Abstract

A device for maintaining a body organ during surgery includes a flexible enclosure having at least one opening large enough to permit the body organ to pass through and including means for limiting closure of the opening such that injury to the body organ is minimized.

Claims

1. A device for maintaining a body organ during surgery, comprising:

a flexible enclosure having first and second openings, the first opening being large enough to permit the body organ to pass through;

means for closing the first opening of the flexible enclosure; and

semi-rigid means for limiting closure of the first opening such that injury to the body organ is minimized, the semi-rigid means including sleeve means proximate the opening and forming a circumferential passage, drawstring means including at least one drawstring positioned in the circumferential passage and a flexible tube having a passage extending therethrough, the flexible tube being positioned in the circumferential passage, and at least one draw string being positioned in the passage of the tube.

2. The device of claim 1 wherein the flexible enclosure is transparent.

3. The device of claim 1 wherein the flexible enclosure is of plastic construction.

4. The device of claim 1 wherein the flexible enclosure is constructed of plastic having a thickness of about 0.002 to 0.008 inch.

5. The device of claim 1 wherein the flexible enclosure is opaque.

6. The device of claim 1 wherein the flexible enclosure has a substantially cylindrical portion.

7. The device of claim 1 wherein the flexible enclosure has a tapered portion tapering inwardly toward the first opening.

8. The device of claim 1 wherein the flexible enclosure is substantially impermeable to liquids.

9. The device of claim 1 and further including a drawstring lock in cooperative engagement with the drawstring.

10. The device of claim 9 wherein the drawstring lock comprises:

a compression spring;

a plunger portion having a first locking surface, an outer surface and a pair of oppositely spaced holes on the outer surface for encircling the drawstring; and

a barrel portion having an outer surface, a pair of oppositely spaced holes on the outer surface for encircling the drawstring, an aperture for receiving the first locking surface, and an inner annular space for containing the compression spring.

11. The device of claim 1 wherein the flexible tube has a tube wall and a plurality of notches cut through a portion of the tube wall sufficiently deep to provide sufficient flexibility such that the tubing bends and still provides protection to the body organ.
