Abstract

A dual staple disposable surgical gun, wherein the gun fires two staples in a staggered formation simultaneously to close an incision in the skin to prevent the skin overlapping. The dual staple disposable surgical gun comprises a frame structure, adapted to be held by a hand with a grip having a handle. A first staple track and a second staple track each with an advancing blade and a spring mechanism is incorporated to aid in the injection of the staples. A translatable driver manually actuates both staple tracks to eject a single pair of staples simultaneously when the dual staple disposable surgical gun is squeezed. The dual staple disposable surgical gun additionally includes a biasing means for returning the translatable driver from a staple ejecting position to a staple reloading position.

Claims

1. A dual staple disposable surgical gun, wherein the gun fires two staples in a staggered formation simultaneously to close an incision with two staggered staples in the skin without the skin overlapping comprising of:

a. a frame structure, adapted to be held by a hand with a grip having a handle;

b. a first staple track and a second staple track each with an advancing blade and a spring mechanism, wherein the first staple track is disposed on top of the second staple track in a staggered relationship, each staple track being adapted for holding staples;

c. a translatable driver for manually actuating both staple tracks to eject a single pair of staples simultaneously by the hand, wherein the pair of staggered staples eject simultaneously for engagement on either side of the incision forming a mattress suture and wherein the first staple engages a first arm close to a first edge of the incision and a second arm a distance from a second edge of the incision and the second staple engages a first arm close to a second edge of the wound and the second arm engages a distance from the first edge of the incision to achieve dual staple mattress suturing; and

d. biasing means for returning the translatable driver from a staple ejecting position to a staple reloading position; and

the translatable driver having a force transmission member linking together the translatable driver and a connecting end portion engageable with a spring connected to the translatable trigger portion.

2. The dual staple disposable surgical gun of claim 1, wherein the frame structure comprises a first staple track portion inserted into a second holder portion.

3. The dual staple disposable surgical gun of claim 1, wherein the first and second staple tracks each comprise a back and a top and the first and second staple tracks are connected back to back.

4. The dual staple disposable surgical gun of claim 1, wherein the gun uses staples that have a skin piercing projection comprising a point projection, a chiseled projection, a skewed projection, or combinations thereof.

5. The dual staple disposable surgical gun of claim 1, wherein the staple comprises a lightweight, non-rusting alloy of a metal.

6. The dual staple disposable surgical gun of claim 1, wherein the gun is formed from a crystalline polymer, or a metal.

7. The dual staple disposable surgical gun of claim 1, wherein the staples each comprises:

a. a height ranging from 4 mm to 6 mm;

b. a length ranging from 2 cm to 3 cm; and

c. a diameter of the rod ranging from 0.5 mm to 0.8 mm.

8. The dual staple disposable surgical gun of claim 1, wherein the dual stapler fires at least two staples simultaneously each time it is fired.

9. The dual staple disposable surgical gun of claim 8, wherein the two staples are in a staggered in position from each other across the incision after firing.

10. A method for surgically stapling an incision using the simultaneous ejection of offset twin surgical staples comprising the steps of:

a. inserting surgical staples into a dual staple disposable surgical gun;

b. wherein the surgical staples each comprises;

(a) a crown comprising two ends, a first arm, and a second arm attached at each end of the crown, wherein the arms comprise a skin piercing projection, wherein the arms extend from the crown in a direction substantially perpendicular to the crown when the staple is in its initial shape; and

(b) wherein the dual staple disposable surgical gun comprises a gun that fires two staples simultaneous to close an incision in the skin without the skin overlapping;

c. placing the dual staple disposable surgical gun over the incision;

d. activating the stapler by squeezing a grip to simultaneously insert a first staple from a first track and a second staple from a second track into the skin, enabling;

(a) the first arm of each staple to engage the skin nearest the incision on opposite sides of the incision;

(b) the crowns of each staple to locate adjacent and parallel to one another; and

(c) the second arm of each staple to engage the skin away from the incision on opposite sides of the incision; and

e. using the dual staple disposable surgical gun to bend each arm on the staples forming an inverted G-shape with a gap.

11. The method of claim 10, wherein the step of using the dual staple disposable surgical gun bends each arm to ensure that the first arms intersects the incision.

12. The method of claim 10, wherein the step of using the dual staple disposable surgical gun bends each arm thereby closing the incision in the skin without the skin overlapping.
