    摘要: A surgical access system comprises a wound retractor comprising an outer anchor, an inner anchor, and a flexible, tubular sheath extending therebetween. Embodiments of the outer anchor comprise an outer ring rotatable around an annular axis thereof, thereby rolling the sheath therearound when retracting an incision or opening in a body wall. The sheath comprises a plurality of fibers or strands that improve the abrasion and puncture resistance thereof. Consequently, the surgical access system is useful in procedures in which damage to the sheath is likely, for example, orthopedic hip replacement, and spinal procedures. In some embodiments, the sheath tapers from the outer ring to the inner ring.

    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.

    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.
