Ligation clip and preparation method thereof

Abstract

The present disclosure provides an absorbable biomedical polymer material, a ligating clip, and a method for preparing a ligating clip. In the present disclosure, the absorbable biomedical polymer material is composed of a first polymer and a second polymer, the first polymer consists of 50 wt % to 100 wt % poly-L-lactide and 0 wt % to 50 wt % polyglycolide, and the second polymer is polydioxanone. The absorbable biomedical polymer material has appropriate rigidity and toughness, and may be applied to prepare a medical device such as a ligating clip. The absorbable ligating clip has appropriate rigidity and toughness, especially when it contains 2.5 wt % to 40 wt % of the first polymer, facilitating piercing through a fascia and resisting plastic deformation at a bending point. Finally, the present disclosure further provides some structural forms of the ligating clip and the method for preparing the ligating clip.
