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.

Claims

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.

2. The wound retractor device of claim 1, wherein the securement includes a wedge.

3. The wound retractor device of claim 2, wherein the wedge is coupled to the proximal ring.

4. The wound retractor device of claim 1, wherein the securement includes the proximal ring.

5. The wound retractor device of claim 1, wherein the retracting member includes at least one strap.

6. The wound retractor device of claim 5, wherein the at least one strap includes a plurality of straps, each strap extending through the proximal ring.

7. The wound retractor device of claim 1, wherein the retracting member is coupled to the distal ring.

8. The wound retractor device of claim 1, wherein the seal extends between the distal and proximal rings.

9. The wound retractor device of claim 1, wherein the seal includes an iris diaphragm type device.

10. The wound retractor device of claim 1, wherein the retracting member includes a gripping portion extending away from the proximal ring, and the force used to shorten the axial extent of the retracting member includes a pulling force on the gripping portion of the retracting member.

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.

12. The wound retractor device of claim 11, wherein the retracting member includes at least one strap.

13. The wound retractor device of claim 12, wherein the at least one strap includes a plurality of straps, each strap extending through the proximal ring.

14. The wound retractor device of claim 11, wherein the retracting member is coupled to the distal ring.

15. The wound retractor device of claim 11, wherein the seal extends between the distal and proximal rings.

16. The wound retractor device of claim 11, wherein the seal includes an iris diaphragm type device.

17. The wound retractor device of claim 11, wherein the retracting member includes a gripping portion extending away from the proximal ring, and the force used to shorten the axial extent of the retracting member includes a pulling force on the gripping portion of the retracting member.

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.

19. The method of claim 18, wherein the automatic securing includes passing the retracting member through a wedge.

20. The method of claim 18, wherein the automatic securing includes the use of a ratchet mechanism.

21. The method of claim 18, wherein the retracting member includes at least one strap.

22. The method of claim 21, wherein the at least one strap includes a plurality of straps, each strap extending through the proximal ring.

23. The method of claim 18, wherein the retracting member is coupled to the distal ring.

24. The method of claim 18, wherein the seal extends between the distal and proximal rings.

25. The method of claim 18, wherein the seal includes an iris diaphragm type device.

26. The method of claim 18, wherein the retraction member includes a gripping portion extending away from the proximal ring, and the applying of a force includes a pulling force applied to a gripping portion.
