Abstract

A surgical stay including a hook, a handle and an elastomeric band. The hook has a tissue engaging portion and is retained by the handle such that the tissue engaging portion extends from a first end of the handle. A handle end of the band is retained by a second end of the handle. The band has a longitudinal body and at least one hub disposed around the body. The hub has a generally flat engagement surface facing the handle.

Claims

1. A surgical stay comprising a hook, a handle and an elastomeric band, the hook having a tissue engaging portion, the hook being retained by the handle such that the tissue engaging portion extends from a first end of the handle and a proximal end of the band being retained by a second end of the handle, the band having a longitudinal body and at least one hub disposed around the body, the hub having a generally flat engagement surface facing the handle.

2. The stay according to claim 1, wherein the engagement surface is adapted to make planar contact with a frame.

3. The stay according to claim 1, wherein the engagement surface is generally perpendicular to a longitudinal axis of the band.

4. The stay according to claim 1, wherein the body of the band and the hub are integrally molded.

5. The stay according to claim 1, wherein the handle includes a first member and a second member, the first member and the second member being adapted to mate together to independently retain the hook and the proximal end of the band.

6. The stay according to claim 5, wherein the band is provided with a retaining bulb at the proximal end of the band, the retaining bulb being trapped by the first and second handle members.

7. The stay according to claim 5, wherein the band defines a hole at the proximal end of the band and the first handle member is provided with a pin, the pin extending into the hole.

8. A band for a surgical stay comprising, an elastomeric longitudinal body having a proximal end and a distal end, and at least one hub disposed at a position between the proximal and distal ends of the body and extending radially from the body, the body and hub merging with one another at a location adjacent an engagement surface of the hub, said location defining a merger plane, the merger plane being transverse relative to a longitudinal axis of the body, said engagement surface being at least as close to the proximal end of the body as the merger plane.

9. The elastomeric band for a surgical stay according to claim 8, wherein the engagement surface is planar and is coincident with the merger plane.

10. The elastomeric band for a surgical stay according to claim 8, wherein the engagement surface is concave and faces the proximal end, the merger plane being tangent to the engagement surface.

11. The elastomeric band for a surgical stay according to claim 8, wherein the proximal end of the band is connected to a handle and hook assembly.

12. The elastomeric band for a surgical stay according to claim 8, further comprising a second longitudinal body having a proximal end and a distal end, and at least one hub disposed at a position between the proximal and distal ends of the second body and extending radially from the second body, and a broad body having a first end and a second end, the first end connected to the proximal end of the first longitudinal body and the second end connected to the proximal end of the second longitudinal body such that the broad body is disposed between the first and second longitudinal bodies.

13. The elastomeric band for a surgical stay according to claim 8, wherein the proximal end of the longitudinal body is connected to a broad body.

14. The elastomeric band for a surgical stay according to claim 13, wherein the broad body is elastomeric and integrally formed with the longitudinal body.

15. The elastomeric band for a surgical stay according to claim 13, wherein the broad body has a first end and a second end, and the first end and the second end are adapted to be fastened together.

16. The elastomeric band for a surgical stay according to claim 13, wherein the broad body has a first end and a second end, and the first end and the second end are connected to the proximal end of the longitudinal body.

17. A band for a surgical stay comprising, an elastomeric longitudinal body having a proximal end and a distal end, and at least one hub disposed at a position between the proximal and distal ends of the body and extending radially from the body, the body and hub merging with one another at a location adjacent an engagement surface of the hub, said location defining a merger plane, said merger plane being transverse relative to a longitudinal axis of the body, and at least a portion of the engagement surface being closer to the proximal end of the body than the merger plane.

18. A surgical stay comprising a first elastomeric band, a second elastomeric band and a broad body, each band having a longitudinal body with a proximal end and a distal end and at least one hub disposed around the longitudinal body, each hub having a generally flat engagement surface facing the proximal end of the respective longitudinal body the hub is disposed around, and the broad body having a first end and a second end, the proximal end of the first band connected to the first end of the broad body and the proximal end of the second band connected to the second end of the broad body.

19. A surgical stay comprising a hook, a handle and an elastomeric band, the handle having a first member and a second member, the first member and the second member being adapted to mate together to independently retain the hook and a proximal end of the band, wherein the band is provided with a retaining bulb at the proximal end of the band, the retaining bulb being trapped by the first and second handle members.

20. A surgical stay comprising a hook, a handle and an elastomeric band, the handle having a first member and a second member, the first member and the second member being adapted to mate together to independently retain the hook and a proximal end of the band, wherein the band defines a hole at the proximal end of the band and the first handle member is provided with a pin, the pin extending into the hole.

21. A surgical stay comprising a hook, a handle and an elastomeric band, the handle having a first member and a second member, the first member and the second member being adapted to mate together to independently retain the hook and a proximal end of the band, wherein the hook has a tissue engaging portion and a securing loop, the hook being retained by the handle such that the tissue engaging portion extends from the handle and the securing loop is trapped by the first and second handle members.
