Abstract

A device for retracting edges of an incision in a surface to form an opening including: a flexible, tubular skirt having an upper end, a lower end, and a channel therebetween; a ring connected to the lower end of the skirt for maintaining the lower end in an open configuration and defining an exit opening to the channel; and an inflatable collar connected to the skirt and surrounding the upper end. The ring is designed to fit through the incision and remain under the surface when it is oriented parallel to surface. The collar, when inflated, maintains the upper end in an open configuration and defines an entry opening to the channel. During use, the ring is inserted through the incision and the collar is inflated while remaining outside of the incision, thereby drawing the skirt against the edges of the incision and retracting the edges of the incision to form the opening. The retracting device can be included in a surgical access port, which further includes a flexible sleeve connected to at least one of the inflatable collar and the skirt, extending the channel from the exit opening of the skirt to an open end of the flexible sleeve distal to the skirt. The device can include a light source in the vicinity of the exit opening.

Claims

1. A surgical apparatus comprising:

a tubular access port defining a passageway for accessing a patient'"'"'s body cavity through an incision, wherein

the access port comprises an inflatable portion, which when fully inflated maintains the passageway in an open configuration and no part of the inflatable portion closes the passageway, and

the access port further comprises a flap valve configured to seal an opening to the passageway.

2. The apparatus of claim 1, wherein the passageway and the flap valve are sized to receive a surgeon'"'"'s hand.

3. The apparatus of claim 1, wherein the tubular access port has a distal end configured to be inserted into the patient and a proximal end configured to receive a surgeon'"'"'s hand, and wherein the inflatable portion is positioned closer to the proximal end than the distal end.

4. The apparatus of claim 3, wherein the flap valve is positioned closer to the proximal end than the distal end.

5. The apparatus of claim 4, wherein the flap valve is positioned at the proximal end.

6. The apparatus of claim 5, wherein the flap valve comprises opposed portions extending into the passageway and configured to press against one another.

7. The apparatus of claim 3, wherein the access port further comprises a resilient ring encircling the passageway at the distal end of the access port.

8. The apparatus of claim 7, wherein during use the resilient ring is configured to underlie tissue surrounding the incision and maintain the distal end of the passageway in an open configuration.

9. The apparatus of claim 8, wherein during use the inflatable portion is configured to overlie the tissue surrounding the incision and in conjunction with the resilient ring secure the access port to the patient when fully inflated.

10. The apparatus of claim 1, wherein the inflatable portion encircling the passageway comprises an inflatable collar.

11. The apparatus of claim 1, wherein the access port further comprises an inflation port coupled to the inflatable portion.

12. The apparatus of claim 1, wherein the flap valve comprises opposed portions configured to press against one another.

13. The apparatus of claim 12, wherein the opposed portions are flattened portions.

14. The apparatus of claim 13, wherein the flattened opposed portions have edge portions that are sealed together.

15. The apparatus of claim 12, wherein the opposed portions are biased to press against one another.

16. The apparatus of claim 1, wherein tubular access port further comprises a flap valve assembly carrying the flap valve, and wherein the flap valve assembly is configured to releasably attach to the portion of the access port that defines the passageway.
