Abstract

An attachable clamp for use with a surgical instrument is disclosed. The attachable clamp comprises a body portion, a first jaw member, a second jaw member and an actuation mechanism. The body portion defines a longitudinal axis and has attachment members configured to attach to an elongate portion of a surgical instrument. Each of the first jaw member and second jaw member extends distally from the body portion. The actuation mechanism is disposed in mechanical cooperation with at least one of the first jaw member and the second jaw member. Actuation of the actuation mechanism moves at least one of the first and second jaw members between an approximated position and an open position with respect to the other jaw member.

First claim

The invention claimed is:

1. A surgical stapling instrument and an attachable clamp for use therewith, the attachable clamp comprising:
a body portion defining a first longitudinal axis and having attachment members configured to attach to an elongate portion of the surgical stapling instrument, the elongate portion of the surgical stapling instrument defining a second longitudinal axis, wherein the first longitudinal axis is spaced laterally from and substantially parallel with the second longitudinal axis;
a first jaw member extending distally from the body portion and being fixed from longitudinal movement with respect to the body portion;
a second jaw member extending distally from the body portion, wherein the first jaw member and the second jaw member correspond to jaws of the surgical stapling instrument in shape and orientation; and
an actuation mechanism disposed in mechanical cooperation with at least one of the first jaw member and the second jaw member, wherein actuation of the actuation mechanism moves at least one of the first and second jaw members between an approximated position and an open position with respect to the other jaw member;
wherein the attachable clamp is removable from and re-attachable to the surgical stapling instrument.

2. The surgical stapling instrument and attachable clamp of claim 1 , wherein the attachment members are configured to removably attach to the body portion and to removably attach to the elongate portion of the surgical stapling instrument.

3. The surgical stapling instrument and attachable clamp of claim 1 , wherein each of the first jaw member and the second jaw member are curved with respect to the first longitudinal axis.

4. The surgical stapling instrument and attachable clamp of claim 3 , wherein each of the first jaw member and the second jaw member includes a concave side and a convex side.

5. The surgical stapling instrument and attachable clamp of claim 4 , wherein the concave sides of the first jaw member and the second jaw member are disposed adjacent the jaws of the surgical stapling instrument.

6. The surgical stapling instrument and attachable clamp of claim 4 , wherein the convex sides of the first jaw member and the second jaw member are disposed adjacent the jaws of the surgical stapling instrument.

7. The surgical stapling instrument and attachable clamp of claim 1 , wherein the actuation mechanism includes a first cam plate disposed in mechanical cooperation with the first jaw member and disposed in mechanical cooperation with a rod, and wherein translation of the rod causes the first jaw member to move upwardly.

8. The surgical stapling instrument and attachable clamp of claim 7 , wherein the actuation mechanism further comprises a second cam plate disposed in mechanical cooperation with the second jaw member and disposed in mechanical cooperation with the rod, wherein translation of the rod causes the second jaw member to move downwardly.

9. The surgical stapling instrument and attachable clamp of claim 8 , wherein the translation of the rod in a first direction causes the second jaw member to move downwardly toward the open position.

10. The surgical stapling instrument and attachable clamp of claim 7 , wherein the translation of the rod in a first direction causes the first jaw member to move upwardly toward the open position.

11. The surgical stapling instrument and attachable clamp of claim 10 , wherein the rod is biased toward a position so that the first jaw member tends to move toward the approximated position.

12. The surgical stapling instrument and attachable clamp of claim 1 , wherein the first jaw member and the second jaw member are substantially parallel to one another when the jaw members are in the open and approximated positions.

13. The surgical stapling instrument and attachable clamp of claim 1 , wherein the first jaw member is stationary with respect to the body portion.

14. The surgical stapling instrument and attachable clamp of claim 1 , wherein the actuation mechanism includes a knob and a slide member, and wherein rotation of the knob causes the second jaw member to pivot towards the first jaw member.

15. The surgical stapling instrument and attachable clamp of claim 14 , wherein the knob includes a plurality of teeth which are configured to engage a plurality of teeth of the slide member.

16. The surgical stapling instrument and attachable clamp of claim 1 , where a distal portion of the body portion of the clamp is configured to selectively attach to a distal portion of an elongate portion of the surgical stapling instrument.

17. The surgical stapling instrument and attachable clamp of claim 16 , wherein a proximal portion of the body portion of the clamp is configured to selectively attach to a proximal portion of the elongate portion of the surgical stapling instrument.

18. The surgical stapling instrument and attachable clamp of claim 1 , wherein the body portion is configured to selectively attach to a lateral side of an elongate portion of the surgical stapling instrument.

19. The surgical stapling instrument and attachable clamp of claim 1 , wherein the elongated portion of the surgical stapling instrument is parallel with the body portion of the attachable clamp along an entire length of the body portion.

20. The surgical stapling instrument and attachable clamp of claim 1 , wherein a proximal-most end of the attachable clamp is configured to longitudinally align with the elongate portion of the surgical stapling instrument when the attachable clamp is engaged with the surgical stapling instrument.

21. A surgical stapling instrument and an attachable clamp for use therewith, the attachable clamp comprising:
a body portion defining a first longitudinal axis and having attachment members configured to attach to the surgical stapling instrument, at least one attachment member disposed adjacent a distal portion of the body portion and configured to attach to a distal portion of an elongate portion of the surgical stapling instrument;
a first jaw member extending distally from the body portion and being fixed from longitudinal movement with respect to the body portion;
a second jaw member extending distally from the body portion, wherein the first jaw member and the second jaw member correspond to jaws of the surgical stapling instrument in shape and orientation; and
an actuation mechanism disposed in mechanical cooperation with at least one of the first jaw member and the second jaw member, wherein actuation of the actuation mechanism moves at least one of the first and second jaw members between an approximated position for clamping tissue and an open position with respect to the other jaw member, the actuation mechanism holding the jaw members in the approximated position and having an actuator graspable by a user for releasing the actuation mechanism;
wherein the attachable clamp is removable from and re-attachable to the surgical stapling instrument.

22. The surgical stapling instrument and attachable clamp of claim 21 , wherein the attachment members are configured to removably attach to the elongate portion of the surgical stapling instrument.

23. The surgical stapling instrument and attachable clamp of claim 21 , wherein the actuation mechanism includes a first cam plate disposed in mechanical cooperation with the first jaw member and disposed in mechanical cooperation with a rod, and wherein translation of the rod causes the first jaw member to move up
