Abstract

A wound protector and retractor device comprising a longitudinal axis, a distal ring, a proximal ring, and a sleeve extending between the distal ring and the proximal ring. The sleeve is fixed to the proximal ring at a first end portion and axially slidable over the proximal ring at a second end portion.

Claims

1. A wound protector and retractor device, comprising:

a longitudinal axis;

a distal ring;

a proximal ring; and

a sleeve extending at least between the distal ring and the proximal ring, the sleeve being fixed to the proximal ring at a first end portion of the sleeve, and a second end portion of the sleeve being slidingly received over a portion of the proximal ring.

2. The wound protector and retractor device of claim 1, wherein the sliding of the second end portion of the sleeve over a portion of the proximal ring allows relative movement between the sleeve and the proximal ring to shorten an axial extent of the sleeve located between the distal ring and the proximal ring.

3. The wound protector and retractor device of claim 2, wherein the portion of the proximal ring that slidingly receives the sleeve includes an outer portion of the proximal ring.

4. The wound protector and retractor device of claim 1, wherein the second end portion of the sleeve is biased against the proximal ring.

5. The wound protector and retractor device of claim 1, wherein the proximal ring is located within the sleeve.

6. The wound protector and retractor device of claim 1, wherein the proximal ring forms a part of a securing arrangement configured to substantially fix the axial extent of the sleeve located between the distal ring and the proximal ring at a desired length.

7. The wound protector and retractor device of claim 6, wherein the securing arrangement further includes a drawstring coupled to the second end portion of the sleeve.

8. The wound protector and retractor device of claim 1, wherein the proximal ring is formed of an elastomeric material.

9. The wound protector and retractor device of claim 1, wherein the distal ring is formed of an elastomeric material.

10. The wound protector and retractor device of claim 1, wherein the sleeve is wrapped around the distal ring.

11. The wound protector and retractor device of claim 1, wherein the sleeve has a generally uniform cross-sectional size in a plane normal to the longitudinal axis, the cross-sectional size of the sleeve being substantially equal to a size of at least one of the proximal and distal rings.

12. The wound protector and retractor device of claim 11, wherein the cross-sectional size of the sleeve is substantially equal to a size of both of the proximal and distal rings.

13. The wound protector and retractor device of claim 1, wherein an inner diameter of the proximal ring is substantially equal to an inner diameter of the distal ring.

14. The wound protector and retractor device of claim 1, wherein the proximal ring and distal ring are substantially equal in size.

15. The wound protector and retractor device of claim 1, wherein at least one of the proximal and distal rings includes a substantially circular shape.

16. The wound protector and retractor device of claim 15, wherein both of the proximal and distal rings include a substantially circular shape.

17. The wound protector and retractor device of claim 1, wherein at least one of the proximal and distal rings includes a circular cross-section in a plane containing the longitudinal axis.

18. The wound protector and retractor device of claim 17, wherein both of the proximal and distal rings include a circular cross-section in planes containing the longitudinal axis.

19. A method for retracting an incision comprising the steps of:

making an incision in a patient;

providing a wound retractor comprising a central longitudinal axis, a distal ring, a proximal ring, and a sleeve extending at least between the distal ring and the proximal ring, the sleeve being fixed to the proximal ring at a first end portion of the sleeve, and a second end portion of the sleeve being slidingly received over a portion of the proximal ring;

inserting the distal ring through the incision such that the sleeve extends through the incision and the proximal ring is located outside of the incision; and

moving the sleeve relative to the proximal ring to shorten an axial extent of the sleeve located between the distal ring and the proximal ring.

20. A method as claimed in claim 19, wherein the step of moving the sleeve relative to the proximal ring includes sliding a portion of the sleeve against a radially outer portion of the proximal ring.

21. A method as claimed in claim 19, wherein the proximal ring is located radially within an end portion of the sleeve.

22. A method as claimed in claim 19, further comprising the step of securing the sleeve to maintain the shortened axial extent of the sleeve located between the distal ring and the proximal ring.

23. A method as claimed in claim 22, wherein the step of moving the sleeve relative to the proximal ring includes tightening a drawstring coupled to a proximal end portion of the sleeve.

24. A method as claimed in claim 23, wherein the step of securing the sleeve includes fixing the drawstring in the tightened position.

25. A method as claimed in claim 19, wherein a portion of the sleeve located between the distal ring and the proximal ring includes two material layers.

26. A method as claimed in claim 25, wherein the sleeve is wrapped around the distal ring to form the two material layers.

27. A method as claimed in claim 26, wherein the distal ring is formed of an elastomeric material.

28. A method as claimed in claim 27, wherein the proximal ring is formed of an elastomeric material.

29. A method as claimed in claim 19, wherein the sleeve has a generally uniform cross-sectional size in a plane normal to the longitudinal axis, the cross-sectional size of the sleeve being substantially equal to a size of at least one of the proximal and distal rings.

30. A method as claimed in claim 29, wherein the cross-sectional size of the sleeve is substantially equal to a size of both of the proximal and distal rings.

31. A method as claimed in claim 19, wherein an inner diameter of the proximal ring is substantially equal to an inner diameter of the distal ring.

32. A method as claimed in claim 19, wherein the proximal ring and distal ring are substantially equal in size.

33. A method as claimed in claim 19, wherein at least one of the proximal and distal rings includes a substantially circular shape.

34. A method as claimed in claim 33, wherein both of the proximal and distal rings include a substantially circular shape.

35. A method as claimed in claim 19, wherein at least one of the proximal and distal rings includes a circular cross-section in a plane containing the longitudinal axis.

36. A method as claimed in claim 35, wherein both of the proximal and distal rings include a circular cross-section in planes containing the longitudinal axis.
