    摘要： An incrementally adjustable wound retractor, which provides access to a body cavity, includes an inner ring having a diameter greater than the desired diameter of the wound incision, an outer ring having an annular axis and a diameter greater than the desired diameter of the wound incision, and a flexible sleeve disposed in a generally cylindrical form between the inner and outer rings. The outer ring includes first and second circular tubes spaced apart axially with each including a lumen having a rigid, noncompliant split hoop placed therein. The outer ring may be rolled over itself and around the annular axis to retract the sleeve with sufficient force to stretch the incision to the desired diameter. A gel cap seal may be coupled to the outer ring outside of the biological body to seal the opening produced by the wound retractor between the body cavity and outside the body cavity.

    摘要： A surgical access port comprises a valve or instrument seal that separates the instrument contact function from the instrument conforming function. Embodiments of the instrument seal comprise in instrument contact element that extends through an opening in a compression element, thereby defining an instrument orifice that seals with an instrument extending therethrough. Embodiments of the instrument contact element comprise a non-distensible membrane or film, for example, as a tube or cylinder. Some embodiments of the instrument contact element have an hourglass configuration with a first end proximal of the opening of the compression element and a second end distal of the opening of the compression element. Other embodiments of the instrument contact element “wrap around” the opening in the compression element, with the first end and the second end secured to the same side of the opening, for example, proximal of the opening. Embodiments of the compression element comprise an elastomeric seal, for example, a septum seal and/or a gel seal.

    摘要翻译： 手术进入口包括将仪器接触功能与仪器符合功能分开的阀或仪器密封件。 仪器密封件的实施例包括在通过压缩元件中的开口延伸的仪器接触元件中，从而限定与延伸穿过其中的仪器密封的仪器孔。 仪器接触元件的实施例包括不可扩张的膜或膜，例如作为管或气缸。 仪器接触元件的一些实施例具有沙漏构造，其具有靠近压缩元件的开口的第一端和压缩元件的开口的远端的第二端。 仪器接触元件的其他实施例“包裹”压缩元件中的开口，其中第一端和第二端固定到开口的相同侧，例如开口的近侧。 压缩元件的实施例包括弹性体密封件，例如隔膜密封件和/或凝胶密封件。

    摘要： A surgical access device has a surgical retractor having a noncompliant outer ring with an annular axis, an inner ring, and a sleeve coupling the outer ring to the inner ring. The noncompliant outer ring is adapted to roll over itself around the annular axis to roll the sleeve around the outer ring to retract and seal an opening in a biological body wall. The access device may include a lid adapted for being coupled to the noncompliant outer ring of the surgical retractor. The outer ring of the surgical retractor has a cross-sectional shape that prohibits the lid from being partially or incorrectly coupled to the outer ring of the surgical retractor.

    摘要： A balloon trocar includes a cannula assembly including a cannula and an outer sleeve fitting over the cannula. The distal end of the outer sleeve is proximal to the distal end of the cannula. A balloon is coupled to a distal portion of the sleeve and a distal portion of the cannula. The outer surface of the cannula includes a plurality of longitudinal channels for transmitting gas or fluid to the balloon. A bolster having a gel pad at its distal portion is slidably mounted to the cannula assembly and may be locked in a desired position. In use, the trocar is inserted into an incision through a body wall and into a body cavity. The balloon is inflated and the cannula assembly pulled proximally against the incision while the bolster is slid distally to the body wall and locked in place to seal the incision with the compressed balloon.
