Abstract

Embodiments include a clamp for a medical procedure, the clamp having a first clamp member having a first end and a second end, a second clamp member having a first end and a second end, a hinge, the hinge coupling the first ends of the first and second clamp members, a biasing member, the biasing member coupling the second ends of the first and second clamp members, the biasing member being configured to apply a first clamping force in a first stage, and a second clamping force in a second stage, where the second clamping force is greater than the first clamping force.

First claim

What is claimed is:

1. A clamp for a medical procedure, the clamp comprising:
a first clamp member having a first end and a second end;
a second clamp member having a first end and a second end;
a hinge, the hinge coupling the first ends of the first and second clamp members such that the first clamp member is pivotable relative to the second clamp member;
a biasing member, the biasing member coupling the second ends of the first and second clamp members, wherein the biasing member is configured to apply a first clamping force in a first stage, and a second clamping force in a second stage, wherein the second clamping force is greater than the first clamping force;
a shaft, the shaft having a proximal end and a distal end, wherein the distal end of the shaft and the biasing member are fixedly coupled with at least one of the first clamp member or the second clamp member for a duration of the medical procedure;
an actuator, the actuator being operatively coupled with the biasing member such that the actuator selectively tensions the biasing member to provide the first clamping force in the first stage and the second clamping force in the second stage, wherein the first stage comprises the first clamping force being from about 0.5 g/mm 2 to about 4 g/mm 2 .

2. The clamp of claim 1 , wherein the hinge is a spring.

3. The clamp of claim 2 , wherein the spring is extensible such that the first end of the first clamp member and the first end of the second clamp member are spaced apart by a variable gap.

4. The clamp of claim 1 , wherein each of the first clamp member and the second clamp member have a rigid unitary construction.

5. The clamp of claim 1 , wherein the second stage comprises the second clamping force being from about 4 g/mm 2 to about 12 g/mm 2 .

6. The clamp of claim 1 , wherein the biasing member extends through at least a portion of the first clamp member and the second clamp member.

7. The clamp of claim 1 , where in the biasing member is a multi-strand stainless steel cable.

8. The clamp of claim 1 , wherein at least one of the first clamp member and the second clamp member include an alignment surface operably configured to engage a stapling device.

9. The clamp of claim 1 , further comprising an indicator of tissue thickness.

10. The clamp of claim 1 , further comprising a spring reel tensioning device.

11. A clamp for a medical procedure, the clamp comprising:
a first rigid clamp member having a first end and a second end;
a second rigid clamp member having a first end and a second end; and
a hinge, the hinge being an extensible spring coupling the first ends of the first and second rigid clamp members such that the first rigid clamp member is pivotable relative to the second rigid clamp member and such that the first end of the first rigid clamp member is spaced apart from the first end of the second rigid clamp member with a variable gap;
a metal biasing member, the metal biasing member coupling the second ends of the first and second rigid clamp members, wherein the metal biasing member applies a first clamping force in a first stage, and a second clamping force in a second stage, wherein the second clamping force is greater than the first clamping force;
a shaft, the shaft having a proximal end and a distal end, wherein the distal end of the shaft and the metal biasing member are fixedly coupled with at least one of the first rigid clamp member or the second rigid clamp member for a duration of the medical procedure;
an actuator, the actuator being operatively coupled with the metal biasing member such that the actuator selectively tensions the metal biasing member to provide the first clamping force in the first stage and the second clamping force in the second stage, wherein the first stage comprises the first clamping force being from about 0.5 g/mm 2 to about 4 g/mm 2 .

12. The clamp of claim 11 , wherein the metal biasing member is a multi-strand stainless steel cable.

13. The clamp of claim 11 , wherein the metal biasing member is selected from a group consisting of a flexible member, a chain, at least one link, and combinations thereof.

14. The clamp of claim 11 , wherein the second stage comprises the second clamping force being from about 4 g/mm 2 to about 12 g/mm 2 .

15. A clamp for a medical procedure, the clamp comprising:
a first rigid clamp member having a proximal end and a distal end;
a second rigid clamp member having a proximal end and a distal end; and
a hinge, the hinge being an extensible spring coupling the distal ends of the first and second rigid clamp members such that the first rigid clamp member is pivotable relative to the second rigid clamp member and such that the proximal end of the first rigid clamp member is spaced apart from the proximal end of the second rigid clamp member with a variable gap;
a metal biasing member, the metal biasing member coupling the proximal ends of the first and second rigid clamp members, wherein the metal biasing member applies a first clamping force in a first stage, and a second clamping force in a second stage, wherein the second clamping force is greater than the first clamping force;
a shaft, the shaft having a proximal end and a distal end, wherein the distal end of the shaft and the metal biasing member are fixedly coupled with at least one of the first rigid clamp member or the second rigid clamp member for a duration of the medical procedure;
an actuator, the actuator being operatively coupled with the metal biasing member such that the actuator selectively tensions the metal biasing member to provide the first clamping force in the first stage and the second clamping force in the second stage, wherein the first stage comprises the first clamping force being from about 0.5 g/mm 2 to about 4 g/mm 2 .

16. The clamp of claim 15 , wherein the metal biasing member is a multi-strand stainless steel cable.

17. The clamp of claim 15 , wherein the second stage comprises the second clamping force being from about 4 g/mm 2 to about 12 g/mm 2 .
