What is claimed is:

1. A device for cutting a surgical cable, comprising:

an intervention unit comprising first and second coaxial members each comprising at least two openings in a distal end; and

a handle unit comprising an actuatable handle adapted to retain and engage the first and second coaxial members at a proximal end and to rotate the second coaxial member relative to the first;

wherein the at least two openings in the distal ends of the coaxial members function as coordinating shearing structures when the actuatable handle is actuated.

2. The device of claim 1, wherein the first and second coaxial members are configured with the second coaxial member inside the first, and the distal end of the second coaxial member abutting the first coaxial member along the longitudinal axis.

3. The device of claim 1, wherein the first and second coaxial members each comprise three openings in the distal end.

4. The device of claim 3, wherein the alignment of the three openings in one coaxial member is changeable with respect to the three openings in the other coaxial member.

5. The device of claim 3, wherein the proximal ends of the first coaxial member and the second coaxial member are characterized by a first shape to mate with a congruent shape on a pinion or coupling that allows for a rotational force to be transmitted by the mated shapes.

6. The device of claim 1, wherein the device is actuated by rotation of the second coaxial member relative to the first when the actuatable handle is actuated.

7. The device of claim 6, wherein the second coaxial member is attached to a pinion and wherein the actuatable handle comprises a first set of teeth that is configured to engage a second set of teeth attached to the pinion.

8. The device of claim 1, wherein the intervention unit is removably attached to the handle unit.

9. The device of claim 8, wherein the intervention unit is removably attached to the handle unit using a connection nut.

10. The device of claim 1, wherein the handle unit allows for coincident radial alignment of the first coaxial member relative to the second coaxial member in multiple positions all leading to alignment of the at least two openings in the distal ends of the coaxial members.

11. The device of claim 8, wherein the at least two openings are arranged in such a way that a change of alignment occurs coincidentally during each re-attachment of the intervention unit to the handle unit.

12. The device of claim 1, wherein the length of the device remains constant when the actuatable handle is actuated.

13. A surgical device for translating grip force to cutting force comprising:

an intervention unit comprising

an inner tubular member disposed coaxially within an outer tubular member; and a handle unit comprising

a housing;

a coupling disposed at the distal end of the housing;

a movable pinion coupled to the coupling; and

a squeezable grip coupled to the movable pinion and adapted to actuate axial rotation of the movable pinion against the coupling;

wherein the squeezable grip comprises a first set of teethed portions configured to engage a second set of teethed portions attached to the movable pinion.

14. The device of claim 13, wherein the inner tubular member and outer tubular member each have at least two openings on a distal end, the openings configured to translate a shear force between them when the inner tubular member and outer tubular member are rotated relative to each other.

15. The device of claim 13, wherein the inner and outer tubular member each have three openings on a distal end.

16. The device of claim 15, wherein the alignment of the three openings in one tubular member is changeable with respect to the three openings in the other tubular member.

17. The device of claim 15, wherein the proximal ends of the inner and outer tubular members are characterized by a first shape to mate with a congruent shape on the pinion or coupling that allows for a rotational force to be transmitted by the mated shapes.

18. The device of claim 13, wherein the handle unit comprises a first stationary member attached to the coupling member and a second movable member configured to engage the movable pinion, the first and second members being pivotally attached, the inner tubular member and the outer tubular member having a length sufficient to position the handle unit outside the patient.

19. The device of claim 14, wherein the intervention unit is removably attached to the handle unit.

20. The device of claim 19, wherein the intervention unit is removably attached to the handle unit using a connection nut.

21. The device of claim 14, wherein the handle unit allows for coincident radial alignment of the inner tubular member relative to the outer tubular member in multiple positions all leading to alignment of the at least two openings in the distal ends of the tubular members.

22. The device of claim 19, wherein the at least two openings are arranged in such a way that a change of alignment occurs coincidentally during each re-attachment of the intervention unit to the handle unit.

23. The device of claim 13, wherein the length of the device remains constant when the grip is squeezed.

24. A device for cutting a surgical cable comprising:

first and second gripping members pivotally attached to one another;

first and second handle grips attached at proximal ends of the first and second gripping members, respectively;

an outer tubular member attached on a proximal end of the outer tubular member to a distal end of the first gripping member;

an inner tubular member located within the outer tubular member and having at least one coupling member attached on a circumference of a proximal end; and

a movable pinion attached on a circumference of the proximal end of the coupling member;

wherein a distal end of the second gripping member is engaged with a proximal end of the movable pinion;

wherein the distal end of the inner tubular member abuts an internal surface of the outer tubular member proximal the distal end thereof, the outer tubular member and inner tubular member comprising at least two openings at the distal ends thereof that are substantially aligned to form a passage allowing a surgical cable to pass through and to exert a shearing force on the cable when the inner tubular member rotates with respect to the outer tubular member in response to compressing the first and second handle grips.

25. The device of claim 24, wherein the outer and inner tubular members each comprise three openings in the distal end.

26. The device of claim 25, wherein the alignment of the three openings in one tubular member is changeable with respect to the three openings in the other tubular member.

27. The device of claim 25, wherein the proximal ends of the outer and inner tubular members are characterized by a first shape that mates with a congruent shape on the pinion or coupling that allows for a rotational force to be transmitted by the mated shapes.

28. The device of claim 24, wherein the second gripping member comprises a first set of teeth that is configured to engage a second set of teeth attached to the movable pinion.

29. The device of claim 24, wherein the inner and outer tubular members are removably attached to the first and second gripping members.
