    摘要： A trocar fixation device includes a cannula and an elongate tube mounted onto and coupled to the exterior surface of the cannula with the distal end of the cannula extending distally beyond the distal end of the elongate tube. The elongate tube includes a plurality of slits cut at an angle to a longitudinal axis of the elongate tube. The trocar fixation device is activated by rotating the proximal-end region of the elongate tube in a first direction and is deactivated by rotating the proximal-end region of the elongate tube in a second direction, opposite to the first direction. Activation of the trocar fixation device compresses the material positioned between adjacent slits and forces the material radially outwardly, away from the exterior surface of the cannula, thereby forming ridges. Deactivation of the trocar fixation device returns the exterior surface of the elongate tube to a substantially smooth condition.

    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： 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.
