    摘要： A surgical access device is adapted for performing laparoscopic surgical procedures with at least one instrument passing through the surgical access device and through an incision in the abdominal wall of a patient with the abdominal cavity pressurized with an insufflation gas. The surgical access device comprises an access seal. The material of the access seal is adapted to form a seal to generally maintain insufflation pressure within the abdominal cavity. At least one opening is formed through the material of the access seal between a proximal portion and a distal portion of the access seal. The at least one opening when operatively disposed is in communication with the incision and forms a working channel between a location external to the abdominal wall and a location internal to the abdominal wall. The material of the access seal conforms to a surface of an instrument inserted through the working channel.

    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 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 access device includes a single valve that forms a seal with the 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 with instruments having a full range of instrument diameter. The valve can include a gel and preferably an ultragel comprised of an elastomer and an 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, thereby providing hand access into the cavity. A method for making the surgical access device includes the combining of a gelling agent with an oil, preferably in a molding process. A method for using the device includes steps for creating an opening with the instrument. In a particular process, 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. The valve and method are particularly adapted for laparoscopic surgery wherein the abdominal cavity is insufflated with a gas thereby requiring the zero seal, the instrument seal, and the organ seal in various procedures.

    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： The invention is directed to a device and method for securing a passed surgical suture in a manner similar to a tied knot. The suture securing device comprises a male piece having a top portion, a center shaft having one end connected to the top portion, and an end member having a capturing feature connected to another end of the center shaft; and a female piece having a top end and a bottom end comprising a column being generally cylindrical in shape and forming a hollow opening along its length, wherein the opening slidingly receives the center shaft and a suture to be captured and held by the capturing feature, the suture being secured in place between the column and the center shaft. The assembled male and female pieces are irreversibly interlocked and form a lightly compressed, convoluted or tortuous pathway. The capturing feature is formed to engage and obliquely capture the suture from different angles.
