Abstract

An instrument insertion device (1) comprises a first seal (2), a second seal (3), a first proximal ring (4) for location externally of a wound opening, and a second proximal ring (5) for location externally of the wound opening. The first seal (2) may be a tricuspid valve defining a passageway (6) extending therethrough. An instrument (7) may be inserted through the passageway (6). The passageway (6) is movable from the closed configuration to the open configuration upon insertion of the instrument (7) through the passageway (6). The passageway (6) is biased towards the closed configuration, such that upon removal of the instrument (7) from the passageway (6), the passageway (6) moves automatically from the open configuration to the closed configuration. The second seal (3) may be a lipseal valve with a passageway (8) extending therethrough. An instrument (7) may be inserted through the passageway (8). The passageway (8) is biased towards the open configuration, such that upon removal of the instrument (7) from the passageway (8), the passageway (8) moves automatically from the sealed configuration to the open configuration.

Claims

1. An instrument insertion device comprising:

a first seal member having a first passageway extending therethrough, through which an instrument is insertable; and

a second seal member having a second passageway extending therethrough, through which the instrument is insertable.

2. A device as claimed in claim 1 wherein the first passageway is movable between a closed configuration to seal a wound opening, and an open configuration to facilitate insertion of an instrument through the first passageway.

3. A device as claimed in claim 2 wherein the first passageway is movable from the closed configuration to the open configuration upon insertion of an instrument through the first passageway.

4. A device as claimed in claim 2 wherein the first passageway is biased towards the closed configuration.

5. A device as claimed in claim 1 wherein the first seal member has a protector to protect the seal member against damage by an instrument.

6. A device as claimed in claim 4 wherein the first seal member is divided into a number of sections and a protector is provided for at least some of the sections.

7. A device as claimed in claim 2 wherein in the closed configuration, the first passageway is provided in the form of one or more slits through the first seal member.

8. A device as claimed in claim 7 wherein the first passageway is provided in the form of three slits through the first seal member.

9. A device as claimed in claim 8 wherein the first seal member comprises a tricuspid valve.

10. A device as claimed in claim 1 wherein the second passageway is movable between an open configuration, and a sealed configuration to seal around an instrument inserted through the second passageway.

11. A device as claimed in claim 10 wherein the second passageway is movable from the open configuration to the sealed configuration upon insertion of an instrument through the second passageway.

12. A device as claimed in claim 10 wherein the second passageway is biased towards the open configuration.

13. A device as claimed in claim 10 wherein the second seal member comprises a lipseal valve.

14. A device as claimed in claim 1 wherein the first seal member is located proximally of the second seal member.

15. A device as claimed in claim 1 wherein the first seal member is located distally of the second seal member.

16. A device as claimed in claim 1 wherein the first seal member is formed separately from the second seal member.

17. A device as claimed in claim 1 wherein at least part of one of the seal members is longitudinally spaced apart from at least part of the other seal member.

18. A device as claimed in claim 1 wherein one of the seal members is movable relative to the other seal member.

19. A device as claimed in claim 1 wherein the first seal member is formed integrally with the second seal member.

20. A device as claimed in claim 1 wherein the device comprises a first proximal member for location externally of a wound opening.

21. A device as claimed in claim 20 wherein the seal member is coupled to the first proximal member.

22. A device as claimed in claim 21 wherein the seal member is fixed relative to the first proximal member.

23. A device as claimed in claim 21 wherein the seal member is movable relative to the first proximal member.

24. A device as claimed in claim 23 wherein the device comprises a connecting member to connect the seal member to the first proximal member.

25. A device as claimed in claim 24 wherein the connecting member is flexible.

26. A device as claimed in claim 25 wherein the connecting member comprises a sleeve.

27. A device as claimed in claim 20 wherein the device comprises a retracting member for extending through a wound opening to retract laterally the sides of the wound opening.

28. A device as claimed in claim 27 wherein the retracting member is extendable through the wound opening in two layers.

29. A device as claimed in claim 27 wherein the retracting member is attached to the first proximal member.

30. A device as claimed in claim 27 wherein the device comprises a distal member for location internally of a wound opening.

31. A device as claimed in claim 30 wherein the retracting member is coupled to the distal member.

32. A device as claimed in claim 31 wherein the retracting member is looped around the distal member.

33. A device as claimed in claim 27 wherein the device comprises a second proximal member for location externally of a wound opening.

34. A device as claimed in claim 33 wherein the second proximal member is coupled to the first proximal member.

35. A device as claimed in claim 33 wherein the retracting member is extendable between the first proximal member and the second proximal member.
