Abstract

A surgical clamp includes a shaft having clamping jaws at a proximal end and an operative handle assembly at a distal end. The shaft has properties for being moved to a desired shape by the user prior to operation of the handle assembly and for holding the desired shape during operation of the handle assembly. The shaft may include a bendable element extending along an axis between the handle assembly and the jaws. A control element disposed relative to the bendable element is operable from the handle assembly at the proximal end of the shaft to move the jaws relative to each other at the distal end of the shaft. An associated method includes the step of bending the shaft to a desired shape prior to operation of the clamp and maintaining the shaft in substantially the desired shape during operation of the clamp.

Claims

1. A surgical clamp, comprising:

a semi-rigid shaft extending between a proximal end and a distal end;

a pair of clamping jaws disposed at the distal end of the semi-rigid shaft and movable relative to each other to clamp an object between the jaws;

a handle assembly disposed at the proximal end of the semi-rigid shaft, the handle assembly being operable at the proximal end of the semi-rigid shaft to move the jaws relative to each other at the distal end of the semi-rigid shaft to clamp the object; and

the semi-rigid shaft being sufficiently flexible to be movable from a first shape into a desired, second shape, and being sufficiently rigid for maintaining the desired, second shape during operation of the handle assembly.

2. The surgical clamp recited in claim 1 wherein the shaft is malleable.

3. The surgical clamp recited in claim 1, further comprising:

a control element extending relative to the shaft and moveable by the handle assembly at the proximal end of the shaft to operate the jaws at the distal end of the shaft.

4. The surgical clamp recited in claim 3, wherein:

the shaft comprises a tube having a lumen; and

the control element is disposed relative to the lumen of the tube.

5. The surgical clamp recited in claim 4, wherein the control element has properties for being placed in tension to operate the jaws.

6. The surgical clamp recited in claim 5, wherein the control element has properties for being placed in compression to operate the jaws.

7. The surgical clamp recited in claim 5, wherein the control element includes a wire.

8. The surgical clamp recited in claim 6, wherein the tube of the shaft is a first tube and the control element comprises a second tube disposed relative to thie first tube.

9. The surgical clamp recited in claim 8, wherein the second tube is disposed interiorly of the first tube.

10. The surgical clamp recited in claim 8, wherein the second tube is disposed exteriorly of the first tube.

11. The surgical clamp recited in claim 5, wherein the jaws are movable between a first position and a second position and the surgical clamp further comprises:

a spring coupled to at least one of the jaws for biasing the jaws to the first position.

12. The surgical clamp recited in claim 11, wherein the first position is a closed position.

13. A surgical clamp, comprising:

a shaft extending between a proximal end and a distal end;

a pair of clamping jaws disposed at the distal end of the shaft and movable relative to each other to clamp an object between the jaws;

a handle assembly disposed at the proximal end of the shaft, the handle assembly being operable at the proximal end of the shaft to move the jaws relative to each other at the distal end of the shaft to clamp the object; and

the shaft comprising a semi-rigid bendable element extending along a first axis between the handle assembly and the jaws, the semi-rigid bendable element being sufficiently flexible to be movable from a first shape into a desired, second shape, and being sufficiently rigid for maintaining the desired, second shape during operation of the handle assembly; and

a control element extending relative to the bendable element along a second axis, the control element being operable from the handle assembly at the proximal end of the shaft to move the jaws relative to each other at the distal end of the shaft.

14. The surgical clamp recited in claim 13, Awherein the first axis of the bendable element is co-axial with the second axis of the control element.

15. The surgical clamp recited in claim 14, wherein:

the bendable element includes a tube; and

the control element is disposed within the tube of the bendable element.

16. The surgical clamp recited in claim 14, wherein:

the control element includes a tube; and

the bendable element is disposed within the tube of the control element.

17. The surgical clamp recited in claim 13, wherein the semi-rigid element is malleable.

18. The surgical clamp recited in claim 13, wherein the semi-rigid element is corrugated.

19. The surgical clamp recited in claim 13, wherein the semi-rigid element includes a series of ball-and-socket joints.

20. A method for operating a surgical clamp, comprising the steps of:

providing a shaft having a proximal end and a distal end with a pair of clamping jaws at the distal end and movable to clamp an object during a surgical operation, and a handle assembly disposed at the proximal end to operate the jaws at the distal end during the surgical operation;

bending the shaft to a desired shape prior to operation of the clamp; and

maintaining the shaft in substantially the desired shape without external force during operation of the clamp.

21. The method recited in claim 20, wherein the providing step includes the step of providing the shaft with a corrugated configuration.

22. The method recited in claim 20, wherein the providing step includes the step of providing the shaft in the form of a series of ball-and-socketjoints.
