Abstract
An improved surgical clip of the type having first and second leg members joined at their proximal ends by a resilient hinge region and terminating at their distal ends in latch means. Each leg member has an outer surface and a clamping inner surface, and the outer surface of each leg member is configured to be accepted by the jaws of the clip applier. The improvement in the clip design specifically relates to a reduction in the mass of the clip in the hinge region. A reduced mass in the hinge region lessens the strain at the hinge region when the clip is in a clamped position, and therefore increases its strength retention.
Claims10
An improved surgical clip of the type having first and second leg members joined at their proximal ends by a resilient hinge region and terminating at their distal ends in latch means, each leg member having an outer leg surface and a clamping inner surface, said clamping inner surface being in opposition to the clamping inner surface of the other leg member, the outer leg surface of each leg member being configured to be accepted by the jaws of a clip applier, and said resilient hinge region having an outer hinge surface;
- the improvement wherein the outer hinge surface of said hinge region has first and second curved valley regions, said curved valley regions spaced between a curved plateau region, and each of said curved valley regions and said curved plateau region has substantially identical radii of curvature.
An improved surgical clip of the type having first and second leg members joined at their proximal ends by a resilient hinge region and terminating at their distal ends in latch means, each leg member having an outer leg surface and a clamping inner surface, said clamping inner surface being in opposition to the clamping inner surface of the other leg member, the outer leg surface of each leg member being configured to be accepted by the jaws of a clip applier, and said resilient hinge region having an outer hinge surface;
- the improvement wherein the outer hinge surface of said hinge region has first and second rectangular valley regions, said rectangular valley regions spaced between a rectangular plateau region.
An improved surgical clip of the type having first and second leg members joined at their proximal ends by a resilient hinge region and terminating at their distal ends in latch means, each leg member having an outer leg surface and a clamping inner surface, said clamping inner surface being in opposition to the clamping inner surface of the other leg member, the outer leg surface of each leg member being configured to be accepted by the jaws of a clip applier, and said resilient hinge region having an outer hinge surface;
- the improvement wherein the outer hinge surface of said hinge region has first and second triangular valley regions, said triangular valley regions spaced between a triangular plateau region.
