Endoscopic surgical clip
View Patent ↗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.
1. A spring clip for occluding a vessel comprising:
a planar base;
a jaw in a substantially planar arrangement with the base, the jaw including substantially coplanar elongate first and second arms having front and tail ends, the tail ends being in flexible communication with the base to define a first longitudinal plane, the front ends being moveable from a first state to a second state along an axis perpendicular to the first longitudinal plane, wherein the first arm is spaced apart from the second arm defining a slot therebetween configured to receive and occlude a vessel, the slot having a width less than a width of either the first or second arms and defining a second longitudinal plane extending perpendicular to the first longitudinal plane; and
a tab disposed on the front end of each of the first and second arms wherein at least a portion of each tab extends through the second longitudinal plane when the first and second arms are in the first and second states and at least a portion of each tab are in contact with each other when the front ends are in the first state and the tabs are vertically spaced apart when the front ends are in the second state.
2. The spring clip of claim 1 , wherein the tabs are arcuately shaped.
3. The spring clip of claim 2 , wherein the first arm is in a substantially planar arrangement with the second arm along a longitudinal axis.
4. The spring clip of claim 3 , wherein a retention mechanism is disposed perpendicularly to the longitudinal axis to urge the first and second arms into a predetermined relationship.
5. The spring clip of claim 1 , wherein the tab of the first arm extends orthogonally towards the second arm.
6. The spring clip of claim 5 , wherein the first arm is longer than the second arm.
7. The clip of claim 6 , wherein the tail ends of the first and second arms communicate with the back end portion of the base.
8. The spring clip of claim 1 , wherein the arms are substantially equal in length.
9. The spring clip of claim 1 , wherein each of the arms further includes at least one socket for receiving a biasing mechanism.
10. The clip of claim 1 , wherein a bottom face of the tab disposed on the first arm is in contact with a top face of the tab disposed on the second arm.
11. The clip of claim 1 , wherein the tabs are vertically positioned along a vertical axis in both the first and second states.
12. The clip of claim 1 , wherein at least one of the tabs extends across a longitudinal axis.
