Wound Protector

摘要

In one embodiment, the wound protector has an annularly collapsible proximal ring and a flexible sleeve extends between the proximal ring and distal ring. After positioning of the distal ring in a wound, the proximal ring is expanded to draw the sleeve taut between the rings 11, 12 and is drawn tight against the wound.;In a second embodiment, the wound protector has a flexible sleeve secured between a distal ring and proximal ring of fixed diameters. In addition, an expansion member is disposed within a loop of the flexible sleeve about the proximal ring. After positioning of the distal ring in a wound, movement of the expansion member into an extended diametric state expands the loop in the sleeve diametrically while drawing the rings towards each other.

1. A wound protector comprising
a collapsible distal ring; an annularly collapsible proximal ring, said proximal ring being circumferentially collapsible from an extended state wherein the diameter of said proximal ring is larger than the diameter of said distal ring to a collapsed state wherein the diameter of said proximal ring is of the same size as the diameter of said distal ring; and a flexible sleeve extending between said proximal ring and said distal ring to form a frusto-conical shape with the proximal ring in said extended state and to collapse with said proximal ring in said collapsed state.
