Abstract

An instrument access device comprises at least a first instrument seal 71 to effect a seal around a first instrument extended through the device and a second instrument seal 72 to effect a seal around a second instrument extended through the device. The instrument seals 71, 72 are configured to be arranged in a sealing relationship to a body of a patient. The device also comprises a distal anchoring ring 401 for location within a wound interior and a retractor member 402 extending proximally from the distal anchoring ring 401 to retract laterally the sides of a wound opening.

Claims

1. An instrument access device comprising:

a wound retractor including;

a proximal ring-shaped portion for location externally of a wound opening;

a distal ring-shaped portion for location within a wound interior;

a retraction portion extending proximally from the distal portion to the proximal portion to retract laterally the sides of the wound opening; and

a seal assembly including;

a first instrument seal spaced proximally the proximal ring-shaped portion of the wound retractor and laterally movable with respect to the proximal ring-shaped portion;

a second instrument seal spaced proximally the proximal ring-shaped portion of the wound retractor and laterally movable with respect to the proximal ring-shaped portion;

a third instrument seal spaced proximally the proximal ring-shaped portion of the wound retractor and laterally movable with respect to the proximal ring-shaped portion; and

the first instrument seal being larger than the second and third instrument seals;

the second and third instrument seals having substantially the same size; and

the first, second, and third instrument seals being oriented in a generally triangular at-rest configuration.

2. A device according to claim 1, wherein the seal assembly further includes separate, proximally extending connector tubes coupled to respective instrument seals.

3. A device according to claim 2, wherein each of the connector tubes is laterally flexible.

4. A device according to claim 2, wherein each of the connector tubes is oblique to one another and oblique to a longitudinal axis of the wound retractor.

5. A device according to claim 2, wherein each of the connector tubes is longitudinally rigid.

6. A device according to claim 1, further including a connector base portion configured to releasably mount the seal assembly to the proximal ring-shaped portion.

7. A device according to claim 6, wherein the connector base portion includes a proximally extending dome portion.

8. A device according to claim 6, wherein the connector base portion includes a radially outer protruding member configured to engage with a radially inner part of the proximal ring-shaped portion.

9. A device according to claim 1, wherein the seal assembly further includes an insufflation port separate from the instrument seals.

10. A device according to claim 1, wherein the size of each of the instrumental seals ranges from 5 mm to 12 mm.

11. A device according to claim 1, wherein the distal ring-shaped portion includes an O-ring.

12. A device according to claim 11, wherein the retraction portion includes a retracting sleeve.

13. A device according to claim 12, wherein the retracting sleeve extends in two layers between the distal ring-shaped portion and the proximal ring-shaped portion.

14. An instrument access device comprising:

a wound retractor including;

a proximal ring-shaped portion for location externally of a wound opening;

a distal ring-shaped portion for location within a wound interior;

a retraction portion extending proximally from the distal portion to the proximal portion to retract laterally the sides of the wound opening; and

a seal assembly including;

a first instrument seal spaced proximally the proximal ring-shaped portion of the wound retractor and laterally movable with respect to the proximal ring-shaped portion;

a second instrument seal spaced proximally the proximal ring-shaped portion of the wound retractor and laterally movable with respect to the proximal ring-shaped portion;

a third instrument seal spaced proximally the proximal ring-shaped portion of the wound retractor and laterally movable with respect to the proximal ring-shaped portion

a fourth instrument seal spaced proximally the proximal ring-shaped portion of the wound retractor and laterally movable with respect to the proximal ring-shaped portion; and

the first instrument seal being larger than the second, third, and fourth instrument seals;

the second and third instrument seals having substantially the same size;

the first, second, and third instrument seals being orientated in a generally triangular at-rest configuration; and

the fourth instrument seal being located between the second and third instrument seals.

15. A device according to claim 14, wherein the seal assembly further includes separate, proximally extending connector tubes coupled to respective instrument seals.

16. A device according to claim 15, wherein each of the connector tubes is laterally flexible.

17. A device according to claim 15, wherein each of the connector tubes is oblique to one another and oblique to a longitudinal axis of the wound retractor.

18. A device according to claim 15, wherein each of the connector tube is longitudinally rigid.

19. A device according to claim 14, further including a connector base portion configured to releasably mount the seal assembly to the proximal ring-shaped portion.

20. A device according to claim 19, wherein the connector base portion includes a proximally extending dome portion.

21. A device according to claim 19, wherein the connector base portion includes a radially outer protruding member configured to engage with a radially inner part of the proximal ring-shaped portion.

22. A device according to claim 14, wherein the distal ring-shaped portion includes an O-ring.

23. A device according to claim 14, wherein the retraction portion includes a retracting sleeve.

24. A device according to claim 23, wherein the retracting sleeve extends in two layers between the distal ring-shaped portion and the proximal ring-shaped portion.

25. An instrument access device comprising:

a wound retractor including;

a proximal ring-shaped portion for location externally of a wound opening;
