    摘要: A surgical access device includes an access seal comprising an ultra gel elastomeric material formed of a mixture comprising a triblock copolymer and an oil. The access seal is adapted to be disposed relative to the abdominal wall. At least one access channel is formed through the elastomeric material between a proximal portion and a distal portion of the access seal. The access channel when operatively disposed forms at least a portion of a working channel between a location external to the abdominal wall and a location internal to the abdominal wall. The elastomeric material of the access seal is adapted to conform to a surface of an instrument inserted through the working channel to provide instrument access to the abdominal cavity while maintaining insufflation pressure in the abdominal cavity. The access channel is configured to self seal in the absence of any instrument extending through the access channel.

    摘要: A surgical access device includes a single valve forming a seal with the body wall and providing an access channel into a body cavity. The valve has properties for creating a zero-seal in the absence of an instrument and an instrument seal with instruments. The valve can include a gel comprised of an elastomer and oil providing elongation greater than 1000 percent and durometer less than 5 Shore A. The single valve can be used as a hand port where the instrument comprises the arm of a surgeon. A method for making the surgical access device includes combining a gelling agent with oil, preferably in a molding process. A method for using the device includes creating an opening with the instrument. An organ can be removed from the body cavity through the single valve to create an organ seal while the organ is addressed externally of the body cavity.

    摘要: A surgical wound retractor is adapted to dilate a wound stretchable to a desired diameter, the retractor includes a first ring having a diameter greater than that desired for the wound and being adapted for disposition interiorly of the wound. A second ring has a diameter greater than that desired for the wound and is adapted for disposition exteriorly of the wound. A plurality of retraction elements are disposed in a generally cylindrical relationship to each other, between the first ring and the second ring. 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. With a suitable retraction sleeve, a third ring can be provided to form a circumferential retainer to vary 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 to form the circumferential retainer.

    摘要: A surgical access device includes an access seal adapted to be disposed within an incision within an abdominal wall. The access seal has an external flange adapted to be disposed external to the abdominal wall and an internal flange adapted to be disposed internal to the abdominal wall. The access seal with flanges is formed monolithically. There are access channels through the access seal. The access channels span the thickness of the abdominal wall and form working channels between a location external to the abdominal wall and a location internal to the abdominal wall. The access seal is formed of an elastomeric material adapted to conform to a surface of an instrument inserted through the working channel to form an instrument seal along a length spanning the thickness of the abdominal wall. The elastomeric material is adapted to form an abdominal seal within the abdominal wall.
