ANTI-MIGRATION SURGICAL LIGATION CLIP

摘要

The present disclosure provides a surgical clip for ligating a blood vessel or tissue structure. The surgical clip includes a first leg member including a first inner surface and a first plurality of protrusions disposed on the first inner surfaces. The surgical clip also includes a second leg member including a second inner surface and a second plurality of protrusions disposed on the second inner surface. The surgical clip further includes a hinge member joining the first leg member and the second leg member. The at least one of the first and second plurality of protrusions includes a gable structure that extends along a longitudinal direction of the first or second inner surface. The orientation and the geometric shape of the protrusions of the surgical clip allow for increased resistance to the migration or sliding of the clip along a longitudinal direction of the blood vessel or tissue structure, while providing a balanced closure force. The surgical clip can prevent the longitudinal migration along the blood vessel or tissue structure.
