    摘要: A tissue collection apparatus is adapted for use in capturing and removing tissue through a hole in a body wall defining a body cavity. The apparatus includes an elongate flexible enclosure sized and configured to extend through the hole with a first end of the enclosure positioned within the body cavity and a second end of the enclosure positioned outside the body cavity. Portions of the distal end define opposing first and second edges which define an opening into the enclosure. A flap extends through the opening and distally of the apparatus to form a lip facilitating placement of tissue through the opening and into the enclosure. The coupling attaches a tension member to the enclosure along at least a point disposed not more distally than the flap. The tension member can be pulled proximally through the hole in the body wall to invert the apparatus without inverting the flap so that the flap covers the second edge of the opening in order to substantially close the opening with the tissue disposed within the enclosure. A method of use includes the steps of pulling the tension member to invert the enclosure and during the pulling step covering the opening with the flap.

    摘要: A tissue isolation and removal device has a containment pouch that is opened and supported by the device. The pouch has two open/close portions both able to be closed and reopened. One portion positioned away from tissue being inserted in the pouch and covering the other portion to enclose or isolate any tissue captured in the other portion.

    摘要: A wound retractor for retracting a surgical incision includes an inner ring, an outer ring and a distensible sleeve coupled to the inner and outer rings. The outer ring includes at least a pair of circular tubes coupled to each other. At least one of the circular tubes includes a lumen and a split that forms open ends. A noncompliant tubular hoop having a split therein is positioned in the lumen. The tubular hoop is oriented with its open ends positioned away from the split of the circular tubes. A core is positioned in the lumen of the tubular hoop. The core has a first end and a second end and is oriented with the ends positioned away from the split in the tubular hoop. The circular tubes may be parallel or may form a helical pattern similar to a Mobius strip.

    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: 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 retraction device for retracting an incision in a body wall includes a sheath that traverses through the incision from outside the body to a body cavity inside the body. The retraction device may include a deployable, adjustable frame that supports the sheath and that, together with the sheath, retracts the incision. The retraction device may include an outer ring and an inner ring coupled to opposing ends of the sheath and further include means to place the sheath in tension between the inner and outer rings, thereby retracting the incision.
