Abstract
A surgical clip with adjustable bias spring. The surgical clip includes a moveable slide assembly, whereby the positionning of the slide relative to the clip adjusts the relative compression or extension of the biasing spring.

1. A surgical clip comprising:
a first jaw component having a first body element and a first jaw element extending therefrom;
a second jaw component having a second body element and second jaw element extending therefrom, the second body element being in a telescoping relationship with the first body element, and the first and second jaw elements being moveable toward and away from one another;
a slide moveable along a longitudinal axis defined by the first and second body elements, the slide being securable at two or more locations along the axis; and a spring for biasing the first and second jaws together in a closed position, the spring being engaged at one end with the slide such that the relative biasing force exerted by the spring is dependent upon the location of the slide along the axis.
a first jaw component having a first body element and a first jaw element extending therefrom;
a second jaw component having a second body element and second jaw element extending therefrom, the second body element being in a telescoping relationship with the first body element, and the first and second jaw elements being moveable toward and away from one another;
a slide moveable along a longitudinal axis defined by the first and second body elements, the slide being securable at two or more locations along the axis; and a spring for biasing the first and second jaws together in a closed position, the spring being engaged at one end with the slide such that the relative biasing force exerted by the spring is dependent upon the location of the slide along the axis.
2. The surgical clip of claim 1 wherein the slide is securable at predetermined fixed locations along the axis.
3. The surgical clip of claim 1 wherein the slide is rotatable about the axis.
4. The surgical clip of claim 1 further comprising a threaded stem with the slide threaded onto the stem, the stem being oriented along the axis and fixed relative to either the first or second body element.
5. The surgical clip of claim 1 wherein the first and second body elements comprise inner and an outer barrels, the inner barrel telescopically slidable within the outer barrel.
6. The surgical clip of claim 1 wherein the spring is in compression.
7. The surgical clip of claim 1 wherein the spring is in tension.
8. A surgical clip comprising:
a first jaw component having a first barrel, a first jaw extending radially from one end of the first barrel, and a longitudinal slot extending from the first jaw;
a second jaw component having a second barrel, and a second jaw extending radially from one end of the second barrel and through the longitudinal slot of the first barrel, the second barrel telescopically slidable within the first barrel, and the first and second jaws being moveable toward and away from one another;
a first end cap located on the end the first barrel opposite the first jaw, the first end cap having guide slots;
a slide disposed within the first end cap, the slide being moveable along the guide slots and securable at two or more spaced apart locations along the guide slots;
a second end cap at the end of the second barrel opposite the second jaw; and a spring for biasing the first and second jaws together in a closed position, the spring residing within the barrel interiors and engaged at one end with the slide and at the other end with the second end cap.
a first jaw component having a first barrel, a first jaw extending radially from one end of the first barrel, and a longitudinal slot extending from the first jaw;
a second jaw component having a second barrel, and a second jaw extending radially from one end of the second barrel and through the longitudinal slot of the first barrel, the second barrel telescopically slidable within the first barrel, and the first and second jaws being moveable toward and away from one another;
a first end cap located on the end the first barrel opposite the first jaw, the first end cap having guide slots;
a slide disposed within the first end cap, the slide being moveable along the guide slots and securable at two or more spaced apart locations along the guide slots;
a second end cap at the end of the second barrel opposite the second jaw; and a spring for biasing the first and second jaws together in a closed position, the spring residing within the barrel interiors and engaged at one end with the slide and at the other end with the second end cap.
9. The surgical clip of claim 8 wherein the guide slots are aligned parallel to a longitudinal axis defined by the first and second barrels.
10. The surgical clip of claim 9 wherein the cap further comprises two or more notches extending from the one or more guide slots.
11. The surgical clip of claim 10 wherein the slide can be engaged in the two or more notches extending from the one or more guide slots, thereby securing the slide.
12. The surgical clip of claim 11 wherein the slide can engage the two or more notches by rotational movement of the slide about the longitudinal axis.
13. The surgical clip of claim 12 wherein the slide further comprises a slide body having one or more arms extending therefrom and a collar extending from the one or more arms, the slide arms being received through the one or more guide slots, with the collar extending around the cap.
14. A surgical clip comprising:
a first jaw component having a first barrel, a first jaw extending radially from one end of the first barrel, and a longitudinal slot extending from the first jaw;
a second jaw component having a second barrel, and a second jaw extending radially from one end of the second barrel and through the longitudinal slot of the first barrel, the second barrel telescopically slidable within the first barrel, and the first and second jaws being moveable toward and away from one another;
a first end cap located on the end the first barrel opposite the first jaw, the first end cap being rotatable about a longitudinal axis defined by the first and second barrels;
a slide disposed within the first barrel, the slide adapted for engagement with the first end cap such that rotation of the first end cap translates the slide along the axis, the slide further being securable at two or more spaced apart locations along the axis;
a second end cap at the end of the second barrel opposite the second jaw; and a spring for biasing the first and second jaws together in a closed position, the spring residing within the barrel interiors and engaged at one end with the slide and at the other end with the second end cap.
a first jaw component having a first barrel, a first jaw extending radially from one end of the first barrel, and a longitudinal slot extending from the first jaw;
a second jaw component having a second barrel, and a second jaw extending radially from one end of the second barrel and through the longitudinal slot of the first barrel, the second barrel telescopically slidable within the first barrel, and the first and second jaws being moveable toward and away from one another;
a first end cap located on the end the first barrel opposite the first jaw, the first end cap being rotatable about a longitudinal axis defined by the first and second barrels;
a slide disposed within the first barrel, the slide adapted for engagement with the first end cap such that rotation of the first end cap translates the slide along the axis, the slide further being securable at two or more spaced apart locations along the axis;
a second end cap at the end of the second barrel opposite the second jaw; and a spring for biasing the first and second jaws together in a closed position, the spring residing within the barrel interiors and engaged at one end with the slide and at the other end with the second end cap.
15. The surgical clip of claim 14 wherein the slide further includes a rib extending longitudinally of the slide that is slidably received in a corresponding slot on the first barrel.
16. The surgical clip of claim 14 wherein the slide further includes a cam surface oriented at an oblique angle to the axis, and wherein the first end cap further includes a cam pin engageable with the cam surface.
