Abstract

A surgical spring clip is provided for use in minimally invasive surgical procedures. The clip has a flat planar plate shape having pair of arms connected by a base, all generally positioned within a single plane. The arms are elongate linear cantilevered beams extending beyond the base and are biased to a first or closed position generally within the plane. The base and arms define a slot for the positioning of and receiving a vessel and occluding the flow therethrough.

Claims

1. A surgical spring clip for occluding a vessel, comprising:

a rigid substantially planar base;

a jaw in a substantially planar arrangement with the base and including first and second elongate arms, the first and second arms being disposed in a substantially coplanar arrangement in a first, closed position of the clip, the arms being substantially parallel to and spaced apart from each other, the arms defining a longitudinal plane extending therebetween and defining a slot having a width less than a width of either the first or second arms, the arms further having front and tail ends, the front ends flexibly extending perpendicular from the base from the first closed position to a vertically spaced apart second position; and

a tab disposed on the front end of each of the first and second elongate arms wherein at least a portion of each of the tabs extends through a longitudinal plane bisecting the slot and are in contact with each other when the front ends are in the first, closed position and at least a portion of each tab extends through the longitudinal plane bisecting the slot and are vertically spaced apart and at least a portion of each tab extends through the longitudinal plane bisecting the slot when the front ends are in the second position.

2. The clip of claim 1, wherein at least one of the tabs forms a distal end of the slot.

3. The clip of claim 1, wherein at least one tab is oriented towards the slot.

4. The clip of claim 3, wherein the at least one tab extends beyond a centerline of the slot.

5. The clip of claim 1, wherein the first arm is substantially equal in length to the second arm.

6. The clip of claim 4, wherein the first arm is longer than the second arm and includes a tab oriented to transect an imaginary line extending from the centerline of the slot.

7. The clip of claim 1, wherein a bottom face of the tab disposed on the first elongate arm is in contact with a top face of the tab disposed on the second elongate arm.

8. The clip of claim 1, wherein the tabs are vertically positioned along a vertical axis in both the first and second positions.

9. The clip of claim 1, wherein each tab extends beyond a centerline of the slot.

10. A surgical spring clip for occluding a vessel, comprising:

a rigid planar base;

a jaw including first and second elongate arms, the arms being substantially parallel to each other in a substantially planar arrangement, wherein the arms are spaced apart from each other and define an elongated slot therebetween, the slot having a width less than a width of either the first or second arms; and

a pair of tabs disposed on the front end of each of the first and second elongate arms, wherein at least a portion of each of the tabs extends beyond the width of the slot when the arms are in a first, closed position and when the arms are in a second open, vertically spaced apart, position for the reception of a vessel therebetween.

11. The clip of claim 10, wherein a bottom face of the tab disposed on the first elongate arm is in contact with a top face of the tab disposed on the second elongate arm.

12. The clip of claim 10, wherein the tab is vertically positioned along a vertical axis in both the first and second positions.

13. A surgical spring clip for occluding a vessel, comprising:

a rigid planar base;

a jaw including first and second elongate arms, the arms being substantially parallel to each other in a substantially planar arrangement, wherein the first arm is substantially equal in length to the second arm and the arms are spaced apart from each other to define an elongated slot therebetween, the slot having a width less than a width of either the first or second arms; and

a tab disposed on the front end of at least one of the first and second elongate arms wherein at least a portion of the tab extends beyond the width of the slot when the arms are in a first, closed position and when the arms are in a second open, vertically spaced apart, position for the reception of a vessel therebetween.

14. The clip of claim 13, wherein the tab is vertically positioned along a vertical axis in both the first and second positions.
