    • The invention is directed to a hand access system that provides hand access to a surgical area while maintaining pneumoperitoneum during laparoscopic surgery. The hand access system comprises a sheath retractor adapted to dilate a wound stretchable to a desired diameter, the sheath retractor includes a first ring being adapted for disposition interiorly of the wound, a second ring being adapted for disposition exteriorly of the wound, and a sheath being disposed in a generally cylindrical form between the first ring and the second ring and operable to exert a radial retraction force on the wound. The hand access system further comprises a detachable hand seal adapted to be removable from the second ring of the sheath retractor. The sheath retractor may be formed of an elastomeric material, and the hand seal may be formed of a gel material and includes a slit providing an instrument seal in the presence of an instrument or hand and a zero seal in the absence of the instrument or hand. In another aspect, there is disclosed a surgical access device adapted for disposition relative to an incision in a patient comprising a valve including a plurality of overlapping sheets defining an access channel, and a ring having an inner diameter for holding the valve by fixing each of the overlapping sheets along a portion of the perimeter, the access channel extends into communication with the incision in the patient. Each of the overlapping sheets includes a portion of the perimeter that is not fixed to the inner diameter of the ring, which provide open edges defining the access channel. The open edges slightly overlap at the center of the ring. The open edges may have different shapes including at least one of a straight edge, concave, convex and a cross-configuration. The hand access device may further comprise a septum seal formed at the proximal and distal ends of the ring.
    • 本发明涉及一种手动进入系统,其在腹腔镜手术期间提供手术进入手术区域同时保持气腹。 手动进入系统包括一个适合于将可拉伸到所需直径的伤口扩张的护套牵开器,所述护套牵开器包括适于在伤口内部配置的第一环,适于在伤口外部配置的第二环, 在第一环和第二环之间以大致圆柱形的形式设置并可操作以在伤口上施加径向缩回力。 手动进入系统还包括适于从皮带牵开器的第二环移除的可拆卸手动密封件。 护套牵开器可以由弹性体材料形成,并且手动密封件可以由凝胶材料形成,并且包括在没有仪器或手的情况下在仪器或手的存在下提供仪器密封的狭缝和零密封 。 另一方面,公开了一种外科进入装置,其适于相对于患者的切口进行配置,该装置包括阀,所述阀包括限定出入通道的多个重叠片,以及具有用于通过固定每个 沿着周边的一部分重叠的片材,进入通道延伸成与患者的切口连通。 每个重叠片材包括未固定到环的内径的周边的一部分,其提供限定接入通道的开口边缘。 开口边缘在环的中心稍微重叠。 开口边缘可以具有不同的形状,包括直边,凹形,凸形和交叉构型中的至少一个。 手动进入装置还可以包括形成在环的近端和远端的隔膜密封件。

    • 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.
    • 外科伤口牵开器适于将可拉伸至期望直径的伤口扩张,牵开器包括直径大于伤口所需直径的第一环,并适于在伤口内部配置。 第二环的直径大于伤口所需的直径,并且适于在伤口的外部配置。 多个退回元件在第一环和第二环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缩回力,这取决于分离第一环和第二环的距离,缩回元件是可伸长的和不可扩张的,在环处有合适的附接装置,以提供 收缩力的变化。 利用合适的缩回套筒,可以提供第三环以形成圆周保持器以改变收回力。 环也可以制成充气或自膨胀以改变收缩力。相关联的方法包括在第三环周向滚动第二环以形成圆周保持器的步骤。
