摘要： A surgical device (50) is adapted to facilitate access through an incision (100) in a body wall (18) having an inner surface and an outer surface, and into a body cavity of a patinet. The device includes (55) and second (65) retention members adapted to be disposed in proximity to the outer surface and the inner surface of the body wall, respectively. A membrane (75) extending between the two retention members form a throat (90) which is adapted to extend through the incision (100) and form a first funnel extending from the first retention member (55) into the throat (90), and a second funnel extending from the second retention member (65) into the throat (90). The throat of the membrane has characteristics for forming an instrument seal in the presence of an instrument and a zero seal in the absence of an instrument. The first retention member (55) may include a ring with either a fixed or variable diameter.

摘要： A surgical wound retractor (12) is adapted to dilate a wound (10) stretchable to a desired diameter, the retractor includes a first ring (14) having a diameter greater than that desired for the wound and being adapted for disposition interiorly of the wound. A second ring (16) has a diameter greater than that desired for the wound and is adapted for disposition exteriorly of the wound. A plurality of retraction elements (36) are disposed in a generally cylindrical relationship to each other, between the first ring (14) and the second ring (16). These elements extend through the wound to exert a radial retraction force on the wound which is dependent on the distance separating the first ring and the second ring. Retraction elements, both distensible and non-distensible are contemplated with appropriate attachment means at the rings to provide for variations in the retraction force. Rings can also be made inflatable or self-expanding to vary the retraction force. An associated method includes the step of rolling the second ring circumferentially of the third ring (83) to form the circumferential retainer.
