Abstract

A wound retractor comprises a retracting member for insertion into a wound opening and a proximal member for location member for location externally of a wound opening. The proximal member is movable relative to the retracing member to shorten the axial extent of the retracting member to laterally retract a wound opening. The retracted wound opening is retracted by a seal which is integral with the retractor.

Claims

1. A surgical device comprising:

a wound retractor comprising;

a retracting member for insertion into a wound opening; and

a proximal member for location externally of a wound opening;

the proximal member being movable relative to the retracting member to shorten the axial extent of the retracting member to laterally retract a wound opening; and

a seal integral with the wound retractor, the seal including a chamber for receiving pressurized fluid to seal a retracted wound opening, and a sleeve having an inner sleeve section and an outer sleeve section with the chamber defined between the inner and outer sleeve sections, the sleeve being evertable upon advancement of an object through the sleeve.

2. A device as claimed in claim 1 wherein the proximal member comprises an annular ring assembly.

3. A device as claimed in claim 2 wherein the annular ring assembly comprises an inner ring and an outer ring between which the retracting member may be led.

4. A device as claimed in claim 3 wherein the inner ring defines a projection for location in a complementary recess of the outer ring with the retracting member located therebetween.

5. A device as claimed in claim 4 wherein the inner ring is a relatively loose fit in the recess of the outer ring.

6. A device as claimed in claim 4 wherein the inner ring is a relatively tight fit in the recess of the outer ring to grip the retracting member therebetween.

7. A device as claimed in claim 4 wherein at least a portion of one of the rings is movable from a rest position in which the retracting member is substantially clamped between the rings to a release position in which at least a portion of the retracting member is movable relative to the rings.

8. A device as claimed in claim 1 wherein the retracting member is provided by at least a portion of the outer sleeve section.

9. A device as claimed in claim 1 wherein the sleeve is turned axially back on itself to define the sleeve sections.

10. A device as claimed in claim 1 wherein the outer sleeve section is substantially cylindrical, and the inner sleeve section is twisted and of the same untwisted diameter as that of the outer sleeve section.

11. A surgical device comprising:

a retracting member movable from an insertion configuration to a retracting configuration to retract laterally a wound opening; and

a sleeve integral with the retracting member;

the sleeve having an inner sleeve section and an outer sleeve section with a chamber for receiving pressurized fluid between the inner and outer sleeve sections to seal a retracted wound opening, wherein the outer sleeve section is substantially cylindrical, and the inner sleeve section is twisted and of the same untwisted diameter as that of the outer sleeve section;

the sleeve being evertable upon advancement of an object through the sleeve to facilitate sealed access through a retracted wound opening.

12. A device as claimed in claim 11 wherein the retracting member is provided by at least a portion of the outer sleeve section.

13. A device as claimed in claim 11 wherein the sleeve is turned axially back on itself to define the sleeve sections.

14. A device as claimed in claim 11 wherein the device comprises a distal member coupled to a distal end of the retracting member for insertion into a wound opening.

15. A device as claimed in claim 14 wherein the distal member is of a resilient material.

16. A device as claimed in claim 14 wherein the distal member comprises an O-ring.

17. A surgical device comprising:

a wound retractor comprising;

a retracting member for insertion into a wound opening; and

a proximal member for location externally of a wound opening;

the proximal member being movable relative to the retracting member to shorten the axial extent of the retracting member to laterally retract a wound opening; and

a seal integral with the wound retractor, the seal including a chamber for receiving pressurized fluid to seal a retracted wound opening, and a sleeve having an inner sleeve section and an outer sleeve section with the chamber defined between the inner and outer sleeve sections, the outer sleeve section being substantially cylindrical, and the inner sleeve section being twisted and of the same untwisted diameter as that of the outer sleeve section.

18. A device as claimed in claim 17 wherein the proximal member comprises an annular ring assembly.

19. A device as claimed in claim 18 wherein the annular ring assembly comprises an inner ring and an outer ring between which the retracting member may be led.

20. A device as claimed in claim 19 wherein the inner ring defines a projection for location in a complementary recess of the outer ring with the retracting member located therebetween.

21. A device as claimed in claim 20 wherein the inner ring is a relatively loose fit in the recess of the outer ring.

22. A device as claimed in claim 20 wherein the inner ring is a relatively tight fit in the recess of the outer ring to grip the retracting member therebetween.

23. A device as claimed in claim 20 wherein at least a portion of one of the rings is movable from a rest position in which the retracting member is substantially clamped between the rings to a release position in which at least a portion of the retracting member is movable relative to the rings.

24. A device as claimed in claim 17 wherein the retracting member is provided by at least a portion of the outer sleeve section.

25. A device as claimed in claim 17 wherein the sleeve is turned axially back on itself to define the sleeve sections.
