1. A wound retractor device, comprising:
- a longitudinal axis;
a distal ring;
a proximal ring;
a retracting member extending between the distal ring and the proximal ring, the retracting member being movable relative to the proximal ring to shorten an axial extent of the retracting member located between the distal ring and the proximal ring;
a retracting member securement, the securement operable automatically upon removal of a force used to shorten an axial extent of the retracting member located between the distal ring and proximal ring; and
a seal extending across an access opening of the wound retractor device.

Abstract
A wound protector retractor comprises an inner O-ring for insertion through a wound opening and a connecting sleeve extending between the O-ring and outer mounting means. The outer means are provided by rings between which the sleeve is led. The rings are rotated relative to each other and the inner ring to form a centralised lumen of reduced cross section and to shorten the axial extent of the sleeve. A wound is both retracted and protected.

11. A wound retractor device, comprising:
-
a longitudinal axis; a distal ring; a proximal ring; a retracting member extending between the distal ring and the proximal ring, the retracting member being movable relative to the proximal ring to shorten an axial extent of the retracting member located between the distal ring and the proximal ring; a locking means for automatically securing a shortened axial extent of the retracting member between the distal ring and proximal ring upon removal of a force used to shorten said axial extent; and a seal extending across an access opening of the wound retractor device. - View Dependent Claims (12, 13, 14, 15, 16, 17)

18. A method for retracting an incision, comprising:
-
making an incision in a patient; providing a wound retractor comprising a central longitudinal axis, a distal ring, a proximal ring, and a retracting member extending at least between the distal ring and the proximal ring; inserting the distal ring through the incision such that the retracting member extends through the incision and the proximal ring is located outside of the incision; applying a force to move the retracting member relative to the proximal ring in the longitudinal direction to shorten an axial extent of the retracting member located between the distal ring and the proximal ring, the retracting member being automatically secured at a desired axial extent between the distal ring and proximal ring upon removal of the force; and sealing an access opening of the wound retractor. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26)
