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 the 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.

18. The access port of claim 17, further comprising a pair of drawstrings attached to opposite ends of the flap valve and pulling the ends in opposite directions to enhance the sealing ability of the flap valve.
19. The access port of claim 12, further comprising a light source connected to the skirt in the vicinity of the exit opening.
20. The access port of claim 12, wherein the flexible sleeve comprises an iris valve.
21. The access port of claim 12, further comprising an inflatable cuff attached to an inner surface of the sleeve for sealing around a surgeon's arm. 45
22. The access port of claim 21, wherein the inflatable cuff is surrounded by a backing of a substantially non-expandable material.
23. The access port of claim 22, further comprising a second ring connected to the sleeve and surrounding the open end of the sleeve.
24. The access port of claim 23, further comprising a detachable cap for sealing the open end of the sleeve, wherein the detachable cap is adapted to be received by the second ring.
25. The access port of claim 12, further comprising : a sealing collar attached to the sleeve and surrounding the open end, said sealing collar having a groove along its inner perimeter; and a glove comprising a flange at the open end of the glove that mates with the groove and seals the channel when inserted into the groove.
26. The access port of claim 12, further comprising: a sealing collar attached to the sleeve and surrounding the open end, said sealing collar including an inwardly expanding inflatable bladder; and a glove having an enlarged cuff, wherein when the glove is inserted into the sleeve, the enlarged cuff mates with the inflated bladder and seals the opening. 46
27. The access port of claim 12, further comprising: a sealing collar attached to the sleeve and surrounding the open end, said sealing collar having a groove along its inner perimeter; a bracelet having a fixed diameter that mates with the groove; and a glove, wherein during use the bracelet is worn by a surgeon underneath the glove and is mated to the sealing collar, a portion of the glove being held within the groove by the bracelet, thereby sealing the channel.
28. A surgical access port, for use with a surgical glove, comprising: a device for retracting the edges of a surgical incision to form an opening into a patient's body cavity; a sealing sleeve attached to the device external to the body cavity, wherein the sealing sleeve comprises, a flexible sleeve providing a channel from its open end distal to the retracting device through to the opening, and a sealing collar attached to the sleeve and surrounding the open end; and a semi-rigid bracelet separable from the glove and having a fixed diameter that releasably mates with the sealing collar, the bracelet being configured to fasten a portion of the glove to the sealing collar when worn beneath the glove and mated to the sealing collar.
