Abstract
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 and is drawn tight against the wound. In one embodiment, the proximal ring includes a bent hollow tube with an arcuate rod in the tube bridging the open ends of the tube and a compression spring extending within the tube against the ends of the rod to bias the proximal ring into an extended state. Finger grips on the ends of the tube allow for squeezing of the tube into a collapsed state.
