinal axis of the obturator sleeve and a second position radially displaced from the longitudinal axis to thereby expose the longitudinal bore of the obturator sleeve to permit passage of the surgical instrumentation. The transparent window may include a cutting blade, or alternatively two cutting blades, adapted to penetrate tissue.
