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 device, comprising:

a longitudinal axis;

a distal ring;

a proximal ring;

a wound retracting sleeve extending between the proximal ring and the distal ring and movable from an insertion configuration to a retracting configuration to retract laterally a wound opening so that an overall amount of sleeve extending between the distal ring and the proximal ring is less in the retracting configuration than in the insertion configuration, an opening through the wound retracting sleeve approaching a diameter of at least one of the distal ring and the proximal ring as the wound retracting sleeve moves from the insertion configuration to the retracting configuration, and an axial extent between the distal ring and the proximal ring being shorter in the retracting configuration than in the insertion configuration; and

a sealing member coupled to the proximal ring, the sealing member including

a dome shape when in use, and

at least three accessways on the dome shape to facilitate sealed access through the retracted opening, the accessways being located an axial distance proximal the proximal ring and configured to seal surgical instruments extending through the accessways, axes of at least two of the accessways converging to a point, the point being located below a circumferential extent of the sealing member, wherein the axes of at least two of the accessways and an axis of the sealing member are coplanar.

2. The surgical device of claim 1, wherein at least two of the accessways are on opposite sides of the sealing member.

3. The surgical device of claim 1, wherein the at least three accessways include first and second accessways located on opposite sides of a third accessway.

4. The surgical device of claim 1, wherein the sealing member is rotatable relative to the proximal ring.

5. The surgical device of claim 4, wherein the sealing member is rotatable about a central longitudinal axis of the proximal ring.

6. The surgical device of claim 1, wherein the axes of at least two of the accessways converge to the point when in use.

7. The surgical device of claim 1, wherein at least one accessway includes a seal.
