Abstract

A surgical sealing device 1 for providing hand or instrument access during a surgical procedure is mounted to a wound retractor device 10 which is used to retract the sides of an opening into an internal cavity. The sealing device 1 comprises a first sealing member 5 and a second sealing member 6. The second sealing member 6 has passageway 2 with a sidewall of an elastic material to create a seal between the sidewall of the passageway 2 and an object passing through the passageway 2. The first sealing member 5 is in the form of a flap of flexible material and is moveable relative to the second sealing member 6 between a closed configuration sealing the passageway 2 and an open configuration. The flap member 5 may be fixedly attached to the second sealing member 6 by means of a reception loop 7 formed at the distal surface of the second sealing member 6.

Claims

1. A surgical sealing device comprising:

a sealing valve for sealing across an opening to an internal cavity;

the sealing valve comprising a first sealing member and a second sealing member;

the sealing members being movable relative to one another between a closed configuration in which the sealing members at least partially overlap one another for sealing across the opening, and an open configuration for facilitating passage of an object through the sealing valve to access the internal cavity,

the first sealing member being attached to the second sealing member.

2. A device as claimed in claim 1 wherein the device comprises a holder to hold the first sealing member attached to the second sealing member.

3. A device as claimed in claim 2 wherein the holder comprises a hinge.

4. A device as claimed in claim 2 wherein the holder comprises one or more fixing elements.

5. A device as claimed in claim 1 wherein the second sealing member comprises an access opening extending therethrough.

6. A device as claimed in claim 5 wherein the access opening is sized to seal with a surgeons forearm.

7. A device as claimed in claim 6 wherein the access opening is sized to seal with an instrument shaft.

8. A device as claimed in claim 5 wherein the second sealing member comprises a lipseal.

9. A device as claimed in claim 5 wherein in the closed configuration, the first sealing member extends across the access opening to seal the access opening.

10. A device as claimed in claim 1 wherein the device comprises a connector member for connecting the sealing valve to a retractor device.

11. A device as claimed in claim 10 wherein the connector member is configured to extend substantially distally from the sealing valve to a retractor device.

12. A device as claimed in claim 10 wherein the connector member is of a flexible material.

13. A device as claimed in claim 10 wherein the connector member comprises a sleeve.

14. A device as claimed in claim 1 wherein the first sealing member is of a flexible material.

15. A device as claimed in claim 1 wherein the second sealing member is at least partially of a gelatinous elastomeric material.

16. A device as claimed in claim 1 wherein the second sealing member is at least partially of a TPE material.

17. A device as claimed in claim 1 wherein the second sealing member is at least partially of a silicone material.

18. A device as claimed in claim 1 wherein the first sealing member is biased towards the closed configuration.

19. A device as claimed in claim 1 wherein the second sealing member is substantially curved.

20. A device as claimed in claim 19 wherein a concave portion of the curved second sealing member faces distally.

21. A device as claimed in claim 18 wherein in the closed configuration, the first sealing member is substantially curved.

22. A device as claimed in claim 21 wherein in the closed configuration, a concave portion of the curved first sealing member faces distally.

23. A surgical assembly comprising:

a retractor device for retracting the sides of an opening to an internal cavity; and

a surgical sealing device as claimed in claim 1.

24. An assembly as claimed in claim 23 wherein the surgical sealing device is mounted to the retractor device.

25. An assembly as claimed in claim 23 wherein the sealing valve of the surgical sealing device is located adjacent to a proximal end of the retractor device.

26. An assembly as claimed in claim 23 wherein the sealing valve of the surgical sealing device is spaced-apart from the retractor device.

27. An assembly as claimed in claim 26 wherein the sealing valve is located proximally of the retractor device.
