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 clip applier comprising:

an actuation mechanism;

a body portion;

a jaw blade removably disposed within the body portion and including first and second opposed jaws operably connected to the actuation mechanism for selective movement between a spaced apart position and an approximated position 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; and

a clip cartridge removably disposed within the body portion adjacent the jaw blade and configured to store at least one surgical clip therein, the clip cartridge having a proximal nub and a distal nub, wherein the proximal nub of the clip cartridge abuts a proximal end of the shank section of the jaw blade, and the distal nub of the clip cartridge abuts a distal end of the shank section of the jaw blade.

2. The surgical clip applier of claim 1, wherein the distal nub of the clip cartridge is disposed between the proximal ends of the first and second opposed jaws.

3. The surgical clip applier of claim 1, wherein the first and second opposed jaws of the jaw blade are symmetrically disposed along a longitudinal axis of the shank section.

4. The surgical clip applier of claim 1, wherein the first and second opposed jaws of the jaw blade define an open cavity, such that the open cavity tapers to the distal end of the shank section of the jaw blade.

5. The surgical clip applier of claim 1, wherein the spaced apart position of the opposed jaws of the jaw blade defines a width and the at least one surgical clip disposed in the clip cartridge has an unformed width, such that the width defined by the opposed jaws corresponds to the unformed width of the at least one surgical clip.

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

7. The surgical clip applier of claim 1, wherein the actuation mechanism consists of a handle assembly including a moveable handle and a stationary grip, such that the jaw blade is operably connected to the handle assembly for selective closure upon actuation of the moveable handle.

8. A method of applying a surgical clip, comprising:

providing a surgical clip applier, the surgical clip applier including an actuation mechanism and a body portion;

providing a jaw blade, the jaw blade being removably disposed within the body portion and including first and second opposed jaws operably connected to the actuation mechanism for selective movement between a spaced apart position and an approximated position 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; and

providing a clip cartridge, the clip cartridge being removably disposed within the body portion adjacent the jaw blade and configured to store at least one surgical clip therein, the clip cartridge having a proximal nub and a distal nub, such that the proximal nub of the clip cartridge abuts a proximal end of the shank section of the jaw blade, and the distal nub of the clip cartridge abuts a distal end of the shank section of the jaw blade;

inserting the jaw blade into the body portion of the surgical clip applier;

inserting the clip cartridge into the body portion; and

actuating the actuation mechanism of the surgical clip applier, the actuation mechanism directing the surgical clip disposed in the clip cartridge to be loaded into the opposing jaws of the jaw blade, the actuation mechanism further causing cooperative movement of the opposing jaws of the jaw blade from the spaced apart position to the approximated position effectuating closure of the surgical clip disposed therein.

9. The method of applying a surgical clip of claim 8, further comprising:

providing a plurality of clip cartridges, wherein each respective clip cartridge includes a different unformed surgical clip width disposed therein;

providing a plurality of jaw blades, such that a width defined by the opposing jaws of the jaw blades in the spaced apart position corresponds respectively to the different unformed surgical clips widths of the surgical clips disposed within the respective clip cartridges;

selecting a specific unformed surgical clip width and a corresponding surgical clip cartridge;

selecting a jaw blade wherein the width of the opposing jaws corresponds to the selected surgical clip cartridge;

inserting the selected jaw blade into the body portion of the surgical clip applier;

inserting the selected clip cartridge into the body portion; and

actuating the actuation mechanism of the surgical clip applier, the actuation mechanism directing the surgical clip disposed in the selected clip cartridge to be loaded into the opposing jaws of the selected jaw blade, the actuation mechanism further causing cooperative movement of the opposing jaws of the selected jaw blade from the spaced apart position to the approximated position effectuating closure of the surgical clip disposed therein.

10. A kit, comprising:

a package containing,

a clip cartridge having a proximal nub and a distal nub, the clip cartridge being loaded with a plurality of surgical clips, wherein each surgical clip defines a width; and

a jaw blade including a shank section and first and second opposed jaws, the jaw blade being configured for selective connection to an actuation mechanism of a surgical clip applier for selective movement between a spaced apart position and an approximated position to effectuate closure of a surgical clip, wherein a width defined by the opposing jaws of the jaw blade, when in the spaced apart position, corresponds respectively to the width of the surgical clips of the clip cartridge, and wherein the proximal nub of the clip cartridge is configured to abut a proximal end of the shank section of the jaw blade while the distal nub of the clip cartridge abuts a distal end of the shank section of the jaw blade.

11. The kit of claim 10, wherein the package further includes a clip applier, the clip applier including an actuation mechanism and a body portion, the body portion being configured to removably receive the jaw blade and the clip cartridge therein.

12. The kit of claim 11, wherein the package further includes:

a plurality of clip cartridges, wherein each respective clip cartridge includes a surgical clip disposed therein defining a respective unformed surgical clip width; and

a plurality of jaw blades, such that the width defined by the opposing jaws of the jaw blades correspond to the respective widths of the unformed surgical clips disposed within the plurality of clip cartridge.

13. The kit of claim 12, wherein the package further includes instructions for use.

14. The kit of claim 10, wherein the package further includes:

a plurality of clip cartridges, wherein each respective clip cartridge includes a surgical clip disposed therein defining a respective unformed surgical clip width; and

a plurality of jaw blades, such that the width defined by the opposing jaws of the jaw blades correspond to the respective widths of the unformed surgical clips disposed within the plurality of clip cartridge.
