| Abstract: |
A surgical clip, particularly adapted to produce necrosis in Fallopian tube tissue, consists of jaws hinged adjacent one end and a U-shaped spring which holds the jaws open in one position and exerts a closing pressure on the jaws in another position. When the spring is in the jaws closing position, the bridge portion thereof in conjunction with side flanges carried by one of the jaws provides a smoothly contoured hinge end thereby reducing to a minimum zones for the entrapment of tissue which might be the cause of adhesions.

We claim:
1. A surgical clip for occluding tubes in a living animal, said clip comprising first and second jaw members; means adjacent one end of each jaw member for pivotally mounting the other ends of said jaw members for movement toward each other to a closed position and away from each other to an open position; said pivotal mounting means including a pair of side flanges at said one end of the first jaw member, an arcuate recess between said side flanges, a pivot pin receiving bore in said side flanges the axis of which lies on a radius of said arcuate recess, said one end of the second jaw member having a width to be snugly received between the pair of side flanges of said first jaw member, an arcuate bearing element on said second jaw member adapted to be received in the arcuate recess of the first member, a transverse pivot pin receiving bore in the arcuate bearing element, the axis of said pivot pin receiving bore lying on a radius of the bearing element and co-axial with the bores in the side flanges and a pivot pin in said bore in side flanges and the bore in the arcuate bearing element; a generally U-shaped spring member consisting of a pair of legs and a connecting bridge portion, the pair of legs engaging remote surfaces of each jaw member and slidable from a first position on one side of the pivotal mounting to urge said jaw members into the open position to a second position on the other side of said pivotal mounting, to urge said jaw members into the closed position and, when the spring member is in the jaws closing position, the free end of each of the pair of legs of said U-shaped spring member having an inturned portion, a longitudinal U-shaped spring member receiving groove in each said first and second jaw members, said longitudinal groove terminating rearwardly of said pivot pin and forming with the inturned ends of the U-shaped spring stop members for the U-shaped spring when the spring is in said first position, the bridge portion thereof in conjunction with said side flanges carried by said first jaw member providing a smoothly contoured hinge end thereby reducing to a minimum zones for the entrapment of tissue which might be the cause of adhesions.
