Abstract

A surgical clip applier includes an actuation mechanism, a body portion, a jaw blade, and a clip cartridge, the jaw blade and clip cartridge removeably disposed within the body portion. The jaw blade including first and second opposed jaws operably connected to the actuation mechanism to effectuate closure of a surgical clip, the first and second opposed jaws connected to each other at a proximal end by a shank section. The clip cartridge disposed within the body portion adjacent to the jaw blade and configured to store at least one surgical clip therein. The clip cartridge having a first nub which abuts a first end of the shank section of the jaw blade, and a second nub which abuts a second end of the shank section of the jaw blade, such that longitudinal and vertical movement of the jaw blade is arrested.

Claims

1. A surgical instrument for applying fasteners, the surgical instrument comprising:

a jaw assembly including a shank, a first jaw and a second jaw, a proximal portion of the first jaw is connected to the shank, a proximal portion of the second jaw is connected to the shank, the first jaw and the second jaw are configured for relative movement between a spaced apart position and an approximated position; and

a cartridge disposed in mechanical cooperation with the jaw assembly, the cartridge including a proximal nub and a distal nub, wherein the proximal nub of the cartridge abuts a proximal end of the shank of the jaw assembly, and the distal nub of the cartridge abuts a distal end of the shank of the jaw assembly.

2. The surgical instrument according to claim 1, wherein the distal nub of the cartridge is disposed between the proximal portion of the first jaw and the proximal portion of the second jaw.

3. The surgical instrument according to claim 1, wherein the first jaw and the second jaw are symmetrically disposed along a longitudinal axis of the shank.

4. The surgical instrument according to claim 1, wherein the first jaw and the second jaw define an open cavity, wherein the open cavity tapers to the distal end of the shank of the jaw assembly.

5. The surgical instrument according to claim 1, wherein the spaced apart position of the first jaw and the second jaw defines a width which corresponds to an unformed width of a surgical fastener.

6. The surgical instrument according to claim 1, wherein at least one of the proximal nub of the cartridge and the distal nub of the cartridge is a cylindrical pin.

7. The surgical instrument according to claim 1, further comprising a body portion, the jaw assembly removably disposed at least partially within the body portion.

8. The surgical instrument according to claim 1, further comprising an actuation assembly disposed in mechanical cooperation with the jaw assembly and configured to effect the relative movement of the first jaw and the second jaw between the spaced apart position and the approximated position.

9. The surgical instrument according to claim 1, wherein the shank of the jaw assembly defines a first plane, and wherein a distal portion of the first jaw of the jaw assembly is disposed along a second plane, the first plane is disposed at an angle with respect to the second plane.

10. The surgical instrument according to claim 9, wherein a distal portion of the second jaw of the jaw assembly is disposed along the second plane.

11. The surgical instrument according to claim 10, wherein a proximal portion of the cartridge is disposed along a third plane, the third plane is parallel to the first plane.

12. The surgical instrument according to claim 11, wherein a distal portion of the cartridge is disposed along a fourth plane, the fourth plane is parallel to the second plane.

13. A kit, comprising:

a surgical fastener; and

a surgical instrument for applying surgical fasteners, the surgical instrument comprising;

a jaw assembly including a shank, a first jaw and a second jaw, a proximal portion of the first jaw is connected to the shank, a proximal portion of the second jaw is connected to the shank, the first jaw and a second jaw are configured for relative movement between a spaced apart position and an approximated position to at least partially compress the surgical fastener therebetween; and

a cartridge disposed in mechanical cooperation with the jaw assembly, the cartridge including a proximal nub and a distal nub, wherein the proximal nub of the cartridge abuts a proximal end of the shank of the jaw assembly, and the distal nub of the cartridge abuts a distal end of the shank of the jaw assembly.

14. The kit according to claim 13, further including a clip applier having an actuation mechanism and a body portion, the body portion configured to removably engage the jaw assembly and the cartridge.
