Device, surgical access port, and method of retracting an incision into an opening and providing a channel through the incision
First Claim
1. A device for retracting edges of an incision in a surface to form an opening, the device comprising:
- a flexible, tubular skirt having an upper end, a lower end, and a channel therebetween;
a non-inflatable 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, wherein the ring is designed to fit through the incision and remain under the surface when it is oriented parallel to surface and is configured to contact an underside of the surface; and
an inflatable collar connected to the skirt and surrounding the upper end, wherein the collar, when fully inflated, maintains the upper end in an open configuration and defines an entry opening to the channel.

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.

27. 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. - View Dependent Claims (28, 29)

30. A surgical access port comprising:
-
a device for retracting the edges of a surgical incision to form an opening into a patient'"'"'s body cavity, the retracting device comprising an upper portion for overlying tissue surrounding the incision, a lower portion for underlying the tissue surrounding the incision, and a flexible skirt connecting the upper and lower portion, all of which permit the retracting device to form a gas-tight seal with the edges of the incision; and 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 drawstrings connected to the flexible sleeve for sealing the channel.

31. A surgical access port comprising:
-
a device for retracting the edges of a surgical incision to form an opening into a patient'"'"'s body cavity; and 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; drawstrings connected to the flexible sleeve for sealing the channel; and
an outer sleeve surrounding the flexible sleeve and forming a chamber therebetween, and an inlet port for inflating the chamber, whereby inflating the chamber compresses together a central portion of the flexible sleeve, thereby sealing the channel, and wherein the drawstrings attach to opposite sides of the central portion of the flexible sleeve.

32. A surgical access port comprising:
-
a device for retracting the edges of a surgical incision to form an opening into a patient'"'"'s body cavity; and 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; drawstrings connected to the flexible sleeve for sealing the channel; and
a flap valve that connects to the open end of the flexible sleeve and extends into the channel, wherein the flap valve seals the channel when there is a positive pressure differential between the channel and the surroundings, and wherein the drawstrings attach to opposite ends of the flap valve to enhance the sealing ability of the flap valve.

33. A device for retracting edges of an incision in a surface to form an open channel, the device comprising:
-
an upper toroidal portion for positioning above the surface around the incision, the upper toroidal portion defining and enclosing an inflatable, sealed interior; a lower portion insertable through the incision and orientable to underlie the surface beneath the incision; and a flexible, gas-tight tubular skirt having an upper end connected to the upper toroidal portion and a lower end connected to the lower portion, wherein during use the lower portion maintains the lower end in an open configuration, the upper toroidal portion, lower portion, and skirt defining an open channel extending through the incision, the channel having side-walls that are gas impermeable. - View Dependent Claims (34, 35, 36, 37, 38, 39)

40. A method of retracting an incision into an opening and providing a channel through the incision, the channel having gas-impermeable sides and the method comprising:
-
inserting a ring at one end of a gas-tight tubular skirt through the incision and orienting the ring to underlie and contact tissue surrounding the incision; orientating a toroidal upper portion at an opposite end of the gas-tight tubular skirt to overlie and contact tissue surrounding the incision; and expanding the toroidal upper portion, while maintaining the contact between the toroidal upper portion and the tissue surrounding the incision, to thereby draw the skirt outward from the incision, retract the incision into an opening, and provide the channel through the incision. - View Dependent Claims (41, 42, 43)
