Abstract

A seal comprises a first sealing member and a second sealing member. The sealing members each have an accessway to facilitate access from one side of the sealing member to the other side of the sealing member. The accessways are offset to facilitate sealed access of an object through the sealing members.

Claims

1. A surgical method for providing access through a wound opening, the method including:

inserting a wound protector into the wound opening, wherein inserting the wound protector includes;

positioning a distal ring of the wound protector such that the distal ring is distal of the wound opening,

positioning a proximal ring assembly of the wound protector such that the proximal ring assembly is proximal of the wound opening, the proximal ring assembly having a proximal ring member and a sealing member, the sealing member having a plurality of access portions that provide access through the sealing member, and

positioning a sleeve of the wound protector in the wound opening, the sleeve extending between the proximal ring member and the distal ring; and

rotatably moving at least one of the plurality of access portions about a central longitudinal axis of the proximal ring assembly from a first rotational position relative to the proximal ring member to a second rotational position relative to the proximal ring member, wherein the first rotational position is different than the second rotational position.

2. The surgical method of claim 1, wherein rotatably moving at least one of the plurality of access portions about the central longitudinal axis of the proximal ring assembly includes rotatably moving the at least at least one of the plurality of access portions along a circular path, a central longitudinal axis of the at least one of the plurality of access portions being offset from the central longitudinal axis of the proximal ring assembly.

3. The surgical method of claim 1, wherein rotatably moving at least one of the plurality of access portions about the central longitudinal axis of the proximal ring assembly includes rotatably moving a first access portion and a second access portion about the central longitudinal axis of the proximal ring assembly, wherein the first access portion is on a first side of the central longitudinal axis of the proximal ring assembly, and the second access portion is on a second side of the central longitudinal axis of the proximal ring assembly, wherein the first and second sides are opposite sides of the central longitudinal axis of the proximal ring assembly.

4. The surgical method of claim 1, wherein rotatably moving at least one of the plurality of access portions about the central longitudinal axis of the proximal ring assembly includes rotatably moving at least three access portions about the central longitudinal axis of the proximal ring assembly.

5. The surgical method of claim 4, wherein a path traveled by one of the at least three access portions is shorter than paths traveled by the other of the at least three access portions.

6. The surgical method of claim 1, further including:

inserting a first object through a first access portion of the plurality of access portions; and

inserting a second object through a second access portion of the plurality of access portions, the first and second objects having different width dimensions, and the first and second access portions having different width dimensions.

7. The surgical method of claim 1, further including inserting an object through the at least one of the plurality of access portions, the at least one of the plurality of access portions including a sealing element that provides a seal around an exterior surface of the object, wherein the seal is maintained during rotational movement of the at least one of the plurality of access portions.

8. A surgical method for providing access through a wound opening, the method including:

inserting a wound protector into the wound opening, wherein inserting the wound protector includes;

positioning a distal ring of the wound protector such that the distal ring is distal of the wound opening,

positioning a proximal ring assembly of the wound protector such that the proximal ring assembly is proximal of the wound opening, the proximal ring assembly having a proximal ring member and a sealing member, the sealing member having a plurality of access portions that provide access through the sealing member, and

positioning a sleeve of the wound protector in the wound opening, the sleeve extending between the proximal ring member and the distal ring; and

rotating the sealing member about a central longitudinal axis of the proximal ring assembly in at least one of a clockwise and a counterclockwise direction.

9. The surgical method of claim 8, further including inserting at least one object through the at least one access portion.

10. The surgical method of claim 9, wherein the sealing member is rotated with the object within the at least one access portion.

11. The surgical method of claim 9, further including sealing around an exterior surface of the object with at least one seal member in the at least one access portion.

12. The surgical method of claim 11, wherein the sealing takes place in an area proximal to the proximal ring member.

13. The surgical method of claim 8, wherein the at least one access portion includes first, second, and third access portions, wherein each of the first, second, and third access portions includes a central longitudinal axis, and wherein the central longitudinal axes of the first, second, and third access portions define vertices of a triangle.

14. A surgical method for providing access through a wound opening, the method including:

inserting a wound protector into the wound opening, wherein inserting the wound protector includes;

positioning a distal ring of the wound protector such that the distal ring is distal of the wound opening,

positioning a proximal ring assembly of the wound protector such that the proximal ring assembly is proximal of the wound opening, the proximal ring assembly having a proximal ring member and a sealing member, the sealing member having a plurality of access portions that provide access through the sealing member, and

positioning a sleeve of the wound protector in the wound opening, the sleeve extending between the proximal ring member and the distal ring; and

inserting a first object through a first access portion of the sealing member;

inserting a second object through a second access portion of the sealing member; and

repositioning the first object and the second object, wherein repositioning includes rotating the sealing member about a central longitudinal axis of the proximal ring assembly.

15. The surgical method of claim 14, further including sealing around an external surface of the first object with a first sealing member of the first access portion.

16. The surgical method of claim 15, wherein the sealing is maintained during repositioning.

17. The surgical method of claim 14, further including inserting a third object through a third access portion of the sealing member.

18. The surgical method of claim 17, wherein inserting the first, second, and third objects in the first, second, and third access portions positions the first, second, and third objects in a triangular configuration on the sealing member.

19. The surgical method of claim 14, wherein inserting the first object through the first access portion includes introducing the first object into the first access portion at an area proximal to the proximal ring member.

20. The surgical method of claim 14, wherein rotating the sealing member includes sliding an edge of the sealing member along a surface of the proximal ring member.
