Abstract

A nonabsorbent holding member adapted for use within an abdominal cavity of a patient defined by an anterior wall, a posterior wall and two lateral walls to keep the patient'"'"'s bowels out of the operative field during open pelvic surgery. The holding member has a peripheral edge formed of a resiliently deformable material sized to be received within the abdominal cavity. The resilient deformation of at least a portion of the peripheral edge of the holding member results in a residual reactive force against the abdominal cavity to assist in positioning the holding member in the abdominal cavity.

Claims

1. Apparatus adapted for use within an abdominal cavity of a patient, said cavity defined by an anterior wall, a posterior wall and lateral walls, said apparatus comprising:

a U-shaped holding member adapted to be received in the patient'"'"'s abdominal cavity and having an edge formed of a resiliently deformable polymer and a core formed from a polymer that is more rigid than said resiliently deformable polymer, a resilient deformation of at least a portion of said edge of said holding member resulting in a residual reactive force against the abdominal cavity, said residual reactive force thereby assisting in positioning said holding member in the abdominal cavity;

at least one bore in said holding member wherein said at least one bore has a predetermined length; and

said core including a first plate and a second plate, said plates having an assembled length less than said predetermined length.

2. Apparatus of claim 1 wherein said edge is fabricated from foam.

3. Apparatus of claim 1 where said edge of said holding member is sized to extend beyond the cross-section of the patient'"'"'s relaxed abdominal cavity to enhance said residual reactive force.

4. Apparatus of claim 1 wherein the holding member is coated by a layer of polymer.

5. Apparatus of claim 1 wherein said edge of the holding member is flat.

6. Apparatus of claim 1 wherein said holding member having a presized indentation.

7. Apparatus of claim 6 wherein said indentation is adapted to be positioned about the patient'"'"'s aorta and vena cava.

8. Apparatus adapted for use within an abdominal cavity of a patient, said cavity defined by an anterior wall, a posterior wall and lateral walls, said apparatus comprising:

a U-shaped holding member adapted to be received in the patient'"'"'s abdominal cavity and having an edge formed of a resiliently deformable polymer and a core formed from a polymer that is more rigid than said resiliently deformable polymer;

at least one bore in said holding member wherein said at least one bore has a predetermined length; and

said core including a first plate and a second plate, said plates having an assembled length less than said predetermined length.

9. Apparatus of claim 8 wherein said edge is fabricated from foam.

10. Apparatus of claim 8 where said edge of said holding member is sized to extend beyond the cross-section of the patient'"'"'s relaxed abdominal cavity.

11. Apparatus of claim 8 wherein the holding member is coated by a layer of polymer.

12. Apparatus of claim 8 wherein said edge of the holding member is flat.

13. Apparatus of claim 8 wherein said holding member having a presized indentation.

14. Apparatus of claim 13 wherein said indentation is adapted to be positioned about the patient'"'"'s aorta and vena cava.

15. Apparatus adapted for use within an abdominal cavity of a patient, said cavity defined by an anterior wall, a posterior wall and lateral walls, said apparatus comprising:

a U-shaped holding member adapted to be received in the patient'"'"'s abdominal cavity and having an edge formed of a resiliently deformable polymer and a core formed from a polymer that is more rigid than said resiliently deformable polymer;

at least one bore in said holding member not in communication with said edge, wherein said at least one bore has a predetermined length.

16. Apparatus of claim 15 wherein said edge is fabricated from foam.

17. Apparatus of claim 15 where said edge of said holding member is sized to extend beyond the cross-section of the patient'"'"'s relaxed abdominal cavity.

18. Apparatus of claim 15 wherein the holding member is coated by a layer of polymer.

19. Apparatus of claim 15 wherein said edge of the holding member is flat.

20. Apparatus of claim 15 wherein said holding member having a presized indentation.
