  • Patent number: 5487746
    Abstract: A surgical clip having a double-leg side and a single-leg side. When the surgical clip is closed, the movement of the single-leg side towards the double-leg side displaces the tissue being clamped through a longitudinal opening between the legs forming the double-leg side. In order to increase the gripping area of the clip, the gripping surface of the single leg is a rounded wedge shape with smooth edges (not sharp) which are parallel to the inboard side of the double legs. The rounded wedge shape is used in order to avoid cutting the clamped tissue. When the surgical clip engages with tissue to be clamped, a plane of the tissue is displaced at the clamping region which increases the force needed to displace the clip from the tissue being clamped.
