Abstract

Device for supporting the abdominal wall away from organs positioned thereunder for freeing up a surgical space in minimally invasive surgery, having multiple tube-shaped hollow bodies, which are fillable via a hose line (6, 16), and which are connected to each other in circumferential direction to form a preferably conical toroidal shape. The elongated hollow bodies (2, 10) are each supported at their ends (4, 12) on a tube-shaped, thin-walled, foldable hollow body (8, 14), which forms a ring, and which can be filled via a hose line (6, 16), extending along the two edges of the toroidal shape. The diameters of the two annular hollow bodies (8, 14) may be the same, or different, thus forming a cylindrical or frustoconical wall (18) serving for support.

Claims

1-8. -8. (canceled)

9. A device for supporting the abdominal wall away from organs positioned thereunder for freeing up a surgical space in minimally invasive surgery, comprising:

a) multiple tube-shaped, thin-walled, foldable hollow bodies forming a toroidal shape, and being fillable via a hose line;

b) the tube-shaped hollow bodies being elongated, and extending in the direction of the toroidal shape;

c) the tube-shaped hollow bodies being connected to each other in a circumferential direction of the toroidal shape; and

d) the elongated bodies being supported in an axial direction of the toroidal shape at their ends on a respective tube-shaped, thin-walled, foldable hollow body, which form a ring, and being fillable via a hose line, and which extending along both edges of the toroidal shape.

10. The device according to claim 9, wherein:

a) diameters of the two hollow bodies forming a ring are different, such that the elongated hollow bodies form a frustoconical wall.

11. The device according to claim 9, wherein:

a) diameters of the two hollow bodies forming a ring are the same, such that the elongated hollow bodies form a cylindrical wall.

12. The device according to claim 9, wherein:

a) an interior of multiple, or of all hollow bodies are connected to each other.

13. The device according to claim 9, wherein:

a) interiors of the elongated hollow bodies are connected in axial direction to hollow space of the one hollow body, and, alternately, to hollow space of the other hollow body forming a ring; and

b) the annular hollow bodies each have respective dedicated hose lines for filling their hollow spaces, and each have respective hollow spaces of the elongated bodies connected to the same.

14. The device according to claim 9, wherein:

a) the hollow bodies are formed by two plastic sheets, which are welded to each other in the region of the boundaries of the hollow bodies.

15. The device according to claim 9, wherein:

a) protrusions are arranged on one or both of the hollow bodies each forming a respective ring, which can be connected to adjacent body parts, particularly to the abdominal wall, by means of surgical threads, in order to secure the device.

16. The device according to claim 15, wherein:

a) the protrusions are formed by individual tabs, or by circumferential protrusions.
