    摘要： A surgical access device includes a single valve that forms a seal with a body wall and provides an access channel into a body cavity. The valve has properties for creating a zero seal in the absence of an instrument as well as an instrument seal for an instrument having a diameter up to about 37 mm. The valve can include a gel material and the access channel can include a protective sleeve to provide for wound protection during insertion and withdrawal of a sharp surgical instrument. The valve further comprises a cap ring which may be inserted or molded with the gel material. The protective sleeve may be bonded or molded around an inner diameter of the cap ring. The protective sleeve may be a single tubular member, or may comprise a plurality of axially extending sleeve members having a plurality of axial slits. The protective sleeve and the cap ring may comprise of the same or different materials. The surgical access device further comprises at least one support ring disposed circumferentially of the valve forming a hollow space, and a wound retractor operatively placed in the hollow space. The wound retractor includes an inner ring, an outer ring, and a flexible sleeve connecting the inner ring and the outer ring.

    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.
