Abstract

A septal stapling apparatus includes an instrument body having proximal and distal end portions. A handle at the distal end portion enables a user to hold and manipulate the instrument body. A pair of spaced apart arms are extending from the handle and include a staple arm and a tensioning arm. The body provides a trigger that moves between resting and firing positions. An actuator link moves between first and second positions, the actuator link being moved by the trigger, wherein the actuator link includes a staple moving member that is attached to the staple arm. The staple arm has a staple bank that includes multiple staples. The trigger, actuator link, staple bank, and staple moving member are configured to move a staple to a stapling position when the trigger is pulled. The staple arm and tensioning arm move together when the trigger is pulled.

f) the staple arm having a staple bank that includes multiple staples;

g) wherein a gap exists between the staple arm and the tensioning arm when the trigger is in the resting position and when the trigger is in the firing position;

h) wherein the trigger, actuator link, staple bank and staple moving member are configured to move a staple to stapling position when the trigger is pulled from the resting position to the firing position;

i) wherein the tensioning arm is configured to move toward the staple arm when the trigger is pulled from the resting position to the firing position; and

j) wherein the trigger is configured to move in a line parallel to the staple arm when the trigger is pulled from the resting position to the firing position.

2. The nasal septal stapling apparatus of claim 1 wherein the tensioning arm has a receptacle that receives at least a part of a staple during a stapling operation and wherein the tensioning arm comprises a concavity configured to engage a camming surface of the trigger.

3. The nasal septal stapling apparatus of claim 2 wherein the trigger is configured to engage a lever that rotates when the trigger is depressed and wherein the lever is configured to push on the actuator link when the lever rotates.

4. The nasal septal stapling apparatus of claim 1 wherein the gap exists between the staple arm and the tensioning arm proximal to where the tensioning arm and staple arm extend from the body.

5. The nasal septal stapling apparatus of claim 1 wherein the staple arm is fixed relative to the body.

6. The nasal septal stapling apparatus of claim 1 wherein the actuator link slides relative to the body.

7. The nasal septal stapling apparatus of claim 6 wherein the actuator link slides and simultaneously causes the staple moving member to pivot, engaging and dispensing a staple from the staple magazine.

8. The nasal septal stapling apparatus of claim 1 wherein the actuator link and staple moving member are pivotally attached.

9. The nasal septal stapling apparatus of claim 1 wherein the staple arm and tensioning arm each have head portions that dispense a staple when the trigger is pulled.

28. The nasal septal stapling apparatus of claim 1 or 10, wherein when the trigger is pulled, a majority of the length of the staple arm is spaced apart from the tensioning arm to accommodate the nasal septum, including the columella, during stapling.

29. The nasal septal stapling apparatus of claim 1 or 10, wherein the staple arm has a longitudinal axis and the staple bank protrudes away from the staple arm longitudinal axis, and wherein the tensioning arm has a longitudinal axis and the tensioning arm has an anvil that protrudes away from the longitudinal axis of the tensioning arm.

30. The nasal septal stapling apparatus of claim 1 or 10, wherein the tensioning arm has an anvil that protrudes toward the staple bank and wherein the gap is in between the staple bank and the anvil of the tensioning arm when the trigger is pulled.

31. The nasal septal stapling apparatus of claim 1 or 10, wherein the gap is in between the staple bank and the tensioning arm when the trigger is pulled.

10. A nasal septal stapling apparatus, comprising:

a) an instrument body having proximal and distal end portions;

b) a handle on the instrument body that enables a user to hold and manipulate the instrument body;

c) a pair of spaced apart arms extending from the handle including a staple arm and a tensioning arm, each arm having a distal end portion with a stapling portion thereon;

d) the body having a trigger that moves between resting and firing positions;

e) an actuator link that moves between resting and firing positions, the actuator link being moved by the trigger, wherein the actuator link includes a staple moving member that is attached to the staple arm at the distal end portion thereof, said staple moving member comprising part of the stapling portion of the staple arm;

f) the staple arm having a staple bank that includes multiple staples;

g) wherein the trigger, actuator link, staple bank and staple moving member are configured to move a staple to a stapling position when the trigger is pulled;

h) wherein the tensioning arm is configured to move toward the staple arm when the trigger is pulled from the resting position to the firing position;

i) wherein the staple arm and the tensioning arm are spaced to accommodate a patient'"'"'s columella when the trigger is in the resting position and when the trigger is in the firing position; and

j) wherein the trigger is configured to move in a line parallel to the staple arm when the trigger is pulled from the resting position to the firing position.

11. The nasal septal stapling apparatus of claim 10 wherein the tensioning arm has a receptacle that receives at least a part of a staple during a stapling operation.

12. The nasal septal stapling apparatus of claim 10 wherein the tensioning arm pivots relative to the body.

13. The nasal septal stapling apparatus of claim 10 wherein the staple arm is fixed relative to the body.

14. The nasal septal stapling apparatus of claim 10 wherein the trigger is configured to engage a lever that rotates when the trigger is depressed and wherein the lever is configured to push on the actuator link when the lever rotates.

15. The nasal septal stapling apparatus of claim 10 wherein the actuator link and staple moving member are pivotally affached.

16. The nasal septal stapling apparatus of claim 15 wherein the actuator slides and simultaneously causes the staple moving member to pivot, engaging and dispensing a staple from the staple magazine.

17. The nasal septal stapling apparatus of claim 10 wherein the staple arm houses a staple magazine.

18. The nasal septal stapling apparatus of claim 10 wherein the staple arm and tensioning arm each have head portions that dispense a staple when the trigger is pulled.
