Manipulator tool and holding and/or expanding tool with at least one manipulator tool

1. A holding, expanding, or combinations thereof tool comprising at least two jaws opposite one another with respect to a space, wherein at least one jaw is movable with respect to the other jaw, and wherein at least one jaw is formed by a manipulator tool, and wherein the manipulator tool comprises:

a. a distal end movable in at least one manipulation plane with respect to a proximal end; and

b. at least two cheeks extending side by side to and spaced apart from each other, wherein the cheeks are flexible at least in the manipulation plane and extend from the proximal end to the distal end, wherein the cheeks are connected between the proximal end and the distal end by at least one at least tension-proof hinge element to permit a shearing movement relative to each other, wherein the cheeks are held at the proximal end at a distance from each other, wherein the one cheek is configured to be at least flexurally stiff and the other cheek to be at least tension-proof, and wherein the at least tension-proof cheek is connected at its distal end to the at least flexurally stiff cheek so as to transmit a pulling force, wherein one cheek is embodied to be driven at the proximal end in the longitudinal direction, wherein the holding, expanding or combinations thereof tool is formed in one piece.

2. The tool of claim 1 , wherein the cheek that is embodied to be driven at the proximal end in the longitudinal direction is configured to be tension-proof and flexurally stiff.

3. The tool of claim 1 , wherein the at least one jaw that is formed as the manipulator tool further comprises a tool holder disposed at the distal end.

4. The tool of claim 1 , wherein the at least one jaw that is formed as the manipulator tool is characterized in that said at least one flexurally stiff cheek comprises a stiffness changing in the direction from the proximal end to the distal end.

5. The tool of claim 1 , wherein the hinge elements are arranged around an interior.

6. The tool of claim 1 , wherein the space is open towards the distal end.

7. The holding, expanding or combinations thereof tool of claim 1 , wherein the at least tension-proof cheek is adjacent to the space.

8. The holding, expanding or combinations thereof tool of claim 1 , wherein the at least flexurally stiff cheek or the at least tension-proof cheek are connected to each other at the proximal end.

9. The holding, expanding or combinations thereof tool of claim 8 , wherein a coupling element is provided at the point of connection of the proximal end.

10. The holding, expanding or combinations thereof tool of claim 1 , wherein each jaw of the holding, expanding or combinations thereof tool is formed by one said manipulator tool.

11. The holding, expanding or combinations thereof tool of claim 1 , wherein both cheeks of the manipulator tool are stiff.

12. The holding, expanding or combinations thereof tool of claim 11 , wherein said cheeks include inner and outer cheeks, the inner cheeks facing the space having a smaller wall thickness than the outer cheeks.

13. The holding, expanding or combinations thereof tool of claim 1 , wherein said cheeks include inner and outer cheeks, the inner cheeks comprising a ribbing transverse to the longitudinal direction.

14. The holding, expanding or combinations thereof tool of claim 1 , wherein said cheeks include inner and outer cheeks, the inner cheeks being connected to a tool base via a joint.
