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) stretchabl e 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 great er 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 general ly 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 an d 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 associate d method includes the step of rolling the second ring circumferentially of the third ring (83) to form the circumferential retainer.

摘要： A surgical access device is adapted to facilitate access through an incision in a body wall having an inner surface and an outer surface, and into a body cavity of a patient. The device includes first and second retention members adapted to be disposed in proximity to the outer surface and the inner surfa ce of the body wall, respectively. A membrane extending between the two retenti on members forms a throat which is adapted to extend through the incision and form a first funnel extending from the first retention member into the throa t, and a second funnel extending from the second retention member into the throat. 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 may include a ring with either a fixed or variable diameter. The ring can be formed in first and second sections, each having two ends. Couplings can be disposed between the ends to accommodate variations in the size of the first retention member. Th e first retention member can also be formed as an inflatable toroid, a self- expanding foam, or a circumferential spring. A plurality of inflatable chambers can also provide the surgical access device with a working channel adapted for disposition across the body wall. A first retention member with a plurality of retention stations functions with a plurality of tethers connected to the membrane to change the shape of the membrane and the workin g channel. A stabilizing platform can be used to support the access device generally independent of any movement of the body wall.

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.
摘要翻译：外科伤口牵开器（12）适于扩张可拉伸至期望直径的伤口（10），牵开器包括第一环（14），该第一环的直径大于伤口所需的直径并且适于在伤口内部布置。第二环（16）的直径大于伤口所需的直径并且适于在伤口外部布置。多个回缩元件（36）在第一环（14）和第二环（16）之间以大致圆柱形的关系设置。这些元件延伸穿过伤口以在伤口上施加径向回缩力，这取决于分隔第一环和第二环的距离。预期收缩元件和可扩张元件均具有在环上的适当附接装置以提供收缩力的变化。戒指也可以做成可充气或自我膨胀来改变收缩力。相关联的方法包括沿第三环（83）的周向滚动第二环以形成周向保持器的步骤。
